Carport Measuring Guide

To get the correct width valance cover tarp, you must measure the distance marked ‘C’ in the diagram

B = Width of End Panel Needed
C = Width of Top Cover Needed

If C = 11 then the valance roof is 11 feet wide
If C = 12 then the valance roof is 12 feet wide
If C = 14 then the valance roof is 14 feet wide
If C = 16 then the valance roof is 16 feet wide
If C = 18 then the valance roof is 18 feet wide

Example: If C=12 and frame length=20, you will need a 12×20 valance top cover.

How to Measure Roof Cover Width

For correct roof cover width (item C in diagram above), use a tape measure to find the distance between the middle of the bottom horizontal roof pole (photo 2 below) to the middle of the top horizontal roof peak pole (photo 3 below), then double this number to get the proper roof cover width.

Measure Carefully

It is very important to measure accurately to determine the correct size for a replacement carport cover. All carport roofs take a larger size cover than the actual carport width.

For example: A 10 x 20 carport uses a 12 x 20 cover in most cases because the roof has greater width than the carport width. However, there are some cases where a carport will require an odd size cover, such as a 10 x 20 carport that needs an 11 x 20 cover. This is why measuring is very important.

Please see the diagram above and photos below for proper measuring guidelines.
