| Compact single-deck oven | About 18 × 18 in (46 × 46 cm) | 1 | About 150–500°F (65–260°C) | Roughly 3–6 kW | Small bakeries, cafés, and low-volume artisan bread or pastry production. | Small footprint and lower capacity; check whether the deck accommodates the bakery’s trays or pans. |
| Half-sheet single-deck oven | About 18 × 24 in (46 × 61 cm) | 1 | About 150–500°F (65–260°C) | Roughly 4–8 kW | Small-to-medium bakeries baking cookies, rolls, and tray-based pastries. | Can suit one 13 × 18 in half-sheet pan, subject to usable interior space and loading clearance. |
| Long single-deck oven | About 18 × 36 in (46 × 91 cm) | 1 | About 150–500°F (65–260°C) | Roughly 5–10 kW | Businesses needing a longer hearth for baguettes, batards, or multiple smaller items. | Verify the clear deck area and door opening; long loaves need usable loading and unloading space. |
| Standard two-deck oven | About 24 × 36 in per deck (61 × 91 cm) | 2 | About 150–500°F (65–260°C) | Roughly 10–20 kW total | Medium-volume bakeries producing bread and pastries at different temperatures or in separate batches. | Independent controls are useful when each deck needs a different temperature; check electrical supply and ventilation. |
| Three-deck production oven | About 24 × 36 in per deck (61 × 91 cm) | 3 | About 150–500°F (65–260°C) | Roughly 15–30 kW total | Higher-volume bakeries with steady daily production and several products in rotation. | Offers more baking capacity in one footprint; confirm available amperage, phase, and space for servicing. |
| Stone-hearth deck oven | Commonly about 18 × 24 to 24 × 36 in per deck (46 × 61 to 61 × 91 cm) | 1–3 | About 150–500°F (65–260°C) | Varies by size; commonly about 4–10 kW per deck | Artisan loaves and hearth-style products where direct contact with a heated baking surface is desired. | Stone or refractory hearths store heat; allow for warm-up time and follow the maker’s cleaning and maintenance instructions. |
| Steam-injection deck oven | Commonly about 18 × 24 to 24 × 36 in per deck (46 × 61 to 61 × 91 cm) | 1–3 | About 150–500°F (65–260°C) | Varies by size and steam system; commonly about 5–10 kW per deck | Bakeries making crusty bread that benefits from steam during the early part of baking. | Check water connection, drainage, steam controls, and cleaning requirements; steam features vary by model. |
