How To Choose The Right Size Fireplace Screen

Single Panel Screens, Boston Sparkguards, Bowed Screens and Screen Doors

The ideal custom size for a single panel screen is 2" wider and 1" taller than the fireplace opening. This will provide the necessary spark protection while enhancing decorative appeal. Screens that are not custom made will still provide excellent spark protection as long as they are larger than the fireplace opening. As a general rule, up to 5" wider on each side may still look acceptable, but just how much larger is a judgement call you will need to make. Refer to these examples:

Custom Single Panel Fireplace Screen Good FitIdeal Custom Size: 1" overlap Each Side
1" Overlap Top
Single Panel Fireplace Screen NormalAcceptable: 3" to 5" overlap Each Side
3" to 5" Overlap Top
Single Panel Fireplace Screen Bad FitBad Fit: Does Not Overlap Top
or Does Not Overlap Sides

Folding Screens

For the best fit, we custom make our folding screens to be 25% wider and 3" taller than the opening. The width of the center panel should be 75% of the opening and each side panel should be 25%. This allows the side panels to be folded in at a 45 degree angle, which is the most stable and best look. But folding screens are very forgiving in size, so as long as you choose a screen that is roughly 20% to 50% wider and is taller than the opening, it can still be appropriate. Anything smaller in width will not be stable and can be knocked over easily. The width of the folding screens on our site is the combined width of the center panel and two side panels. Here are examples:
