One of the most important steps when choosing a solar pool cover is measuring different shapes. Whether your pool is rectangular, kidney-shaped, or custom-designed, proper measurement ensures that your cover fits snugly, reducing heat loss and evaporation.
This guide walks you through, with clear instructions and visuals for standard and irregular designs.
Why Accurate Pool Measurement Matters
Solar covers are designed to float on the water’s surface. A poor fit can:
-
Let debris in
-
Decrease heat retention
-
Causes uneven wear on the cover.
To get the most value from your solar cover, measure precisely and choose the right shape or trim to fit.
Tools You’ll Need
-
A tape measure (long enough to span your pool)
-
Notepad or phone to record dimensions
-
(Optional) A helper for large or deep pools
Measuring by Pool Shape
Below are visual examples and step-by-step measurement tips for different pool shapes.
1. Rectangular Pools
Measure:
-
Length (L): End to end
-
Width (W): Side to side at the widest point
Add 2–4 inches extra for trimming.
2. Oval Pools
Measure:
-
Length (L): Longest distance across
-
Width (W): Widest point in the middle
Avoid measuring from curved sections; stick to central axes.
3. Kidney-Shaped Pools
Measure:
-
Length (L): Straight line from top to bottom
-
Width (W): Widest section from left to right
Use a box-style measurement (rectangular bounding box) to cover the whole area.
4. Irregular or Custom Pools
Use the maximum width and length that encloses the pool’s outline. This allows for trimming during installation.
Tips for odd shapes:
-
Always order a larger cover and trim to fit.
-
Mark out the corners or steps when measuring.
-
Include bump-outs or built-in spas if the cover needs to extend over them.
Step-by-Step Measurement Summary
-
Identify your pool shape (refer to diagrams above)
-
Measure the longest point (Length)
-
Measure the widest point (Width)
-
Record extra features (e.g., steps, bump-outs)
-
Round up to allow trimming for a perfect fit.
Should I Order an Oversized Cover?
Yes! It’s always better to order a solar cover slightly larger than needed. Once the cover is in place and softened by the sun, excess material can be trimmed with scissors or a utility knife.
