How do I choose the right size garage door for a single or double bay garage?

This typically isn't much of a choice. Garage door size is set by your existing opening, unless you're remodeling or building new. Standard single doors run 8 or 9 feet wide by 7 or 8 feet tall, and standard double doors run 16 feet wide with the same height options. Our technicians can help you pick the right size if you're starting from scratch.
