Recipe Halver

Cut any recipe in half instantly — every ingredient divided by two, awkward fractions included. Free, no sign-up.

A recipe halver divides every ingredient quantity in a recipe by two, so a dish that serves 8 serves 4 without you doing fraction math at the counter. Paste your ingredients below, tap ½×, and the calculator rewrites each amount — turning ¾ cup into 6 tablespoons and 1 tablespoon into 1½ teaspoons.

Halve Your Recipe

Paste your ingredients, tap the ½×button, and every quantity is cut in half. Whether you searched for a half recipe calculator or a "recipe halfer", this is it — and it can double or triple too.

How do you halve a recipe?

Divide every ingredient by 2 and leave the method alone. That's the whole trick — the annoying part is the arithmetic, because recipes are written in cups, tablespoons, and whole eggs that don't split cleanly. Here's a pancake recipe for 4, cut down to 2:

Most rows are easy. The ones that trip people up — 3 tablespoons, odd fractions of a cup, a single egg — are exactly what the calculator above and the chart below are for.

Halving Chart: the Awkward Amounts

The measurements that don't split neatly, worked out once so you never have to again. (US cups: 1 cup = 16 tablespoons = 48 teaspoons.)

Three Things That Don't Halve Neatly

• Eggs. One egg is the classic half-batch problem. Beat it until the yolk and white are blended, then measure out half — about 2 tablespoons, or 25 grams on a scale. For forgiving recipes (pancakes, muffins, meatballs) just use the whole egg and hold back a splash of the other liquid.
• Bake times. Half the batter does not mean half the time. Keep the oven temperature the same, pick a smaller pan so the batter sits at a similar depth (a 9×13 recipe halved fits an 8×8), and start checking at about two-thirds of the original time.
• Salt, spices, and leavening. These punch above their weight in small batches, and half of ¼ teaspoon is fiddly to measure. Divide baking soda and baking powder exactly — baking is chemistry — but for salt and strong spices, go slightly under, taste, and adjust.

Convert Units While You Halve

Half of ⅓ cup is easier in grams. Cups to grams, ounces to grams, °F to °C, tablespoons to ml, and more.

Scaling in the Other Direction (and Beyond)

Halving is one job of the wider recipe scaler. If you're cooking for a crowd instead of cutting down, the recipe doubler goes the other way, and the recipe multiplier handles 3×, 5×, or any custom batch size. Working from a European recipe or a kitchen scale? The recipe-to-metric converter switches cups to grams and millilitres.

To halve a recipe straight from a website — no copy-pasting ingredients — use the Drizzlelemons recipe converter: paste any recipe URL and it extracts a clean, ad-free recipe you can halve, convert, and save. Then follow it hands-free at the stove with Cook Mode. No ads, no popups, no life stories.
