Iced Flat White nutrition by size
| Size | Calories | Caffeine | Fat | Carbs | Protein | Sugar |
|---|---|---|---|---|---|---|
| Tall | 110 | 130mg | 6g | 10g | 6g | 8g |
| Grande | 150 | 195mg | 8g | 13g | 8g | 11g |
| Venti | 220 | 260mg | 11g | 19g | 12g | 16g |
A Grande (16 fl oz) Starbucks Iced Flat White has 150 calories, 11 g sugar, 8 g protein and about 195 mg of caffeine. A Tall has 110 calories and a Venti 220. It has no syrup, so the calories come from whole milk, and the sugar is the milk's own.
What's in an Iced Flat White
Starbucks combines ristretto espresso shots with whole milk and ice. The recipe uses 2 / 3 / 4 shots for Tall / Grande / Venti, per Starbucks recipe data, which is why the caffeine rises at each size.
Milk and customization swaps
Swaps are shown as the direction of change against the standard recipe. Starbucks' product pages don't publish per-drink numbers for each swap, so check the Starbucks app or our calculator for an estimate of your exact order.
| Swap | Effect on calories | Notes |
|---|---|---|
| 2% milk instead of whole | Fewer calories and less fat | Whole milk is the default |
| Nonfat milk | Fewer calories and less fat | Protein stays about the same |
| Almondmilk | Generally fewer calories | Less protein |
| Add a syrup | Adds calories and sugar | Not part of the standard drink |
Milk effects show direction only. Starbucks doesn't publish per-milk nutrition for this drink, so the calculator estimates swaps.
Syrup pumps and calories
The Iced Flat White has no syrup by default. Starbucks doesn't list nutrition per pump on its product pages. The figure most sites quote is about 20 calories and 5 g of sugar for one pump of a standard syrup such as Classic or Vanilla. Treat that as an estimate (unverified), not a Starbucks number. Sugar-free vanilla syrup adds almost no calories. For pump counts across the menu, see our Starbucks syrup calories per pump guide.
Lower-calorie ways to order
- Switch from whole milk to 2% or nonfat.
- Order a Tall: 110 calories.
- Keep it unsweetened.
- A Grande hot Flat White has 220 calories, so the iced version is lighter.
