Pan size does not scale automatically
A doubled casserole may need two pans instead of one deeper pan. Keeping the original food depth usually gives more predictable cooking.

How it works
How to scale a recipe from 4 servings to 6
Recipe scaling is ratio math: divide the new yield by the original yield, then apply that multiplier to each ingredient. The calculator handles the arithmetic while keeping the result easy to cook from.
- 01
Set both serving counts
Enter the yield written on the recipe and the yield you want to make. Going from 4 servings to 6 uses a 1.5x multiplier. - 02
Paste one ingredient per line
Put the amount first, followed by the unit and ingredient. Common fractions, mixed numbers, and notes such as "to taste" stay readable. - 03
Review, then copy or save
Check the new quantities, especially eggs and small seasonings. Copy the list for cooking or send it to an editable Pinch recipe draft.
Quick reference
Common recipe scaling amounts
The multiplier is the target servings divided by the original servings. These examples show what familiar amounts become at three useful scale factors.
| Original | Half (0.5x) | For 6 from 4 (1.5x) | Double (2x) |
|---|---|---|---|
| 1 teaspoon | 1/2 teaspoon | 1 1/2 teaspoons | 2 teaspoons |
| 1/2 cup | 1/4 cup | 3/4 cup | 1 cup |
| 1 1/2 cups | 3/4 cup | 2 1/4 cups | 3 cups |
| 2 eggs | 1 egg | 3 eggs | 4 eggs |
Practical notes
What to check after scaling a recipe
Seasoning deserves a final taste
Salt, hot spices, extracts, and leavening can become overpowering in large batches. Scale them, but add cautiously when the recipe allows it.
Cook time follows the food, not the math
A 2x ingredient multiplier does not mean 2x the oven time. Use the original temperature and begin checking doneness near the original time.
Common questions
What cooks usually ask
Planning around guests and leftovers? The serving size converter turns that head count into the target yield for you.
What formula scales a recipe?
Divide the servings you want by the recipe's original servings. Multiply every ingredient quantity by that result. For 6 servings from a 4-serving recipe, 6 / 4 = 1.5.
Can I use the scaler to halve a recipe?
Yes. Set the target to half the original yield, such as 2 servings from 4. The result uses a 0.5x multiplier and keeps common fractions in a cook-friendly format.
Should baking time change when I scale a recipe?
Sometimes, but not in direct proportion to the ingredients. Pan dimensions, batter depth, and the number of pans matter more. Keep the original temperature unless the recipe says otherwise and check early.
