How to Measure a Hot Tub Cover for a Perfect Custom Fit

If you're in the market for a custom hot tub cover, getting accurate measurements is essential to ensure a snug fit and maximum efficiency. Whether you're replacing an old cover or buying one for a new spa, a well-fitted cover helps retain heat, reduce energy costs, and protect your spa from debris and the elements.

Here’s a simple step-by-step guide on how to properly measure for a hot tub cover, whether you're ordering locally or browsing through hot tub covers Canada online.

Why Accurate Measurements Matter

A custom-fitted spa cover not only looks better—it performs better. Poorly fitting covers allow heat to escape, increasing your energy bill and reducing the life of your hot tub’s components. If you’re ordering a custom hot tub cover, getting your measurements right the first time will save you time, hassle, and money.

What You'll Need

• A flexible measuring tape

• A straight edge or ruler

• A piece of paper and pen to record measurements

• Optional: Your current cover (if it's still intact)

Step-by-Step: How to Measure Your Hot Tub Cover

1. Measure the Length and Width

Start by measuring the outer edge of your spa shell—not the current cover. Use a measuring tape to find the length (the longest side) and the width (the shortest side). Measure in inches and always round up to the nearest half inch.

Example: If your tub measures 84.25" x 78.75", round up to 84.5" x 79".

2. Determine the Corner Radius

Not all hot tubs have square corners. Many feature rounded edges that require a radius measurement. To measure:

• Place a carpenter’s square or two straight edges along the sides of one corner.

• Measure the distance between the point where the curve begins and where the two straight lines meet. This is your corner radius.

Most spas have radii between 2” and 12”, so be precise!

3. Measure the Skirt Length

The skirt is the flap that hangs down from the edge of the cover. It helps keep dirt and debris out and adds insulation. Measure from the bottom of the cover down to the edge of the acrylic shell.

Typical skirt lengths range from 2” to 5”, but can be customized depending on your spa model and preference.

4. Identify the Hinge Location

Determine where the cover folds. Most spa covers are bi-fold and can fold either widthwise or lengthwise. Knowing your hinge orientation is crucial for compatibility with a cover lifter.

5. Note Any Unique Features

If your hot tub has speakers, waterfalls, or raised controls that affect the shape of the cover, be sure to include those details. Most custom hot tub cover suppliers will allow you to upload a diagram or template.

Conclusion

Measuring your hot tub for a new spa cover doesn’t have to be complicated. With just a few tools and careful measurements, you’ll be ready to order a custom cover that fits perfectly and keeps your spa protected all year long.
