Choosing the right bed is not just a matter of aesthetics – it’s essential for healthy, comfortable sleep. A bed that is too short can leave you cramped, while one that is too narrow may restrict your movement during the night.
Our Bed Size Calculator helps you instantly find the minimum and recommended bed length based on the height of one or two people. This way, you can quickly determine which dimensions are best for you – whether you sleep alone or share a bed with a partner.
How does the Bed Size Calculator work?
The bed size calculator is a practical tool that instantly shows you which bed dimensions will ensure maximum comfort. It takes into account the height of one or two people, as well as standard measurements used in different regions of the world – Europe, North America, and Australia.
The calculator doesn’t just calculate the minimum length required for comfortable sleep – it also suggests standard bed sizes available in stores. This means you don’t have to guess or risk buying a bed that’s too short or too narrow – the results are presented clearly and precisely.
How to use the Bed Size Calculator step by step?
The calculator is designed to be simple and intuitive. Even if you’re not familiar with bed size standards, you can easily find the right option:
- Choose your region: Europe, North America, or Australia.
- Enter your height (for one person) or the height of both people (for couples).
- Select your unit: inches or centimeters.
- The calculator will compute the minimum and comfortable bed length.
- You’ll also see a list of recommended bed sizes available in your region.
In just a few seconds, you’ll get a clear answer about which bed size will help you sleep comfortably.
Choosing the right bed size for one person
Selecting the correct bed size for a single sleeper is crucial for good rest. A bed that is too short won’t let you stretch out, while a narrow one may limit your comfort. The calculator uses your height to determine the minimum and comfortable length, and it also suggests standard widths so you can pick the best option.
This helps you decide whether a narrow twin bed is enough, or if you’d prefer something wider for extra space at night.
Minimum and comfortable bed length
- Minimum length – your height plus a few extra inches, just enough to stretch your legs.
- Comfortable length – your height plus additional allowance, ensuring you sleep not only without restrictions but also in complete comfort.
Standard bed sizes for one person
In North America, common single bed sizes include:
- Twin: 38 × 75 in (97 × 191 cm)
- Twin XL: 38 × 80 in (97 × 203 cm)
- Full: 54 × 75 in (137 × 191 cm)
In Europe, typical equivalents are 80 × 200 cm, 90 × 200 cm, or 100 × 200 cm.
How to choose a bed size for two people?
Sharing a bed requires more space and comfort. For couples, both length and width are important, so each person can sleep without feeling restricted. The calculator automatically bases the minimum length on the taller person, then recommends standard widths for two sleepers – from more compact options to luxurious king-sized beds.
This ensures that both partners have enough room to sleep peacefully, even if one tends to move around during the night.
Popular widths include 54 in (Full), 60 in (Queen), 76 in (King), and 80 in (California King). The wider the bed, the more personal space each partner enjoys.
Regional differences in bed sizes
Bed sizes vary by region, which is important when shopping internationally.
- In Europe, the most common bed length is 200 cm (79 in).
- In North America and Australia, typical lengths are 75 in (190 cm) or 80 in (203 cm).
Widths also differ:
- In the US, standard terms include Queen (60 in / 152 cm wide) and King (76 in / 193 cm wide).
- In Europe, people often refer to double, matrimonial, or king-size beds.
The calculator makes this easy by automatically converting and suggesting the right size based on your input.

Bed Size Calculator - FAQ
