What is the exact frame dimensions (foot print) for my carport or garage?
The exact dimensions of the frame from the bottom outside frame rail to the opposite outside frame rail are as follows:
If the carport is a 12′ wide x 21′ long the frame will be 12′ outside to outside of the frame, and the length will be 20′ end to end. If an 18’x31′, the width will be 18′ outside to outside, length 30′ end to end and so forth. The extra foot of length comes from the standard 6″ of roof overhang on each end of the structure.
