How to measure your pool
Measure your pool from a satellite map to find its surface area in square feet. Use it to size a pool cover, estimate chemicals, compare liner quotes, or simply know your pool’s dimensions.
Rectangular, kidney-shaped, oval, or free-form pools can all be measured by tracing the water’s edge.

Step by step
Search your address
Search your address and zoom in until the pool fills most of the screen.
Trace the water’s edge
Trace the inside edge of the water. Add extra points for curved or free-form pools, then close the shape.

The measured square footage appears instantly and can be used for covers, liners, maintenance, and planning.
What you can do with your pool measurement
Once you know your pool’s surface area, you can:
- Size a solar cover or safety cover
- Compare liner replacement quotes
- Estimate chemical treatments
- Plan surrounding decking or landscaping
- Keep a record of your pool’s dimensions
Common pool projects that start with a measurement
A single pool measurement is the starting point for projects like:
- Solar covers
- Safety covers
- Automatic covers
- Pool liners
- Chemical planning
- Deck replacement
- Pool remodeling
Surface area, not volume
This tool measures your pool’s surface area in square feet. Pool volume (gallons) also depends on average depth, which can’t be determined from overhead imagery alone.
FAQ
Frequently asked questions
How do I measure my pool from a map?
Search your address, trace the water’s edge on the satellite image, and read the surface area in square feet.
What size solar or safety cover do I need?
Covers are sized to the pool’s surface area and shape — match your measured square footage to the cover’s listed size.
Does this give my pool’s volume in gallons?
No — tracing gives the surface area. Volume also needs the average depth, which you can’t read from a top-down photo.
Can I measure an irregular-shaped pool?
Yes. Add more points while tracing curved edges to closely match the pool’s shape for the most accurate measurement.
Should I trace the water or the concrete deck?
Trace the water’s edge if you’re measuring the pool itself. Measure the surrounding deck as a separate area if you need its square footage.
