🍞 Recipe Scaler
Enter your recipe's original and desired servings, list the ingredients, and get every quantity recalculated at once — perfect for baking a bigger batch or a smaller one without redoing the maths.
📏 Scale Your Recipe
What is a Recipe Scaler?
It's a quick way to resize a recipe to the number of servings you actually need. Give it the original yield, the yield you want, and the ingredient list, and it multiplies every quantity by the same factor so the proportions stay true — no fractions scribbled in the margin.
Use it to stretch a family recipe for a party, shrink one down for a weeknight, or double a favourite for the freezer. Remember that only the amounts scale: pans, bake times, and leavening may need a human touch, so treat the output as your ingredient list and bake by doneness.
❓ Frequently Asked Questions
How does the recipe scaler work?
It divides your desired servings by the original servings to get a scaling factor, then multiplies every ingredient quantity by that factor. Scaling a recipe from 4 to 6 servings uses a factor of 1.5, so 2 cups of flour becomes 3 cups. Quantities are rounded to two decimals for practicality.
Do bake times and pan sizes scale too?
No — only the ingredient amounts scale linearly. A bigger batch usually needs a larger or extra pan, and bake time changes with depth and pan size rather than in step with the volume. Use the scaled quantities as your ingredient list, then judge doneness by a skewer, internal temperature, or colour instead of the original clock time.
Can I scale eggs and other whole items?
The tool gives you the exact mathematical amount — for example 1.5 eggs. In practice, beat an egg and use half by weight, or round to the nearest whole egg and nudge the liquid slightly. For leavening (baking powder, soda, yeast) large changes can behave non-linearly, so taste-test big scale-ups.
Does halving a recipe work the same way?
Yes. Going from 4 servings down to 2 uses a factor of 0.5, so every quantity is halved — 1 cup of sugar becomes half a cup. Small batches can dry out faster, so start checking a few minutes before the original time suggests.
