Garage door dimensions explained simply
Why are the right dimensions important? To ensure that your garage door works properly later on, the dimensions must be correct. If the door is planned to be too large or too small, installation can be difficult or the door may not run properly. Therefore, the width, height and space around the opening should be checked carefully – especially when building a new house or replacing an old door.
Typical door sizes
The size depends on whether it is a single or double garage.
Single garage (standard size)
- Width: approx. 2.40 – 2.50 m
- Height: approx. 2.00 – 2.13 m
Double garage
- Width: approx. 4.50 – 5.00 m
- Height: approx. 2.00 – 2.25 m
For larger vehicles (SUVs, vans), a wider or higher solution may be advisable.

How much additional space is required?
Depending on the type of door, some space is required in addition to the opening.
For a sectional door:
- Space above the door (lintel area) → so that the door can move upwards
- Space on the left and right → for the guide rails
- Sufficient depth in the garage → so that the door is below the ceiling
For an up-and-over door:
- Space in front of the garage → the door swings outwards
- Space above the opening → for the mechanism
How to measure correctly (for existing garages)
- Measure the width of the opening at the top, centre and bottom
- Measure the height on the left and right
- Measure the space above the door
- Check the space on the left and right
- Measure the depth of the garage
Important: Measure several times and note any differences.
What should you consider when building a new garage?
When planning a new garage, the dimensions can be chosen optimally from the outset.
Keep the following in mind:
- The increasing width of modern cars
- A possible electric door drive
- Additional doors or windows
- Insulation for attached garages

Frequently asked questions
What is the minimum width for a single garage?
A minimum clear width of approx. 2.50 m is recommended – modern cars are becoming increasingly wider.
Are special sizes possible?
Yes, depending on the type of garage and door system.
Why is the space above the door important?
The door needs space there to move upwards. If there is not enough space, it cannot be installed properly.
Is more space required for an electric drive?
Yes, additional space is required on the ceiling for the drive rail.
Conclusion
The correct dimensions ensure that your garage door operates safely, quietly and reliably. Careful planning prevents problems later on.
