Sandwich Platter Calculator. Planning a party? Enter the number of guests, event type, and meal occasion into the Sandwich Platter Calculator to get back the exact number of sandwiches, bread loaves, and filling quantities you'll need. Adjust for adults vs. children and whether sandwiches are the main dish or a side — so you shop with confidence and nothing goes to waste. Also try the Taco Bar Calculator.
For a standard lunch where sandwiches are the main dish, plan for 2–3 half-sandwiches (or 1–1.5 full sandwiches) per adult. If sandwiches are part of a larger buffet with other mains and sides, 1–2 halves per person is usually sufficient. This calculator adjusts the count based on meal occasion and event duration.

Children aged 3–17 typically eat about half the amount an adult would, so they count as 0.5 of an adult serving in this calculator. Toddlers (1–2 years) are counted as 0.25 of an adult serving. This ensures you don't over-order for a mixed-age gathering.
A standard sandwich loaf contains roughly 20 usable slices, which makes 10 full sandwiches (or 20 halves). This calculator uses that figure to estimate how many loaves you'll need to buy. Always round up to the nearest whole loaf when shopping.
A standard sandwich typically uses about 60–85g (2–3 oz) of filling. Deli meat sandwiches use roughly 60–70g of meat per sandwich, while mixed fillings (meat + cheese + veg) average around 80–90g total. The calculator estimates total filling weight so you can plan your shopping list.
Yes — for events lasting 4+ hours, guests tend to return for second helpings or snack more throughout the day. This calculator automatically increases quantities by roughly 20–25% for longer events. It's always better to have a small surplus than to run short.
When sandwiches are one of several options on a buffet, you can reduce per-person counts by around 30–40% compared to a standalone meal. Select 'Buffet Side' as your meal occasion and the calculator will factor that in automatically.
Most sandwiches can be made up to 24 hours ahead if stored in an airtight container in the refrigerator. Avoid adding wet fillings like tomato or cucumber until closer to serving time to prevent soggy bread. Egg or tuna salad sandwiches are best made no more than 12 hours in advance.
Mini sandwiches work great for cocktail parties, afternoon teas, or events where guests are mingling rather than sitting down to eat. They're easier to handle and allow guests to try multiple varieties. Plan for roughly 4–6 mini sandwiches per adult when serving as a main, or 2–3 as a snack alongside other food.
