How Many Ounces Is Tim Hortons Extra Large Coffee?
The official answer is simple: a Tim Hortons extra large hot coffee is 24 fluid ounces, or about 710 millilitres. Tim Hortons lists this volume in contest and promotion rules for hot beverages, so it reflects the current standard cup size used in stores.

The chain has adjusted size names over the years, but the most recent information still puts the extra large hot coffee at 24 ounces. Smaller cups sit below that in a clear ladder of sizes.
| Tim Hortons Hot Coffee Size | Ounces | Approx. Millilitres |
|---|---|---|
| Extra Small | 8 fl oz | 240 mL |
| Small | 10 fl oz | 295 mL |
| Medium | 15 fl oz | 444 mL |
| Large | 20 fl oz | 591 mL |

Tim Hortons Extra Large Coffee Ounces And Other Sizes
Once you know that an extra large sits at 24 ounces, every other Tim Hortons cup size becomes easier to place. The extra small and small sizes match a single mug at home. Medium and large push you into multiple-mug territory, with the extra large at the top of the range.
Current Tim Hortons contest rules describe hot beverage sizes as small 10 ounces, medium 15 ounces, large 20 ounces, and extra large 24 ounces for eligible cups. That aligns with independent caffeine charts that list the extra large brewed coffee at about 330 milligrams of caffeine. You can see these volumes listed on the official Roll Up To Win rules page when promotions are active.
Why Tim Hortons Coffee Sizes Changed Over Time
Long-time guests may remember when a medium once meant 10 ounces and an extra large held 20 ounces. As bigger servings became common across the coffee world, Tim Hortons renamed its cups so that the same physical containers now carry new labels. The 24-ounce extra large grew out of that shift, while smaller cups slid down the naming ladder.
This history explains why older charts sometimes show different ounce counts for each name. What matters today is the current pairing of label and physical volume. When you scan the menu board, you can treat the small as 10 ounces, the medium as 15 ounces, the large as 20 ounces, and the extra large as 24 ounces.
How Tim Hortons Extra Large Compares To Other Coffee Chains
Plenty of coffee fans move between Tim Hortons, Starbucks, McCafé, and Dunkin without thinking about cup sizes. Yet the ounce count shifts from brand to brand. A Tim Hortons extra large coffee at 24 ounces is at the upper end of mainstream drip sizes, especially for hot drinks.
A Starbucks grande hot coffee sits at 16 ounces, while the venti hot size reaches 20 ounces. Many cold Starbucks drinks go higher, but for brewed hot coffee the 20-ounce venti is the usual ceiling. At Dunkin, hot coffee runs small 10, medium 14, large 20, and extra large 24 ounces, which lines up neatly with the Tim Hortons ladder.
That means when you choose a 24-ounce Tim Hortons extra large, you get more coffee than a Starbucks grande and even more than most McCafé cups. If you track caffeine across the day, that comparison helps you balance one big Tim Hortons run against smaller cups picked up elsewhere.
Quick Ways To Visualise A Tim Hortons Extra Large
If ounces feel abstract, use common items as shortcuts. A full 24-ounce Tim Hortons extra large coffee equals three full measuring cups of liquid. It also matches the volume of many refillable water bottles used at desks and gyms, which often sit between 20 and 24 ounces.
Another simple check comes from your kitchen cabinet. Fill your usual 8-ounce mug with water, pour it into a measuring jug, then repeat twice more. That stack of three mugs shows you the amount of hot coffee that lands in one extra large Tim Hortons cup.
Caffeine In A Tim Hortons Extra Large Coffee
The ounce count matters because caffeine tracks closely with volume. Tim Hortons brewed coffee made with the standard original blend has been measured at around 13 to 14 milligrams of caffeine per fluid ounce. That puts a 24-ounce extra large at about 330 milligrams.
Health agencies in Canada and the United States often set a general daily limit for healthy adults at around 400 milligrams of caffeine. Health Canada lists this cap on its caffeine in foods page, and the U.S. Food and Drug Administration cites a similar figure. An extra large Tim Hortons coffee comes close to that on its own, especially if you tend to drink other caffeinated drinks like tea, cola, or energy drinks in the same day.
