Equivalent pan

Mathematical

Find a pan that keeps the batter surface roughly constant when you scale a recipe.

Equivalent sizeØ 33.9 cm

This keeps the pan area proportional to the recipe (same batter depth). It does not guarantee identical baking: always check doneness by sight.

Not covered by this calculation

  • Very deep pans: with a different batter depth the area comparison no longer holds.
  • Bundt/ring pans: usable capacity differs a lot from nominal size — no reliable equivalent.
  • Tube pans (central chimney): the geometry is not comparable to plain pans.
  • Irregular shapes: measure the pan's capacity with water instead.

How to scale without ruining the dish

Scaling a recipe isn’t just math—check cook times, pan size, and ingredient density to keep texture and doneness right.

Quick tips

  • For pans, surface area matters more than depth for bake time.
  • Chemical leaveners scale in proportion—the variable is the pan: when you double a delicate batter (pancakes, muffins), use separate pans instead of one overfilled tin and start checking doneness early.
  • Keep salt proportional but taste at the end—especially for sauces.
  • For long braises/stews, add ~10% liquid when doubling.
Quick example Cake for 8 in a 20 cm pan? For 12 servings, use a 23 cm pan and start checking doneness 5 minutes earlier.

Scaling multiplies quantities linearly; leavening, seasoning and cook times may need manual adjustment. Ingredient matching uses ChefSolver's ingredient index. Full notes in the tool on ChefSolver.
