Half Recipe Calculator
Cut any recipe in half in seconds — without the awkward fraction math.
Paste the recipe, set the original servings, and enter half. The tool halves every ingredient and converts odd amounts (3 eggs, 1/3 cup, 1.5 tsp) into measurable ones.

How to half a recipe
- Paste the recipe into the box above (the ingredient list is enough).
- Set the original servings (e.g. "4").
- Enter half (e.g. "2") as the target.
- Click Scale My Recipe — every quantity is halved instantly.
The tricky parts (handled for you)
- Eggs: half of 3 eggs ≈ beat 1 egg and use about 3 tablespoons, or use 1 whole egg for sturdy bakes.
- Fractions: half of 1/3 cup = 2 tbsp + 2 tsp; half of 3/4 cup = 6 tbsp.
- Odd spoons: half of 1.5 tsp = 3/4 tsp.
What about cooking time and pans?
Ingredients halve cleanly; time and equipment don't. A halved batch often cooks a little faster, so check early — and for baking, use a smaller pan to keep the same depth. Use the scaled amounts as your guide and your own judgment for time.

FAQ
Q: How do I half a recipe?
Divide every ingredient quantity by two. Paste the recipe above, set the original servings, and enter half that number — the calculator rewrites each amount for you, including the awkward ones.
Q: How do I halve 3 eggs or 1/3 cup?
For eggs, beat one and use half (about 2 tablespoons per egg). For 1/3 cup, half is about 2 tablespoons + 2 teaspoons. The calculator converts fractional and odd amounts into measurable ones automatically.
Q: Do cooking times change when I half a recipe?
Usually only a little. The ingredient amounts halve, but a smaller batch in the same pan may cook slightly faster — start checking 5–10 minutes early. Baking in a smaller pan keeps the depth and timing closer to the original.
