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

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:

What size gas BBQ do I need for 100 people?

We usually need 72 square inches (464.5 cm²) of grilling space for a single adult person.

With that information in mind, let's calculate what grill area is perfect for a party of 100:
