A 9x13 pan has about 117 square inches of surface area, while an 8x8 pan has 64 square inches - roughly 55% of the area. To convert, multiply your ingredients by about 0.55 (a little over half). Use the Pan Size Converter above: select your original pan, choose the new pan, and click Apply to scale your ingredients automatically. The batter will be deeper in the smaller pan, so increase baking time by 5-10 minutes and check for doneness with a toothpick.

When you use a larger pan, the batter spreads thinner and bakes faster - check 5-10 minutes earlier. A smaller or deeper pan holds more batter per inch and needs more time, sometimes 10-15 minutes extra. Enter your original temperature and bake time in the Bake Time & Temperature section, and the tool will suggest adjusted values based on your scaling factor. As a rule of thumb: if the area doubles, check 25% earlier. If it halves, add 25% more time. Always use the toothpick test for the final check!

Set the multiplier to 0.5 using the quick buttons, or type 0.5 in the custom multiplier field. Every ingredient amount will be scaled down by half and converted to clean cooking fractions. If your recipe serves 6 and you want 3, switch to Servings mode and set your desired servings to 3 - the multiplier updates on its own. For tricky ingredients like eggs (e.g., halving 3 eggs), beat 2 eggs together and use 3 tablespoons of the mixture (about 1.5 eggs).

Yes! The servings scaler works for any recipe. However, pan conversions are specifically designed for baking where pan surface area affects bake time and texture. For stovetop recipes like soups, sauces, or casseroles, just use the Servings mode - no pan conversion needed. The ingredient scaler handles all types of measurements including volume (cups, tablespoons), weight (ounces, grams), and counts (eggs, apples).

Great question! If a recipe calls for 3 eggs and you are halving it, you need 1.5 eggs. Beat 2 eggs together, then use 3 tablespoons of the mixture (about half). Or, use 1 large egg plus 2 tablespoons of beaten egg. Our ingredient scaler handles this automatically - just type "3 large eggs" and set your multiplier to 0.5, and it will show you the exact scaled amount with helpful notes.
