How to Measure Hot Tub Cover

Hot tub covers are an essential accessory for anyone who owns a hot tub. They not only provide protection for your hot tub, but also help to keep the water clean and warm. However, finding the right size cover can be challenging if you don’t know to measure hot tub cover correctly.

How to Measure Hot Tub Cover

When it comes to owning a hot tub, one of the most important factors is ensuring that you have an appropriate cover for it. Not only does a cover protect your hot tub from debris and harsh weather conditions, but it can also help keep your energy costs down by insulating the water.

However, in order to reap these benefits, it is essential that your hot tub cover fits properly. You can find step-by-step instructions on how to measure hot tub cover in this blog article.

Tools You Will Need

  • Measuring tape
  • Paper and pencil
  • Level or ruler
  • String or cord
  • Scissors or knife
  • Calculator (optional)
  • Straight edge (optional)
  • Angle finder (optional)
  • Camera (optional)
  • Computer with internet access (optional)

Hot tub covers come in a variety of shapes and sizes. If your hot tub cover has become weathered and needs to be replaced, it is important to measure it correctly before ordering a new one. Measuring your hot tub cover accurately is crucial so that you can ensure the perfect fit.

Step-by-step Instructions for How to Measure Hot Tub Cover

Step 1: Inspect Your Hot Tub Cover

Take a close look at your hot tub cover and make sure it is in good condition. If there are any tears, holes or other damage, you may need to replace the whole thing instead of just measuring for a new one.

Step 2: Measure from the Inside Edge

Start by measuring from the inside edge of your hot tub. This will give you the most accurate measurement and ensure that your new cover fits properly. Using your measuring tape, measure from one corner of the hot tub to the opposite corner. Make sure to pull the measuring tape tight for an accurate measurement.

Step 3: Measure the Radius

If your hot tub has rounded corners, you will need to measure the radius instead of just the distance between corners. To do this, hold one end of your measuring tape at the center of the curve and measure to the outside edge. Repeat this step for the other two corners of your hot tub, measuring from corner to corner. Write down all three measurements.

Step 4: Calculate the Average

To ensure the most accurate measurement, you will need to calculate the average of all three measurements. To do this, add all three numbers together and divide by 3. Next, measure the lip or flange around your hot tub. This is important because some covers require a larger lip for proper fit.

Step 5: Measure the Slope

Measure the slope of your hot tub cover by placing a level or ruler across it. This will help ensure the new cover fits correctly. If you are ordering your new hot tub cover online, take a picture of your hot tub and its measurements to ensure you order the correct size and style.

Ensure the New Cover Fits Correctly

Finally, it’s time to order your new hot tub cover! Use the measurements you have taken to find the perfect fit and style for your hot tub. Make sure to double check all measurements before placing your order.

Safety Tips for How to Measure Hot Tub Cover

  1. Before you start measuring your hot tub cover, it’s essential to disconnect any power sources that are connected to your hot tub. This includes turning off the electricity supply and unplugging any electrical components such as heaters or pumps.
  2. When handling a heavy object like a hot tub cover, it’s crucial to wear protective gear to prevent any injuries. This can include gloves, safety glasses, and closed-toe shoes.
  3. It’s also essential to have someone help you when measuring your hot tub cover. Hot tub covers can be heavy and awkward to handle alone, so having an extra set of hands can make the process much more manageable and safer.
  4. Be careful when removing your hot tub cover or any other accessories around your hot tub. Ensure that you have a firm footing and take extra precautions if the surface is wet or slippery.
  5. When measuring your hot tub cover, make sure to use appropriate measuring tools such as a tape measure or ruler. This will ensure accurate measurements and prevent any mistakes in sizing.
  6. It’s crucial to note down all measurements accurately and double-check them before purchasing a new hot tub cover. This will save you time, money, and frustration in the long run.
  7. Finally, always follow manufacturer’s instructions or seek professional help if you are unsure about how to measure your hot tub cover properly. This will ensure that you get the correct measurements and purchase a cover that fits perfectly.
Get the Correct Measurements

In addition to these safety tips, it’s also important to know the steps for measuring a hot tub cover correctly. First, remove any existing covers from your hot tub and clean the surface area thoroughly. Then, measure both the length and width of your hot tub, including any rounded corners or edges.

Is There a Specific Method for Measuring a Hot Tub Cover?

Hot tub covers are an essential part of maintaining your hot tub and keeping it in good condition. They not only protect the water from debris, but also help to insulate the tub, keeping it warm and reducing energy costs. However, when it comes time to replace or purchase a new cover, many people may wonder how exactly they should measure their hot tub cover.

