How Many Tacos for a Party?

For 100 guests with tacos as the main dish, plan on about 25 dozen tacos, enough for 3 servings per person. That baseline holds for casual gatherings like birthday parties, Super Bowl parties, and 4th of July cookouts, but the right count shifts with the occasion: a Thanksgiving crowd needs closer to 8 dozen at the same headcount, since turkey carries the meal, while a graduation party can run up to 27 dozen, the highest of any event tracked here. Each quantity below already builds in a 15 percent buffer for extra helpings and stragglers, so there is little need to round up further.

If tacos are sharing the table with other dishes rather than anchoring the meal, cut the estimate to 2 servings per person instead of 3; a buffet spread stretches the same batch of shells and fillings across more plates. Tacos are ordered by the dozen here, with 12 servings in each, so a build-your-own taco bar with a few protein and topping options tends to use the quantity efficiently regardless of event size.
