How Many Calories in a Flat White?

Quick answer

A flat white has no single calorie count: it depends on the cup size and milk. Pret A Manger lists its US flat white at 70 calories (made with skim milk) and another version at 110 calories, per serving. USDA data for a latte with whole milk works out to about 103 calories for 8 fl oz (our calculation).

Calories in a flat white by brand

Pret A Manger publishes two US flat white entries. One lists 70 calories, 10 g carbohydrate, 9 g sugars, 6 g protein and 0 g fat per serving. The other lists 110 calories, 14 g carbohydrate, 13 g sugars, 9 g protein and 0 g fat per serving. Pret does not state the serving size on either page, and the 70-calorie entry only fits a skim-milk drink.

Is there a USDA figure for a flat white?

We found no USDA FoodData Central entry called flat white. The closest entry is a latte, which is also espresso with steamed milk. Per 100 g, USDA lists a latte at 43 kcal, 1.61 g fat, 4.35 g carbohydrate and 2.81 g protein, and a nonfat latte at 30 kcal.

Latte (USDA) Per 100 g Per 8 fl oz (240 g), our calculation
Latte, standard 43 kcal about 103 kcal
Latte, nonfat 30 kcal about 72 kcal

How many calories in a skinny flat white?

A skinny flat white is usually made with skim (nonfat) milk. The 70-calorie Pret entry and the 72-calorie nonfat latte estimate are close, so about 70 calories is a fair guide for a small cup.

Flat white vs latte calories

Both are espresso and steamed milk, so the milk and cup size decide the calories. We found no official source that compares the two drinks directly, so we cannot say one has fewer calories. Check the nutrition panel of the cafe you use.
