Best 18 Inch Pizza Ovens: Top 9 Picks (November 2026)
The best 18 inch pizza ovens include the PIEZANO XL 14" Electric Pizza Oven Indoor for indoor countertop baking, the CROSSON ETL listed Commercial Double Deck for high-volume indoor batches, and the BIG HORN Gas Pizza Oven for fast outdoor family pizzas.
On this page (6 sections)
The best 18 inch pizza oven for most large-pie cooks is the Ooni Koda 2 Pro. Its 18 inch rear cooking surface gives you room for oversized pizzas, cast iron or sheet pans, while propane power keeps outdoor setup simple.
An 18 inch oven is mainly about serving capacity. Compared with a 12 inch model, the larger surface gives you more room to shape a big pie and more flexibility for cooking food that will not fit on a small stone.

PIEZANO XL 14" Electric Pizza Oven Indoor: Best for indoor countertop baking
- 14 inch ceramic pizza stone
- Heats to 800°F
- Dual heat controls
- 1200W electric power
The Piezano brings high-heat stone baking to an indoor countertop. Its 14 inch cooking surface is smaller than a true 18 inch oven, but it suits kitchens where propane and wood are not practical.
Pros
- Indoor electric design
- 800°F maximum temperature
- Removable ceramic stone
Cons
- Smaller than the 16 and 18 inch outdoor picks
- Needs a 3-prong outlet
The PIEZANO XL is an indoor countertop oven for cooks who want high heat without propane, wood or an outdoor setup. Its 14 inch natural ceramic stone gives you more room than a 12 inch oven, although it does not match the cooking area of a true 18 inch model.
The oven reaches 800°F and uses separate upper and lower heat controls. That lets you adjust the top and bottom heating elements independently when you want more cheese browning or a firmer base, rather than relying on a single setting.
It runs on 1200W electric power through a 3-prong plug, so you will need a suitable grounded outlet within reach of the counter. The removable stone helps with cleanup, while the included pizza peel helps move pizzas on and off the cooking surface.
The 14 inch size is best for cooks who want larger-than-standard home pizzas but do not have room for an outdoor oven. It can also handle calzones, flatbreads and reheated slices, which makes it useful beyond Friday pizza night.
Set it up on a stable counter where the dropdown door can open without hitting other appliances. Give the stone time to heat through before baking, and let it cool before you wash or store it.
CROSSON ETL listed Commercial Double Deck: Best for high-volume indoor batches
- Two independent decks
- Fits pizzas up to 16 inches
- 3600W electric power
- 60-minute timer
CROSSON is built for repeated indoor baking rather than portability. Two decks let you manage more than one pizza at a time, although each deck is smaller than an 18 inch cooking surface.
Pros
- Two shelves for batch cooking
- Independent upper and lower controls
- Stainless steel construction
Cons
- 71.9 lb weight
- Needs 3600W electrical power
The CROSSON is the strongest indoor choice for repeated batches because it has two independent decks. Each deck can handle pizzas up to 16 inches, so it offers more serving capacity than a single compact countertop oven.
Independent upper and lower temperature controls let you manage each deck separately. The oven also has a 60-minute timer, audible alarm and oven light, which help when several pizzas are moving through the bake cycle.
Its stainless steel exterior and aluminized steel interiors suit a commercial-style indoor setup. At 71.9 lb and 23 in wide, it needs a sturdy, permanent countertop position rather than a shelf you move around.
Choose CROSSON when your priority is indoor throughput rather than portability. It does not provide an 18 inch cooking surface, but the double-deck layout can be more useful than one large chamber when you serve several pizzas.
The 3600W power demand is a serious trade-off, so check that your kitchen circuit can support it before you plan a permanent spot. The full insulation on all sides helps hold steady heat, but also adds to the size and weight.
BIG HORN Gas Pizza Oven: Best for fast outdoor family pizzas
- 15 inch cooking capacity
- 23,000 BTU dual-side burners
- 750°F heat in 10 minutes
- Stainless steel body
BIG HORN offers fast outdoor cooking in a portable countertop format. It is not a full 18 inch oven, but its 15 inch capacity gives families more room than a typical 12 inch model.
