Frequently asked questions
How is the factor worked out?
From the area of the pan bases, assuming the batter fills both pans to the same depth. A 9-inch round holds about 1.27 times as much as an 8-inch round.
Do I need to change the baking time?
A larger, same-depth pan bakes in about the same time; a deeper fill takes longer at a slightly lower temperature. Start checking 5–10 minutes early with a skewer.
