It is best if you measure your existing cover and not your spa. In order to get the proper length and width, measure across the seam, then perpendicular to that. If you do not have a cover to measure from, then you must measure all the outside dimensions of the spa. The cover has a 2" flap around the edges of the spa called a skirt. The skirt must easily sit over the edges of the spa, with a little room to spare.

 

Spas come in a variety of "standard" shapes. Determining your units shape will help
you order the proper cover.

Method #1 -Determining radius: To determine the radius of your cover's corners, take a sheet of paper and tr{b}ace around one of the curved corners of the cover. You will get a curved line similar to those shown at the left. Remove the paper and complete the circle. You can do this freehand. Then measure across the middle of the circle you drew, and divide by 2.
Method # 2 for determing radius: Another way to measure the radius is by placing a carpenter's square on the outside of your spa. The distance between the corner of the carpenter's square and the {a}place where it touches the spa (A) equals the radius of the curve (B).
