Pizza Oven Sizes: Portable, Electric and Built-In Dimensions
Pizza ovens are sized by the largest pizza they bake, but the number that decides where one can go is the outside footprint plus room for fuel, a peel and a prep area. Here are real dimensions for each class of oven.
A portable oven for 12-inch pizzas measures about 24 × 16 × 12 in (62 × 39 × 29 cm) and weighs about 20 lb (9 kg). A 16-inch model is about 25 × 23 × 15 in (63 × 58 × 37 cm) and 40 lb (18 kg). Built-in wood-fired ovens have cooking floors of 32 to 48 in (80 to 120 cm) across and need a base about 4 to 6 ft (1.2 to 1.8 m) wide.

Pizza oven sizes by type
Every oven class has a typical footprint. These ranges are drawn from current models; individual ovens can fall outside them, so check the spec sheet of the one you shortlist.
| Type | Max pizza | Outside size (L × W × H) | Weight |
|---|---|---|---|
| Compact gas or pellet | 12 in (30 cm) | 24-28 × 15-17 × 12-30 in 62-70 × 39-43 × 29-76 cm | 20-35 lb (9-16 kg) |
| Countertop electric | 12 in (30 cm) | about 21.5 × 17.5 × 10.5 in 55 × 44 × 26 cm | about 39 lb (18 kg) |
| Family gas | 16 in (40 cm) | 25-26 × 23-24 × 15 in 63-66 × 58-61 × 37-38 cm | 40-45 lb (18-20 kg) |
| Multi-fuel with chimney | 12-16 in | up to 33 × 20 × 33 in up to 83 × 50 × 83 cm | 26-63 lb (12-28 kg) |
| Large portable gas | 18-20 in (46-51 cm) | about 31 × 28 × 17 in 80 × 72 × 43 cm | about 95 lb (43 kg) |
| Built-in brick or refractory | Several pizzas at once | Floor 32-48 in inside; base 4-6 ft wide Floor 80-120 cm; base 1.2-1.8 m | Hundreds to over 2,000 lb |
The "max pizza" number is the pizza the maker designs for, not the floor size. A 12-inch oven's stone is slightly larger than 12 in so the pizza can be turned with a peel without touching the walls.
Dimensions of popular portable pizza ovens
Published specifications from the manufacturer's own product pages (unboxed, legs folded where relevant):
| Model | Pizza size | Dimensions | Weight | Fuel |
|---|---|---|---|---|
| Ooni Koda 12 | 12 in | 24.4 × 15.5 × 11.7 in (62 × 39 × 29 cm) | 20.2 lb (9.2 kg) | Gas |
| Ooni Koda 16 | 16 in | 25 × 23.2 × 14.7 in (63 × 58 × 37 cm) | 40.1 lb (18.2 kg) | Gas |
| Ooni Koda 2 Max | Up to 20 in | 31 × 28 × 17 in (80 × 72 × 43 cm) | 95 lb (43 kg) | Gas |
| Ooni Karu 2 Pro | 16 in | 32.4 × 19.8 × 32.4 in (82 × 50 × 82 cm) | 62.6 lb (28.4 kg) | Wood, charcoal or gas |
| Ooni Volt 2 | 12 in | 21.5 × 17.4 × 10.4 in (55 × 44 × 26 cm) | 38.8 lb (17.6 kg) | Electric, 1,600 W |
The Koda 2 Max has a 24 × 21 in (61 × 53 cm) stone, which also takes two 12-inch or three 10-inch pizzas at once. The Karu 2 Pro's height includes its chimney, and its cooking floor is 17 in wide inside with an interior height of about 5.7 in, enough for a cast iron pan or a small roast. Gozney's Roccbox is another 12-inch gas oven with an optional wood burner, and Gozney describes its larger Dome range as having room for up to two 12-inch or one 18-inch pizza.
Built-in wood-fired oven sizes
Masonry and refractory ovens are described by the inside diameter of the cooking floor. Model names often give it directly in centimeters, so an "80" or "100" oven usually has an 80 or 100 cm floor.
| Floor diameter | Floor area | 12-inch pizzas at once | Suits |
|---|---|---|---|
| 28-32 in (70-80 cm) | 4.3-5.6 sq ft | 1 | A family, small patios |
| 36 in (90 cm) | 7.1 sq ft | 2 | Regular home use and small parties |
| 40-42 in (100-105 cm) | 8.7-9.6 sq ft | 2-3 | Frequent entertaining, bread baking |
| 48 in (120 cm) | 12.6 sq ft | 3-4 | Large gatherings, light commercial use |
Capacity assumes the fire is pushed to one side or the back, taking about a third of the floor. Bigger is not automatically better: a larger oven needs more wood and a longer preheat (often 1 to 2 hours for a fully saturated masonry oven) to reach baking temperature.
