For typical packaged tortilla chips, a standard serving of about 1 ounce (roughly 28 grams, usually 8–12 chips depending on brand) has around 130–150 calories.

Quick Scoop

  • 1 ounce (28 g) tortilla chips: about 130–150 calories.
  • 100 g tortilla chips: about 470–500 calories, so they are a relatively energy‑dense snack.
  • Restaurant or flavored chips (ranch, taco, etc.) tend to be on the higher end of that range per ounce because of added oil and seasoning.

One quick example

If you casually munch through 3 ounces of tortilla chips during a movie, that’s roughly 390–450 calories just from the chips alone, before adding dips like guacamole or queso, which add even more.
