Size Guide

Measure the clear garage door opening—the area the closed door fills—not the surrounding frame, trim, wall, or header.

How to measure

  1. Width: Measure horizontally from the inside left edge of the opening to the inside right edge.
  2. Height: Measure vertically from the floor or threshold to the underside of the top opening.
For the best overall appearance, we recommend choosing Custom Size if your width or height differs from the closest standard size by more than 2 inches.