Pros
- Dual independent burner controls
- Built-in thermometer
- Portable stainless steel design
Cons
- Does not fit an 18 inch pizza
- Requires propane outdoors
The BIG HORN Gas Pizza Oven suits outdoor cooks who want fast family pizzas in a portable format. Its stated capacity fits up to a 14.7 inch pizza, placing it between common 12 inch ovens and the larger 16 inch and 18 inch options.
The dual-side burners provide 23,000 BTU and heat the oven to 750°F in 10 minutes, with a maximum stated temperature above that. The arc-shaped chamber is meant to circulate heat evenly, so you should need less rotation during a short bake.
The oven uses a stainless steel body, built-in thermometer and two control knobs for separate heat adjustment. That gives you a clear way to watch the chamber temperature and tame a flame that is browning one side too fast.
A foldable pizza peel, pizza stone and propane regulator hose are included. The removable door and anti-skid feet are useful details for outdoor setup, storage and tabletop cooking.
Choose it when 15 inch capacity is enough for your household. If you regularly make 18 inch pies, the cooking area will feel restrictive even though the oven is designed for quick outdoor baking.
HALO Versa 16 Outdoor Pizza Oven: Best for hands-free rotating bakes
- 16 inch motorized rotating stone
- 360-degree rotation
- 750°F stone temperature
- Propane power
The HALO Versa 16 gives you a rotating cooking surface for large outdoor pizzas. It falls short of 18 inches, but the motorized stone can reduce the need for manual turning during a bake.
Pros
- 16 inch cooking stone
- Rotating cooking surface
- Works with 20 lb tanks and 1 lb canisters
Cons
- Smaller than the Ooni 18 inch surface
- Gas-only outdoor setup
The HALO Versa 16 is a good fit for cooks who want a large outdoor surface without manually turning the pizza as often. Its 16 inch motorized cordierite stone rotates 360 degrees during cooking.
The oven reaches a 750°F stone temperature in 12 minutes, and the brand says pizzas can cook in 5 minutes. Its U-shaped convection and infrared heating design is intended to distribute heat across the cooking area.
Propane powers the oven, and it can connect to either a 20 lb LP tank or a 1 lb canister. That gives you flexibility for a backyard station, tailgate or campsite, without tying you to one tank size.
The Versa 16 does not fit the full 18 inch target, but the rotating stone may be more convenient for cooks who value hands-free turning. Choose it when even rotation matters more than the last 2 inches of surface.
At 43.5 lb, it is portable for an outdoor oven but not light enough to haul by hand without care. Use a stable table or stand, and keep the fuel side clear while the stone is hot.
CHEFMAN Indoor Pizza Oven: Best for preset indoor recipes
- Fits 12 inch pizzas
- Five touchscreen presets
- 300–800°F range
- Pizza stone and peel included
CHEFMAN is the easiest fit for cooks who want indoor presets instead of an oversized outdoor oven. Its 12 inch capacity is the smallest here, so it suits individual servings more than party-size pies.
Pros
- Five pizza presets
- Touchscreen controls
- Double-paned window
Cons
- Only fits 12 inch pizzas
- Not designed for outdoor oversized pies
The CHEFMAN is the best space-saving indoor option for cooks who prefer guided settings. For frozen-pizza focused picks, see indoor pizza ovens for frozen pizza.
It fits 12 inch pizzas and offers five touchscreen presets for Neapolitan, New York, thin-crust, pan and frozen pizza. Those presets are a practical starting point if you do not want to set top and bottom heat by feel.
Both heating elements range from 300°F to 800°F, with a manual setting for custom baking. The double-paned window helps retain heat while you prepare multiple pizzas indoors, and a dropdown door keeps the front profile compact.
A pizza stone, pizza peel and digital cookbook are included. The oven uses 1700W at 120V, so check that your countertop outlet and available space suit the appliance.
This is not an 18 inch oven, but it can be the better choice for apartments, small kitchens and individual servings. If your main goal is oversized pizza, move up to a 16 inch or 18 inch outdoor model.
BIG HORN 14-Inch Indoor Pizza Oven: Best for compact high-heat indoor baking
- 14 inch cooking capacity
- 220–850°F range
- Six preset programs
- 1800W electric power
This BIG HORN model gives indoor cooks more capacity than a 12 inch oven while keeping the footprint suited to a countertop. Six programs cover styles from frozen and New York pizza to deep dish.
