BBQ Quantity Calculator
Calculate meat, buns, and side quantities for a barbecue based on guest count and appetite level.
Adds veggie burger / halloumi portions for ~12% of guests (the typical 10-15% catering allowance)
How We Calculate This
This calculator uses standard UK BBQ-catering portion guidelines to estimate meat, bun, and side quantities. Meat is set per person as a raw-weight target, then split into whole burgers and sausages. The headline Total Meat is the raw weight you actually need to buy — the sum of the rounded-up burgers and sausages — so the figure always matches the shopping list rather than under-stating it.
Per Person Quantities (Raw Weight)
- Standard: ~275g meat, 1.5 buns, 100g salad
- Hearty: ~350g meat, 1.5 buns, 100g salad
- Light: ~200g meat, 1.5 buns, 100g salad
The 250–300g raw-meat-per-person figure is the widely used industry BBQ-catering heuristic for a mixed burger-and-sausage menu with 2–3 sides; scale toward the lower end when serving plenty of heavy sides.
Typical Meat Split
- 1 burger patty: ~150g raw
- 2 sausages: ~120g raw total (~60g each)
- Scaled proportionally for appetite level
Vegetarian Options
Tick “Include vegetarian options” to add veggie burger / halloumi portions for roughly 12% of guests — the mid-point of the usual 10–15% catering allowance. Adjust if you know your crowd. Cook vegetarian items on a separate part of the grill, away from raw meat, to avoid cross-contamination.
Food Safety
Burgers and sausages are minced or reformed meat, so they must be cooked right through to a safe core temperature of 75°C (or 70°C held for 2 minutes) — no pink in the middle and juices running clear. The same applies to chicken and pork. Use a meat thermometer to check the thickest part, and keep raw meat chilled and separate from cooked food and salads until it goes on the grill.
Frequently Asked Questions
The standard recommendation is 250-300g of raw meat per person for a barbecue. This typically includes a mix of burgers, sausages, and optionally chicken pieces or steaks. For hearty eaters, increase to 350g. For a lighter crowd or where there are plenty of sides, 200g is sufficient.
A good starting point is 1 burger (150g raw) and 2 sausages (60g each raw) per person, totalling about 270g of meat. Adjust up for hearty appetites. Some guests will prefer more of one than the other, so having a mix works well.
Allow 1.5 buns per person. Some guests will have a burger in a bun plus a sausage in a bun, while others may skip the bun. Having slightly more than one per person ensures nobody goes without. Buy a mix of burger buns and hot dog rolls.
Classic BBQ sides include coleslaw (80g per person), green salad (60g per person), potato salad (100g per person), corn on the cob (half per person), and bread rolls. Allow about 100g of salad sides per person in total when offering 2-3 options.
Allow 1-2 veggie burgers or halloumi portions per vegetarian guest. As a rough guide, assume 10-15% of your guests may be vegetarian unless you know otherwise. Keep vegetarian items separate from meat on the grill or use a separate cooking area.
People tend to eat slightly more at evening BBQs than lunchtime ones. Hot weather can slightly reduce appetites but increase drink consumption. If in doubt, stick with the standard quantities and have sides available to fill any gaps.
Burgers, sausages and any minced or reformed meat must be cooked all the way through to a safe core temperature of 75°C (or 70°C held for 2 minutes), with no pink meat and clear juices. Chicken and pork must also reach 75°C. Use a meat thermometer in the thickest part rather than relying on charring on the outside, as BBQ heat is uneven. Whole beef or lamb steaks (intact muscle) can be served less well-done at the cook's discretion, but burgers and sausages cannot. Keep raw meat chilled and separate from cooked food and salads until cooking.
