HOW DO I MEASURE THE SIZE OF MY AWNING?
Size is measured as the distance from the center line of one awning arm to the center line of the other arm. This measurement is in whole foot increments. The actual fabric will measure approximately 10″ less.
If the measurement of the distance between center line of arms is 16ft, then you will need a 16ft awning fabric. For a 16ft awning, the actual width of the fabric is between 15’1″ and 15’3″.
