More measuring tips:
• Measure both the spa and the old cover, if possible. If they differ, use the measurement from the spa.
• Make sure the measurements are big enough. It is okay for the cover to be big. It still does its job. However, a cover too small will never do the job it is supposed to.
• Measure all sides of the spa. We have computation formulas to double check the dimensions. They work a lot better when we have all the dimensions.
• Measure the overall length and width of the spa.
• Always error on the side of adding surface area to the cover. Round overall dimensions up to the next whole number in inches. Round down any dimensions of cut corners or radius corners.
• Be careful when representing the dimensions on the order forms making sure that the desired hinge direction is drawn.
• For rounded corners, check out the picture to the right. |

Above is an illustration of the best way to measure the radius. With a carpenter’s framing square, you need to “square” out the corner. What will result is the framing square representing where the corner would be if the corners were not rounded.
As illustrated above, after “squaring” out the corner, measure along the framing square the distance from the inverse midpoint (A) and the end beginning of the rounded corner (B).
