Burger King Whopper Jr.: Price, Calories and Nutrition (2026)

The Whopper Jr. is the Whopper scaled down to everyday size. Same flame-grilled beef, same mayo, lettuce, tomato, pickles, ketchup, and onion on a toasted sesame seed bun, just a smaller patty and a smaller price. In 2026 it carries 340 calories and a price that starts from $3.69, which makes it one of the smartest orders on the Burger King menu: real Whopper flavor without the Whopper commitment. It works as a light meal, a kids’ upgrade, or the burger half of a combo that leaves room for fries. Here is the current price, the calorie count, and the full nutrition breakdown.

What is in the Whopper Jr.

The Whopper Jr. takes the full Whopper build and shrinks it. The patty is smaller than the quarter-pound Whopper patty, but it still goes over the same flame grill, so the smoky flavor is intact. It gets the same dressing: mayonnaise, shredded lettuce, tomato, crinkle-cut pickles, ketchup, and sliced onion, all on a toasted sesame seed bun sized to match.

At 340 calories, the Whopper Jr. sits in a sweet spot. It is a genuine burger, not a slider, and the 15 grams of protein gives it enough substance to work as a light meal on its own. It is also the burger parents order when the kids’ menu feels too small but a full Whopper is too much. The topping-to-beef ratio actually runs a little higher than the big Whopper, which means every bite has more of that fresh vegetable crunch.

Older nutrition listings put the Whopper Jr. at 330 calories; current 2026 data lists it at 340. The difference is trivial in practice, but the 340 figure is what today’s menu data shows, so that is the number to use when you are counting.

Whopper Jr. nutrition facts

Full nutrition breakdown for one Whopper Jr., based on Burger King’s official US nutrition data as reported by 2026-updated nutrition databases.

Nutrient	Amount per Whopper Jr.
Calories	340
Total fat	19g
Total carbohydrates	30g
Protein	15g
Sodium	630mg

These are friendly numbers for a fast food burger. Three hundred forty calories with 15 grams of protein fits comfortably into almost any eating plan, and the 630 mg of sodium is moderate by burger standards, well under a third of the daily guideline. The 19 grams of fat is mostly a mayo story, which means it is also the easiest thing to change.

The Whopper Jr. is one of the rare fast food burgers that works as a genuinely reasonable lunch. Pair it with a value fries and a water and you have a complete meal in the 600-calorie neighborhood, which is hard to pull off with most burger menus.

Whopper Jr. ingredients and customization

The standard build is a flame-grilled beef patty, mayo, lettuce, tomato, pickles, ketchup, onion, and a sesame seed bun. Customization is free. Holding the mayo drops the burger to around 200 calories, which turns it into one of the lightest real burgers in fast food. Skipping the ketchup as well trims a little sugar, and extra vegetables add crunch at no calorie cost worth mentioning.

Adding cheese is the most common upgrade, and it is worth knowing what it costs nutritionally: roughly 70 extra calories and a meaningful bump in sodium. For most people the plain Jr. is satisfying as is, but cheese lovers will not break the calorie bank with a single slice.

Because the Jr. is small, it also doubles well. Two Whopper Jrs. give you more food and more protein than a single Whopper for a similar price in many markets, and some regulars swear by the two-Jr. order as the superior way to eat at Burger King.

Allergens

The Whopper Jr. contains wheat and gluten (sesame seed bun), sesame (bun topping), soy (ingredients in the bun and condiments), sulfites, and egg (mayonnaise). Anyone with a gluten, sesame, egg, or soy allergy should take care. Burger King kitchens handle many allergens and the grill is shared, so cross-contact is possible even on a customized order. Always check with the restaurant if you have a serious allergy.

Whopper Jr. vs Whopper

The regular Whopper is 710 calories with 34 grams of protein from $5.69. The Whopper Jr. is 340 calories with 15 grams of protein from $3.69. Same flavor DNA, roughly half the burger, and about two dollars less.

Choose the Whopper Jr. when you want a proper burger experience without a 700-calorie commitment, when you are pairing it with fries, or when you are feeding kids who have outgrown the kids’ menu. Choose the full Whopper when the burger is the entire meal and you want maximum satisfaction in one item. Many regulars order the Jr. as part of a combo and come out happier than the full-Whopper crowd, because the fries still fit.

Getting the best value on the Whopper Jr.

• At from $3.69, the Whopper Jr. is one of the cheapest ways to get the real flame-grilled Whopper flavor. The price-to-satisfaction ratio is excellent.
• The Whopper Jr. meal bundles the burger with fries and a drink at a combo price that beats buying the items separately. It is also one of the lowest-calorie burger meals on the menu.
• The two-Jr. strategy: ordering two Whopper Jrs. instead of one Whopper often costs about the same while giving you more total food and a better topping ratio. Ask about it; the register handles it fine.
• Check the Burger King app. The Jr. appears in value bundles and Royal Perks offers regularly, and it is sometimes featured in app-only two-for deals that make an already cheap burger even cheaper.
