Burger King Calories & Nutrition Facts (2026)

Where do Burger King calories and nutrition facts come from?

Every calorie count on this page comes straight from Burger King's own U.S. menu data rather than a third-party estimate, the same numbers that power the Nutrition Explorer on bk.com, read on Oct. 31, 2026. They reflect the 2026 recipes, including the updated Whopper and the all-white-meat nuggets that arrived in September.

Burger King lists calories, fat, saturated fat, sodium, carbs, sugar and protein for each standard build. If you customize an order, the totals change. The BK app works as a rough nutrition calculator here: build your order there and check the item details before you pay. A few things to keep in mind:

• Sauces count. A packet of Zesty Sauce adds 140 calories, Ranch 110 and Honey Mustard 110, while BBQ adds 35.
• Drinks swing the total. A large Coca-Cola is 320 calories; Diet Coke, Coke Zero, unsweetened tea and black coffee are 0.
• Meals multiply. A Whopper with medium fries and a medium Coke comes to 1,350 calories. Swap in a Diet Coke and the same meal drops to 1,080.

How many calories are in Burger King burgers?

Burger King burgers run from 260 calories for a plain Hamburger to 1,390 for a Triple Whopper with bacon and cheese. The Whopper sits in the middle at 710 calories, and a Whopper Jr. cuts that roughly in half at 340.

Cheese adds about 80 calories to a Whopper and bacon about 60, so a Whopper with bacon and cheese lands at 860. Each extra quarter-pound patty adds about 270 calories and 22 grams of protein. Sodium climbs fast on the specialty builds: the Texas Whopper, with bacon, cheese and jalapeños, has 2,130 milligrams.

If you want a burger under 400 calories, the Hamburger (260), Cheeseburger (300), Whopper Jr. (340), Rodeo Burger (340) and Bacon Cheeseburger (350) all qualify. More on the flagship is on our Burger King Whopper page.

How many calories are in a Burger King chicken sandwich?

A Burger King chicken sandwich has 410 to 790 calories, depending on whether it is grilled or fried. The grilled Flame-Grilled Chicken Sandwich is the lightest at 410 calories, the Royal Crispy Chicken has 600, the long Original Chicken Sandwich has 680, and the Spicy Original Chicken Sandwich tops the range at 790.

The Original Chicken Sandwich is the one to watch. It has 680 calories but only 23 grams of protein, because the breaded patty and mayo make up much of the total. The Flame-Grilled sandwich gives you 35 grams of protein for 270 fewer calories. Wraps are lighter still: a Flame-Grilled Chicken Wrap has 230 to 320 calories, and a Royal Crispy Wrap 290 to 390.

How many calories are in Burger King fries and sides?

Burger King fries have 300 calories for a small, 370 for a medium and 440 for a large, and a value size has 230. Onion rings are lighter at every size, from 230 for a small to 430 for a large. Have-sies, the half-fries, half-rings box, lands between the two at most sizes, though a large Have-sies is the heaviest of the three at 490.

Chicken Fries are a surprisingly light side or snack at about 27 calories a piece: 110 for 4, 220 for 8 and 340 for 12. Mozzarella Fries run 220 to 660 calories, and hash browns climb quickly, from 270 for a small to 700 for a large. The lightest side on the menu is Mott's Applesauce at 50 calories. See Burger King fries for sizes and prices.

What are the lowest-calorie and highest-protein picks at Burger King?

The lowest-calorie meal at Burger King is a Hamburger with Mott's Applesauce and a diet drink, at 310 calories. For the most protein per calorie, order the Flame-Grilled Chicken Sandwich (35 grams for 410 calories) or its bacon and Swiss version (43 grams for 560).

A few other combinations work well:

• Under 400 calories: a Whopper Jr. (340) with applesauce (50) comes to 390.
• Protein snack: 12-piece Chicken Fries have 20 grams of protein for 340 calories.
• Breakfast: the Ham, Egg & Cheese Croissan'wich has 18 grams of protein for 350 calories.
• Shakes: they run 560 to 670 calories, so treat one as dessert, not a drink.
• Frozen drinks: a Freezee King slush has 100 to 160 calories by size, far less than a shake or a large regular soda.

At the other end, the Triple Whopper with bacon and cheese has the most protein of any sandwich, 87 grams, along with 1,390 calories. Our Burger King breakfast guide covers the morning menu.

Does Burger King have gluten-free, vegetarian or allergen options?

Burger King publishes allergen and ingredient details for each item in its online menu, but it does not offer a gluten-free bun. We found no gluten-free bun anywhere in Burger King's U.S. menu data in October 2026.

Some details that matter if you are avoiding an allergen:

• Wheat: Buns, breaded chicken, Chicken Fries and onion rings all contain wheat. The French fries' ingredient list has no wheat, but Burger King's allergen data still flags wheat for them, so treat them as a cross-contact risk.
• Milk, egg and soy: These show up in cheese, sauces, croissants and many buns. A plain Whopper lists egg, soy, wheat and sesame; adding cheese adds milk.
• Vegetarian: The Impossible Whopper (670 calories) uses a plant-based patty, but Burger King notes it is cooked on the same broiler as beef, and it comes with mayo, which contains egg.

Shared fryers and prep areas mean cross-contact is always possible. If you have a serious allergy, check the item details in the BK app and talk to the store before you order. For prices next to these calories, see the full Burger King menu.