The good news is, there is no right or wrong way to measure a hot tub cover. As long as you have the correct measurements and order from a reputable company, your new cover should fit perfectly. Here are some general steps for measuring your hot tub cover:

  • Start by Removing Your Old Cover: Before taking any measurements, it’s important to remove your current hot tub cover. This will ensure that you get accurate measurements and won’t have to make any adjustments later on.
  • Measure the Width: The width of your hot tub cover should be measured from one outside edge to the other, across the center of the tub. It’s important to measure this at its widest point, which may not necessarily be at the top or bottom of the tub.
  • Measure the Length: Next, measure the length of your hot tub cover from one outside edge to the other, across the center. Again, make sure you are measuring at its longest point.
  • Record Measurements: Once you have these two measurements, record them in inches. These are the most important measurements that you will need when ordering a new hot tub cover.
  • Check for Any Variations: Depending on the shape and style of your hot tub, you may also need to measure other areas such as the corner radius or lip length. Be sure to check with the manufacturer or retailer to see if these measurements are necessary for your specific hot tub model.
  • Consider Thickness and Taper: When ordering a new hot tub cover, it’s also important to consider the thickness and taper. The thickness can vary from 3 inches to 6 inches, depending on your personal preference and climate conditions. Taper is the slope of the cover, which helps with water runoff and prevents pooling.
Ordering a New Hot Tub Cover

Once you have all of these measurements in hand, you are ready to order a new hot tub cover! It’s always a good idea to double check your measurements and consult with the manufacturer or retailer before placing your order, just to be sure you are getting the right size for your hot tub.

Are There Any Common Mistakes to Avoid When Measuring a Hot Tub Cover?

When it comes to measuring a hot tub cover, there are certain common mistakes that should be avoided in order to ensure an accurate measurement. Here are some of the most common mistakes and how you can avoid them.

1. Not Measuring Both Length and Width

One of the most important steps when measuring a hot tub cover is to measure both its length and width. Some people only measure one of these dimensions, leading to an ill-fitted cover. To avoid this mistake, make sure you have the correct measurements for both length and width.

2. Not Measuring at the Widest Point

Another common mistake is not measuring at the widest point of the hot tub. It’s important to measure from edge-to-edge rather than just along one side. This ensures that the cover will fit snugly and properly over the hot tub.

3. Not Allowing for Overhang

Many hot tub covers are designed to have an overhang of a few inches to provide better insulation and protection from debris. However, some people forget to take this into account when measuring, resulting in a cover that is too small for their hot tub. Be sure to measure with the overhang in mind.

4. Not Taking into Account Sloped Sides

Some hot tubs have sloped sides, which can be tricky to measure. Make sure you take this into account when measuring and adjust accordingly. You may need to measure at multiple points along the sloped edge to get an accurate measurement.

Measuring and Adjust Accordingly

5. Not Double-Checking Measurements

Lastly, always double-check your measurements before ordering a hot tub cover. It’s much better to catch any mistakes now rather than receiving a cover that doesn’t fit and having to reorder or make adjustments. Taking the extra time to double-check can save you a lot of hassle in the long run.

By avoiding these common mistakes, you can ensure an accurate measurement for your hot tub cover and avoid any issues with ill-fitting covers. So make sure to take your time and measure carefully before ordering a new cover, and always double-check your measurements to ensure a perfect fit.

Are There Any Special Considerations for Measuring a Round or Oval Hot Tub Cover?

Round and oval hot tubs are becoming increasingly popular thanks to their unique shape and ability to fit into smaller spaces. However, if you own a round or oval hot tub, you may be wondering if there are any special considerations for measuring your hot tub cover. The answer is yes! While the process is similar to measuring a square or rectangular cover, there are a few key differences to note.

First and foremost, it’s important to measure the exact shape of your round or oval hot tub. This includes measuring the diameter or width at its widest point, as well as the length from one side to the other. The measurements should be taken from edges of your hot tub, rather than any existing cover or frame that may be in place.

Measurements Should Be Taken From Edges

In addition, it’s important to note that round and oval hot tub covers typically have a slight overhang. This means that the cover will be slightly larger than the actual dimensions of your hot tub.


In conclusion, measuring a round or oval hot tub cover may require a bit more attention to detail, but it’s not too different from measuring a square or rectangular cover. By accurately measuring the exact shape of your hot tub and factoring in the slight overhang, you can ensure a perfect fit for your new cover.

And with proper measurements, you’ll be able to find the right size cover to protect your hot tub and keep it in top condition. I hope this article has been beneficial for learning how to measure hot tub cover. Make Sure the precautionary measures are followed chronologically.
