How to size a pizza oven
Measure the cutout, not the existing unit
Indoor countertop pizza ovens: 16″×16″×10″ compact, up to 22″×18″×14″ for full-size. Need 3″ clearance behind and 6″ above for ventilation. Outdoor portable wood/gas ovens range from 16″ (one 12″ pizza) to 24″+ (multiple pizzas at once). Built-in ovens follow standard masonry rough-in dimensions specific to model.
Plumbing and electrical reduce usable depth
Supply lines, drains, vent ducts, and electrical run in the back 3–4″ of most cabinets. The catalog dimension assumes those connections sit flush against the back wall. If a previous installation routed lines along the side, the new unit may not fit even though the cutout looks correct. Pull the existing unit before ordering to confirm.
Standard vs. compact sizing
Compact / countertop: one 10–12″ pizza at a time, electric typically. Mid-size portable: one 13″ pizza, gas or wood. Full-size built-in: 16″+ pizzas, often 2 at a time, requires masonry hearth and chimney.
Common mistakes
- Assuming all "standard" units in the same category are interchangeable. Cabinet height varies by 1–2″ between brands.
- Adding new flooring under the existing unit; the new layer traps the unit under the counter.
- Ignoring door swing or pull-out clearance in front of the unit.
- Mixing US and EU standards. EU appliances are sized in centimetres (60 cm ≈ 23.6″), not 24″.
