Home › Menu & Prices › Dunkin' Cup Sizes Guide: Ounces, Prices and the Best-Value Size

Dunkin’ cup sizes run from a 10-ounce Small hot cup to a 32-ounce Large iced cup, and each size name holds less for hot drinks than for iced and frozen ones. This guide lists every cup in fluid ounces, the drinks sold in each size and the price per ounce for 20 drinks. Prices are typical 2026 US prices and vary by location, because Dunkin’ stores are independently franchised.

Dunkin’ Cup Sizes Chart: Hot, Iced and Frozen in Ounces

Dunkin’ runs two size ladders, one for hot cups and one for iced and frozen cups. Hot cups go from a 10-ounce Small to a 24-ounce Extra Large, adding 4 to 6 ounces per step. Cold cups climb in even 8-ounce steps from 16 to 32 ounces. That is why a Medium iced cup holds 10 more ounces than a Medium hot cup.

These numbers describe cup capacity, not the amount of coffee you actually get. Ice fills part of every cold cup, and no published figure gives the coffee-to-ice split for each size. Frozen drinks such as Dunkin’ Coolatta flavors and Coffee Chillers use the same 16, 24 and 32-ounce cups as iced drinks.

Dunkin’ Donuts Cup Sizes by Drink, With 2026 Prices

Brewed Dunkin’ hot coffee and hot tea are the drinks that reach the 24-ounce Extra Large. Hot coffee runs from $2.29 for a Small to $3.49 for an Extra Large, and an XL tea is about $2.99 where a store pours one. Lattes, cappuccinos, macchiatos and hot chocolate stop at Large. Most iced, frozen and Refresher drinks use all three cold cups, and Dunkin’ iced coffee is the cheapest cold coffee at $2.99 for a Small.

The two tables show typical 2026 US prices for 20 drinks from the Dunkin’ coffee menu and the wider Dunkin’ drinks menu. Each franchise owner sets its own prices, and delivery apps usually charge more than the counter or the Dunkin’ app. Cells marked n/a are sizes a drink is not normally sold in, and cold ounces always include ice.

Drinks That Stop at Large

Hot lattes, chai and matcha all top out at a 20-ounce Large, so ordering iced is the only way to get a bigger cup of them. An iced latte comes in a 32-ounce Large for about $5.29, just $0.30 more than a hot Large at $4.99. For both versions side by side, see our Dunkin’ latte prices.

Espresso, Nitro and Box O’ Joe Sizes

A plain Dunkin’ espresso is sold as a single shot (about $1.99) or a double (about $2.49) rather than in a cup size. Nitro cold brew comes in a Small or Medium at about $4.49 to $4.99, with no Large, and its cup size in ounces is not confirmed. The Box O’ Joe is the one-size giant at 96 ounces for about $22.00–$30.00.

Price per Ounce: Which Dunkin’ Size Is the Best Value?

Divide each price by the cup’s ounces and one pattern holds: the largest cup wins on every drink we priced. A Small hot coffee costs about 22.9¢ per ounce against 14.5¢ for an Extra Large, a 57% premium for buying small. A Small iced coffee costs about 62% more per ounce than a Large at 11.5¢. Among the 20 drinks priced here, the lowest cost per ounce is a Large unsweetened iced tea from the Dunkin’ tea menu, at about 10.6¢.

Per-ounce value only counts if you finish the cup. Drink half of an Extra Large hot coffee and you paid about 29.1¢ for each ounce you drank, more than the 19.2¢ of a Medium you finish. Iced ounces also include ice, so compare hot sizes with hot sizes and cold sizes with cold ones.

What Each Size-Up Costs per Extra Ounce

Pricing only the extra ounces shows which upgrades are worth it. On hot coffee, Medium to Large costs about 5.0¢ per added ounce, while Large to Extra Large costs 12.5¢. The cheapest upgrade in the table is iced coffee from Small to Medium, at roughly 3.8¢ per added ounce.

Caffeine and Calories by Cup Size

Caffeine climbs with every size step, by about 99 mg per step on iced coffee and 30 to 60 mg per step on hot coffee. A Small hot coffee has about 180 mg, a Medium iced coffee about 297 mg and a Large iced coffee about 396 mg. That Large sits just under the 400 mg a day the US FDA cites as an amount not generally linked to negative effects in healthy adults.

Calories only climb with size once milk, syrup or a frozen base goes in, since black coffee stays near 5 calories in every cup. Frozen drinks and swirl coffees get more sweet base or syrup with every step, so a Large frozen coffee reaches about 810 calories, 400 more than a Small. For low-calorie orders in any size, see our healthiest Dunkin’ drinks guide.

