Measure Correctly
State measurements in inches, not feet. Round up length and width to the nearest inch. A cover that is slightly larger (even 1-2 inches) than the spa will fit and function just fine, but a cover that is significantly too small may suffer some loss in heat retention. Double-check your measurements for accuracy that is significantly too small may suffer some loss in heat retention. Double-check your measurements for accuracy
Take Measurements
CUT CORNERS SPA COVER
The center hinge always cuts the “A” dimension in half, determining fold
orientation. Take measurements in inches (not feet) and round up or down as
directed. (This spa has 4 cut corners. If your spa has 8 equal-length sides,
choose the Equal Octagon shape instead).
Measure Skirt Length
The skirt is the overhanging flap, extending from the bottom edge of the spa cover (which is the top of the spa’s rim). A common length is 5”. For acrylic spas, the skirt should cover the exposed lip of the shell, plus about 1/2” more, rounded up to even inches. The minimum skirt length is 2”. Covers can also be made with no skirt, in which case enter “0” for skirt length.

Measure Strap Length
The strap length is measured from the bottom of the cover (which is the top of
the spa’s rim) to the top of the latch, as illustrated. In our example, the
straps are 9” long, extending 4” below the skirt. The strap must extend at
least 2” or more below the bottom edge of the skirt.
- Do not measure from the bottom edge of the skirt
- Do not include latch in measurement.
Note : Straps are required for safety. Due to production variations,
strap location around the spa cannot be guaranteed by any cover maker. For
this reason, new latches and mounting hardware are provided.
