Recipe scaler saves you from mental arithmetic when you need to adjust ingredient quantities for a different number of portions. Instead of recalculating every single line, simply enter the original servings (what your recipe yields) and the target servings (what you need). Then click “Scale all”. Every ingredient amount updates proportionally: if you double the servings, every flour gram, egg, or teaspoon is doubled. This preserves the original ratios — the secret behind consistent results whether you’re baking for two or twenty.
This scale recipe calculator is built for flexibility. You can edit any ingredient’s name, unit, or quantity at any time. Use the ✕ button to remove ingredients you don’t need, or “+ Add ingredient” to extend the list. The tool automatically recalculates the scaling factor based on your servings. For instance, if original is 4 and target is 10, the factor is 2.5 — all ingredient amounts are multiplied by 2.5. The tool works for any consistent unit: grams, cups, ml, pieces, or spoons. Just keep the unit label consistent per row.
Pro tip: For dry ingredients, we recommend weighing in grams for precision. For liquids, milliliters work well. You can also use this scaler to adjust ingredient quantities for batch cooking, event catering, or testing smaller batches. The ratio logic stays the same. Bookmark this tool for your weekly meal prep — it’s like having a sous-chef for math.
