How To Measure Your Spa Cover

How to Measure your Spa Cover

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 your spa has cut our radius corners be sure to measure them as well. The final measurement required will be the skirt size. The skirt is the small flap that is sewn on to the bottom of the cover, the skirt would cover the acrylic lip that sticks out
from the spas cabinet.

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.

It is always better to make the cover size a little bit bigger than your spa when measuring. If you make a mistake, and measure too small, the cover will not fit properly, will not sit flat and will not hold the heat in.

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

Determine your style and measure per drawing below.

  • A) Square or Rectangle with square corners = Length(A) x Width(B) needed
  • B) Square or Rectangle with one cut corner = Length(A) x Width(B) x  Cut Corner Dimension
  • C) Square or Rectangle with two cut corners =Length(A) x Width(B) x Cut Corner Dimension
  • D) Square or Rectangle with four cut corners = Length(A) x Width(B) x Cut Corner Dimension (C) needed
  • E) Square or Rectangle with rounded corners = Length(A) x Width(B) x Radius Dimension (C) needed
  • F) True Octagon = Length(A) x Width(B) x Dimension of one side (C) needed
  • F) Off-set Octagon = Length(A) x Width(B) x Dimension of each side (8 total)(C) needed
  • Six Sided = Length(A) x Width(B) x Dimension of each side (6 total) (C) needed
  • Ellipse or taper = Must supply a template and/or specific make, year and model of spa
  • G) Round = Diameter (A) needed

How to measure the radius of a curved spa

Method # 1 for determining radius:

To determine the radius of your cover’s corners, take a sheet of paper and trace 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 determining radius: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 place where it touches the spa (A) equals the radius of the curve (B).
