barngarage
I have an existing structure that is currently a single car that i'd like to convert to a two car garage; it measures 16×20 feet. The two garage doors would be mounted on the longest side (20 feet).
Would 16 feet be sufficient to back into and be ok? Has anyone ever seen or attempted a 16×20 two car garage?
These look nice
You could probably build a simpler version pretty cheap.
Also if the doors are large enough, and you are ambitious enough you could put a smaller "man" door in one of the doors. That way when you go in and out you don't have to open the large doors, but you still have the large doors for getting large projects/lawn tractor in and out.
One of the custom door manufacturers should be able to make you something. Yes, it's not a typical application being that small, but there's no major issues in the design. Doors are assembled from panels, so they can select the right size and quantity. Track frequently has to be cut down to fit anyways. Custom springs are no big deal (a surprising percentage of what's out there is custom).
However, you're not going to be able to walk into a local big box hardware place and pickup off the shelf components to DIY.

The ideal size will vary with the size of the vehicles you drive. There is a vast difference in the space required to comfortably open the doors and exit a Mini Cooper and a full size pick-up. I live in an older home with a 2 car garage built in the 1920's. The inside dimensions are 18' by 18'. To fit 2 cars (06 and 08 Chevrolet Impala) in it, the one on the left must be backed in and the one on the right driven in. Exiting the vehicle requires caution to keep the doors from dinging each other. Opening the passenger doors is impossible as there is less than a foot of clearance to the wall. Doing any kind of repair or maintenance in the garage is impossible with both cars inside.
