Swimming Pool Volume Calculator
Do you want to see other calculation tools?
The calculator we present is a tool to calculate m³ of a pool round, rectangular, or oval. For the calculation, you just have to select the type of pool and enter the indicated lengths to obtain the volume in m³ and liters of water.
In addition to providing the volume of water in cubic meters (m³), it also performs calculations as a pool liters calculator to obtain the unitary capacity of water it can hold.
How does the pool volume calculator work?
The operation of our pool water volume calculator is easy and optimized so you can get the information you need without complications. It has three calculation sections:
1. Calculate round pool volume
- To determine the capacity of a round pool. The user enters the diameter and the average depth of the pool.
- The calculator uses the formula: Volume = Diameter × Depth × 0.785 (Coefficient)
- The result is shown in cubic meters of water (m³) and liters.
For example, if we have a round pool of 4 m in diameter and 1.5 m in average depth. The volume would be 4 m × 1.5 m × 0.785 = 18.84 m³, which is equivalent to 18,840 liters of water.
2. Calculate rectangular or square pool volume
- The user provides the length, width, and average depth.
- The formula used is: Volume = Length × Width × Average Depth
- The volume is calculated and presented in cubic meters (m³) and liters of water.
For example, to calculate the liters of water in a pool, if we have a rectangular pool with a length of 5 m, a width of 3 meters, and 1.5 m of average depth. Its capacity would be 5 m × 3 m × 1.5 m = 22.5 m³, which is equivalent to a water volume of 22,500 liters.
3. Calculate oval pool volume
- Here, the user enters the length, width, and average depth.
- The pool calculator uses the formula: Volume = Length × Width × Average Depth × 0.89 (Coefficient)
- The calculation also offers the result in cubic meters of water (m³) and liters.
For example, if we have an oval pool and want to know how much water fits in a pool with a length of 5 m, a width of 3 meters, and 1.5 m of average depth. The volume would be 5 m × 3 m × 1.5 m = 22.5 m³, which is equivalent to a capacity of 22,500 liters.
Each section provides example values to facilitate use, and the result shows the volume in two units: cubic meters and liters. The pool calculator is designed to adjust specifications according to type.

How to calculate the volume of a sloped pool?
To calculate the capacity of a pool with a sloped bottom, the pool is divided into two volumes to simplify the calculation and then added together. As indicated in the following image.
Even if we have steps, their volume is usually very small compared to the size of the pool. If the pool is more complex, the same procedure of dividing into sections and adding them together is usually followed.
Remember that if it is a prefabricated pool, the instructions include the capacity in liters of the pool
How to calculate the surface and capacity of a pool with a strange shape?
The shapes of ponds and pools can be very varied; from basic ones like circular, rectangular, triangular, and oval, there are even kidney-shaped or football stadium-shaped.
When the surface geometry is more complex, we can use the following formulas to calculate the square meters of a pool (surface) and then multiply by the depth to obtain the volume and liters.
We have already seen some mathematical calculations. The following image is a summary including strange shapes:
- Calculate triangular pool volume. The formula is: [(L x W) /2)] x Average Depth
- Calculate kidney-shaped pool volume. The formula is: [(A+B)×L×0.45] x Average Depth
- Calculate football field-shaped pool volume. The formula is: [(L×W)+(3.14×R2)][(L×W)+(3.14×R2)] x Average Depth
Remember that if the surface has many curves, you will have to be patient and do the calculations by sections to get the total. As complementary guides, we recommend two links:
- Information for the treatment and maintenance of pools, ponds, and pools.
- A PDF on the calculation and sizing of pool equipment (filtration, pumping, built-in, sanitizers, and heating)
Frequently asked questions about calculating pool volume – FAQ
What do I need to measure my pool and perform the calculations?
Generally, a tape measure, a calculator, and paper and pencil to write down will suffice.
How is the volume of a rectangular pool calculated?
The volume of a rectangular pool is calculated by multiplying the length by the width and then by the average depth. The formula is Volume = Length × Width × Average Depth.
How is the volume of a circular pool calculated?
For a circular-shaped pool, the volume can be obtained using the formula: Volume = π × (Radius)² × Depth. In this case, π is taken as 3.1416, and the radius is defined as half the diameter of the pool.
What is the difference between volume and capacity of a pool?
The term volume refers to the space occupied by the water in the pool. Capacity refers to the amount of water needed to fill the space, usually expressed in liters or gallons.
What units of measurement are used for the volume of a pool?
It is clarified that the volume is measured in cubic meters (m³) and can be converted to liters by multiplying by 1000.
How are cubic meters converted to liters?
One cubic meter (m³) equals 1,000 liters. To convert from cubic meters to liters, multiply the volume m³ by 1,000. For example, if I have a pool that has 15 m³, the calculation would be 15 × 1,000 = 15,000 liters.
How is the depth of a pool with a sloped bottom measured?
The depth is measured at the shallowest point and the deepest point, and the average of these two measurements is calculated. This average is used to apply the volume formulas.
What units are used for the calculation of pool volume?
The most common units are cubic meters (m³) and liters in the metric system, while in the imperial system, cubic feet or gallons are used.
How does the shape of the pool affect the volume calculation?
The shape of the pool determines the choice of the appropriate formula. Pools with regular shapes, such as rectangular or circular, allow for simple formulas. More complex shapes require dividing the pool into simpler sections.
What aspects should be considered if the pool has steps, benches, or different depths?
For pools with steps, stairs, or areas with different depths, it is common to treat each section separately, calculating the volume individually and then adding the volumes to obtain the total.
