How to Measure Garage Door Width
Follow these steps to accurately measure your garage door width for spring calculations and maintenance.
Step 1: Preparation
Before measuring, gather these tools:
- Tape measure (at least 16 feet long)
- Notepad and pen
- Stepladder (if needed)
- Helper (recommended)
Note: Ensure the garage door is fully closed and the area is well-lit.
Step 2: Measuring Door Width
To measure the door width:
- Measure from the inside of one track to the inside of the other track
- Take measurements at both the top and bottom of the door
- Verify both measurements match
- Record the measurement to the nearest inch
Step 3: Common Door Widths
| Door Type | Standard Width | Typical Use |
|---|---|---|
| Single Car | 8 feet (96") | Small to medium cars |
| Single Car Wide | 9 feet (108") | Larger vehicles, more clearance |
| Double Car | 16 feet (192") | Two standard vehicles |
| Double Car Wide | 18 feet (216") | Two larger vehicles, extra space |
Step 4: Important Tips
Where to Measure
- Inside track to inside track
- Both top and bottom of door
- Multiple spots for accuracy
- Clear any obstructions first
Common Mistakes
- Measuring outside edges
- Including track width
- Measuring only one spot
- Rounding numbers too much
Step 5: Additional Considerations
- Opening Width: The actual opening width may be slightly less than the door width due to weather seals and rubber molding.
- Track Clearance: Consider side room clearance requirements when planning any modifications.
- Multi-Door Garages: Measure each door separately as sizes may vary slightly.
- Building Codes: Check local building codes for minimum width requirements if planning modifications.
