Labeled Shade Image
A. Side 1 -- Longest Side (?)
Measure from mounting position to mounting position from corner AB to corner AC. Seams will run parallel to this side. If a single turnbuckle is used at corner AB or AC, subtract 12 to 18 inches from that measurement. If both AB and AC use a turnbuckle at both corners subtract 24 to 36 inches from that measurement. Then enter the results in this field entry.

B. Next Longest Side (?)
Measure from mounting position to mounting position from corner BA to corner BC. If a single turnbuckle is used at corner BA or BC, subtract 12 to 18 inches from that measurement. If both BA and BC use a turnbuckle at both corners subtract 24 to 36 inches from that measurement. Then enter the results in this field entry.

C. Shortest Side (?)
Measure from mounting position to mounting position from corner CB to corner CA. If a single turnbuckle is used at corner CB or CA, subtract 12 to 18 inches from that measurement. If both CB and CA use a turnbuckle at both corners subtract 24 to 36 inches from that measurement. Then enter the results in this field entry.

Hem (?)
Finished width of the hem. Usually 2 inches for a sail shade with a webbing on the edge (less than 299 inches on any side). For a sail shade that is 300 inches or more on any side it will be a wire rope in a sleeve edge. In that scenario the hem allowance should be 3 inches.
