How do I determine how much I need for a standard sized storm door? (Full glass)

Although most residential doors are 3 ft wide and approximately 7 ft tall, we have no way of knowing what size your particular door is. You would need to measure how wide the glass is and then you will choose either 24in or 48-in wide material. The length of the order would be the height of the glass rounded up to the next linear foot. We do have a how to measure link on the website which will give you more information.
