Flour tortillas hold their shape better than corn tortillas, so the larger 10-inch tortilla sizes are often flour rather than corn. Smaller tortillas are traditionally used for tacos, and in Mexico, truly authentic tacos need to be cooked with corn tortillas. Burritos, quesadillas, enchiladas, and fajitas all need larger flour tortillas, however.