Footprint, dome and door
- Outside size: the dome, insulation and render add roughly a foot to the floor diameter, so a 36-inch oven ends up about 4 ft (1.2 m) across. The stand or hearth slab extends further at the front to form a landing ledge.
- Hearth height: builders usually set the cooking floor at about 40 to 44 in (100 to 110 cm) above the ground, a little above kitchen counter height, so you can see in and work the peel without bending.
- Door: widely used Pompeii oven plans set the door height at about 63% of the inside dome height. That ratio keeps heat in the dome while letting smoke escape through the top of the opening. The door must also be wider than your largest peel.
- Weight: a built-in oven with its base can weigh well over a ton, so it needs a reinforced concrete footing rather than a deck or patio pavers.
How much space a pizza oven needs
- Start with the oven footprint. Take the length and width from the spec sheet, with the legs open.
- Add a landing and prep zone. You need somewhere to dress pizzas and to put them down when they come out. Allow at least 24 in (60 cm) of non-combustible counter beside the oven. A 16-inch oven therefore wants a surface about 48 in (122 cm) long.
- Add the fuel. A standard 20 lb propane cylinder is about 12 in (30 cm) across and 18 in (46 cm) tall and sits on the ground within reach of the hose. Wood and charcoal ovens need a dry box for fuel and a metal bin for ash.
- Leave room to work the peel. Peels have handles of 12 to 24 in or more, so you need about 3 ft (90 cm) of clear standing space in front of the opening.
- Check clearances in the manual. Outdoor pizza ovens run at up to 950°F (500°C) inside and their shells get hot. Manufacturers specify minimum distances from combustible walls and overhead structures. These ovens are for outdoor use only; do not place one under a low roof or awning unless the manual allows it.
A portable oven on a wooden or plastic table can scorch or melt it. Use a stainless steel, stone or concrete top, or the stand the maker sells for that model.
Pizza size vs oven size
An oven's rated size is the comfortable maximum. Neapolitan-style pizzas bake in 60 to 90 seconds at 430 to 480°C (about 800 to 900°F), and they must be turned once or twice so the side facing the flame does not burn. That turning needs space:
- 12-inch oven: best for pizzas of 10 to 11 in (25 to 28 cm). A full 12-inch pie fits, but turning it without catching the edge takes practice.
- 16-inch oven: handles a US large (14 in) easily and a 12-inch with room to spare. This is the size to buy if you also want to cook steaks or vegetables in a skillet.
- 20-inch and larger: two pizzas at once, or one New York-style 18-inch pie.
The pizza size guide converts diameters to area and servings, which tells you how many pizzas an hour you need for a party. For other outdoor cooking equipment, see the grill size guide and the smoker size guide, and for the table or counter to put the oven on, the outdoor furniture dimensions guide.
Frequently asked questions
What size pizza oven do I need?
Choose by the largest pizza you will bake. A 12-inch oven is enough for Neapolitan-style pizzas of 10 to 12 in for 2 to 4 people. A 16-inch oven takes US-style large pizzas and gives room to turn a 12-inch pie easily. For parties or bread baking, look at ovens with floors of 20 in or more.
What are typical pizza oven dimensions in cm?
Compact gas ovens for 12-inch pizzas are about 62 × 39 × 29 cm. Ovens for 16-inch pizzas are about 63 × 58 × 37 cm. The largest portable gas ovens reach about 80 × 72 × 43 cm, and built-in brick ovens have internal floors of 80 to 120 cm.
How big is a metal pizza oven?
Most freestanding metal (steel-bodied) outdoor pizza ovens are 24 to 33 in (60 to 85 cm) long and 15 to 28 in (40 to 72 cm) wide. Wood-fired metal models with a chimney stand about 30 in (76 cm) tall or more.
How many pizzas can a brick oven cook at once?
With the fire pushed to one side, roughly a third of the floor is taken by coals. A 36-inch (90 cm) floor bakes about two 12-inch pizzas at a time, a 42-inch floor two or three, and a 48-inch floor three or four.
How big a table do I need for a portable pizza oven?
The table must be non-combustible on top and larger than the oven's footprint, plus room to land the pizza. For a 16-inch oven about 25 × 23 in, a surface of at least 48 × 24 in (122 × 61 cm) gives the oven and a prep zone beside it.
