A McDonald’s large sweet tea has about 370 calories on the current U.S. menu, with real numbers shifting slightly by recipe, region, and ice level.
A big cup of sweet tea at McDonald’s feels light compared with a burger or fries, so it is easy to forget that the drink itself carries a solid calorie load. When you ask how many calories in a McDonald’s large sweet tea, you are really asking two things at once: what the menu says today and what you actually drink once ice, refills, and local recipes enter the picture. Getting those pieces straight helps you decide whether a large sweet tea fits your calorie and sugar plans, or whether a smaller size or unsweet version makes more sense on a busy day.
How Many Calories In A McDonald’s Large Sweet Tea? Calories At A Glance
On the current U.S. digital menu, the large Southern Style Sweet Tea is listed at about 370 calories for a standard fill with ice. That number comes from McDonald’s own nutrition calculator and product page for the large sweet tea, so it is the best single figure to use when you want a quick answer based on the official menu rather than an estimate from a third party.
If you read food tracking sites or older nutrition booklets, you will see very different numbers for the same drink. Some databases still show a McDonald’s large sweet tea at 160 calories, others around 170 or 280 calories, and a “no ice” pour that climbs above 500 calories. Those figures are not mistakes so much as snapshots from different years, recipes, serving setups, and ice assumptions. For someone trying to track calories tightly, this spread explains why two apps can disagree about the same cup of tea.
To give you a clear picture of the range you might see, here is a comparison of large sweet tea calories drawn from both McDonald’s and leading nutrition databases as of 2025.
| Source | Serving Description | Calories (Large Sweet Tea) |
|---|---|---|
| McDonald’s product page | Southern Style Sweet Tea, large cup with ice | ≈370 calories |
| Fast Food Nutrition database | Large Sweet Tea, standard ice | ≈160 calories |
| Nutritionix listing | McDonald’s Sweet Tea, 1 large | ≈280 calories |
| FatSecret entry | Sweet Tea, large serving | ≈170 calories |
| Fooducate user entry | McDonald’s Large Sweet Tea, 30 fl oz | ≈220 calories |
| EatThisMuch “no ice” listing | Sweet Tea, large cup filled fully with tea | ≈560 calories |
| Older PDF menus | Legacy sweet tea recipe, large | Varies by year and outlet |
For day-to-day tracking, the safest move is to anchor on the official McDonald’s Southern Style Sweet Tea nutrition page and treat 370 calories as the default for a U.S. large sweet tea. When you see lower numbers in an app, there is a good chance they come from an older recipe, a lighter syrup mix, a smaller cup, or a fill level that assumes a big share of the volume is ice rather than tea.
If your local store uses a different regional menu, always check the in-restaurant nutrition poster, tray liner, or digital kiosk. The company notes that ingredients, syrup mixes, and beverage sizes can vary between markets, so the exact calorie count for how many calories in a McDonald’s large sweet tea in your country may sit a little above or below the U.S. figure.
McDonald’s Large Sweet Tea Calories By Size And Drink Choice
The main reason a large cup feels heavy on calories is simple: sweet tea at McDonald’s gets nearly all of its energy from added sugar. The larger the cup, the more sugary tea you pour in, and the more calories land in your day. Looking at nearby sizes and swaps gives you a sense of how much room you can save by changing the cup rather than dropping sweet tea altogether.
Regular Sweet Tea Cup Sizes
Most U.S. menus offer extra small, small, medium, and large sweet tea. A small sweet tea sits around 170 calories on the U.S. site, while the medium sweet tea with no ice is listed at about 200 calories and roughly 47 grams of sugar. By the time you reach the large Southern Style Sweet Tea, the official figure jumps to roughly 370 calories.
In practice, the drink you sip may land a bit lower than the numbers for “no ice” servings. A full cup packed with ice holds less liquid tea, so the energy you actually swallow can slide down toward the mid-200s if you do not ask for “light ice” or “no ice.” On the other hand, asking for light ice or refilling the cup from the self-serve fountain pulls you closer to the higher calorie end of the range because more sweetened tea fits into the same cup.
If you are trying to keep the same taste while tightening your calorie budget, moving from a large to a medium is the quickest change. You still get the sweet tea flavor, but knocking roughly one third off the volume can remove well over one hundred calories compared with a large sweet tea that is filled with very little ice.
Unsweet Tea And Other Low-Calorie Swaps
Not every tea at McDonald’s carries the same calorie load. Many locations offer unsweet iced tea or flavored water alongside sweet tea and soft drinks. An unsweet tea typically has 0–5 calories per cup because it is just brewed tea and water with no sugar syrup. That means you keep the habit of sipping a cold tea with your meal without stacking sugar calories on top of your food.
Another swap is to mix sweet and unsweet tea in the same cup. Some guests ask for half sweet, half unsweet. That type of blend cuts the sugar and calorie hit roughly in half, while still tasting like sweet tea instead of plain iced tea. If your store uses a dispenser with separate levers, you can mix your own ratio at the self-serve station and adjust the sweetness slowly over time.
