Measure your gutter across the top from the back where the gutter meets the home to the outer edge. (See photos below) Most residential gutters will measure approximately 5 inches across the top with the actual opening being approximately 4.5 inches.

GutterBrush comes in 5 sizes, of which the actual bristle diameters are 3.25", 4.25", 5.25", 6.5" and 8". Choose the size that best fills the width of the gutter without overly compressing the bristles; a raised or "crowned" profile is desirable but not imperative.
Do you have Fascia Style Rain Gutters? (depicted below, common in Western U.S) CLICK HERE for more information about how our gutter guard works with Fascia gutters. Fascia Style gutters come in a few different configurations and we have found that most fascia gutters seem to be protected best when outfitted with Standard GutterBrush for 5" gutters, which has an actual diameter of 4.25 inches.
Metal building gutters come in many different sizes and profiles. GutterBrush comes in large sizes that fit metal building gutters. The best GutterBrush fit should fill the width of the gutter without overly compressing the bristles. It may not be possible to have a crowned or raised bristle profile, because often because with metal buildings, the front edge of the gutter is designed to be even higher than the roof drip edge; because the front edge of the gutter is strapped to the upper portion of the roof panel ribs.Click here to visit Large Gutters Guards, Commercial and Industrial
