Burger King French Fries & Onion Rings: Sizes, Prices & Calories (2026)

How much are fries at Burger King?

Burger King fries cost about $2.49 for a small, $3.19 for a medium and $3.89 for a large at a typical store, based on our price estimates. Delivery apps charge more: a July 2026 delivery menu listed fries at $4.29. Each owner sets prices, so your store may differ.

The cheapest ways to get fries are bundled. A medium fries counts as one item in the $5 Duo and $7 Trio, and every meal includes fries sized to match. Royal Perks members can trade 200 Crowns for small fries or 400 for a large.

Is a bigger size worth it? At those estimated prices you pay roughly the same per gram at every size, so buy the amount you will actually eat. A large weighs about 239 grams, a medium about 200 and a small about 160, per Burger King's menu data.

What are Burger King French fries made of?

Burger King's fries are made from potatoes with a light coating of modified potato starch and rice flour, plus salt, leavening, dextrose and xanthan gum. That light coating helps them crisp up in the fryer. They are cooked in vegetable oil, which Burger King lists as either a corn and cottonseed blend or a corn, canola and hydrogenated soybean blend.

There is no wheat in the fry ingredients, but Burger King's allergen data still flags wheat for them as a possible cross-contact risk, since fryers and prep space are shared. If you need to avoid gluten, ask the store how its fryers are used. Our Burger King nutrition page covers allergens in more detail.

Does Burger King have onion rings?

Yes. Onion rings are a permanent side at Burger King in 2026, sold in value, small, medium and large sizes at 170, 230, 290 and 430 calories. Neither McDonald's nor Wendy's sells onion rings, so they are one of the best reasons to pick Burger King.

Burger King's rings are made from minced, dehydrated onion in a wheat-flour batter rather than whole sliced onion. A medium order runs about $3.39 in store by our estimate, and a July 2026 delivery menu listed onion rings at $4.29.

Can't decide? Have-sies give you half fries and half onion rings in one box, from 220 calories for a value size to 490 for a large, and the medium comes with Zesty sauce.

How do Burger King fries compare with McDonald's and Wendy's?

Burger King's fries are a bit heavier than its two biggest rivals', size for size. A medium order has 370 calories at Burger King, compared with 320 at McDonald's and 350 at Wendy's, based on each chain's 2026 menu data in our McDonald's vs Burger King vs Wendy's comparison. Prices are close: a medium ran about $2.99 to $4.19 at McDonald's and $2.99 to $3.49 at Wendy's in our checks, and about $3.19 at Burger King by our estimate.

The real difference is choice. Burger King is the only one of the three with onion rings and a half-and-half box, and its fries are among the items you can mix into the $5 Duo and $7 Trio.

Does Burger King have curly fries or other new fries?

No, Burger King does not sell curly fries; they are not on its 2026 menu. Its other fry-shaped items are made from something other than potatoes:

• Mozzarella Fries: breaded mozzarella sticks cut like fries, at 220, 440 or 660 calories for 4, 8 or 12 pieces.
• Chicken Fries: fry-shaped chicken strips, covered on our Burger King Chicken Fries page.
• Cheesy Bacon Tots: a limited-time fall 2026 side at 130 calories for 4 pieces.

Churro Fries have been sold at Burger King before, but they were not on the October 2026 menu. If you want cheese fries, order a nacho cheese sauce cup (110 calories) for dipping where your store offers it. The main Burger King menu lists every side and price.
