There are many shapes to spas and spa covers.  When measuring your spa cover, be sure to measure from seam to seam on the cover.  
The spa company that you purchased your spa from may be able to give you all of the dimensions of your spa cover.  Be sure to check with them.  This could save you some time.

Measuring the SKIRT of Your Spa Cover
The FLAP that hangs from the bottom of the Spa Cover is considered the SKIRT.  There are two panels.
The first measurement will be taken from the top seam of the skirt to the middle seam of the SKIRT.
The second measurement will be taken from the middle seam of the skirt to the very bottom of the skirt.

Measuring the RADIUS for Rounded Corner Shaped Spa Covers
Measuring the radius is not as difficult as it may appear.  The diagram will show you the easiest way to measure the radius.  A carpenter square can help.  The dimension that is necessary is from the start of the bend to the imaginary point of the square if the spa cover were square.  The smaller the radius is the more square the corner of the spa cover is.

Square or Rectangle

A radius on four corners
Measure radius "C": extend straight lines indicated in red by laying straightedges against the sides of the spa. Measure from point "Y" to point "Z".

Square cover
The square Spa Cover is the easiest to measure   Measure the outside lip to lip or seam to seam. The only other measurement you will need is the skirt length.

Rectangle cover
Similar to the square spa cover, but make sure you request the fold direction you require. Most companies will by default cut the longest of the two sides in half.

Square or Rectangle with Radius Corners
Follow the same directions for the square and rectangle spa cover procedure and add the radius measurement.

Round
Round spa covers are also easy to measure. Measure the lip to lip measurement. Measure your old spa cover across the seam.  The only other measurement you will need is the skirt length.

Octagon
Measure from lip to lip for the Octagon Spa Cover.  Your will need to measure one panel of the octagon from point to point. The only other measurement you will need is the skirt length.

Ellipse or Special Shapes
Most of these covers will require a template provided by you to complete your cover properly. This would include spas with speaker bumps, waterfalls, or cut outs for rails or controls.
