Before any number is useful, name the sandwich: Burger King chicken sandwich nutrition info splits three ways. The Original Chicken Sandwich runs 680 calories with 23 g protein; the Royal Crispy Chicken is 600 calories and 31 g protein; the Flame-Grilled Chicken Sandwich is 410 calories and 35 g protein. Apply the wrong line and you are off by hundreds of calories. The figures below are read from secondary databases (FastFoodNutritionCalc.com, NutriScan) that cite Burger King’s live Nutrition Explorer; confirm against that page before a medical use.
Quick answer. The Original Chicken Sandwich carries 680 calories, 23 g protein, 63 g carbohydrate, 39 g fat, and 1,380 mg sodium per sandwich. That sodium alone is more than half a full day’s reference intake. If protein per calorie is your target, the Flame-Grilled version delivers 35 g protein at 410 calories: the leanest of the three. The Royal Crispy sits between them at 600 calories. These values describe the standard single sandwich, before fries, sauce, or a drink.
The Three Burger King Chicken Sandwiches, Side by Side
The table below carries the per-item figures for the three current U.S. chicken sandwiches. Blank cells mark values the sources did not publish for that item.
| Sandwich | Calories | Protein | Carbs | Fat | Sodium |
|---|---|---|---|---|---|
| Original Chicken | 680 | 23 g | 63 g | 39 g | 1,380 mg |
| Royal Crispy Chicken | 600 | 31 g | |||
| Flame-Grilled Chicken | 410 | 35 g |
How One Chicken Sandwich Fits a Full Burger King Order
A sandwich is rarely the whole order. A sample build of a Whopper, a Medium French Fries, and a Medium Coca-Cola reaches 1,350 calories with 39 g protein, 177 g carbs, and 59 g fat: a marker for how fast a combo climbs.
Sodium Is the Number That Defines This Sandwich
The Original Chicken Sandwich’s 1,380 mg sodium is the figure most worth pausing on. The U.S. Food and Drug Administration states that “The Daily Value for sodium is less than 2,300 milligrams (mg) per day.” On that same FDA page, 20% DV or more per serving counts as high, and 5% DV or less counts as low. One sandwich at 1,380 mg clears the “high” line several times over.
One source puts the sandwich at “about 34% of a 2,000-calorie day and 60% of the 2,300mg daily sodium limit” in the U.S. That 60% is a published figure, not a derived one. For context, Americans average about 3,400 mg of sodium per day: the 2,300 mg limit is roughly 1 teaspoon of table salt.
Where the Sources Disagree on the Original Chicken Sandwich
This is the one comparison no single BK page lays out. Two secondary databases agree on the standard sandwich at 23 g protein and 63 g carbs. A separate line logs protein climbing from 34 g to 56 g to 78 g while carbs hold at 57 g, but the item or order context is not fully specified. The 23 g / 63 g pair is reported for the standard Original Chicken Sandwich; the item or order context for the higher numbers is not fully specified. If you need certainty for a clinical reason, read the item directly on Burger King’s Nutrition Explorer.
Burger King Medium Fries and the Combo Math
No standalone Medium French Fries calorie line is published; the Medium fry appears only inside the combo total of 1,350 calories. So the honest answer for a Burger King Medium Fries on its own: not separately stated in this data (read it on the Nutrition Explorer for the current figure). What the sources do fix is the drink load beside it. A Medium Coca-Cola is 270 calories with 70 g carbs; a Medium Sprite is 260; a Medium Barq’s Root Beer is 300; a Medium Hi-C Orange is 360. Swapping to water removes the largest avoidable block in the combo.
- Medium Coca-Cola: 270 cal, 70 g carbs
- Medium Sprite: 260 cal
- Medium Barq’s Root Beer: 300 cal
- Medium Hi-C Orange: 360 cal

Why a Dated Burger King Figure Can Mislead You
Recipes and suppliers change without a public announcement, which is why a number’s read-date matters. One secondary database checked its values against Burger King’s Nutrition Explorer on September 26, 2026; another read its figures on October 14, 2026. The Nutrition Explorer is the first-party source for current U.S. values and should decide any case where a figure here looks off. A swap worth naming: ordering the Chicken Fries (12 pc) instead, for 340 fewer calories and 20 g protein.
One Sandwich as a Share of the Day’s Sodium Limit
The Original Chicken Sandwich’s 1,380 mg of sodium is easier to judge once it is set against the FDA’s reference. Dividing 1,380 mg by the FDA Daily Value of 2,300 mg gives exactly 60% of a full day’s sodium in a single sandwich (1,380 / 2,300 = 60%), which matches the 60% figure the sources publish. More telling is how that compares to the FDA’s own cut-off for a “high” serving. At 1,380 mg, the sandwich is 1,380 / 460 = 3 times that “high” line in one item.
- 60% of the daily limit: 1,380 mg ÷ 2,300 mg × 100 = 60% DV from one sandwich, before any fries, sauce, or drink.
- What is left for the day: 2,300 mg − 1,380 mg = 920 mg of sodium remain to stay under the limit, roughly 40% of the day’s allowance for every other meal, snack, and drink combined.
These figures use the published 1,380 mg sandwich value and the FDA’s stated 2,300 mg Daily Value and 20% “high” threshold; confirm the sandwich number on Burger King’s Nutrition Explorer before any medical use.