Pros
- Highest stated temperature in this group
- Six cooking programs
- Flip-up design
Cons
- Smaller than a true 18 inch oven
- Requires a 110–120V electrical supply
The BIG HORN 14-Inch Indoor Pizza Oven gives indoor cooks a higher stated temperature than the other compact electric picks. It reaches 850°F, offers six preset programs and uses PID temperature control across a 220–850°F range.
Its programs include Manual, Wood Fired, Frozen, New York, Thin Crispy and Deep Dish. The 14 inch stone gives you more cooking room than the CHEFMAN while staying smaller than a full outdoor oven.
The oven uses 1800W electric power and is designed for a 110–120V supply. A pizza stone, pizza peel and user manual are included, and the flip-up design reduces its footprint for storage.
Choose this model when you want indoor control and a larger pie than 12 inches. It is a practical compromise, but it cannot provide the serving capacity or pan flexibility of a true 18 inch cooking chamber.
The 15 minute preheat is worth planning around, especially if you are cooking several pies in a row. The wrinkle black finish resists oil stains and fingerprints, which helps in a busy kitchen, but the stone still needs careful cooling before cleaning.
Ooni Koda 2 Pro Gas Pizza Oven: Best for true 18 inch outdoor cooking
- 18 inch cooking area
- Propane gas power
- 160–500°C range
- Digital temperature hub
The Ooni Koda 2 Pro is the clearest match for shoppers searching for an 18 inch pizza oven. Its large stone leaves room for oversized pizzas, cast iron or sheet pans, while propane keeps setup focused on outdoor cooking.
Pros
- Largest pizza area in this roundup
- Propane hose and regulator included
- Ambient and food-probe readings through the digital hub
Cons
- Not compatible with natural gas
- Larger footprint than compact ovens
The Ooni Koda 2 Pro is the best true 18 inch pizza oven in this roundup. Its cooking stone measures 21 inches at the front and 18 inches at the rear, creating room for large pizzas, cast iron or sheet pans.
The oven uses propane only and includes a 28 mBar regulator and gas hose. Its temperature range runs from 160°C to 500°C, giving you room to cook pizza and other foods at different heat levels.
The Ooni Connect Digital Temperature Hub provides ambient and food-probe readings to a smartphone. That extra information can help you adjust the flame before a crust goes too dark, rather than guessing from the outside.
The oven also has a pyrolytic cleaning feature, which supports a simpler cleanup routine after high-heat cooking. You still need to let the oven cool and follow the cleaning guidance for the stone.
The larger footprint is the main trade-off. Measure your outdoor counter, storage area and propane setup before choosing it, especially if you are replacing a compact 12 inch oven.
PIZZELLO 16" Outdoor Pizza Oven: Best for multi-fuel outdoor cooking
- 16 inch cooking space
- Two-layer design
- Uses wood, pellets or charcoal
- Removable center rack
PIZZELLO suits outdoor cooks who want more than one fuel option and a second cooking layer. It cannot hold an 18 inch pizza, but the removable rack gives extra flexibility for larger foods.
Pros
- Three fuel choices
- Two-layer cooking layout
- Waterproof cover included
Cons
- No timer function
- Smaller pizza surface than the 18 inch Ooni
The PIZZELLO 16 is the most flexible fuel choice here because it supports wood, pellets and charcoal. For wood-fired portability, compare portable wood pizza ovens.
Its two-layer design can hold a 16 inch pizza on the lower level while another food item cooks above. That second level is useful when you want vegetables, fish or steak ready at the same time as the pie.
The center cooking rack is removable, which gives you more room for larger foods. The package includes two 16 inch grill grates, a 16 inch pizza peel, a 16 inch pizza stone and a waterproof cover.
Adjustable legs offer two height settings, and side handles help with outdoor movement. The oven uses a freestanding setup rather than a small countertop footprint, so you will need clear ground space.
Choose PIZZELLO if smoky flavor and fuel choice matter more than fitting an 18 inch pie. For a true 18 inch pizza, the Ooni has the larger stated cooking surface, but it gives up this multi-fuel flexibility.
