Dunkin' Cup Sizes: How to Choose the Right One for You
Quick Answer
Dunkin' offers four sizes for hot coffee (Small: 10 oz, Medium: 14 oz, Large: 20 oz, Extra Large: 24 oz) and three sizes for cold drinks (Small: 16 oz, Medium: 24 oz, Large: 32 oz). The right size depends on your caffeine needs and preference. The smaller cups work for quick energy boosts and larger sizes last through long mornings or afternoons.
Key Takeaways
- Hot drinks range from 10-24 oz; cold drinks from 16-32 oz
- Medium size (14 oz hot/24 oz cold) suits most regular coffee drinkers
- Customize with flavor shots, extra espresso, or milk alternatives
- Caffeine content increases proportionally with cup size
- Order format: size + hot/iced + drink type + customizations
My first Dunkin' run taught me a lesson I'll never forget. I ordered a "large coffee" expecting something modest, then nearly dropped the massive cup handed to me. That 20-ounce monster kept me wired until dinner! Now I know better because knowing your Dunkin' sizes is important for getting exactly the caffeine kick you need.
Dunkin' Size Basics
Dunkin' doesn't use Italian names like some coffee chains. They keep it simple with Small, Medium, Large, and Extra Large. But here's the twist. The hot and cold drinks come in completely different volumes.
For hot coffee lovers, sizes start smaller. A Small hot coffee holds just 10 fluid ounces, about the size of a standard coffee mug at home. The Medium jumps to 14 ounces, Large to 20 ounces, and Extra-Large maxes out at 24 ounces and that's three cups of home-brewed coffee in one container!
Cold drink fans get more volume across the board. According to a guide on Pinterest, the Small cold drink starts at 16 ounces, Medium holds 24 ounces, and Large contains a whopping 32 ounces of icy refreshment. Unlike hot drinks, there's no Extra-Large option for cold beverages.

Hot Coffee Sizes Explained

Small Hot Coffee (10 oz)
The Small hot coffee works best for quick caffeine fixes or trying new flavors. Its 10-ounce size delivers enough energy without overwhelming your system or your taste buds.
This size also makes an excellent choice for sampling seasonal flavors or testing out different customizations. You'll get the full Dunkin' experience without committing to a larger portion.
Medium Hot Coffee (14 oz)
The Medium hot coffee hits the sweet spot for most regular Dunkin' visitors. At 14 ounces, it provides enough coffee to fuel your morning meetings or afternoon productivity sessions.
This size allows plenty of room for adding cream, milk alternatives, or flavor shots without diluting the coffee experience. It's also comparable to what other coffee shops might call a "tall" or "Grande."
Large Hot Coffee (20 oz)
When serious caffeine becomes necessary, the Large hot coffee delivers with its 20-ounce capacity. This size powers busy professionals through demanding workdays or students through extended study sessions.
The large size gives you enough coffee to last through longer meetings or commutes. Many Dunkin' regulars consider this their go-to size for maximum productivity days.
Extra Large Hot Coffee (24 oz)
The Extra-Large hot coffee serves serious coffee enthusiasts with its 24-ounce capacity. This size works for those who need their coffee to last all morning or want to share with a friend.
Interestingly, Dunkin' took steps toward sustainability regarding these large cups. In 2018, they announced their intention to systematically eliminate polystyrene foam cups worldwide for environmental reasons by April 2020, according to their company history.
Cold Drink Sizes Breakdown

Small Cold Drink (16 oz)
The Small cold drink offers 16 ounces of refreshment and that is 60% more volume than its hot counterpart. This size works perfectly for a quick cool-down or enjoying a cold brew without excess.
The 16-ounce size fits easily in car cup holders and provides enough iced coffee to satisfy without overwhelming. It's also the most affordable option for trying Dunkin's cold drink innovations.
Medium Cold Drink (24 oz)
The Medium cold drink delivers 24 ounces of refreshment, and this is equivalent to Dunkin's Extra Large hot coffee. This popular size satisfies most cold drink fans with its substantial volume.
Many regular customers prefer this size for its balance between price and quantity. The 24-ounce cup provides enough space for extra ice without diluting the drink too quickly.
Large Cold Drink (32 oz)
The Large cold drink maxes out at 32 ounces and that's a full quart of icy refreshment! This size serves those planning to sip throughout the day or share with friends.
This generous portion ensures you won't run out quickly, even on the hottest days. According to Dunkin' cup size guides, this large size equals two of their small hot coffees in volume.
Caffeine Content By Size

Understanding caffeine content helps manage your daily intake. Here's what each hot coffee size contains:
- Small Hot Coffee: 215 mg caffeine
- Medium Hot Coffee: 302 mg caffeine
- Large Hot Coffee: 431 mg caffeine
- Extra Large Hot Coffee: 517 mg caffeine
For cold drinks:
- Small Iced Coffee: 203 mg caffeine
- Medium Iced Coffee: 295 mg caffeine
- Large Iced Coffee: 398 mg caffeine
For comparison, a standard 8-ounce cup of home-brewed coffee typically contains between 95-200 mg of caffeine. A 2020 study found the average at around 150.5 mg per standard cup. And so, it makes Dunkin's offerings considerably stronger.
Personalize Your Dunkin' Order

Dunkin' offers endless ways to personalize your drink beyond just choosing a size.
Flavor Shots and Swirls
Add flavor shots (unsweetened) or swirls (sweetened) to customize your coffee. Popular options include French vanilla, caramel, mocha, and seasonal flavors. The standard number of flavor pumps scales with cup size:
- Small: 2 pumps
- Medium: 3 pumps
- Large: 4 pumps
- Extra Large: 5 pumps
Extra Espresso Options
If you need more caffeine, then you can try adding extra espresso shots to any drink:
- Small: Holds 1 extra shot
- Medium: Accommodates 1.5 extra shots
- Large: Fits 2 extra shots
- Extra Large: Handles 2.5 extra shots
How to Order Like a Pro
Dunkin' staff recommend ordering in this format: size + hot/iced + drink type + customizations.
For example: "Medium iced coffee with oat milk and a caramel shot" or "Large hot coffee with cream and sugar."
This clear ordering method helps ensure you get exactly what you want without confusion or delays.


Conclusion
Picking the right Dunkin' cup size makes all the difference in your coffee experience. It has modest 10 oz Small hot coffee to the massive 32 oz Large cold drink and so there are many options. Remember that cold drinks come in bigger cups than hot drinks, and caffeine levels jump significantly with each size increase. Β
And the next time you visit, try ordering with the format: size + hot/iced + drink type + customizations. This simple approach gets you exactly what you want.

How To Find Your Perfect Dunkin' Size
Your ideal Dunkin' size depends on several factors:
For a quick energy boost, choose Small hot (10 oz) or Small cold (16 oz). These provide enough caffeine without excess liquid.
For standard daily drinking, medium sizes (14 oz hot/24 oz cold) offer the best balance of volume and convenience.
For all-day sipping or sharing, go with Large (20 oz hot/32 oz cold) or Extra Large (24 oz hot). These generous portions last through lengthy meetings or commutes.
Consider your caffeine sensitivity too. If you're caffeine-sensitive, remember that Dunkin's Small hot coffee contains more caffeine than a standard 8 oz cup brewed at home.
