Determine Your Mattress Size

The first step to buying a replacement mattress is to figure out what size you need to order.

 

Standard Home Sizes

  1. Twin            39×75
  2. Twin XL      39×80
  3. Full /Double 54×75
  4. Full/Dbl XL  54×80
  5. Queen         60×80
  6. King        76×80
  7. Cal King       72×84

 

For RV (SUV, Van, Truck)

Though most people measure the mattress, the most accurate way to do it is to measure the dimensions of the surface the mattress rests on, plywood or some similar surface.

There are several reasons why:

  1. The mattress may have been replaced and not be the same size as it was when the RV was built
  2. The mattress is missing, or it is for a custom build-out
  3. Natural variance in production size
  4. Fluctuations in temperature during off-season storage or from exposure to UV light

 

 If you measure the RV mattress instead of the surface it lies on, it may lead you to believe that you need a custom mattress size.

 Don’t worry, measuring is easy!

 

Here are the most common RV sizes:

  1. Three Quarter Size : 48″ x 75″
  2. RV Full: 53″ x 75″
  3. Short Queen : 60″ x 75″ (most common short queen size)
  4. Short Queen: 60″ x 74″
  5. RV Queen : 60″ x 80″
  6. Olympic Queen : 66″ x 80″
  7. RV King: 72″ x 75″
  8. RV King: 72″ x 80″
  9. Cal King: 72″ x 84″
  10. Eastern King: 76″ x 80
  11. RV Bunk: 28″ x 75″
  12. RV Bunk: 30″ x 75″
  13. RV Bunk: 30″ x 80″
  14. RV Bunk: 34″ x 75″
  15. RV Bunk: 35″ x 79″
  16. RV Twin : 38″ x 75″
  17. RV Twin : 38″ x 80
  18. RV Bunk: 42″ x 80″

It’s also possible that you might need one of the common “truck mattress” sizes if you're replacing a mattress for a bunk in your RV.

The common truck mattress sizes are:

  1. 42″x80″
  2. 38″x80″
  3. 32″x79″
  4. 36″x76″
  5. 35″x79″

There are many other sizes available, but these are the most popular.

The most common RV mattresses are in the shape of a rectangle.

*Custom sizes include anything from odd rectangle sizes, to mattresses with cut or rounded corners (some airstream RVs for example or van mattress beds).
