Where the 10" round sits among round pans
| Pan | Holds (brim) | Batter (⅔) | Bake area | Depth |
|---|---|---|---|---|
| 6" round (2" deep) | 4 cups | 2¾ cups | 28 sq in | 2″ |
| 8" round (2" deep) | 6 cups | 4 cups | 50 sq in | 2″ |
| 9" round (2" deep) | 8 cups | 5¼ cups | 64 sq in | 2″ |
| 10" round (2" deep) | 10½ cups | 7 cups | 79 sq in | 2″ |
| 8" round (3" deep) | 10 cups | 6¾ cups | 50 sq in | 3″ |
| 9" round (3" deep) | 12 cups | 8 cups | 64 sq in | 3″ |
Swapping a recipe into or out of this pan
By capacity, the honest substitutes are 3"-deep 8" round (10 cups), 9" square (10 cups), 10×15" jelly roll (10 cups), 9" springform (10 cups) — each within 10% of the 10" round's 10½ cups, close enough that a recipe usually moves over without rescaling. Check the batter comes no more than about two-thirds up the new pan, and remember what still changes is batter depth: depth sets bake time — shallower runs faster, deeper runs slower. The cake pan converter works out the exact time and temperature shift for any pair.
Filling guidance: two-thirds is the working rule for butter and oil cakes. Batters with big oven spring — angel food, chiffon, some sponges — want more headroom, and dense batters (brownies, blondies) tolerate fuller pans because they barely rise.
