Factors like room size, how active a sleeper you are, and whether or not you share a bed influence which sizes the best suit your needs. Understanding the dimension and names will help you narrow down the options to help you find the right bed size to suit your specific needs.
Remember that height/thickness varies depending on the manufacturer and model, so there is no universal thickness for each mattress size.

How to Measure your Mattress

What’s the perfect Mattress Size? Start with measuring to define your preferred Mattress. The main reason is that choosing the right mattress size is mainly a choice based on personal preferences. Take the measurements of your room also into account when choosing your Mattress Size.

Time needed: 3 minutes.

Measure your mattress size in 6 simple steps, with extra steps to be sure you have chosen the perfect bed for your sleep

  1. Make sure your mattress is free of blankets, sheets, and pillows

    It is best to measure the correct size of your mattress when there is absolutely nothing on it. If there is a comfort layer on your mattress, feel free to leave it.

  2. Measure the width of your mattress from left to right.

    Mattresses can bend towards the ends, so be sure to measure from the ends of each side of the mattress.
    Use a flexible ruler or tape measure when measuring. Write the measurements on a piece of paper so you don’t forget them.

  3. Measure the length of your mattress from the foot end to the head end.

    When your mattress deflects at the head and foot end, be sure to measure the furthest point from each side.

  4. Measure the height from the bottom to the top of the mattress

    When you have a comfort layer on your mattress, feel free to leave it in your measurement. If not, only measure the height of the mattress.

  5. Apply these measurements in the size tables below of this article

    These measurements will help you choose the standard size of the mattress of your choice. The standard Mattress sizes are Twin, Twin XL, Full, Queen, King and California King

  6. Extra: Measure the doorways and hallways in your home before purchasing a new mattress

    This is a very important dimension because you have to be absolutely sure that the mattress of your dreams. Choose the width of your mattress so that it can pass through the lowest doorway in your house where you have to carry it
    Pay attention to the width and height of stairs that you have to pass with the mattress

  7. Extra: Measure the bed frame before you buy the mattress.

    This sounds logical, but it is recommended that you also measure your bed frame. Or when you buy a separate bed frame, it is best to check the dimensions, as these can vary from different manufacturers.

  8. Extra: Measure your room

    Make sure there is enough space around the bed or mattress you plan to buy. This space is preferably provided along 3 sides of the mattress so that you can walk smoothly past your bed. We have written a separate article about this topic.

Remember that height/thickness varies depending on the model/brand of the mattress, so there is no universal thickness for each mattress size.

Mattress type: spring mattress, foam, hybrid, foam or latex

The most popular mattresses continue to be the traditional spring mattresses. They feature a steel coil core and a foam comfort layer. Their advantages are strong edge support and excellent bounce, but they are prone to sagging, producing the classic squeaky bed sound, and they don’t adapt well to the body.

Some spring mattresses feature individually wrapped pocket springs. This construction helps to minimize motion transfer. Think of the old advertisements where a bowling ball falls on a mattress. If you are sharing a bed with a partner, you might want to consider individually wrapped coils to make sure they don’t wake you up when they move through the night.

They are made up of several layers of foam that adapt to your body. Although they last longer than spring mattresses, they tend to trap heat.

Hybrid mattresses combine internal springs and memory foam. They have many layers of foam on a core of pocket springs. This combats the heat trapping problem commonly encountered with memory foam when contouring the body. However, hybrid mattresses tend to cost more than memory foam and springs.

Two other less common and more expensive options are latex mattresses and air mattresses. Latex provides rounded body support and bounce, but it emits a long-lasting outgassing odor. Air mattresses combine layers of foam comfort with inner tube support. An air pump lets you adjust your firmness, and air mattresses are surprisingly durable.