Caffeine per Ounce and per Dollar

Hot coffee packs the most caffeine per ounce of cup, about 18 mg in a Small, because no ice takes up room. Iced coffee wins per dollar: a Large iced coffee gives about 107 mg for every dollar. Cold brew trails on both counts: a Medium costs $0.90 more than a Medium iced coffee and has about 37 mg less caffeine by these published estimates.

How Calories Grow With the Cup

On frozen drinks, a Large carries roughly twice the calories of a Small. A Vanilla Bean Coolatta runs from about 390 calories in a Small to 790 in a Large, and a Medium has about 125 grams of sugar. Its added sugar alone is more than twice the FDA’s 50-gram Daily Value.

Flavor Pumps Scale With Size

A Small gets 2 pumps of flavor, a Medium 3 and a Large 4. At about 50 to 55 calories and 12 g of sugar per swirl pump, a Large swirl drink carries 200 to 220 calories of syrup. Unsweetened Dunkin’ flavor shots add only 5 to 10 calories at any size, while a layer of sweet cold foam adds about 45 more.

Hot vs Iced: Why a Medium Iced Cup Holds 24 Ounces

Dunkin’ iced coffee sizes run bigger than hot ones, and ice takes up part of that extra room. A Small iced cup (16 oz) is bigger than a Medium hot cup (14 oz), and a Medium iced cup matches the 24-ounce Extra Large hot cup. A Medium iced coffee costs about $0.60 more than a Medium hot coffee and carries about 87 mg more caffeine.

The cleanest test is the same 24-ounce cup filled two ways. An Extra Large hot coffee ($3.49, about 330 mg) beats a Medium iced coffee ($3.29, about 297 mg) by 33 mg for $0.20 more, because the hot cup holds no ice. Cold brew in that same cup costs $4.19 and has about 260 mg; compare all three sizes in our Dunkin’ cold brew prices.

Cheapest Ways to Get More Coffee for Your Money

Size steps on brewed coffee are cheap, so one big cup costs far less than two small ones. Two Small hot coffees give 20 ounces for about $4.58, while one Large gives the same 20 ounces for $2.99. On iced coffee, swapping two Smalls for one Large saves about $2.29.

Deals can beat size math entirely. The Dunkin’ coupons and deals page tracks offers like the limited-time $6 Meal Deal, which includes a Medium hot or iced coffee, so choosing iced gets the 24-ounce cup instead of the 14-ounce one at no extra cost. Participation varies by store, and Dunkin’ Rewards app offers can lower the price further.

How to Choose and Order the Right Dunkin’ Size

Choose among Dunkin’ cup sizes by what matters most: total price, price per ounce, caffeine or calories. A Small is the cheapest cup to buy but the priciest per ounce, and the biggest cups are the reverse. Caffeine-sensitive drinkers should size by milligrams, since a Large iced coffee holds more than twice the caffeine of a Small hot coffee.

At the speaker or the counter, lead with temperature and size, then name the drink and any milk, flavor or foam. The Dunkin’ app shows your store’s own price for each size before you pay. Off-menu builds from our Dunkin’ secret menu ideas use the same cups, so the per-ounce math still applies.

Size Decision Table

Ordering a Size at the Counter, Drive-Thru or in the App

1. Start with temperature and size, for example Medium iced (24 oz) or Large hot (20 oz).
2. Name the drink, plus the roast for brewed coffee: Original Blend, Dunkin’ Midnight or decaf.
3. Add milk and flavor; a Small gets 2 pumps, a Medium 3 and a Large 4, so ask for fewer if you want it less sweet.
4. For iced drinks you can ask for light ice, but how much extra coffee that adds varies by store.
5. In the app, pick the size on the item screen and check the price before checkout.

Final Verdict: Which Dunkin’ Cup Size Should You Order?

Buy the biggest cup you will actually finish. That means an Extra Large hot coffee at about 14.5¢ per ounce or a Large iced coffee at about 11.5¢. Each size step usually costs just $0.20 to $0.50, so sizing up is rarely a big spend.

Size down when caffeine or sugar matters more than price. A Small hot coffee keeps you near 180 mg, and a Small frozen drink saves 230 to 400 calories against a Large. Dunkin’ Donuts cup sizes are standard, but prices are set store by store, so check the full Dunkin’ menu with prices and your app before ordering.

Dunkin’ Cup Sizes Guide: Frequently Asked Questions

Most questions about Dunkin’ cup sizes come down to one mix-up: the same name means a different cup for hot and cold drinks. A Medium iced coffee is a much bigger cup than a Medium hot coffee, so comparing by name alone misleads. The other common error is treating iced ounces as all coffee, when part of every cold cup is ice.

Cup volumes are Dunkin’s standard US sizes, confirmed by more than one source. Prices are typical 2026 US store prices, calories follow Dunkin’s published nutrition figures and caffeine figures are published estimates. Every store sets its own prices, so the per-ounce math shifts a little by location.
