The similar Mexican food that is usually larger and rolled rather than folded is the burrito.
A taco is generally made with a small tortilla folded around its filling, while a burrito usually uses a larger flour tortilla that is wrapped and rolled closed. The tortilla encloses fillings such as meat, beans, rice, cheese, vegetables, and salsa, making the burrito more substantial and portable.
The distinction is a useful general rule rather than an unchanging legal definition. Taco sizes, tortillas, and fillings vary across Mexico and the Mexican diaspora, and some regional foods blur the boundary. Even so, the contrast between a folded taco and a rolled burrito is the standard comparison in descriptions of Mexican dishes.
A sope is a thick masa base with raised edges and toppings; a chalupa is a fried tortilla preparation whose shape varies by region; and a tostada is usually a crisp, flat tortilla with toppings. None matches the specific combination of being typically larger and rolled rather than folded.
