How to Measure for a New Pool Cover

A pool cover protects your investment by keeping out debris, reducing evaporation, and enhancing safety. But to get the most out of a cover, it needs to fit properly. An incorrectly sized pool cover can sag, tear, or fail to protect your pool effectively. Learning how to measure your pool correctly ensures you get the best coverage, whether you are purchasing a standard or custom cover.

Why Accurate Pool Measurements Matter

Getting accurate dimensions is the foundation of a good pool cover fit. When the cover matches your pool shape and size:

• Safety improves because the cover stays secure without gaps.

• Maintenance is easier as debris stays out of the water.

• Energy savings increase since heat retention and chemical balance are maintained.

• Longevity of the cover is extended because it fits without unnecessary strain.

Tools You Need for Measuring

Before starting, gather the following tools:

• A long measuring tape (at least as long as your pool’s width)

• A notepad and pencil for recording measurements

• A helper if your pool is large or irregularly shaped

• A straight edge or chalk line for complex pool shapes

Step-by-Step Guide to Measuring Your Pool

Different pool shapes require slightly different approaches. Here’s how to measure based on your pool design:

1. Rectangular Pools

1. Measure the length from one end to the other.

2. Measure the width across the pool at the widest point.

3. Record both measurements and round up to the nearest half foot.

2. Oval Pools

1. Measure the longest length through the center.

2. Measure the widest width at the midpoint.

3. Round your numbers up slightly to ensure proper fit.

3. Round Pools

1. Measure the diameter by finding the distance across the center.

2. Double-check by measuring from multiple points to confirm accuracy.

4. Freeform or Irregular Pools

1. Measure the widest length and widest width.

2. Use a chalk line or string to trace curves.

3. Take multiple reference points and provide them to the cover manufacturer.

Measuring for In-Ground vs. Above-Ground Pools

• In-Ground Pools: Often require custom measurements if irregularly shaped. Ensure coping and decking are included in your notes.

• Above-Ground Pools: Typically come in standard round or oval sizes, so accurate diameter and height are key.

Factoring in Pool Features

Do not forget to account for features that affect fit:

• Steps and ladders may require extensions or cutouts.

• Diving boards and slides need additional clearance.

• Raised walls or spillovers should be noted for custom covers.

Tips for Getting the Best Fit

• Always measure twice to confirm accuracy.

• Round up measurements instead of rounding down to avoid a cover that is too small.

• Consult with the manufacturer if your pool has unusual features.

• Take photos of your pool layout to share with the cover supplier for added precision.

Common Mistakes to Avoid

• Guessing pool dimensions instead of measuring

• Forgetting to measure over steps or ledges

• Providing only one measurement for irregular pools

• Not accounting for deck or coping space

When to Consider a Custom Pool Cover

If your pool is kidney-shaped, freeform, or includes multiple built-in features, a custom pool cover is the best option. Custom covers are designed to fit unique layouts, ensuring complete coverage and a professional finish.

Caring for Your Pool Cover After Installation

Once you have the perfect fit, proper care ensures your cover lasts:

• Remove debris regularly to prevent strain.

• Check for rips or wear during the season.

• Store the cover in a dry place when not in use.

• Follow manufacturer cleaning recommendations.

A well-measured pool cover not only protects your pool but also saves time and money in maintenance. With accurate measurements, you can feel confident that your investment is well protected and your pool stays in top condition year-round.