YeKuKing 18 Inch Pizza Pan for Oven: Best for pan-baked oversized pizzas
- 17.7 inch diameter
- Two stainless steel pans
- Oven and dishwasher safe
- Rolled edges
YeKuKing is a pan accessory rather than a pizza oven, but its 17.7 inch diameter helps cooks make large pan-baked pizzas in a compatible oven. Confirm the oven's internal clearance before using it.
Pros
- Two pans included
- Dishwasher safe
- Useful for pizza, roasting and serving
Cons
- Does not provide heat
- May not fit every 18 inch oven interior
The YeKuKing is an accessory for large-pie cooking, not a heated oven. Its 17.7 inch stainless steel diameter gives you a pan option for pizza, roasting, reheating and serving when your oven has enough internal clearance.
The package contains two round pans. Rolled edges improve handling, while the brushed stainless steel surface is designed for easier food release and cleanup.
The pans are oven safe and dishwasher safe. Their gentle slope helps contain food, but a large pan can restrict airflow or sit too close to the oven walls if the chamber is narrow.
Choose YeKuKing when you want pan-baked oversized pizza or a second large tray for gatherings. Measure the cooking chamber before ordering because an oven's advertised size may not equal its usable interior width.
The two-pack format helps when one pan is in the dishwasher and another is ready for the next batch. Use heat-resistant gloves for a large tray, since a full pan is harder to control than a peel alone.
How we compared large pizza cooking surfaces
The best 18 inch pizza oven needs more than a large outside body. We compared the stated cooking size, fuel, heat range, layout, included cooking parts and the kind of serving pattern each model supports.
An 18 inch surface is useful for oversized pies and larger cookware, but it also needs more storage and counter space. A 16 inch oven may be easier to move, while a double-deck 16 inch oven may serve more people indoors.
We also considered how much control you get over the bake. The Piezano and BIG HORN indoor ovens separate top and bottom heat, while the HALO rotates its stone and the Ooni adds digital temperature readings.
That control matters because large pizzas can brown at the edges before the center sets. Separate heat, rotation and temperature readings give you different ways to correct that balance during a bake.
Our score weighs specs, features and buyer feedback against what you are shopping for. Scores are not a promise of cooking results, and high heat still requires careful setup, timing and safe handling.
We also looked at what is included, since a peel, stone, hose or cover can change the cost and convenience of getting started. A complete kit may suit a first-time buyer better than a bare oven that needs extra parts.

What size pizza oven should you choose?
Choose an 18 inch oven when your usual pizzas are larger than 12 inches or you want room for cast iron and sheet pans. Choose 16 inches when you want a large pie but need a somewhat smaller outdoor unit.
Size is not only about pizza diameter. A larger chamber also gives you working room to launch dough, rotate a pie and keep the crust away from the walls.
That margin can make a big difference on a windy patio or when you are serving guests.
A 14 inch oven can be a useful middle ground for an indoor kitchen. The PIEZANO and BIG HORN indoor models both offer more room than 12 inch units while using countertop electric power.
A 12 inch oven still has its place in a small kitchen or for one or two servings. It heats faster in some cases, stores more easily and may be a better fit if most of your pizzas are individual size.
If you are comparing the largest options, read our guide to a 24 inch pizza oven. A 24 inch model needs more careful planning for ventilation, storage, fuel and safe working space.
Think about how you serve people, not just how big you can make a pizza. An oven that fits your counter, storage cupboard and usual group size will get used more often than a larger model that stays packed away.
Also check the shape of the cooking area, because a long chamber and a round stone can feel different in practice. A surface that is wide at the front and narrower at the back may limit how you place a very large pie.
Finally, measure before you buy and leave room for the peel handle. A pizza that fits on paper can still be awkward to launch if the door, table edge or nearby wall gets in the way.
Gas, electric or multi-fuel: which setup fits?
Propane gas suits outdoor cooks who want fast heat and no electrical connection. The Ooni Koda 2 Pro uses propane only, while the BIG HORN and HALO models also focus on outdoor gas cooking.
Electric ovens are easier to place indoors when you have a suitable outlet. The Piezano, CHEFMAN, BIG HORN 14-Inch and CROSSON avoid fuel storage, but their power needs and cooking capacities differ.
Multi-fuel ovens give you more control over flavor and fuel choice. The PIZZELLO supports wood, pellets and charcoal, so it fits cooks who want a smoky outdoor style and do not mind managing fuel and airflow.
