Calories in sandwich bread
Sandwich bread is denser than bakery bread, for a reason its plain taste hides: it carries sugar and fat that a plain loaf does not.
What a real portion weighs
The Anses table gives values per 100 grams, and 100 grams is not a portion anybody serves. Here are the same values, applied to the portions as they turn up. Weights are in grams, the unit the table is built on. For a quick conversion: 1 oz is about 28 g, and 1 lb is about 454 g.
| Portion | Weight | Energy | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|---|
| One slice · standard prepacked slice | 30 g | 84 kcal | 2.3 g | 15.1 g | 1.3 g | 0.8 g |
| Two slices · one sandwich | 60 g | 167 kcal | 4.6 g | 30.2 g | 2.6 g | 1.7 g |
| One thick slice · American or brioche style | 40 g | 112 kcal | 3.1 g | 20.2 g | 1.7 g | 1.1 g |
| The Ciqual reference · white sandwich loaf, prepacked | 100 g | 279 kcal | 7.7 g | 50.4 g | 4.4 g | 2.8 g |
These weights are usual orders of magnitude, not standardized measures: they turn a per-100-gram value into a credible portion. A kitchen scale stays more accurate than any average weight.

Sandwich bread vs whole wheat bread
Two breads, at equal weight. The one that passes for lighter is not the one people think.
| Food | Energy | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|
| Sandwich bread | 279 kcal | 7.7 g | 50.4 g | 4.4 g | 2.8 g |
| Whole wheat bread | 234 kcal | 9.5 g | 41.2 g | 1.7 g | 7.3 g |
Weight for weight, sandwich bread: 19% more energy.
What a table of values does not say
- Its density sits above whole wheat bread, while sandwich bread passes for the lighter one. The sugar and the fat in the recipe explain the gap.
- One slice weighs about 30 g. Two slices for a sandwich come to around 60 g, well under the 100 g reference.
- Whole wheat sandwich bread and crustless sandwich bread are separate lines, and taking the crust off changes the weight of a slice more than its composition.

What comes after the number
How much to eat in a day
A portion means nothing without the day that holds it. A calorie need is worked out from height, weight, age and activity level, then split into protein, carbohydrate and fat.
Calorie calculatorWhere body build sits
Body mass index, the full WHO classification, and the weight range matching a normal build for a given height.
BMI calculatorAn average weight is an estimate. A photo is not.
In Zemiam, a photo of the meal is enough to log the real portion, with the composition of this same table rather than a guessed figure.
Where the values come from
The composition comes from the Anses Ciqual table: Anses. 2025. Table de composition nutritionnelle des aliments Ciqual, published under Licence Ouverte 2.0. The per-100 g values are reproduced without being altered; the per-portion values are those same values multiplied by a weight, and that weight is not an Anses figure.
