How much charcoal do you need for a BBQ?
Kilograms of briquettes or lump charcoal from meat weight, grilling hours, grill type and cooking style — plus bag count.
Quick answer
Charcoal scales with **meat kg** and **hours at the fire** — not just one or the other. Rule: **kg ≈ meat × 1.0 (briquettes)** plus burn for time after warm-up. **4 kg meat · 3 h · kettle · mixed grill** → **4 kg from meat + ~0.7 kg time component** → **~5 kg total** — two **3 kg bags** with leftovers for next time. **Lump charcoal** runs hotter and faster: use the **×1.2** meat factor in the tool.

⚠️ Estimates for one session — wind, damp briquettes or constant lid opening can burn 20–30% more. Never use lighter fluid on food that cooks directly over coals; a chimney starter is safer and tastes better.
Formula: kg ≈ meat × rate (1.0 briquettes, 1.2 lump) + max(0, hours − 1.5) × grill burn rate × style factor. Kettle ~0.35 kg/h after warm-up; indirect ribs need the higher style multiplier. Round up — leftover charcoal stays dry for next time.
How it works
Light with a **chimney starter** — never lighter fluid on food-grade coals. Pair meat weight with our BBQ meat calculator and drinks ice with the party ice calculator. **Indirect ribs** at 5 h on a kettle can hit **7–8 kg** — the style selector adds the extra burn.

Frequently asked questions
How much charcoal for 4 kg of meat?+
On a kettle with briquettes and a 3-hour mixed grill: about 5 kg total in the calculator. Quick 2-hour direct session (burgers only): ~4 kg. Five-hour indirect ribs: bump style to Indirect and expect 7–8 kg — buy an extra bag rather than running out mid-cook.
Briquettes or lump charcoal?+
Briquettes hold steady heat longer — best for mixed grills and beginners. Lump ignites faster and burns hotter, ideal for steaks and pizza on a kettle, but needs ~20% more by weight. The calculator applies 1.0 vs 1.2 kg per kg of meat automatically.
How do I light charcoal without lighter fluid?+
Fill a chimney starter to the top (about 2.5 kg), tuck two crumpled newspaper sheets underneath, light the paper. In 15–20 minutes coals are grey and ready — pour onto the grate, bank for indirect cooking if needed. One chimney load often isn't enough for a big party; the tool shows how many fills you need.
Why does a long BBQ use more charcoal per kg of meat?+
Coals keep burning while you cook sequentially — sausages first, ribs later, rest periods with the lid open. After the first 90 minutes you're mostly paying for heat maintenance (~0.35 kg/h on a kettle), not initial sear. Wind and damp briquettes can add another 20–30% — the calculator rounds up for that.
