Pan Size Converter
Compare two pans by surface area — or by volume when you enter depths — to get a batter multiplier. Estimates and their caveats are spelled out, including when baking time and temperature need attention.

Batter adjustment
×0.79
Multiply every ingredient by 0.79 — your pan holds −21% less than the recipe's pan.
Compared by surface area: 410.4 cm² → 324.3 cm².
- Compared by surface area, which assumes a similar batter depth in both pans. Add both pan depths for a volume-based comparison.
- Baking time will change with the new pan — batter depth differs, so start checking a few minutes early.
