Why not use a weight-per-square-foot chart?

Published charts disagree by a factor of two or more. Gauge, foam, struts and windows all change the weight. One listed weight from your own model is a better base.

Can I weigh my garage door on a bathroom scale?

Not safely. Getting an honest weight means taking the spring tension off first, which is spring work. A technician does it. DASMA says only a trained technician should weigh a door.

Does adding windows or insulation change the springs?

It can. DASMA lists added components among the causes of a door exceeding its springs’ design. Ask a technician to re-check balance after adding weight.

Does door weight decide the opener size?

Less than people think. The springs carry the weight and the opener moves a balanced door. See what size opener you need .

Garage door weight calculator

Start from the weight the maker prints for one size of the same model. Charts online disagree too much to trust.

Same model is the only fair basis Weight depends on gauge, layers, foam, struts and windows. Scaling one listed weight by area keeps those the same.

This garage door weight calculator scales a weight the maker lists for one size of your model to the size you have. How much does a garage door weigh? It depends on the model.

One-layer and three-layer doors of the same size differ a lot, and online charts disagree by a factor of two. Use the estimate to plan and to read a quote. A technician weighs the door before sizing springs.

Your size, then a reference weight

Nothing is emailed. No preset weights.

What this assumed —

An estimate. HyreGarage does not weigh doors or size springs.

Why does this calculator ask for a reference weight?

Because no trustworthy per-square-foot weight exists for garage doors. Weight depends on the model, so the best starting point is the weight the maker prints for one size of that model.

Weight charts online disagree by a factor of two or more for the same kind of door. Steel gauge, the number of layers, the foam type, the struts and the windows all change it.

Makers and retailers often list an assembled or shipping weight for each size of a model. Take that number for any one size, and the tool scales it by area to the size you have. That keeps the model, the construction and the gauge the same, which is what a chart cannot do.

Then add anything bolted on since: windows, an insulation kit, decorative hardware, extra struts. DASMA warns that added components and even paint can push a door past what its springs were sized for (see counterbalance system).

What is a door weight estimate good for?

Planning and checking a quote. It is not good enough to order springs.

Checking an opener

Openers move a balanced door; the springs carry the weight. A heavy door still asks more of an opener if the springs are tired. See what size opener you need.

Comparing two new doors

A three-layer door weighs more than a one-layer door in the same size. More weight means different springs, and sometimes a different opener. See garage door materials.

Reading a spring quote

A quote for new springs should say what door weight they were sized for and their cycle rating. Run the rating through the spring life calculator.

Can I weigh my garage door myself?

No. Weighing a door means taking the spring tension off it first, and that is spring work.

A technician disables the counterbalance safely, then weighs the door, then sizes springs to that weight. Torsion springs, cables and bottom brackets hold enough stored energy to cause serious injury. Do not loosen them.

What you can do safely is the balance test: close the door, pull the manual release, lift the door to waist height and let go. If it drops or shoots up, the springs no longer match the door. Stop there and call a spring repair company.
