How much does a garage door weigh?

It varies widely, and the size alone will not tell you. Two doors filling the same opening can differ a great deal, and the counterbalance is matched to the actual door.

The short answer

How heavy is a garage door? The short answer

There is no single weight for a garage door, and its size alone will not give you yours. Published figures put most modern single steel doors around 125 pounds and most double doors around 200 (The Genie Company, an opener maker), and DASMA, the industry association, says garage doors can weigh anywhere from 90 pounds to over 500. The classic double is 16 feet wide by 7 feet high (Clopay), and material, layers, insulation, windows, reinforcement, the finish and the hardware all move the number.

The published figures are ranges for doors in general, not your door’s number. That number comes from whoever made or installed it, in writing, or from a technician measuring it safely on site. The springs are sized to that number, not to the size of the opening. The sizes doors come in are a separate question from what they weigh.

Published figures

What DASMA and door makers say a garage door weighs

Here is each figure as its publisher prints it, with the publisher named. Nothing is averaged, and none of them is the weight of a particular size or model.

Garage door weights published by DASMA, Clopay, Garaga and The Genie Company
Door described	Figure as published	Published by
Any garage door	90 pounds to over 500 pounds	DASMA, the trade group: data sheet 176
Single door, most modern steel	Around 125 pounds; older and wooden doors weigh much more	Genie, an opener maker: blog, February 2022
Single door	150 pounds on average, and at least 130 pounds	Garaga, a door maker: blog, March 2020 and May 2015
Single-car door, upper figure	As much as 200 pounds	Clopay: install manual, the step for removing the old door
Double door, most	Around 200 pounds	Genie: blog, February 2022
Double door with windows	Up to 350 pounds or more	Garaga: blog, May 2015
Modern all-glass double door	Over 400 pounds	Garaga: blog, May 2015
Large door, upper figure	As much as 500 pounds	Clopay: install manual, the step for removing the old door

These are published figures for particular kinds of door, not a rule, and not weights we measured. Publishers differ: Haas Door says in its residential installation manual that a door can weigh up to 600 pounds, and a Chamberlain Group support article says garage doors can weigh from a couple hundred pounds to a thousand. The label identifies the door; its maker gives its weight.

What changes the weight

What it is made of Steel, aluminum, composite, wood — and in wood, which wood.
How many layers A single skin, or a layered section with insulation and a backing.
Windows Glazing is heavy, and where it sits changes the balance as well as the total.
Reinforcement Struts and wind reinforcement add real weight, and they are often invisible from outside.
The finish Overlays and applied cladding are not free.
Hardware Track, hinges, rollers and brackets differ by design and by duty.

Why an estimate is not good enough for spring work

The counterbalance is calibrated to a specific door. Springs sized from a guess will either not lift the door or will fight it, and either one wears the system and the opener while it does so.

This is the single reason it is worth knowing rather than assuming. It is not a detail; it is the specification the whole system is built around.

DASMA’s technical sheet on adding weight to a garage door says door springs are designed to accommodate the door’s original intended weight, and that weight added afterwards could leave the door unbalanced, possibly even damaging or breaking the springs. It strongly advises against untrained individuals attaching anything to a door without explicit instructions from the door’s maker. How long springs then last is its own question: how long garage door springs last.

How to find the real number

Look for the manufacturer’s label or the paperwork that came with the door
Take the model or series name from it, not just the brand
Ask the maker, or whoever installed the door, for that model’s weight in writing
If there is no label and nobody can say, a technician measures it properly on site

Where the line is

Do not try to weigh a door by disconnecting a spring, a cable or anything else holding it up. That is not a measurement, it is a release of stored energy with somebody standing under it.

Spring and cable work belongs to somebody trained for it. DASMA’s sheet on checking a door says only trained door systems technicians should remove, repair or adjust doors, springs or anything they are fastened to, and Amarr’s FAQ says not to attempt to remove, repair or adjust springs or cable.

Weight and springs

How springs are matched to weight, and what changes it

Springs are matched to a specific door. C.H.I. describes the springs on its model 2250 and 4250 residential doors as custom designed for exact door weight, size and trajectory, and DASMA’s official color code for extension springs is keyed to door weight in 10-pound steps. DASMA warns that not knowing whether a spring meets a door’s counterbalance requirement can shorten the life of the door and its opener’s motor, and could create a safety issue in manual operation. That is why the ranges above cannot pick a spring for you.

The weight can also change after the door is built. DASMA’s sheet on spring life says that paint or components added by a building occupant may push a door past the weight its maker specified, and that where paint appears to be adding weight, a trained door systems technician may measure the effect with a scale once the counterbalance has been disabled. Amarr’s installation instructions say that adding a strut to a door that came without one changes its weight and that different springs may be required. If your door has been painted or had parts added since it was installed, say so before a spring is chosen.

Straight answers

Questions people ask about this.

How heavy is a basic double-wide garage door?

Published figures vary. The Genie Company, an opener maker, says most double doors weigh around 200 pounds. Garaga says a double door with windows can reach 350 pounds or more, and a contemporary all-glass double over 400. Clopay’s installation instructions note that some large doors can weigh as much as 500 pounds. The classic double is 16 feet wide by 7 feet high (Clopay). For a specific door, DASMA says to contact its manufacturer.

How heavy is a 7 ft garage door?

Seven feet is a height. Clopay lists 8 by 7 feet and 9 by 7 feet as the two most common single-car sizes, and the same height applies to a 16 by 7 double, covered in the answer above. For a single door, the published figures are around 125 pounds for most modern steel doors (The Genie Company), 150 pounds on average and at least 130 (Garaga), and as much as 200 pounds (Clopay’s installation instructions). The Genie Company lists size, material, thickness, insulation and glass among the factors that set a door’s weight, so two 7 ft doors can differ.

Can the size alone tell me the weight?

No. Two doors filling the same opening can be built entirely differently — material, layers, insulation, windows, reinforcement, finish and hardware all move the number.

Where do I find my garage door’s weight?

Start with the door’s label and paperwork. The cover of Clopay’s manual for its Sleek aluminum doors, for example, has lines for the model, serial number and size, with a note pointing to a label on the interior door surface. Those identify the door, and DASMA says to contact the manufacturer for information on a specific door. If the label and the maker cannot tell you, a technician can check on site. DASMA describes a trained door systems technician measuring the weight added by paint with a scale once the counterbalance system has been disabled, which is not something to attempt by releasing a spring yourself.

Why does the weight matter?

Because the springs, cables, drums and opener are all sized to the real door. Get the weight wrong and the whole system works against itself, which you will hear before you see.

Should I try to weigh it myself?

No. Do not disconnect springs, cables or anything else carrying the door. Use the maker’s documentation, or have somebody measure it who is set up to do it safely.

Does insulation add weight to a garage door?

The Genie Company lists insulation, with size, material, thickness and glass, among the factors that set a door’s weight. This page prints no figure for what insulation adds. Changing a door after it was built is a separate matter: DASMA says the door could become unbalanced if weight is added after installation, possibly damaging or breaking springs, and it advises against untrained people attaching materials to a door without the maker’s explicit instructions.
