To determine the size of gutter guard you need, measure the width of your gutter from the outer edge to the back where it attaches to the roof. Standard gutters come in 5-inch or 6-inch widths, so choose a guard that matches your gutter size for proper coverage and functionality.

Properly measuring your gutter ensures that you select the right size guard. Most gutters are 5-inch or 6-inch, and choosing the correct size ensures that the guard fits securely and prevents debris from entering the system.