For a basic explanation of oven types, read What Is a Pizza Oven and How Does It Work? and What Is a Pellet Pizza Oven and How Does It Work?.
How do you use a large pizza oven safely?
Use a stable, suitable surface and leave the clearances required by the oven instructions. Keep propane, wood and charcoal equipment outdoors when the model requires outdoor use, and do not assume a large oven is safe indoors.
Check the manual for the exact clearances around the sides, top and front. Heat can damage nearby cabinets, railings, umbrellas and stored fuel, so a clear zone matters more with a large oven than with a small one.
Preheat the stone or cooking surface before launching dough. Large pizzas need enough peel space and a dough shape that fits the surface without touching the oven walls.
Shape the dough slightly smaller than the stone so you have a margin on every side. A pie that touches a hot wall can stick, tear or burn before the center is cooked.
Use heat-resistant tools when turning or removing a pizza. Let stones cool before cleaning, and remove loose food debris without soaking a hot stone in water.
Let the oven cool fully before you move it or put it away. Hot stone and metal can stay dangerous long after the flame or element is off, so keep children and pets away during that time.
For gas models, check the regulator and hose connection before lighting. For wood and charcoal models, manage airflow and ash only after the fire and cooking surface have cooled.
Store fuel separately from the oven and keep a clear path to shut it off. If you smell gas, do not light the oven and follow the safety steps in the manual for the gas system you are using.
Is an 18 inch oven worth it for your household?
An 18 inch oven is worth considering when you serve several people, make oversized pizzas or want room for cookware beyond a small pizza stone. It is less useful if you mainly make individual 10 to 12 inch pies indoors.
The Ooni Koda 2 Pro is the direct choice for the largest cooking surface here. Pick CROSSON for repeated indoor batches, PIZZELLO for multi-fuel cooking, or HALO when a rotating 16 inch stone is more useful than a full 18 inch area.
The best 18 inch pizza oven is the Ooni Koda 2 Pro for large outdoor pizzas and flexible cookware. Choose a compact electric model for indoor convenience, a double-deck oven for batch service, or a multi-fuel 16 inch oven for smoky outdoor cooking.
Your choice should match where you cook most often. An outdoor propane oven will not help much if renters, weather or HOA rules keep it packed away, while a compact indoor oven may serve your household better week to week.
Consider the whole routine, from fuel storage to cleanup. A larger surface is only worth it if you have space to set it up safely and a plan for where the stone, peel and fuel will live after the meal.
If you host often, the extra room can change the meal. Guests can watch a large pie bake, and you may have space for a second dish without crowding the main pizza.
If you cook for one or two, a smaller oven can be faster to preheat and easier to clean. In that case, the money and space saved may matter more than the largest possible crust.
The right pick is the one that fits your kitchen, your fuel preference and your usual serving size. Measure first, check the power or gas setup, and choose the surface you will actually use.

Frequently asked questions
What is the best 18 inch pizza oven?
The Ooni Koda 2 Pro is the strongest match for an 18 inch pizza oven because it has an 18 inch rear cooking surface, propane power and room for cast iron or sheet pans. Choose a 16 inch oven if portability matters more than fitting the largest possible pizza.
Is an 18 inch pizza oven better than a 12 inch model?
An 18 inch pizza oven gives you more room for oversized pies, larger pans and multiple servings. A 12 inch model uses less space and may heat smaller portions efficiently, so the better size depends on your usual pizza diameter and how many people you serve.
Can an 18 inch pizza oven cook more than pizza?
Yes, a large cooking area can hold suitable cast iron or sheet pans when the oven supports them. The Ooni Koda 2 Pro specifically describes room for cast iron and sheet pans.
Always check the oven's fuel instructions and internal clearance before adding another type of cookware.
What fuel is best for an 18 inch pizza oven?
Propane is a practical choice for fast outdoor setup and steady heat, while wood, pellets and charcoal add fuel flexibility and smoky flavor. The Ooni Koda 2 Pro uses propane only, while the PIZZELLO supports wood, pellets and charcoal.
Do you need an 18 inch pizza pan for an 18 inch oven?
No. An 18 inch oven may use a stone as its primary cooking surface, and the usable interior can be smaller than the outside size.
The YeKuKing pan measures 17.7 inches, so check the oven's internal clearance before buying a large pan.
