Recipe Scaler
Scale a recipe to any number of servings: multiply all ingredients by your factor and read the new amounts in one table.
About this tool
Enter original and target servings plus any ingredient amount, and get the scale factor and converted amount — the fastest way to double, halve or rework a recipe.
Half-finishing meals or cooking for eight from a four-person recipe should not require arithmetic mid-dinner. One table of multipliers keeps every pot scaled consistently, including the sneaky baking-powder math.
FAQ
How do I scale a recipe?
Multiply every ingredient by (target servings / original servings). This calculator does the arithmetic for one ingredient at a time.
What breaks at large scale?
Pan space and bake geometry: doubling a cake recipe may need two pans. Seasonings follow taste above raw multipliers.
Can I reverse it?
Yes — set original below target to scale down: 6 servings to 3 is a 0.5x factor.
