What dimensions should I measure when buying a door?

According to our specialists, you need to measure almost every section of your garage and its opening. This includes headroom, sideroom, depth, width, and height. The material from which your new door will be made of also needs to be taken into consideration. Wood and aluminum will be lighter than steel, for example, and will require less horsepower to operate smoothly. This affects whether you will require a new opener or not.
