Where the 9" tube / angel food sits among tube pans
| Pan | Holds (brim) | Batter (⅔) | Bake area | Depth |
|---|---|---|---|---|
| 9" tube / angel food (3" deep) | 12 cups | 8 cups | 55 sq in | 3″ |
| 10" tube / angel food (4" deep) | 16 cups | 10¾ cups | 68 sq in | 4″ |
Swapping a recipe into or out of this pan
These hold about the same batter but bake differently — the batter sits at a different depth (shallower runs faster, deeper slower), or a centre tube changes how heat reaches it: 3"-deep 9" round (12 cups; batter 2.1″ → 1.8″ deep), 10" Bundt (12 cups; batter 2.1″ → 1.6″ deep), 10" springform (12 cups; batter 2.1″ → 1.5″ deep), 10" round (11 cups; batter 2.1″ → 1.5″ deep). Treat these as a change of bake, not a straight swap.
Check the batter comes no more than about two-thirds up the new pan. 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.
