Free sandwich calculator: quick answers for a crowd
These starting quantities assume full-size sandwiches as the main meal, with sliders and finger sandwiches shown for platter-style spreads.
| Guests | Full-size sandwiches | Sliders | Finger sandwiches | Deli meat |
|---|---|---|---|---|
| 20 adults | 30 | 60 | 80 | 6 lb |
| 50 adults | 75 | 150 | 200 | 15 lb |
| 100 adults | 150 | 300 | 400 | 30 lb |
If you are serving three or more filling sides, you can cut the full-size sandwich count by about 15%. If you want leftovers, add 10%. These are estimates rather than guarantees — appetites, sides and event length all shift the real number.
For a full coworker lunch, the office party food calculator adds sides, dessert and supplies. To size the deli meat or pulled pork on its own, use the meat per person calculator, and for cans, bottles and ice see the party drink calculator.

How the estimate works & common mistakes
Plan about 1.5 sandwiches per adult for a meal, or 2 to 3 sliders since they are smaller. Kids usually eat one. The calculator scales this by guest count and party type.
Common planning mistakes
- Counting only full-size sandwiches when sliders fit a buffet better
- Forgetting kids - they eat less but still want one
- Not rounding up for Seconds and late arrivals
