1. Begin with a freehand sketch indicating inside pool dimensions. Include deck area, planters and any obstructions within 3’ of the waterline. A photo of the pool is needed when rocks, waterfalls, raised walls, spas or anything out of the ordinary exists.

2.Establish two points, "A-B" with "A" on the left as shown. "A-B" line must be at least 3’ away from the pool and 2/3 the length of the pool; 20’-25’ is typical (show this on the sketch). To mark "A-B" points on deck - use chalk marks, on ground - use stakes in the dirt.

NOTE: The "A-B" line must never cross the pool line and should be approximately 3’ away from the pool at the closest point (4’ to 5’ away for pools over 44’ long).

3. Using chalk, mark and number points along the inside edge of the pool at approximately 3’ intervals. Number all corner points, ladders, handrails, grabrails, slide legs, rocks, spillways, spa walls separating spa and pool, fill spout and dive stand. 1’ to 2’ intervals should be used in small or tight radius areas and raised wall areas. At least 3 points along straight walls.

4. Measurements are now taken from point "A" to point #1, then point #2, and all the way around the pool. Then measure from point "B" to same point #1 and then #2, as you did for point "A". Measurements are listed in column format as shown.

5. Take measurements between 2 known points to determine the length and width of the pool. Additional measurements for difficult pools are suggested. Cross dimensions to any raised beam obstacles are also recommended.