If you like stronger dark roast, the caffeine number can shift slightly, though the ounce volume stays fixed at 24. The safer habit is to count an extra large cup as a near full day’s worth of caffeine and plan the rest of your drinks around that.
Who Should Be Careful With An Extra Large Cup
People who are pregnant, planning pregnancy, or breastfeeding often receive advice to keep daily caffeine well under 400 milligrams. In that case, an extra large Tim Hortons coffee might push your intake past the suggested level in a single drink. A small or medium size leaves more room for tea, chocolate, or other sources through the day.
Teens and younger children are more sensitive to caffeine as well. Health bodies usually urge parents to limit caffeinated drinks for kids, and a 24-ounce extra large would sit far beyond those suggested amounts. Younger guests are better off with smaller hot chocolates, plain milk, or caffeine-free choices instead of sharing a huge brewed coffee.
| Hot Coffee Size | Approx. Caffeine (Brewed) | Share Of 400 mg Daily Limit |
|---|---|---|
| Extra Small (8 oz) | 80 mg | 20% |
| Small (10 oz) | 140 mg | 35% |
| Medium (15 oz) | 215 mg | 54% |
| Large (20 oz) | 270 mg | 68% |
| Extra Large (24 oz) | 330 mg | 83% |
| Starbucks Grande (16 oz) | 190 mg | 48% |
| Dunkin Medium (14 oz) | 210 mg | 53% |
Choosing The Right Tim Hortons Coffee Size For You
Knowing that an extra large carries 24 ounces and about 330 milligrams of caffeine helps you decide whether it suits your day. Some people feel fine with that amount in a single cup, while others sleep poorly or feel jittery after crossing the 200 to 300 milligram range.
If you are sensitive to caffeine, a small or medium Tims coffee may suit you better, especially later in the afternoon. Morning commuters who finish their cup before work might feel comfortable starting with a large or extra large, then sticking to water or decaf later on.
Health Canada and the U.S. Food and Drug Administration both place a 400 milligram daily limit for most healthy adults, with lower suggested caps for people who are pregnant, planning pregnancy, or breastfeeding. Anyone in those groups may want to stay below a full extra large and treat that 24-ounce cup as an occasional treat.
Sample Daily Coffee Plans Using Tim Hortons Sizes
One simple plan is a medium Tim Hortons coffee in the morning and a small in the early afternoon. That pattern keeps you under the 400 milligram mark while still giving you two solid hits of brewed coffee. Someone who prefers one big drink could swap those two cups for a single extra large early in the day, then move to water and herbal tea later on.
Another pattern suits people who split their coffee between home and a Tim Hortons stop. Brew an 8-ounce mug at home, then grab a small or medium at the drive-thru. Together, those cups land under the caffeine load of a single extra large, yet you still get that steady alert feeling through the morning.
Practical Tips For Enjoying An Extra Large Tim Hortons Coffee
Once you know the answer to how many ounces is tim hortons extra large coffee?, you can tweak your order so that every sip feels balanced. A 24-ounce hot drink stays warm for a while, so think about how fast you drink and how far you travel with it.
If you like a milder drink, ask for extra cream or milk so the large volume does not taste harsh by the time you reach the bottom. If you want more punch, a shot of espresso layered into the extra large adds flavour without changing the 24-ounce cup size, though the caffeine number climbs.
Many regulars split a single extra large into two servings. You might drink half on the way to work, then reheat the rest later in a safe mug. Another trick is to order an extra large in the morning and pour some into a travel tumbler with ice for an afternoon iced coffee without a second caffeine purchase.
Handling Temperature And Reheating Safely
A fresh extra large arrives hot, so take care with the first sips. Sip slowly at the start rather than taking large gulps. The lid helps keep heat in, yet it also hides steam, so give the cup a gentle tilt to test the temperature before you drink.
Once the drink cools, shift it into a ceramic mug or travel tumbler before reheating. Paper cups are not meant for long microwave sessions, and moving the coffee into a microwave-safe container reduces the risk of spills. With a little planning, that single 24-ounce Tim Hortons extra large coffee can carry you through a long stretch of the day without waste.
A Tim Hortons extra large coffee gives you a lot of room to personalise your drink. Once you have the 24-ounce figure in your head, you can match that size to your schedule, caffeine tolerance, and budget instead of guessing every time you reach the counter.
