Measure the backroom the distance from the garage door opening to the back wall of the garage.
How tall is the average garage door.
Recreational vehicles loom taller than the average suv and as such need extra height built into the garage and the garage door.
You can get a custom height for an additional cost.
The standard size for an rv garage door is 8 to 9 feet tall as opposed to 7 with a width of at least 16 feet.
A rv garage door widht and height depends on the type of rv you have.
On average it should be aroudn 12 14 feet in width and 14 feet in height.
Doors made for two cars can be as little as 14 feet wide 4 3 meters but are more commonly 15 or 16 feet wide 4 6 or 4 9 meters.
The standard garage door height is 7 feet 2 1 meters but an 8 foot 2 4 meter height is also available.
In the event you are adding a door to a garage without one you will need to carefully measure the width and height of the opening.
Buildng own garage for rv saves on storage costs.
A garage will need backroom that equals the door height plus 18 inches and possibly more based on the installation of an automatic garage door opener.
