Calories in a margherita pizza
The margherita is the least loaded of the pizzas, so the least dense. It is still a whole meal, and the portion decides the total.
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 |
|---|---|---|---|---|---|---|
| A whole pizza · single-serving pizzeria size | 400 g | 896 kcal | 34.8 g | 118.4 g | 29.6 g | 9.1 g |
| One slice · a quarter of a pizza | 100 g | 224 kcal | 8.7 g | 29.6 g | 7.4 g | 2.3 g |
| A frozen pizza · single-serving retail size | 350 g | 784 kcal | 30.4 g | 103.6 g | 25.9 g | 7.9 g |
| The Ciqual reference · cheese or margherita pizza, prepacked | 100 g | 224 kcal | 8.7 g | 29.6 g | 7.4 g | 2.3 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.

What a table of values does not say
- A single-serving pizza weighs around 400 g. The per-100 g value therefore matches roughly one slice out of four.
- The margherita is the low reference of the category: four-cheese, bacon and kebab pizzas are clearly denser lines of the table.
- This line is a prepacked pizza. A pizzeria base, thicker or thinner, moves the result as much as the topping does.
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.

An 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.
