Dunkin’ Donuts Cup Sizes Guide (2025): Hot, Iced & Espresso Breakdown

Last updated on July 30th, 2025 at 01:07 am

Dunkin’ Donuts cup sizes can be surprisingly confusing — especially if you’re trying to track your caffeine intake or customize the perfect drink.

With four hot sizes and three iced options, knowing what you’re actually getting in each cup matters more than you think.

Order a large thinking it’s 20 oz, only to get 24? That small detail can throw off your daily coffee game — or your energy levels.

This guide breaks it all down for you: hot vs. iced, ounces per size, how Dunkin’ compares to Starbucks, and what size fits your drink best.

Let’s make sure your next order is spot-on.

Dunkin’ Hot Drink Cup Sizes (Small–XL)

If you’ve ever stood at the counter wondering what exactly you’re getting in that Dunkin’ cup — you’re not alone.

Hot drink sizes at Dunkin’ range from Small to Extra-Large. But the actual ounces, espresso shot counts, and drink types each size supports? Most people have no idea.

Let’s break it down by size so you can order with confidence — and get exactly the caffeine kick you’re looking for.

Small (10 oz)

The Small cup at Dunkin’ holds 10 ounces — and it’s only available for hot drinks.

If you’re ordering a latte or cappuccino, expect 1 shot of espresso. For stronger drinks like an Americano or macchiato, you’ll usually get 2 shots.

It’s the go-to size for lighter coffee drinkers or anyone keeping caffeine in check.

Seen on Reddit and Pinterest: people often underestimate how much punch this tiny cup can pack.

Medium (14 oz)

The Medium cup gives you 14 ounces of hot coffee or espresso-based drinks — and it’s the most common choice.

For a cappuccino or latte, you’ll typically get around 1.5 shots. An Americano or macchiato will come with 3 shots of espresso.

It strikes a perfect balance between size, strength, and value.

According to The Coconut Mama, this is Dunkin’s most versatile size for hot espresso drinks.

Large (20 oz)

Dunkin’s Large hot cup holds 20 ounces — making it the largest standard size for most espresso and coffee drinks.

You’ll get 2 shots in a latte or cappuccino, 3 in a macchiato, and up to 4 shots in an Americano.

Need serious fuel? This is your size.

This size also crosses over into some iced drinks, but the ounce count shifts. More on that in the iced section.

Extra-Large (24 oz)

This cup is exclusive to hot beverages like brewed coffee and tea — you won’t see it used for lattes by default.

It holds a full 24 ounces and, in some cases, you can request a custom latte with around 2.5 shots of espresso.

If you’re in it for volume, especially for a long commute or a caffeine marathon, this is the cup to order.

Coffee Geek and The Coconut Mama both highlight the XL as a favorite among heavy coffee drinkers. On Pinterest, it’s a trending size for DIY latte hacks.

Bottom line:

Each Dunkin’ cup size isn’t just about volume — it directly impacts how much espresso or caffeine you’re getting. Knowing what’s in your cup means better drink choices, better energy control, and no more surprises.

Dunkin’ Iced Drink Cup Sizes (S–L)

When you order an iced drink at Dunkin’, the cup sizes are not the same as the hot ones. In fact, iced sizes run larger across the board — and that’s something you need to know before customizing your drink.

Whether you’re trying to boost your caffeine, cut back on sugar, or just avoid a watered-down iced coffee, here’s how each size breaks down.

Small Iced (16 oz)

This is the entry-level size for Dunkin’s iced beverages.

• Holds 16 ounces — same as a Starbucks Grande iced.

• Works great for iced coffee, iced tea, or a smaller iced latte with 1–2 espresso shots.

• Best for light drinkers or those watching caffeine or sugar intake.

Note: You can’t order a hot drink in this size — it’s iced only.

Medium Iced (24 oz)

The medium iced cup is Dunkin’s most popular size for cold drinks — and for good reason.

• Packs 24 ounces of liquid, making it larger than most competitors’ mediums.

• Perfect for iced lattes, cold brews, or refreshers with enough room for ice and bold flavor.

• Expect 2 shots in a standard iced latte; customization available.

As seen on Cozy Corner Charm and Coffee Geek, this size balances caffeine strength and refreshment.

