There is no reliable universal weight chart based only on width and height. A 16-by-7 door can be single-layer steel, insulated multi-layer steel, aluminum and glass, composite, or wood. Windows, struts, wind reinforcement, paint, and decorative hardware can change the load.
The Door & Access Systems Manufacturers Association says garage doors can range from about 90 pounds to more than 500 pounds in its technical sheet on adding weight to a garage door assembly. That broad range is useful for understanding the hazard, not for selecting a spring.
What changes the weight
- Door width and height
- Steel, aluminum, glass, composite, or wood construction
- Number of layers and insulation
- Window quantity and glass
- Wind-load reinforcement and struts
- Finish, paint, and applied trim
- Section and hardware design
Amarr specifically warns that painting a steel garage door adds weight and may affect spring settings and opener performance.
Why an estimate is not enough for spring work
The counterbalance system is designed around the actual door assembly. DASMA’s technical guidance on torsion springs warns that applying a spring to the wrong door can reduce cycle life, affect the operator, and create a manual-operation safety problem. It recommends verifying spring parameters against the door manufacturer’s instructions.
That is why an internet weight estimate should never be used to order or wind springs.
How to find the right information
Use this order:
- Find the manufacturer and model label on the door.
- Check the exact product literature for size and construction options.
- Record windows, reinforcement, insulation, finish, and added hardware.
- If documentation is unavailable, have a trained door-systems technician identify the system and measure it using an appropriate procedure.
Safety boundary
Do not loosen, remove, or adjust springs, cables, drums, bottom brackets, or spring anchors to weigh the door. These components can be under high tension. DASMA’s consumer safety guidance recommends trained technicians for spring and cable work.
If you need help identifying a residential or commercial door, send the manufacturer label and photos with the service address.

Common questions
Can door size alone tell me the weight?
No. Two doors with the same dimensions can weigh very different amounts because of material, layers, insulation, windows, reinforcement, finish, and hardware.
Why does garage-door weight matter?
The counterbalance system, springs, track, hardware, and operator must work with the actual door assembly. Incorrect assumptions can produce poor operation, damage, or a safety hazard.
Should I weigh a garage door myself?
Do not disable or adjust springs, cables, drums, bottom brackets, or other tensioned components. Use manufacturer documentation or a trained door-systems technician.
