How To Measure A Spa / Hot Tub With Radius Corners or Cut Corners

Standard Square


Rounded Corners Square


Cut Corners Square


Standard Square = Corners come to a 90-degree point. Length & Width required. No additional measurements required.

Rounded Corners Square = Corners have been “rounded off” See instructions for measuring rounded corners (aka radius corners).

Cut Corners Square = Corners have been “cut off”. (Beware, sometimes the cut corners are different sizes!)

Ordering Your Spa Cover

We recommend drawing your spa on paper (including the fold) and measuring all corresponding sides before placing your final order.

Step 1: Choose the “Fold” Option

(If you have a cover lifter we need to know which fold option.)


Step 2: Measure Length and Width of Spa.


Measure Your  Spa – Outer edge to outer edge. (Do NOT measure the water.) Some spas have “Cut Corners” and/or “Radius Corners” (Rounded Corners)


Rounded Corners (aka radius corners) require a Carpenter’s Square (or 2 straight edges) to accurately measure the radius. Center the Square over the rounded corner. Count the number of inches from Point A to Point B (see diagram below).


Depending on the shape of your spa we may require dimensions for all sides, cut corners, rounded corners as well as the dimension in between (see diagram above).

Step 3: Choose a color for your new spa cover.

All colors have been factory treated with mold/ mildew inhibitors & UV resistance. Click here

Step 4: Measure Skirt Length.

Measure from the top of the spa to the bottom of the spa lip.


(Spas installed in ground/ in a deck may NOT require a skirt.)

Step 5: Safety Tie-Downs? How Many?

Options of 2, 4 or None. Note* four (4) Tie-downs are required for the order to be certified as Child Safety Cover.

Step 6: Vapor Proof Barrier (VPB3000) Single or Double Wrap?

Ideal™ Spa Covers come standard with single wrap vapor proof barrier VPB3000. We recommend a double wrap for spas equipped with ozonators.

Step 7: Foam Type?

We offer five (5) foam core options for your spa depending on where you live in the USA.
