Plan for about 2–4 people to be able to eat off one camping grill. Generally, you should allow about 72 square inches of grilling space per person. For 2 people, that would be 144 square inches; for 3, 216 square inches should do it; for 4, 288 square inches. Larger than that and you’re probably talking about a grill that’s too big and weighs too much to take camping unless you’re in a pick-up or RV.
