Springs are the main operation and function of your door. Without springs your door wouldn't budge or move. There are typically two different types of springs that are used in todays doors.

Your one car, one spring set up garage door normally comes with only one spring, which sizes consist of a 8'x7', 8'x8', 9'x7' and a 9'x8' standard size door. Then your two car, two spring set up consists of a 16'x7', 16'x8', 18'x7' and a 18'x8' standard door. In some cases there may be a 20'x7' or 20'x8' garage door which is special ordered.
