Figure out exactly how many sandwiches, bread, and deli meat you need
💡 Why This Matters Whether it's a deli tray order or DIY sandwich bar, it's easy to under-buy bread or way over-buy deli meat without doing the math. Enter your guest count and whether sandwiches are the main event or a side option, and this works out exactly how much to order.
The sandwich is named after John Montagu, the 4th Earl of Sandwich, who reportedly asked for meat tucked between bread so he could keep playing cards without getting his fingers greasy — a habit that stuck.

This calculator scales sandwich quantities based on whether sandwiches are the main meal (1.25 whole sandwiches per person) or one option among several (0.75 per person). Each sandwich uses 2 oz of deli meat and 1 slice of cheese as a standard fill, and bread needs are converted into whole loaves (about 10 sandwiches per loaf). Condiment packets scale at 1.5 per person to cover mustard, mayo, and similar spreads.
The totals are shopping-list numbers for a deli order or DIY sandwich bar — how many loaves, how many pounds of meat and cheese, and how many sandwiches total. Round up to the nearest full loaf or deli-counter pound when you actually order, since it's much easier to have a little extra bread than to run short mid-assembly.
This assumes a fairly standard adult appetite and doesn't account for extra-large or double-decker sandwiches, which would use more meat and bread per person. If you're offering more than one filling option, the calculator assumes the deli meat total splits evenly across those options — adjust individual quantities if one filling is likely to be far more popular than the others.
Order deli meat and cheese sliced fresh the same day if possible, since pre-sliced packaged versions dry out faster once opened. Assemble sandwiches as close to serving time as you can to keep bread from getting soggy, or set up a DIY sandwich bar so guests build their own right before eating.
Example: Say you're hosting 15 guests with sandwiches as the main meal, 2 filling options. Sandwiches: 15 × 1.25 = 19 whole sandwiches. Bread: 19 ÷ 10 = 2 loaves. Deli meat: 19 × 2 oz = 38 oz ≈ 2.4 lbs. Cheese: 19 slices. Condiments: 15 × 1.5 = 23 packets.
Plan on 1.5 to 2 sandwich halves per person if sandwiches are one of several food options, or a full 1-1.5 whole sandwiches per person if sandwiches are the main meal.
Plan on about 2-3 oz of sliced deli meat per sandwich for a standard filling, which is roughly 3-4 slices depending on how thick they're cut.
A standard loaf of sandwich bread has about 20-22 usable slices, enough for roughly 10 whole sandwiches, so divide your total sandwich count by 10 to get loaves needed.
For groups over 10, offering 2-3 deli meat and cheese options (plus a vegetarian option) tends to satisfy more preferences than a single fixed sandwich for everyone.
