Measuring your current spa cover or spa

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.

The distance between the corner of the carpenter's square and the place where it touches the spa (A) equals the radius. The measurement for (B) should be exactly the same.

Measuring a Radius (round corner)

Measuring a radius is not that difficult once you know how (See figure below). The key is to NOT make it too big, this is just the opposite of measuring your spa cover. If you measure the radius too big, it WILL NOT cover the radius corner (See figure below). However, if you measure it too small, it will be just fine. It may hang over a little but there will not be a noticeable difference. When in doubt,take the smaller measurement.