Large Iced (32 oz)

This is Dunkin’s largest iced drink size — and it’s massive.

• Holds a full 32 ounces, making it one of the largest iced coffee cups in the fast-food game.

• Ideal for extra hot days, long drives, or anyone needing serious caffeine.

• Typically comes with 3–4 espresso shots in lattes or macchiatos, but you can customize up or down.

According to Facebook groups and Dunkin’ fans, this size is a fan favorite for cold brew with less ice, more coffee.

Quick Note:

Dunkin’ iced sizes are larger than hot cup sizes:

• Small iced (16 oz) = larger than small hot (10 oz)

• Large iced (32 oz) = larger than extra-large hot (24 oz)

This matters when you’re trying to gauge caffeine strength, sweetness level, or how much space ice is taking up.

Dunkin’ Cup Size Comparison Table

To make your choice even easier, here’s a quick breakdown of hot vs iced cup sizes — and how many espresso shots you typically get.

Cup Size	Hot Drinks (Ounces)	Iced Drinks (Ounces)	Espresso Shots (Hot)
Small	10 oz	16 oz	1 (latte/cappuccino), 2 (americano/macchiato)
Medium	14 oz	24 oz	1.5 (latte/cappuccino), 3 (americano/macchiato)
Large	20 oz	32 oz	2 (latte/cappuccino), 4 (americano/macchiato)
Extra-Large	24 oz	—	~2.5 (custom drinks only)

Dunkin’ vs. Starbucks (and Other Chains)

Choosing between Dunkin’ and Starbucks? It’s not just about brand — it’s about how much drink you actually get, and how much caffeine it delivers.

If you’re aiming for more value, stronger coffee, or less dilution, this section gives you the clarity you need.

Volume Comparison: Dunkin’ vs Starbucks Cup Sizes

Let’s start with the numbers — because size matters when you’re paying for coffee.

• A Dunkin’ Medium hot drink gives you 14 oz, while Starbucks Tall gives you just 12 oz.

• Dunkin’s Large Iced offers 32 oz, outperforming even Starbucks’ Trenta (30 oz) in sheer volume.

According to The Sun and The Coconut Mama, Dunkin’ consistently serves larger drinks for a lower price.

Caffeine Delivery vs. Ice Ratio

Bigger doesn’t always mean stronger — but here’s where Dunkin’ shines again.

In a BuzzFeed test, iced drinks from Dunkin’ were found to be 92% actual coffee and only 8% ice. Compare that to competitors like Starbucks, where ice filled 25–30% of the cup.

That means:

• More liquid = more caffeine per sip.

• Less ice = less dilution.

• Better value with every order.

Reddit threads and SELF Magazine confirm: customers regularly notice how much stronger Dunkin’s iced drinks taste — because they actually get more coffee.

Frequently Asked Questions 

These are the top questions people ask about Dunkin’ Donuts cup sizes — and the answers will help you order with precision and confidence.

What’s the biggest size at Dunkin’?

The Extra-Large is Dunkin’s biggest hot cup, holding 24 oz.

For iced drinks, the Large is the biggest, with 32 oz of cold coffee, tea, or espresso.

Can I get iced drinks in an XL cup?

No — Extra-Large cups are for hot drinks only. You won’t find iced lattes or cold brews served in XL.

Want more iced drink volume? Go for a Large iced (32 oz) and ask for less ice to get more liquid.

Have Dunkin’ cup sizes changed over time?

Not significantly.

Reddit threads and longtime fans confirm that Dunkin’s sizing has stayed relatively consistent, though there may be regional packaging differences.

How can I customize espresso shots per size?

Easy — just ask.

You can add or remove espresso shots in any espresso-based drink. For example:

• Order a Medium Latte with 2 shots instead of 1.5

• Boost your Large Iced Macchiato to 4 shots for stronger flavor

• Ask for a quad shot if you want serious caffeine

The Coconut Mama and Coffee Geek recommend customizing for both strength and taste.

Why are iced sizes larger than hot sizes?

Because of the ice volume.

Iced drinks use a lot of ice to stay cold — so Dunkin’ offsets this by increasing the total cup size.

That’s why a Medium hot cup is 14 oz, but a Medium iced is 24 oz. You still get a similar amount of liquid after ice.
