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.

What size grill do I need for 10 people?
It's so easy! You'll only need two steps:

Take a look at the equation:
Grill size = People × 72 in²

Grill size = 10 × 72 in²
Grill size = 720 in²

Yay! Your grill for a party of 10 should be at least 720 square inches! 🍾
What size barbecue do I need for a party of 20?
Let's get it done! Here's the equation you'll need:
Grill size = People × 72 in²
Grill size = 20 × 72 in²
Grill size = 1440 in²
Now you know! The BBQ you need to host a party for 20 people should be around 1440 square inches.

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:
Grill size = People × 72 in²
Grill size = 100 × 72 in²
Grill size = 7200 in²
That's one enormous BBQ! It wasn't that difficult, was it? 🎉
