The Recipe Scaler resizes any recipe up or down and shows every version side by side. Enter the ingredients from the original recipe — the quantity, unit, and name of each — and the tool builds a table with a column for each batch size you choose, so you can read off the exact amounts for whatever quantity you are making.
Tell it what your recipe makes in the “This recipe is for” box (say 2 kg): that column is marked “your recipe” and shows the ingredients exactly as you entered them, while every other column scales up or down to match its own batch size. Change the number and the whole table rescales around the new base. It is built for real cooking, too — quantities in cups, tablespoons, and teaspoons are shown as friendly fractions like ½ cup or ⅓ tsp instead of awkward decimals, while grams, millilitres, and counts stay as clean numbers. You can paste an ingredient list to fill it in instantly, add any custom batch size, switch between fractions and decimals, and download the scaled table as an image or PDF. Everything runs in your browser and your recipe is saved on your device for next time.
How to scale a recipe
- Enter each ingredient (quantity, unit, name), or click “Paste a list” and paste the whole list to fill the rows automatically.
- Set “This recipe is for” to the amount your entered recipe makes (for example 2 kg) — that column is marked “your recipe” and the others scale from it.
- Pick the batch-size columns you want to see (0.5, 1, 2, 3…), or type a custom size to add another column.
- Read the scaled table, with cook-friendly fractions for cups, tablespoons, and teaspoons (switch to decimals if you prefer).
- Copy the list, or download the table as a PNG image or a PDF.
A column for every batch size
Instead of scaling to just one size, the tool shows several at once. Each batch-size chip becomes a column, so a single table gives you the recipe at several quantities together — handy as a printable reference. The “This recipe is for” amount decides which column is your original: mark your recipe as 2 kg and the 2 kg column stays exactly as you typed it, while the 1 kg column is halved and the 3 kg column is one-and-a-half times. Change the base and the whole table rescales around it.
Need a size the chips do not cover? Type it into the “add size” box — 0.75 for three-quarters of your batch, 5 for a five-unit batch, whatever you need. Because every column is relative to your base, a recipe that serves 4 scaled to serve 6 is just a base of 4 with a 6 column shown.
Why the fractions matter
Recipes rarely use decimals. Halving ⅔ cup gives ⅓ cup, and scaling 1 tsp by 1.5 gives 1½ tsp — so the tool snaps volume measures (cups, tablespoons, teaspoons) to the nearest sensible kitchen fraction and shows it with proper symbols. Weight and volume in grams or millilitres, and plain counts, are shown as ordinary numbers. If you would rather see plain decimals everywhere, switch the display to “decimals”.
Paste, save, and export
Copying ingredients from a video description or a website is quick: click “Paste a list”, paste everything, and the tool splits each line into a quantity, unit, and name. Your recipe is saved in your browser automatically, so it is still there when you come back. When you are done, download the scaled table as a PNG image (great for sharing) or a PDF (great for printing and taking into the kitchen).
What does not scale linearly
Ingredient amounts scale linearly, but a few things do not. Cooking and baking times change with quantity but not in direct proportion; pan and tin sizes affect thickness and timing; and salt, spices, and leavening agents such as baking soda and baking powder are best adjusted by taste and judgement rather than exact multiplication — especially when scaling a recipe up a lot. Use the scaled amounts as a strong starting point and taste as you go.
Frequently Asked Questions
How do I halve or double a recipe?
Set “This recipe is for” to what your recipe makes (say 1 kg), then show the column for the amount you want — the 0.5 column halves it and the 2 column doubles it. The table displays every batch size you pick at once, so you can see half, normal, and double side by side.
Can I scale by the number of servings?
Yes — put the servings your recipe makes in “This recipe is for” (for example 4), then add the servings you want as a batch-size column (say 6). That column shows the recipe scaled to 6 servings, and the 4 column stays as you entered it.
Can I paste a whole ingredient list?
Yes. Click “Paste a list”, paste the ingredients (one per line), and the tool splits each line into a quantity, unit, and name to fill the rows automatically.
Why are some amounts shown as fractions like ½ cup?
Cups, tablespoons, and teaspoons are measured in fractions in the kitchen, so the tool snaps those to the nearest sensible fraction (⅛, ¼, ⅓, ½, ⅔, ¾, and so on). Grams, millilitres, and counts are shown as ordinary numbers. You can switch to decimals if you prefer.
Can I download or print the scaled recipe?
Yes. You can copy the scaled list as text, or download the table as a PNG image or a PDF — the PDF is handy for printing and taking into the kitchen.
Is scaling always exact?
Ingredient quantities scale exactly, but cooking time, pan size, and seasonings like salt, spices, and leavening may need adjusting by judgement — particularly when scaling a recipe up significantly. Treat the results as a reliable starting point.
