# How do I calculate the surface area of my pool?

## How do I calculate the surface area of my pool?

1. FORMULAS. Surface Area (Circle): Radius x Radius x 3.14 (Radius = Diameter / 2) Surface Area (Rectangle/Square): Length x Width.
2. EXAMPLE. A rectangular pool is 50 feet long by 20 feet wide. The shallow end is 3 feet deep and the deep end is 7 feet deep.
3. ANSWERS. Surface Area = 1,800 square feet Volume = 81,000 Gallons.

How big around is a 24 ft pool?

If the diameter of the round pool is 24 ft, then its radius is 12 ft. Since the width of the edging is 2 ft, the radius of the circle for the outside of the edging is 2 ft more than the pool’s radius. So we have two radii. We need the area represented as the ring (mathematicians call this an annulus).

How do I measure the diameter of my pool?

The Diameter is the measurement across the pool from side to side that goes through the very center of the pool. The easiest way to determine if the tape measure is going through the center of the pool is ensure that you are measuring the ‘widest width’ of the pool.

### How many square feet is an average pool?

The average size home swimming pool is roughly 600 square feet, which is pretty darn big if you think about it. If you’re working with limited space but desperately want a refreshing summer escape, a small pool (or mini pool) might be just what the doctor ordered.

How do you use the surface area formula?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

How big of a pool liner do I Need?

You will need two people to make the measurement easier and most accurate. Aboveground pool liners usually have a standard diameter, of 15, 18, 21, 24, 27, 30 or 33 feet. However (!), measure carefully to determine if you can use one of our stock replacement liners for aboveground pools, or if a custom liner is needed.

## How do you measure the radius of a pool liner?

One point of distinction to rectangular pool liners is the radius of the corner. In some cases, the corner can be 90 degrees where the end meets the side, but usually they have a small curve or radius in the corners. To measure a radius corner, you can use a framing square, or two yardsticks, laid perpendicular to each other.

How do you measure the surface area of a swimming pool?

Measure the size of your pool in feet. Use a measuring tape and lay it down one side of the pool and measure the length, ensuring that it is parallel to the edge of the pool. To measure width, begin at a corner of the pool and measure from that corner to the closest corner. Write down both measurements. 4. Calculate Surface Area

What’s the difference between inground and above ground pool liners?

Standard pool liner sizes are usually rectangular for inground pools, while above-ground pools tend to be mostly round. This chart is only meant to give you a general idea of what to expect. As discussed above, other variables will affect the overall cost.
