Recipe Scaler
Paste an ingredient list, scale it to the servings you need, and review optional gram estimates based on the matched ingredient. Your recipes stay in this browser.

How to Use the Recipe Scaler
- 1. Choose servings or a multiplier. Enter the original and desired servings, or select a factor such as 0.5x or 2x.
- 2. Paste one ingredient per line. Common fractions, weights, volumes, and counts are scaled while notes that cannot be parsed stay visible.
- 3. Review ingredient matches. Gram estimates appear only when the ingredient is confidently matched. Change a match before using an estimate if the ingredient is wrong.
- 4. Copy, print, or save locally. Saved drafts remain on this device and the recipe text is not sent to an account or cloud service.
Tips for Scaling Recipes
Review Weight Estimates
Cups of flour, honey, and butter do not weigh the same. Gram estimates use the selected ingredient's density and are still affected by brands and measuring technique.
Adjust Leaveners Carefully
Baking powder, baking soda, and yeast may need recipe-specific adjustments in a large batch. Treat the scaled amount as a starting point rather than an automatic baking rule.
Consider Pan Size
Doubling a recipe often means using a larger pan or multiple pans. This affects depth, baking time, and heat distribution.
Test Before Big Batches
For a 4x batch or larger, test a smaller version first and write down any timing or texture changes.

Common Scaling Factors
| To Scale From → To | Multiplier | Example |
|---|---|---|
| 4 → 2 servings (halve) | 0.5× | 1 cup → 1/2 cup |
| 4 → 6 servings | 1.5× | 1 cup → 1 1/2 cups |
| 4 → 8 servings (double) | 2× | 1 cup → 2 cups |
| 4 → 12 servings (triple) | 3× | 1 cup → 3 cups |
| 6 → 4 servings | 0.67× | 1 cup → 2/3 cup |
Frequently Asked Questions
To scale a recipe, divide your desired servings by the original servings to get a multiplier. Then multiply each ingredient amount by that number. Our calculator does this automatically - just enter your original and desired servings.
