How many calories are in a chapati?
A medium chapati, about 15 cm (6 in) across and made from roughly 30 g of atta, is about 105 kcal.
First the terminology, because it confuses people more than the calories do. Chapati and roti describe the same bread: unleavened wholewheat dough rolled thin and cooked on a dry tawa. Which word gets used is regional rather than culinary — chapati across much of western and southern India and East Africa, roti through the north and most of the diaspora, phulka for the thinner puffed version. There is no calorie difference between them, and preparation and flour type are covered on the roti page. This page is about what actually decides your number: how big yours are, and what four come to.
Per portion
| Portion | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|
| 13 cm (5 in), thin — ~22 g atta | ~75 | 2.5 g | 15 g | 0.4 g |
| 15 cm (6 in), thin — ~30 g atta | ~105 | 3.5 g | 21 g | 0.5 g |
| 18 cm (7 in) — ~40 g atta | ~135 | 4.6 g | 28 g | 0.7 g |
| 20 cm (8 in) — ~50 g atta | ~170 | 5.8 g | 35 g | 0.9 g |
| 23 cm (9 in), thick — ~65 g atta | ~220 | 7.5 g | 45 g | 1.1 g |
| Four medium (15 cm) | ~420 | 14 g | 83 g | 2 g |
| Four large (20 cm) | ~680 | 23 g | 140 g | 3.6 g |
What changes the number
Beyond size, in rough order of effect: ghee or butter brushed on after cooking, which adds 20–45 kcal each; fat kneaded into the dough; and — much less than people expect — the flour, since atta, maida and millet flours all sit within about 5% of 340 kcal per 100 g. Packaged rotis let you skip the estimating, though the stated serving is often smaller than you would roll at home, so check what the label is counting.
Where it fits in a deficit
A cooked chapati is roughly 270–300 kcal per 100 g — medium density, comparable to bread. At about 3.5 g of protein each it is not carrying the meal; the dal or curd beside it is. What it does better than rice is portion itself: it is a countable unit, and “three” is a number you can hold in your head.
The honest note is that the stack is usually the first place a day’s total runs over, and dropping one chapati at lunch and one at dinner is about 210 kcal with no recipe changed. Weigh that against the alternatives — the oil in the sabzi is often the cheaper cut, and a measured serving of brown rice beside two chapatis rather than four lands similarly with more on the plate. None of it is a moral question; the deficit only responds to the total.
Diameter, thickness and a stack of four
A chapati is a disc, so its dough grows with the square of its diameter. A 20 cm chapati is not a third bigger than a 15 cm one — it is about 80% bigger. Thickness then multiplies that again, independently: a phulka rolled to 1.5 mm and a homestyle chapati at 3 mm hold a factor of two between them at the same width.
Put those together and “one chapati” spans roughly 75 to 220 kcal, which makes it close to useless as a logging unit. Four medium chapatis are about 420 kcal; four large ones are about 680. That 260 kcal gap sits between two people who both logged “4 chapatis” — and the larger stack on its own is about a third of many people’s daily target, before the dal, the sabzi and any rice are counted.
The fix is to weigh the flour for the batch rather than the bread. If 250 g of atta makes eight chapatis, that batch is about 850 kcal and each one about 105 — and since your rolling pin and your household’s appetites do not change much, that number holds for months. The alternative is weighing one cooked chapati: at 270–300 kcal per 100 g, a 40 g piece is roughly 110–120 kcal. Either measurement takes five minutes and replaces every guess after it.
