How Many Ounces Is in a McDonald’s Large Drink? (Size Guide)
Have you ever grabbed a drink from McDonald’s and wondered, “Just how big is this?” You’re not alone. Sometimes, I feel like I’m carrying around a bucket of soda. McDonald’s doesn’t play around when it comes to drink sizes, but the question is: exactly how many ounces is in a McDonald’s large drink?
Moreover, does it change depending on where you order?
I did some digging—and some taste testing—to find out. Let’s break it all down in the simplest way possible!
How Many Ounces Is in a McDonald’s Large Drink? (Explained)

A McDonald’s large drink in the United States is 30 ounces. That’s almost two and a half cans of soda in one cup. To give you an idea, 30 ounces is just under four cups of liquid.
If you’ve ever felt like it lasts forever, that’s why! It’s the biggest size available for soft drinks at McDonald’s, giving you plenty to sip on.
Now, if you’re wondering how the large size compares to others, here’s a simple breakdown:
- Small: 16 ounces (about the size of a standard water bottle)
- Medium: 21 ounces (a little less than two cans of soda)
- Large: 30 ounces (a LOT of liquid)
So if you’re thirsty, a large is definitely the way to go!
If you’re keeping an eye on sugar or calories, it’s good to know that a large Coca-Cola at McDonald’s has around 280 calories and 76 grams of sugar. That’s more sugar than most people should have in an entire day!
If you want a healthier option, you might go for water, unsweetened iced tea, or a diet soda instead.
One of the reasons people love McDonald’s large drinks is the price. Many locations have the $1 any size drink deal, meaning you can get a large for the same price as a small. That’s a great deal, especially if you love getting a big drink without spending extra money.
Just keep in mind that prices of large drinks can vary depending on location.
Does the McDonald’s Large Drink Size Change by Location?
Yep! Not all McDonald’s serve the same large drink sizes. I checked menus from different countries, and here’s what I found:
- United States: Large = 30 oz
- Canada: Large = 32 oz
- United Kingdom: Large = 17 oz (smaller than a U.S. medium!)
- Australia: Large = 22 oz
- Japan: Large = 21 oz
So if you’re traveling, don’t assume “large” means the same thing everywhere. In some places, what we call a large in the U.S. is actually closer to a medium!
How McDonald’s Large Drink Compares to Other Fast Food Chains

McDonald’s isn’t the only fast-food place with big drinks. Here’s how they compare:
- Burger King: Large = 32 oz
- Wendy’s: Large = 32 oz
- Taco Bell: Large = 30 oz
- Chick-fil-A: Large = 32 oz
- Subway: Large = 30 oz
- Whataburger: Large: 32 oz
So while McDonald’s large is big, some places go even bigger! If you’re looking for the absolute largest drink, Burger King or Wendy’s might be the better choice.
Why Do McDonald’s Drinks Taste Better?
Have you ever noticed that McDonald’s Coke just hits differently? It’s not just in your head—there’s a reason for it!
- Special Water Filtration: McDonald’s filters their water more than most places. This makes sure every drink tastes fresh and crisp.
- Cold Syrup Storage: Most restaurants keep their soda syrup at room temperature. Not McDonald’s. They keep it cold so that when it mixes with the carbonated water, it tastes extra fizzy and refreshing.
- Bigger Straws: Yes, even the straw makes a difference! McDonald’s straws are wider than normal ones, so you get more soda with each sip. That’s why it tastes so good—you’re getting the full flavor right away.
FAQs
How Much Does a McDonald’s Large Drink Weigh with Ice?
A large drink with ice weighs around 2.5 to 3 pounds. The more ice you add, the less actual soda you get. So if you want more drink, ask for light ice!
Are All Large McDonald’s Drinks the Same Ounces?
No, not all large McDonald’s drinks in the U.S. are the same size. While most large soft drinks are 30 ounces, other beverages can vary. For example, large iced coffee is typically 22 ounces, and large McCafé drinks like frappés and smoothies are around 20–22 ounces. Sweet tea, however, usually sticks to the 30-ounce size like sodas.
Can You Get Free Refills on a Large Drink?
Yes—but only if you’re dining in! If you leave the restaurant, you can’t come back for a refill. So if you want to make the most of it, drink up before you go!
Conclusion
McDonald’s large drink is 30 ounces in the U.S., but sizes vary worldwide. If you love getting the most for your money, it’s a great choice. Plus, their drinks just taste better thanks to their special soda system.
So next time you grab a McDonald’s drink, you’ll know exactly what you’re getting. Now tell me—are you a small, medium, or large drink person? Let me know!
