FAQ
How do I know if my garage door size is a standard or custom dimension?
Compare your rough opening measurements (width × height) to the standard sizes listed on the chart. If your numbers don’t match exactly, you’ll likely need a custom door. Measure from the inside edge of the header to the floor on both sides for accuracy.
Can I use these charts if I’m installing a side-hinged or overhead-door style?
These charts cover standard residential garage doors, including single and double-car models. Side-hinged doors may require different clearance measurements, so always cross-check with manufacturer specs. Overhead doors typically follow width/height standards but check for track or header requirements.
What should I do if my garage ceiling height doesn’t match the chart’s standard options?
If your ceiling is unusually high or low, you’ll need a custom-height door. The chart can still help estimate the closest standard size for pricing comparisons, but consult a local dealer to confirm availability and ensure proper spring/balance adjustments for non-standard heights.
