The 6" round pan in centimeters, and pans of about the same size
Measured across the top, the 6" round pan is 15.2 cm across, with a base of 182 cm².
No other common pan, or pair of pans, is within 10 % of its area, so scale the recipe with the factors in the table above.
Measure a pan across the top, from inside edge to inside edge, not across the bottom or the outside: that is the size recipes and labels give. Pans with sloped sides are smaller at the bottom than the size on the label.
Factors keep the batter as deep as in the 6" round pan. Below 1 means make less; above 1, more.
Frequently asked questions
How big is the 6" round pan?
Its base is 28.3 sq in (182 cm²).
How do I convert a recipe from the 6" round pan to the 9x13" pan?
Multiply the recipe by 4.14 (about 4 1/4 ×) so the batter stays as deep. The 9x13" pan is 117 sq in.
Does the baking time change?
If the batter is deeper or shallower than the recipe’s, yes: shallower bakes faster, deeper slower. Start checking early and use the recipe’s doneness test.
