How to calculate what size gas BBQ do I need?

That's one tasty way to practice your math! To calculate the desired grill area, we're going to use the equation taken from our BBQ catering calculator:

  • Imperial version: Grill size = People * 72 in²
  • Metric version: Grill size = People * 464.5 cm²

Our tool easily converts between different units - however, if you need some help, you can always visit the length converter.

How much BBQ per person do I need?

We usually recommend buying at least 0.5 pound/8 ounces (0.23 kg) of meat per person. 🥩

Our BBQ grill size calculator performs that calculation in the blink of an eye - however, you may want to adjust that amount with the number of guests with vegan/vegetarian preferences.

If you need more specific calculations, we highly recommend you to try our tool dedicated to BBQ food & cost:
