Common Questions About Loaf Pan Sizing
How do I know when the loaf is done?
Insert a toothpick or skewer into the center. It should come out clean or with just a few moist crumbs. For bread, internal temp should be 190-200°F. Don't rely on top browning alone - loaf pans brown tops fast but centers take longer.
What if my loaf top browns too fast?
Tent loosely with aluminum foil after 30-40 minutes. This is common with 9×5 pans because of the taller loaf. The foil allows continued baking without over-browning the top.
Can I halve a 9×5 recipe to fit 8×4?
Almost! Divide by 1.69 (or multiply by 0.59). Realistically, you can use about 60% of the recipe. Check 10-15 minutes earlier than the 9×5 time.
Does pan material matter?
Yes! Glass loaf pans need 25°F lower temp. Dark non-stick pans also benefit from -25°F. Light aluminum is standard and needs no adjustment.
