Because garage doors are usually sized to snugly fit the dimensions of the garage itself making the door larger usually means making the garage larger.
Making garage door opening taller.
If you have the room on the back side of your garage you can make your garage into what is called a jack jill garage.
To put it into perspective if the garage door is let s say 8ft tall make the height of your opening 8ft 1 5 inches tall.
I removed some siding and and re did the trim on the top of the door and then recovered every thing with aluminum and installed new rubber garage door sill around the opening.
The height of the rough opening must be 1 5 inches taller than the garage door you intend to buy.
If you are lucky it s in good shape and either made from 2x12 s or even better a glulam beam.
That is the side where your truck is to go you can build out on the back side.
Easy to do and it can solve alot of problems.
That made my door height two inches taller.
Usually 4 or 8 feet.
