Chloé Simo
The size of your mattress directly influences the quality of your sleep.
Yet, many people simply choose the same mattress as their previous one. Did you know that, on average, a mattress is used for 10 to 15 years? In a decade, your lifestyle, your sleeping preferences, and even the size of your bedroom can change.
To avoid the discomfort of an ill-suited mattress, discover in this guide all the available sizes, their advantages and our practical advice to make the perfect choice according to your needs.
The importance of choosing the right mattress size
Choosing the right mattress size shouldn't be taken lightly, as it directly impacts the quality of your sleep. An incorrectly sized mattress can lead to restless nights, discomfort, and even long-term posture problems.
Here are the key elements to consider when choosing the size of your mattress:
1. Your body type
The ideal mattress size depends on your personal height and body shape. As a general rule, it's recommended to add 10 to 20 centimeters to your height to achieve the optimal mattress length. A mattress that's too short can cause discomfort during the night.
2. Your situation
Your personal circumstances also play a crucial role in choosing the right mattress size. Here are some common scenarios:
- If you sleep alone, a single mattress size, such as 90x190 cm or 90x200 cm, may be sufficient. However, if you tend to move around a lot at night or prefer more space, consider a larger mattress size, such as 140x190 cm or 140x200 cm.
- If you share your bed with a partner, it's essential to consider their size when choosing a mattress. A mattress that's too narrow can create a lack of space and disrupt your sleep. Standard mattress sizes for couples include 140x190 cm, 140x200 cm, 160x200 cm, and 180x200 cm.
- If you have children or pets who share your bed from time to time, consider a larger mattress size to comfortably accommodate everyone.
3. The size of your room
Finally, the size of your bedroom is an important factor when choosing a mattress size. Make sure to leave at least 60 centimeters of space around the bed so you can move around the room easily. If your bedroom is small, opt for a mattress size that fits well without overwhelming the space.

To delve deeper, we answer the most frequently asked questions:
1. What mattress length should I choose?
Generally, it is recommended to choose a mattress 10 to 20 centimeters longer than your height for optimal comfort. Therefore, if you are 1.80 meters tall, a mattress 190 cm or 200 cm long would be suitable.
2. What size mattress and bed base should I choose?
A mattress should always be the same size as the bed base to avoid any fitting problems. For example, for a 90x200 cm bed, you should therefore choose a 90x200 cm mattress as well.
3. Is it possible to use two 90x200 cm mattresses with a King Size bed base?
Yes, it's perfectly possible. Two 90x200 cm mattresses placed side by side are equivalent to a king-size mattress measuring 180x200 cm. This option is commonly chosen by couples with different sleeping preferences. It's also a good option for those who want to use an adjustable bed base. By choosing two 90x190 cm mattresses on a king-size bed base, you can use a 180x200 cm base or two 90x200 cm beds.
How do I determine the size of my mattress?
To measure the size of your mattress, use the external dimensions of the bed as a reference point. The mattress should be slightly smaller than the bed, generally 2 centimeters less in length and width, to avoid any bulkiness.
Conclusion
Choosing the right mattress size is essential for peaceful and comfortable nights of sleep. There are many mattress size options available, but the ideal size depends on your body type, personal circumstances, bedroom size, and preferences. Take the time to measure, consider your needs, and choose the size that best suits you to enjoy restful sleep night after night. It's a wise investment in your long-term health and well-being.
