3 of the largest US chains list 15 menu items in this group (tacos). Among single orders, the lightest is the Taco Bell Soft Taco - Chicken (serving size not stated) at 160 calories and the heaviest is the Jack in the Box Taco, Regular (2 tacos, 162 g) at 340 calories.

Each chain sets its own portions, so a “medium” at one chain can be much larger than at another, and some chains give values for one piece or one slice rather than a whole order. The size column shows the serving each row’s values are for, as the chain publishes it (pieces, weight or volume); compare servings, not size names. Values are for the standard recipe.

There is one row per item. Calories show the range across every size the chain lists; the other columns are for the size and serving shown, usually the chain’s first listed size. A blank cell means the chain does not publish that value. Each item’s page has every size with full nutrition facts, and allergens where the chain publishes them.
