Quick answer: The right wind guard should match the shape of your fire pit or fire table opening and provide 2.5 inches of clearance on each side. In most cases, that means choosing a wind guard that is 5 inches larger than the fire pit opening in the needed direction.
Fire pit wind guards are designed to complement your fire pit or fire table. They protect the flames from wind gusts that can cause sputtering, flickering or extinguish them altogether. Wind guards are also used to prevent loose items from getting too close to the flame, keeping you and your guests safe.
All of our DIY fire pit wind guards are made with tempered glass which ensures they are durable and built to last. We recommend having 2.5 inches of clearance on each side between your fire pit opening and the wind guard for optimal performance. The glass wind guards are meant to sit on the outside of your fire pit opening.
Wind Guard Sizing Formula
Use this simple formula when choosing a glass wind guard:
- Opening width + 5 inches = recommended wind guard width
- Opening length + 5 inches = recommended wind guard length
- Opening diameter + 5 inches = recommended round wind guard diameter
For example, if your fire pit opening is 20 inches wide, a properly sized wind guard should be about 25 inches wide overall. This allows for the recommended 2.5 inches of clearance on each side.
Wind Guard Shape Guide
The shape of the fire pit glass guard you need should correspond with the shape of the opening in your fire pit or fire table. We carry four distinct shapes of wind guards to ensure there is an option for many fire pit setups:
| Wind Guard Shape | Best For | How to Size It |
|---|---|---|
| Round | Round fire pits and round fire tables | Add 5 inches to the opening diameter |
| Square | Square fire pits and square fire tables | Add 5 inches to the opening width |
| Rectangle | Rectangular fire pits and fire tables | Add 5 inches to both width and length |
| Linear | Long, narrow burner openings and linear fire pits | Use width and length filters to match the burner opening |
Installation is easy. Simply connect the tempered glass pieces together with the included brackets and support feet, then set the wind guard on the outside of your fire pit opening and enjoy.
Shapes of Wind Guards
Once you know your fire pit opening size, choose the wind guard shape that best matches your setup. Use the Overall Width, Overall Length, or Overall Diameter filters while shopping to narrow your options.
Round Glass Wind Guards
Our selection of round glass fire pit flame guards pairs perfectly with our selection of round fire pits and fire pit tables. Because of the recommendation of 2.5 inches of clearance on each side, the overall diameter of your round fire pit glass surround should be 5 inches larger than the opening on your fire feature. Be sure to use the Overall Width filter while shopping our site.
Square Glass Wind Guards
When you've got a square fire table or fire pit, you'll need a square glass fire guard as well. With the recommended safety clearances, a glass guard for a square fire pit should be at least 5 inches wider than the fire pit opening itself for best performance.
Rectangle Glass Wind Guards
Rectangular fire pits and fire tables are a popular choice for many homeowners, and if you're one of them, you'll want to get yourself a glass fire guard to match. Because rectangle fire pits have two different dimensions, you'll need to ensure the guard you choose allows for the 2.5 inches clearance in both directions by using the Overall Width and Overall Length filters on our site.
Linear Glass Wind Guards
A linear glass fire pit guard is best for long, narrow fire features, especially those built around a linear burner opening. Linear wind guards are similar to rectangular wind guards, but they are typically designed for slimmer, longer flame areas. Like a rectangular fire guard, a linear guard must conform to your fire pit in both width and length, so be sure to use our site's filters while shopping to ensure you get exactly what you need.
