x0.55 multiplier
Recipe scaling
scale ingredients down × 0.55
Area ratio: 64 / 117 sq in
Bake time
Decrease bake time by 10–20%
Depth & temp
Batter will be deeper - reduce oven temp by 10-15 °C (25 °F) and check early.
Multiplier is based on pan area. For recipes measured by volume (cups, mL), multiply each ingredient by ×0.55. Always check doneness with a toothpick - oven variations apply.

What Matters for This Conversion
- - Ingredient multiplier is about 0.55 (55%).
- - Batter depth increases, so center doneness becomes the limiting factor.
- - Reduce oven temperature by about 10-15°C (25°F) and check early.
FAQ
What is 9x13 to 8x8 as a multiplier?
Use about 0.55x. For example, 200 g flour becomes about 110 g.
Do I need to change oven temperature?
Usually yes. Lower by roughly 10-15°C (25°F) because the batter sits deeper.
Will bake time be shorter or longer?
Often longer in the center, even though total batter is reduced.
Can I still fill the 8x8 pan to the top?
No. Keep headroom to avoid overflow and uneven rise.