Soft drinks, frozen lemonades, and creamy coffee drinks at McDonald’s often match or exceed the large sweet tea in total sugar. When you compare labels across the beverage menu, the large sweet tea usually lands on the higher side for added sugar, but not at the absolute top. Thai-style iced coffee drinks and some shakes can push the calorie count even higher than a large sweet tea, especially when whipped cream, syrups, and toppings join the cup.
How The Keyword Fits Here
Because the question how many calories in a McDonald’s large sweet tea keeps coming up in nutrition apps and forums, it helps to treat the number as a range rather than a fixed point. If you use 370 calories for planning, assume a slightly lower real-world load when the cup is very full of ice and closer to the high end when the cup is light on ice or refilled more than once.
Sugar In A Large McDonald’s Sweet Tea
Calories are only part of the story. A large McDonald’s sweet tea pulls almost all of its energy from added sugar. McDonald’s shows that a medium sweet tea with no ice carries about 47 grams of total sugar, all of it added sugar from the syrup used in the tea base. That already overshoots the daily added sugar target for many adults.
If you scale that same recipe up to the large Southern Style Sweet Tea, the sugar load likely lands somewhere between 70 and 90 grams for a fairly full cup of tea. Some “no ice” listings in nutrition databases quote around 141 grams of sugar for a completely filled large cup. Real-world servings sit below that extreme because most guests receive a mix of tea and ice rather than a cup filled edge-to-edge with sweetened tea.
Health groups keep a close eye on sugar from drinks because sweetened beverages are a large source of added sugar in many diets. The American Heart Association suggests a daily cap of about 100 calories of added sugar per day for most women (around 25 grams) and 150 calories per day for most men (around 36 grams). Their added sugar guidance notes that many people already exceed those limits before lunch when sugary drinks are part of breakfast or morning snacks.
Even at the lower end of the estimates, a large McDonald’s sweet tea can easily carry more than twice the added sugar target for a full day. That is why dietitians often point to sweet tea and soda as drinks to shrink rather than foods to cut first. Switching the cup size or choosing unsweet tea gives you an easier path to bring sugar down than reshaping your entire meal from scratch.
The table below gives a rough sense of how a large sweet tea fits within added sugar limits, using a mid-range estimate of 80 grams of sugar for a large cup that is mostly tea with a typical amount of ice.
| Guideline Or Reference | Added Sugar Limit (Per Day) | Share Used By One Large Sweet Tea* |
|---|---|---|
| Adult woman (AHA target) | ≈25 g (≈6 tsp) | ≈320% of daily limit |
| Adult man (AHA target) | ≈36 g (≈9 tsp) | ≈220% of daily limit |
| General 2,000-calorie diet cap | ≤50 g added sugar | ≈160% of daily limit |
| Medium McDonald’s sweet tea | ≈47 g sugar per cup | Already above many daily limits |
| Large sweet tea, heavy ice | Estimated 60–70 g sugar | Well above daily targets |
| Large sweet tea, light ice | Estimated 80–90 g sugar | Two to three days of added sugar |
| Unsweet iced tea | ≈0 g added sugar | No added sugar used |

How To Order McDonald’s Sweet Tea With Fewer Calories
If you like the taste of McDonald’s sweet tea but want to keep your calorie and sugar budget under better control, you do not have to give the drink up completely. Small adjustments to cup size, ice, and recipe can trim a large share of the calories while keeping the drink pattern that feels familiar.
Order Swaps That Cut Calories Fast
Start with the smallest shift that feels manageable. Moving from a large to a medium sweet tea already removes a big block of sugar and can also slow down refills. Ordering a small instead of a medium cuts even more calories out of your day, and it still gives you a cup that pairs well with a meal.
Another easy change is to ask for half sweet, half unsweet tea when the store offers both. That blend still tastes like sweet tea, yet it cuts the sugar and calorie load in a way that you notice less over time. If you like lemon in your tea, a squeeze of lemon brightens the flavor, which makes a less sweet cup feel more satisfying.
Choosing “regular ice” instead of “light ice” can also lower the calories you drink. When more of the cup holds ice, less of it holds tea syrup. You still get flavor, but the number of calories from sugar shrinks because the total volume of sweetened tea in the cup is smaller.
When A Large Sweet Tea Still Fits
There are days when you may decide that a large sweet tea is worth the calories, such as a long road trip or a rare stop on the way to a game. On those days, planning around the drink helps. Keeping food choices lighter, skipping dessert, and drinking water for the rest of the day can balance out some of the extra sugar from that single cup.
If you are managing diabetes, heart disease, or another condition where sugar intake matters a lot, ask your clinician what role a drink like McDonald’s large sweet tea can play in your plan. Many care teams suggest saving very sugary drinks for special occasions and leaning on water, unsweet tea, or diet soft drinks as everyday choices. For more detail on how added sugar ties into heart health, you can review the American Heart Association’s “How Much Sugar Is Too Much?” page.
The key takeaway is that how many calories in a McDonald’s large sweet tea is only one part of the story. Knowing that the official U.S. menu lists about 370 calories, understanding that real-world cups can swing lower or higher with ice and refills, and seeing how the sugar compares with daily limits gives you enough context to make a choice that fits your own goals each time you walk up to the counter.
