Bed Size Calculator - Find the Perfect Mattress Size for Your Height

Choosing the right bed size is essential for quality sleep and comfort. Our bed size calculator helps you determine the ideal mattress length based on your height and region. By adding 20 cm (about 8 inches) to your height, you get enough space to stretch out comfortably. Whether you are shopping for a new bed in Europe or North America, this tool matches you with standard mattress sizes that fit your needs.

How to Calculate Bed Size

The general rule for finding a comfortable bed length is:

Minimum bed length: Equal to your height
Comfortable bed length: Your height + 20 cm (8 inches)

The extra 20 cm (8 inches) gives you enough room to stretch without your feet hanging off the edge. Bed width is more personal and depends on how much you move during sleep, your body size, and your bedroom space.

Tips for Choosing the Right Bed Size

Measure your bedroom: Make sure there is enough space to walk around the bed comfortably.
Consider your sleeping habits: If you move a lot during sleep, choose a wider bed.
Think about future needs: If you share your bed with a partner or pet, opt for a larger size.
Check door and stair dimensions: Make sure the bed frame can fit through hallways and doorways.
Account for bed frame thickness: The overall footprint may be larger than the mattress size.

Frequently Asked Questions

What bed size do I need if I am 6 feet tall?

If you are 6 feet tall (183 cm), a bed that is at least 190 cm (75 inches) long is the minimum, but 220 cm (86.5 inches) is ideal for maximum comfort. A Queen or King size bed in the US would work well. In Europe, look for a 200 cm or longer mattress.

What is the difference between King and Queen bed sizes?

The main difference is width. In the US, a King bed is 76 inches wide, while a Queen is 60 inches wide - a difference of 16 inches. In Europe, sizes vary by country and brand. Both are typically 80 inches (203 cm) long, though California King offers extra length at 84 inches.

How do I calculate the right bed size for my height?

Measure your height in centimeters or inches, then add 20 cm (8 inches) for comfort. Choose a standard mattress size that is at least this length. For example, if you are 180 cm tall, look for a mattress that is at least 200 cm long.

What bed size is 60 x 80 inches?

A 60 by 80 inch bed is a Queen size mattress. This is one of the most popular bed sizes in North America, offering a good balance of space for couples while fitting in most bedrooms.

Should I buy a larger bed than I need?

It is generally recommended to buy the largest bed that fits your space and budget. Extra space improves sleep quality, reduces disturbance from a partner, and allows for comfortable movement. Just ensure you have at least 60-70 cm of walking space around the bed.
