How do I measure my pool for a new liner?
Question:I am replacing my pool liner and it is sloped at the botom from 3-7 feet, and slopes in the deep end on the sides too, how do I measure this for a replacement, or will a liner stretch and mold into position?
Answers:
You'd best consult with whoever you're buying the pool liner from to get specifics. This is not an easy job, generally should be done by a professional, especially if it's an in-ground pool. You are liable to run into difficulties that you won't know how to handle.
See the following pictorial presentation, it will give you some good ideas

Vinyl does have stretchability but there's more to installing these liners than meets the eye. Measuring with a flexible tape (requires 2 persons) will allow you to accommodate curves and get some fairly exact measurements. Draw a diagram of the pool so that the measurements from one point to another can be shown.
take your width , length, and depth measurements to your local pool suppy house and they should be able to advise you. it sounds like you may need an expandable liner
I would draw a diagram of the pool as if looking at it from the side. (height * Length), write down width somewhere.
I would mark the bottom at three points, such as 12', 8' and 2 '
I would run a line to connect to the three point, this is the slope of the bottom of my pool
Now from the 12' go up about 2 feet and draw a staight line directly across the pool so that now I have a pool with a flat bottom and a triangel
Now I can calculate the volume for the pool, then do the volume of a triangular shape and add them up - this is the total volume I am looking at for this pool - this will be the measure you'll need.
You see, all you are doing is dividing what you have into the rectangle of a pool, and the triangle so that each's area can be calculated - you are not changing what already exist.
The points are required so you can get the correct slop of the Triangle, in this case.
You'll want to use two formulas though,
Volume of a rectangle, and volume of a Triangle, which are :
Rectangle - v :L(ength) * W(idth) * H(eight)
1. Area of a triangle : 1/2base(height)
2 Volume of Trianglular shape - Area of Triangle ( Width)
Remember, for complex shapes draw them out and break them down to simpler geometric shapes - then begin the calculations.
