When measuring your spa for a new spa cover, there is one important thing to remember:

IT HAS TO BE LARGE ENOUGH TO FIT!

 When in doubt remember, a slightly oversized cover will fit fine, a slightly undersized cover will not! Covers can be made in one of two styles. The most popular style is to cover only the acrylic shell (measurement A in the below diagram, Fig. 1). The second style is to have the cover extend far enough out to also cover the exposed top rail (measurement B in the below diagram).

There is no difference in spa cover performance either way. It is simply your preference.

In order to make your new cover: We will need both length and width, plus if the corners are round we need the radius and if corners are cut off we need the length of the corner
