Starbucks vs Dunkin Calories: Same-Size Comparison (2026)

By NutriCalc Hub. Published October 18, 2026, updated October 21, 2026. 6 min read.

Most Starbucks vs Dunkin calories comparisons put a Starbucks Grande next to a Dunkin' Medium. That's not a fair fight: a Grande is 16 fl oz, while a Dunkin' Medium is 14 fl oz hot or 24 fl oz iced. Here, every drink is matched by fluid ounces, so you compare the same amount of coffee.

Every number comes from each brand's official US nutrition information: Starbucks (checked October 15, 2026) and Dunkin's US Nutrition Guide (updated September 21, 2026). To try your own order, use our Starbucks drink calorie calculator or the Dunkin' drink calorie calculator.

Why don't Starbucks and Dunkin' sizes match?

The two chains use different names for different amounts. A Starbucks Grande (16 fl oz) is the same size as a Dunkin' Small iced drink, not a Dunkin' Medium.

Sources: Starbucks US sizes (Short 8 fl oz, hot only; Trenta 30 fl oz on select iced drinks); Dunkin' US Nutrition Guide, 2026-09-21.

That's why size-matched Starbucks vs Dunkin' calories can look very different from name-matched ones. For more on Starbucks cup names, see Starbucks drink sizes explained.

Starbucks vs Dunkin calories: same-size comparison

At the same size, black coffee, cold brew and Americano are all under 30 calories at both chains, and lattes are within 40 calories of each other. The table below shows Starbucks vs Dunkin' calories and sugar for every drink we can match by ounces.

Sources: Starbucks US published nutrition, checked 2026-10-15; Dunkin' US Nutrition Guide, updated 2026-09-21. Starbucks lattes use its standard 2% milk; Dunkin's guide lists whole, skim, oat and almond milk, not 2%. Standard recipes; hand-made drinks can vary.

Starbucks vs Dunkin latte calories

A 20 fl oz hot latte has 250 calories at Starbucks (2% milk) and 230 at Dunkin' (whole milk). With the lightest dairy milk, it's 170 calories at Starbucks (nonfat) and 130 at Dunkin' (skim), 40 calories apart.

Starbucks lattes have more protein at this size: 16 g in a Venti 2% latte and 17 g with nonfat, compared with 12 g in a Dunkin' Large latte with whole or skim milk. Iced at 16 fl oz, it's 130 calories and 8 g protein at Starbucks vs 120 calories and 6 g protein at Dunkin'.

Starbucks vs Dunkin cold brew calories

Cold brew is where Starbucks vs Dunkin' calories match exactly: black cold brew is 5 calories at both chains, at 16 fl oz and at 24 fl oz. There is no difference until you add cream, milk or sweetener.

Once you add something, the drinks stop matching. A Dunkin' Small Cold Brew with cream has 60 calories, while a Starbucks Grande Vanilla Sweet Cream Cold Brew, which is sweetened, has 110 calories and 14 g of sugar. For the brewing difference, read cold brew vs iced coffee.

Brown sugar shaken espresso: Starbucks vs Dunkin'

Both have 1 g of protein at this size. See every version and size in our Dunkin' shaken espresso calories guide.

Is Starbucks or Dunkin' healthier?

Neither chain is healthier by default. When you compare Starbucks vs Dunkin calories at the same size, plain coffee drinks are almost the same; the milk, sweetener and size you choose matter far more than the brand.

• Black coffee and cold brew: a tie at 5 calories.

• Americano: both tiny; 25 calories at Starbucks vs 10 at Dunkin' (20 fl oz).

• Lattes: Dunkin's are 20 to 40 calories lower at matched sizes; Starbucks' have more protein.

• Brown sugar shaken espresso: same calories; Starbucks has 5 g less sugar.

If you have diabetes, are pregnant or manage a health condition, talk to your doctor or a registered dietitian about how much sugar and caffeine suit you.

How do I order lighter at Starbucks or Dunkin'?

The same few habits lower calories at both chains. They matter more than which chain you visit, which is the real lesson behind most Starbucks vs Dunkin' calories debates.

1. Start with a low-calorie base. Black coffee, cold brew and Americano are 25 calories or less at both.

2. Pick the lightest milk. Nonfat at Starbucks, skim at Dunkin'.

3. Go easy on sweetener. At Starbucks, a pump of standard syrup is about 20 calories and 5 g sugar, and sugar-free vanilla is 0. At Dunkin', flavor shots are unsweetened while swirls are sweetened.

4. Compare by ounces, not size names. A Grande is 16 fl oz; a Dunkin' Medium iced is 24 fl oz.

More easy swaps are in how to order Starbucks drinks with less sugar.

Bottom Line

Matched by cup size, Starbucks vs Dunkin' calories are close: black coffee and cold brew tie at 5, Dunkin's lattes run 20 to 40 calories lower, and the brown sugar shaken espressos tie at 120 calories with less sugar at Starbucks. Your milk, sweetener and size decide far more than the logo on the cup.
