The weight of a garage door varies significantly based on its size, material, and whether it’s insulated or not.

Knowing your garage door’s weight can help you maintain it better and ensure its longevity. It can also prevent unnecessary strain on your opener. So, let’s dive into the world of garage doors and uncover the mystery of their weight.

Key Takeaways

  • The weight of a garage door is determined by several factors including its size, material, and whether it is insulated.
  • Larger garage doors are usually heavier. An 8×7 foot non-insulated steel door can weigh around 65 pounds, while a 16×7 foot door of the same material can weigh up to 150 pounds.
  • Different materials also result in different weights. Steel doors tend to be heavier than aluminium, but lighter than wood. A standard 16×7 foot door can have a substantial weight difference depending on the material used.
  • Insulated garage doors, designed for temperature regulation, tend to be heavier. Insulation can add an estimated 25% to the door’s weight.
  • Knowing your garage door’s weight helps ensure its longevity and prevent unnecessary strain on your opener. It should also be factored in when considering a replacement door or opener.
  • Safety is a critical consideration in relation to garage door weight. Overloading an automatic door opener could result in potential injuries and property damage. A correct weight estimate ensures longevity of the door opener and cost savings in the long run.

Factors Affecting Garage Door Weight

When it comes to the weight of your garage door, several factors come into play. Notably, size, material, and insulation play a vital role in determining how much your garage door will weigh.


Let’s start with the size. The larger the garage door, the heavier it’s going to be. Standard garage doors come in multiple widths, ranging from 8 to 20 feet. To get an idea of weight, an 8×7 foot non-insulated steel door can weigh around 65 pounds. On the other end of the spectrum, a 16×7 foot same material door can weigh as much as 150 pounds.

As you can see, there’s a considerable increase in weight as the size goes up.


Next, let’s consider the material. Garage doors can be made from a variety of materials – each with its own weight implications. Steel is typically heavier compared to aluminium, but lighter than wood.

By just changing the material, the weight of a standard-sized 16×7 foot door can change drastically.


Lastly, insulation can significantly affect garage door weight. Insulated doors are designed to keep your garage temperature regulated, but that extra layer of insulation adds to the overall weight. It’s estimated that insulation can add about 25% to the weight of the door.

By understanding the factors that affect garage door weight, you’re better equipped to choose the right door for your needs and to understand how it might impact your garage’s structure and door opening system.

Average Weight of Different Garage Door Types

As you continue your journey to uncover what influences the weight of your garage door, you’ll find that different types play a significant role. Each unique garage door type comes with its average weight, significantly influenced by size, material, and insulation. The specifics of these categories can mean the difference between a garage door that works perfectly for your needs and an overly-heavy door straining your opening system.

Steel garage doors are the middleweights of the field. They are not as light as aluminum doors but significantly lighter than solid wood. An average 8×7 foot steel door weighs around 65 pounds, while a larger 16×7 foot door can weigh up to 150 pounds. Add insulation to the mix and you can expect an approximate 25% increase in weight. That’s an important fact to consider if you’ve got energy efficiency on your mind.

On the lighter end of the spectrum, you’ll find aluminum garage doors. The same 8×7 foot size you learned about earlier comes in at a breezy 50 pounds, with the double-sized 16×7 foot door weighing just 100 pounds. Insulation, of course, adds a little more weight.

While wooden garage doors offer an aesthetic appeal to many homeowners, they tip the scales as the heaviest garage door type. A standard 8×7 foot door clocks in at around 100 pounds, with the larger 16×7 foot door reaching as much as 200 pounds. Wooden doors also have the potential for even more weight if you decide to include windows or use denser wood types.

How to Determine the Weight of Your Garage Door

When it comes down to considering how much your garage door weighs, you’ll disentangle it’s weight mainly by its size, material, and whether it has insulation or not.

To put this into perspective, let’s think about a typical 8×7 foot garage door. Depending on the material it’s made from, the weights could be drastically different.

For instance, a similar-sized steel door generally tips the scales at around 65 pounds, while an aluminum door remains on the lighter end at 50 pounds. However, a wooden door could reach up to 100 pounds, showcasing the significant weight variance purely based on material.

Keep in mind that these are just averages. Your garage door could still be quite different depending on its exact size, material quality, and type.

Moreover, there’s an important note about insulation. An insulated garage door is great for maintaining the temperature in your garage, but it will increase the weight of your door. On average, insulation increases a door’s weight by about 25%. That’s an additional 25% you need to carry in mind if you have an insulated garage door.

In the end, determining the exact weight of your garage door can be tricky. If you are looking to replace your existing garage door system, it’s always best to consult a professional. They are equipped with the correct tools and knowledge to handle this process accurately and safely. Remember, handling a garage door improperly can result in damage or injury.
