Starbucks cup sizes in mL: Short 237, Tall 355, Grande 473, Venti hot 591, Venti cold 710, Trenta 887 (U.S. menu sizes).
Here’s the short, practical answer people look for when they search “how many ml is the Starbucks cup?” Every standard U.S. Starbucks size is defined in fluid ounces on the menu. Converting those ounces to milliliters gives you a clear number for meal-tracking, bottle filling, or recipe swaps. Below, you’ll get a clean table for every cup size, a quick conversion explainer, and real drink examples that show which items reach 20, 24, or 30 fl oz on the actual menu pages.

|---|---|---|
| Demi (Espresso Cup) | 3 | ~89 |
| Short (Hot) | 8 | ~237 |

| Trenta (Cold Only) | 30 | ~887 |
How Many ML Is The Starbucks Cup? Context That Clears Confusion
Starbucks lists sizes in U.S. fluid ounces on each drink page. That’s why you’ll see hot lattes with a 20-ounce ceiling (Venti hot) and iced versions that stretch to 24 ounces (Venti cold). Some cold drinks add a larger 30-ounce option (Trenta). When you want the ml figure, multiply the ounce count by 29.57 to get a close metric equivalent.
Where The Ounce Numbers Come From
Hot classics such as the Caffè Latte show 8, 12, 16, and 20 fl oz options. Iced counterparts such as the Iced Caffè Latte list 12, 16, and 24 fl oz. Cold menu items like Cold Brew and the Pink Drink offer Trenta at 30 fl oz in many U.S. stores.
Why Hot And Cold Ventis Don’t Match
“Venti” is 20 ounces on hot items but 24 ounces on iced ones. The extra room fits ice and dilution. If you’re tallying calories or caffeine by mL, use the iced figure (710 mL) for cold Venti drinks and 591 mL for hot Venti drinks.
Ounces To Milliliters: The Simple Conversion
One U.S. fluid ounce is about 29.57 milliliters. That’s the standard conversion used by measurement authorities. If you prefer a printed card, NIST lists the same figure on its Metric Conversion Card. Multiply ounces by 29.57 to get mL; round to whole numbers for everyday use.
Common Starbucks Size Conversions (Explained)
- 8 fl oz × 29.57 ≈ 237 mL — that’s a Short hot cup.
- 12 fl oz × 29.57 ≈ 355 mL — Tall.
- 16 fl oz × 29.57 ≈ 473 mL — Grande.
- 20 fl oz × 29.57 ≈ 591 mL — Venti hot.
- 24 fl oz × 29.57 ≈ 710 mL — Venti cold.
- 30 fl oz × 29.57 ≈ 887 mL — Trenta cold.
Why Your Cup Might Look Different
Reusable and merchandise cups come in a variety of sizes (often 12, 16, or 24 oz). Those aren’t “menu sizes,” but you’ll see the ounce labels on product pages. The U.K. shop, for instance, lists items like a “Reusable Holiday Cold Cup 24oz” and a “Black Espresso Cup 3oz,” which map to about 710 mL and 89 mL. That’s handy if you’re buying a cup and want metric capacity right away.
Choosing The Right Size For Your Drink
Think about ice, milk, and shot count. Iced lattes and refreshers feel smaller once the ice melts, so many people move from Grande (473 mL) to Venti cold (710 mL) when they want a longer sip. Hot drinks hold their full liquid volume, so Grande (473 mL) or Venti hot (591 mL) usually hits the mark without extras.
When Trenta Makes Sense
Trenta (887 mL) shows up on select cold items such as cold brew and refreshers. It’s built for long errands, warm days, and heavy hydration. If you count caffeine, check the drink’s nutrition page and plan around the larger size.
Milk, Foam, And “Room” Change Perceived Volume
Two Grande cups both equal ~473 mL of total capacity, yet they can feel different: a cappuccino’s airy foam displaces liquid, while a latte is milk-forward. Asking for “room” in a brewed coffee leaves headspace that reduces pour volume a little. The cup size doesn’t change, but what’s inside does.
The Menu Proof: Drinks And Their Max Sizes
These real items show where each drink tops out. You can tap through to the menu pages to confirm the ounce listing, then use the mL column for a quick metric read.
| Drink (Menu Link) | Max U.S. fl oz | Max mL |
|---|---|---|
| Caffè Latte (Hot) | 20 (Venti hot) | ~591 |
| Iced Caffè Latte | 24 (Venti cold) | ~710 |
| Cold Brew | 30 (Trenta) | ~887 |
| Pink Drink | 30 (Trenta) | ~887 |
| Cappuccino (Hot) | 20 (Venti hot) | ~591 |
| Iced Caramel Macchiato | 24 (Venti cold) | ~710 |
| Iced Caffè Americano | 24 (Venti cold) | ~710 |
How To Convert Any Starbucks Size To ML Yourself
Step-By-Step
- Open the drink’s menu page in the Starbucks app or website to see its ounce options.
- Pick the number you ordered (12, 16, 20, 24, or 30).
- Multiply by 29.57 to get mL. Round to the nearest 5–10 mL for everyday tracking.
Why Use 29.57?
That’s the U.S. fluid ounce to milliliter factor referenced by measurement standards. You’ll also see it presented on NIST’s printable Metric Conversion Card. If you’re in regions that label drinks directly in mL, the menu will already show the metric figure.
Extra Notes People Ask About
Does Every Store Carry Trenta?
Trenta is for select cold drinks and can vary by location. The quickest check is to pick your store in the Starbucks app; the size options update per item. If you don’t see 30 fl oz listed for a drink, it isn’t offered there.
Why Do Some Blogs Say 31 Oz?
You’ll see 30 or 31 oz mentioned around the web. The Starbucks U.S. menu lists Trenta as 30 fl oz on current cold items. Using that official number gives ~887 mL.
What About The Tiny Espresso Cup?
The petite ceramic espresso “demi” is a 3-oz merchandise cup (about 89 mL). You’ll find it on Starbucks retail pages alongside mugs, hot cups, and cold cups. It’s not a separate menu size for lattes; it’s the classic espresso vessel.
How Many ML Is The Starbucks Cup? Final Takeaway You Can Use Today
