The chef's caveat

Dry → Cooked

Grains absorb water when they cook. 1 cup of dry bread becomes about 3 cups cooked — the calories do not change, they just spread over more volume. Every number on this page is for cooked weight, the way you actually eat it. If your recipe reads dry, multiply by about 3.

Common questions

The stuff people actually ask.

How many calories in slice (5" x 3" x 1/2") of bread?

About 117 calories, with roughly 3.9g of protein. slice (5" x 3" x 1/2") weighs about 37g. Use the slider above for any other portion.

Do I count raw or cooked?

Whichever you weighed. Dry bread is roughly 3× as calorie-dense per gram as cooked; cooked is what is on this page. If you weigh at the pot use cooked; if you portion dry before cooking, use dry. Do not mix.

Is bread actually healthy, or is that marketing?

By the numbers on this page: "healthy" is doing work here — it is clean fuel, not a nutrient powerhouse. Fine as the base of a meal, not the meal itself.
