How To Measure For Your
Spa Cover - Part 2
Shapes and Radius Corners
|How To Measure A Hot
Tub Spa Cover
Spas come in a variety of "standard" shapes. Determining your unit's shape will help you order the proper cover.
Square = L x W
Rectangle = L x W
Square with cut corners = L x W x Cut Corner Dimension
Rectangle with cut corners = L x W x Cut Corner Dimension
Square with rounded corners = L x W x Radius Dimension (See Radius below)
Rectangle with rounded corners = L x W x Radius Dimension (See Radius below)
Square with one cut corner = L x W x Cut Corner Dimension - must note which corner is cut and orientation of fold - must supply drawing to us !
Square with two cut corners = L x W x Cut Corner Dimension - must note which corners are cut and orientation of fold - must supply drawing to us !
Ellipse or taper = Must supply template to us.
True Octagon = L x W x Dimension of one side
Off-set Octagon = L x W x Dimension of each side ( 8 total )
Six Sided = L x W x Dimension of each side ( 6 total )
Round = Diameter
Fold = The length across the seam
The term "radius corners" scares a lot of people. It brings back bad memories of high school math class!
Many spa covers have rounded corners. In order for us to make you a cover, we must know how rounded they are. This is determined by figuring out their radius dimension.
The diameter of a circle is the measurement across the center. The radius of a circle is half of its diameter. Very simple.
Method # 1 for determining radius: We do not recommend using this method unless absolutely necessary

Remember, if you are a little too big, the cover will still fit (and work) fine. However if you are even the slightest bit too small, the cover will not sit properly on the spa. If you have to guess one way or the other, go bigger (order the cover a little bigger...order with a smaller radius). The smaller the radius measurement, the 'bigger' the cover will be (more material). The larger the radius, the more the cover will be "cut off" (less material).
For example, take a look at the photo to the left. That shows the spa touching the carpenter's square at 6 1/2 inches. If you ordered a 6 1/2 inch radius cover, the cover would either be a little too small, or fit very snuggly. If you ordered it as a 6 inch radius, it would be a little bit bigger, the skirt will hang down nicely, and you would not have to struggle to get the cover on. You can't go wrong with the cover being a little bit bigger (smaller radius measurement).
