Pool Gallons Calculator

Pool Gallons Calculator

Owning a pool comes with a lot of responsibilities, and one of the most essential tasks is to understand how much water your pool holds. Whether you are adding chemicals, calculating filtration needs, or simply filling it up, knowing the correct volume of water is crucial for pool maintenance.

This guide will walk you through how to use the Pool Gallons Calculator, an online tool designed to help pool owners calculate their pool’s volume, surface area, and water in gallons or liters.


How to Use the Pool Gallons Calculator

Our Pool Gallons Calculator is a simple yet effective tool that allows you to compute the volume of your pool and convert it into various units such as gallons, liters, and cubic feet. Here’s a step-by-step guide on how to use it:

  1. Choose Your Pool Shape
    First, you’ll need to select the shape of your pool. The calculator allows you to choose from three common pool shapes:
    • Rectangular
    • Circular
    • Oval
  2. Enter Pool Dimensions
    Depending on the pool shape you select, the tool will prompt you to input specific dimensions:
    • For Rectangular Pools: Enter the length and width (in feet).
    • For Circular Pools: Enter the diameter (in feet).
    • For Oval Pools: Enter both the length and width (in feet).
  3. Average Depth
    Regardless of the shape, you will be asked to input the average depth of the pool (in feet). This depth is vital for the volume calculation.
  4. Calculate the Pool Gallons
    After filling in all the required fields, click on the Calculate button. The calculator will instantly provide the following results:
    • Volume in Cubic Feet
    • Total Gallons (US gallons)
    • Total Liters
    • Surface Area in Square Feet
  5. Reset the Calculator
    If you need to start over, simply click the Reset button to clear all inputs and results.

Example Calculation

Let’s consider an example to understand how this tool works:

Example 1: Rectangular Pool

  • Shape: Rectangular
  • Length: 20 feet
  • Width: 10 feet
  • Average Depth: 5 feet

After entering the above dimensions, clicking Calculate will provide the following results:

  • Volume: 1,000 cubic feet
  • Total Gallons: 7,480.52 gallons
  • Total Liters: 28,380.99 liters
  • Surface Area: 200 square feet

Example 2: Circular Pool

  • Shape: Circular
  • Diameter: 15 feet
  • Average Depth: 5 feet

After entering these dimensions, you will get:

  • Volume: 1,766.25 cubic feet
  • Total Gallons: 13,213.85 gallons
  • Total Liters: 49,971.74 liters
  • Surface Area: 176.71 square feet

This simple process allows you to calculate the water requirements for your pool quickly and accurately.


Why Is This Calculation Important?

Understanding the volume of your pool is critical for several reasons:

  • Pool Chemicals: To maintain the proper chemical balance, you need to know how much water is in your pool.
  • Pool Pumps & Filtration: The size of your pool will dictate the type of filtration system required.
  • Water Heating: Knowing the volume helps in calculating the energy needed to heat the pool.
  • Pool Covering: Pool covers often come with specific size requirements. Knowing the exact volume will help you choose the right one.

Frequently Asked Questions (FAQs)

  1. What units are used in the Pool Gallons Calculator?
    The calculator provides results in cubic feet, US gallons, liters, and square feet.
  2. Can I use this calculator for any shape of pool?
    The tool supports three common pool shapes: rectangular, circular, and oval.
  3. Do I need to know the exact measurements of my pool?
    While precision is important, approximate measurements can still provide useful results.
  4. What if I don’t know the average depth of my pool?
    You will need to measure the average depth of the pool to get accurate results.
  5. How do I calculate the surface area of my pool?
    The surface area is automatically calculated based on the shape and dimensions you input into the tool.
  6. Can I use the calculator for above-ground pools?
    Yes, the calculator works for both in-ground and above-ground pools.
  7. What’s the difference between gallons and liters?
    Gallons (US) and liters are both units for measuring volume. 1 US gallon = 3.78541 liters.
  8. How do I measure the diameter of a circular pool?
    The diameter is the distance across the widest part of the pool, passing through the center.
  9. Why is the tool asking for both length and width for oval pools?
    Oval pools are measured by their length and width, much like rectangular pools, but with a curved shape.
  10. Can I calculate pool volume without knowing the depth?
    No, the depth is essential for an accurate volume calculation.
  11. What if my pool shape is irregular?
    For irregular shapes, you may need a more complex calculation, but this tool supports standard pool shapes.
  12. Does the calculator include the volume of pool steps or other features?
    No, the tool calculates only the water volume for the main body of the pool.
  13. Can I calculate pool volume in cubic meters instead of feet?
    Currently, the calculator outputs values in cubic feet, gallons, liters, and square feet only.
  14. What should I do if the pool results seem incorrect?
    Double-check the dimensions entered for accuracy. Small errors can lead to big differences in calculations.
  15. Is this tool free to use?
    Yes, the Pool Gallons Calculator is completely free for users.
