Mattress Protector Size Chart

Mattress Protector Size Chart

Choosing the right mattress protector starts with understanding the six standard mattress sizes. Here is a handy mattress protector size chart covering dimensions for all the common mattress types:

Mattress Size

Dimensions (Inches)

Best Suited For


39" x 75"

Kids, teens

Twin XL

39" x 80"

Teens, tall adults


54" x 75"

Single adults


60" x 80"



76" x 80"

Couples who like space

California King

72" x 84"

Tall couples

This size chart provides the length, width, and recommended sleeper size for each mattress type. Make note of your specific mattress dimensions to ensure you get an accurately sized protector.

The most popular mattress sizes in Canada are:

  • Queen - Ideal for single adults and couples. Provides ample room to stretch out.
  • King - Made for couples who like extra spaciousness for sleeping.
  • Twin/Twin XL - Great for kids and teens. Twin XL suits tall teenagers.

Now that you know the basic mattress protector dimensions, let's go over how to accurately measure your bed.

How to Measure Your Mattress

Taking precise measurements of your mattress ensures you order the right protector size. Follow these steps:

  • Use a soft measuring tape and lay it across the longest length of the mattress. Note the measurement in inches.
  • Next, measure the width of the mattress from edge to edge in inches.
  • Finally, measure the mattress depth. This is especially important for extra thick pillowtop or euro style mattresses.
  • Record all the length, width, and depth figures. Compare them to a mattress size chart.
  • For added accuracy, repeat the measurements a second time.

Other tips for measuring mattress size:

  • Include any thick mattress topper or pad in your measurement if you plan to keep using it.
  • For platform beds, measure inside the wooden frame as the protector fits inside.
  • Round your measurement to the nearest whole inch.
  • If in between sizes, we recommend sizing up to the next size protector.

Accurately measuring your mattress avoids issues like gapping, slipping, and poor fitting you can get with an incorrectly sized protector.

Let's look at some examples of taking mattress measurements:

Example 1

  • Length: 76 inches
  • Width: 82 inches
  • Height: 12 inches without topper

This mattress would best fit a king size mattress protector. The 2 extra inches in width still allows a good fit. And the protector depth fits the 12 inch height.

Example 2

  • Length: 35 inches
  • Width: 75 inches
  • Height: 8 inches

These dimensions indicate a twin size mattress. The shorter length means a twin XL or larger protector would be too big.

Example 3

  • Length: 60 inches
  • Width: 70 inches
  • Height: 18 inches with 3 inch topper

This measures closest to a queen size mattress. The width is slightly shorter but a queen protector will still fit. And the total height of 18 inches needs a deep pocket protector.

Next, let's go over how to use your mattress dimensions to find just the right protector size.

Finding the Right Mattress Protector Size

Finding the Right Mattress Protector Size

With your precise mattress measurements in hand, use the following tips to determine the ideal mattress protector size:

  • Compare your mattress length, width, and height figures to standard sizes on a mattress chart. This gives a starting point.
  • Look for a protector that matches your mattress length and width as closely as possible. Being 1-2 inches under is okay.
  • For depth, find a protector designed for your mattress thickness or slightly larger. Protectors are elasticized and allow some leeway in depth.
  • Order the next size up if you are between standard mattress sizes. Oversized is better than undersized.
  • View mattress protector size charts from manufacturers to pick the recommended size for your bed.

The protector you choose should fit like a fitted sheet – nice and snug but not tight or baggy. With millions of combinations of mattress sizes and protector sizes, knowing your exact mattress dimensions takes the guesswork out.

At Mattress To Door, our mattress protector sizes range from twin to California king so you can always get an exact match. And we'll help determine sizing if you have any uncertainties.

Now let's overview the premium mattress protector options we offer designed to shield your investment.

Other Important Mattress Protector Considerations

Beyond getting the right size, there are a few other factors to weigh when picking out a mattress protector:

Materials – Most protectors feature polyester or cotton outer layers with waterproof vinyl backing. Newer materials like bamboo rayon add softness and moisture-wicking abilities. Always avoid 100% plastic protectors.

Features – Consider enhanced protectors with cooling gels for temperature regulation. Allergy blocking and antimicrobial options reduce dust mites, mold, and bacteria.

Mattress type – Make sure any protector matches the mattress construction (innerspring, latex foam, hybrid, etc). This ensures proper fitting and breathability.

Care – Check washing and drying recommendations from the manufacturer to maintain the protector properly.

Warranty – Look for at least a 10-year manufacturer warranty for durability and longevity.

At Mattress To Door, our friendly staff is happy to guide you through all these protector considerations specific to your mattress type and needs.

Mattress Protector FAQs

We get lots of common questions on mattress protector sizing and selection. Here are answers to some frequently asked questions:

What size protector should I get?

Use your precise mattress measurements to find the closest matching standard protector size. Size up if between mattress sizes.

How often do I need to replace my protector?

Most quality protectors will last 3-5 years with proper care. Replace sooner if the waterproof backing deteriorates.

Will a protector change mattress feel?

A good protector is thin and fits snugly to avoid altering mattress comfort. Avoid bulky, 100% plastic protectors.

How do I clean a mattress protector?

Check label instructions. Most protectors can be machine washed warm and tumble dried on low heat.

What is the best mattress protector material?

For softness and breathability, natural fibers like cotton and bamboo rayon are ideal. Make sure the underside is still waterproof vinyl.

Should I size up when ordering a protector?

Sizing up by one size is recommended if your mattress dimensions are in between standard sizes. An oversized protector will still fit better than one too small.
