Calories in a Starbucks Latte: By Size and Milk

A tall (12 oz) Starbucks Caffe Latte made with 2% milk contains approximately 150 calories — a figure consistent with USDA FoodData Central data for espresso-and-steamed-milk beverages (USDA FDC #2262079).

The calorie range for a latte is wide: swap to whole milk or move up to a venti, and you can easily double that number before any syrup is added. Here is what the data shows across sizes and milk types.

Calories by Size and Milk Type

The table below uses Starbucks nutrition data (Starbucks.com nutrition page, accessed 2026) and is consistent with USDA FoodData Central values for comparable café lattes. All figures are for an unsweetened Caffe Latte with a single or double shot of espresso (as Starbucks prepares by default).

Size (oz)	Milk Type	Calories	Carbs (g)	Protein (g)	Fat (g)
Tall 12 oz	Nonfat (skim)	100	15	10	0
Tall 12 oz	2% milk	150	15	10	6
Tall 12 oz	Whole milk	180	14	10	9
Tall 12 oz	Oat milk	130	17	6	4
Tall 12 oz	Almond milk	70	8	4	3
Grande 16 oz	2% milk	190	19	13	7
Grande 16 oz	Nonfat	130	19	13	0
Grande 16 oz	Whole milk	230	18	13	11
Venti 20 oz	2% milk	250	25	17	9
Venti 20 oz	Nonfat	170	25	17	0

What the Macros Mean

The calories in a latte come almost entirely from milk. A shot of espresso contributes roughly 5 calories; everything else is the steamed milk.

• Fat varies most by milk choice. Whole milk delivers 9g fat per tall serving; skim drops it to 0g.
• Carbohydrates come from lactose (milk sugar). Non-dairy alternatives like oat milk add a few extra grams of starch-derived sugar.
• Protein is meaningful — 10g in a tall 2% latte — making lattes a reasonable protein source compared with most café beverages.

No syrup is included in these figures. Each standard pump of vanilla or caramel syrup adds approximately 20 calories and 5g of sugar.

Does It Fit Your Goals?

Weight loss: A tall 2% latte at 150 calories fits comfortably into most calorie budgets. The issue is habituation — a daily grande with one pump vanilla adds up to roughly 210 calories, or about 1,470 calories per week from a single drink. Swapping to nonfat and skipping the pump saves about 700 calories per week. Use the TDEE calculator to see how your coffee habit fits your daily target.

Blood sugar management: An unsweetened tall latte has around 15g of carbohydrates, all from lactose, which has a relatively low glycemic index (about 46). That means a moderate, gradual effect on blood glucose. Sweetened or flavored versions can push carbs above 35–45g per serving, which is a more significant glycemic load — especially if consumed on an empty stomach. Check the glycemic load calculator if you are tracking glucose response.

Building macros: The protein in a latte is real and counts toward daily protein targets, particularly useful if you are following a higher-protein diet. For a full picture of how it fits your daily targets, see our guide on how to calculate your macros.
