Of all the pool shapes, a freeform is the most difficult to measure. To get an accurate measurement we recommend using the A - B point to point method. It involves measuring a series of points around the perimeter of the pool from two fixed points roughly 5 - 10 feet from the pool. This method is versatile and can be used for any size or shape of pool. If it’s done right and all of the measurements are recorded correctly, it gives the designers a very accurate layout of the pool’s perimeter. If you use this method you can measure any pool that comes your way.
