How to choose the right barbecue size?

The type of grill one purchases does not only depend on the size and number of guests but also your expertise in barbecuing, presenting authentic flavors, space for the grill, and time expenditure on cooking. Each grill has its specificity for the delivery of food, the grills are;

  • Charcoal grill – also known as kettle grills has both direct and indirect grilling with temperatures of up to 700 degrees Fahrenheit delivering a charred flavor to meaty dishes. No precision temperature controls and high heat retention because of longer cool down and heat.
  • Gas grill – one of the basic models of grills with precise temperature control. It uses a 20-pound propane tank that lasts for 24 hours while in use. There are additional burners for cooking activities.
  • Electric grills – because of their small size they are an ideal choice for apartments. In addition, no fuel is required and they do not get very hot like other models.
  • Pellet grills – considered one of the high-end models, with an electrical outlet therefore, it doesn’t require propane canisters or natural gas. Has precision temperature controls.

How big is a standard BBQ?

The standard size for a BBQ grill especially for cooking hamburgers and hotdogs has a measurement of 360 square inches in case the crowd is bigger it increases to 400 square inches and it can reach a maximum size of 1200 square inches.

The grill surface influences the grill size you want because the width is equal to the cooking surface multiplied by the length to give its dimensions in square inches. The common size is 400 – 500 square inches of cooking space and it increases to 600 square inches if the family is larger and provides plenty of cooking area.

How do you measure the size of a BBQ?

To find the standard grill size, first, measure the height dimensions of your barbecue by placing a tape measure at the base of the grill to the highest point. Second, we obtain the dimensions of the width by placing a measuring tape on each end of the grill.

Last the depth is measured by closing the lid get the measurements from the back to the front of the barbecue including the lid handle and knobs.

How much room do you need for a BBQ?

For 400 to 450 square inches of cooking area, a three-burner gas grill is satisfactory for a typical home of 4-6 family members, but for a family reunion, a larger model of a grill with 5-6 burners that has a measurement of 550 – 650 square inches is approved.

Make sure to place the grill 10 feet away from plants and structures that could attract fire, and a charcoal grill should not be placed in an enclosed area to avoid fire hazards.


Apart from size and number of guests being the main factors when choosing a grill, other factors also play a key role in choosing the perfect size grill for you. Arrangement of the burners, lid design, and diffusion of heat will influence the grill type you purchase.

Alignment from the back to the front and vice versa allows even distribution of heat through the creation of heating zones. Metal heat diffusers shield the burners from drips and cleaning should be done regularly for correct heating.

A proper lid that closes well will prevent any heat to leak ensuring your food cooks nicely. Ensure your grill maintains a certain space of a few inches while outside grilling to prevent accidents.
