How Many Sandwiches for 25 People?

Plan 1.5 sandwiches per person for a lunch spread, using about 3 oz of deli meat per sandwich. For bigger groups a 6-foot party sub (feeds 20–25) is cheaper and more dramatic.

Cut sandwiches in halves or quarters — people take smaller pieces and total consumption drops noticeably.

Adjusting for your crowd: kids eat about two-thirds of adult portions; knock 25% off any single item when several mains share the table; add 25% for teenagers and big appetites. When in doubt, round up on the cheap items (buns, chips, ice) and stay exact on the expensive ones.
