About This Calculator
Choosing the right bed size is essential for comfortable sleep and overall health. Our bed size calculator helps you find the ideal mattress dimensions based on your height and region. Whether you are shopping for a new bed, moving into a new home, or simply checking if your current bed is the right fit, this tool provides personalized recommendations instantly.
The calculator uses the standard ergonomic guideline that a bed should be at least 10-20 cm (4-8 inches) longer than your height. This ensures you have enough room to stretch and move during sleep without your feet hanging off the edge. The ideal bed length is calculated as your height plus 20 cm, while the minimum comfortable length is your height plus 10 cm.
Standard Bed Sizes by Region
North America (US/Canada): Twin (97x190 cm), Twin XL (97x203 cm), Full (135x190 cm), Queen (152x203 cm), King (193x203 cm), California King (183x213 cm). Queen is the most popular choice for couples.
Europe: Single (90x190/200 cm), Small Double (120x190 cm), Double (140x190/200 cm), Queen (160x200 cm), King (180x200 cm), Super King (200x200 cm). European beds are typically longer than North American standard sizes.
India: Follows European standard sizes. Common options include Single (90x190 cm), Double (140x190 cm), Queen (150x200 to 160x200 cm), and King (180x200 cm). Most Indian manufacturers offer custom sizes as well.
UK: Small Single (76x190 cm), Single (91x190 cm), Small Double (122x190 cm), Double (137x190 cm), King (152x200 cm), Super King (183x200 cm). UK sizes are slightly different from European and North American dimensions.
How to Choose the Right Bed Width
While this calculator focuses on bed length based on your height, width is equally important. For single sleepers, a Twin/Single (90-97 cm wide) provides sufficient space. Couples should consider a Queen (152-160 cm) or King (180-193 cm). If you move a lot during sleep or share the bed with pets or children, opt for a wider size than the minimum recommendation.
Room Size Considerations
Before purchasing a bed, measure your bedroom to ensure the new mattress fits comfortably. Allow at least 60-90 cm (24-36 inches) of walking space on each side and 90 cm (36 inches) at the foot. A good rule of thumb is that the bed should not take up more than 50-60% of the total floor area for a balanced room layout.
Frequently Asked Questions
What bed size do I need for my height?
For comfortable sleep, your bed should be at least 10-20 cm (4-8 inches) longer than your height. For example, if you are 170 cm tall, look for a bed that is at least 180 cm long, ideally 190 cm. This allows enough room to stretch without your feet hanging off the edge.
How do I calculate the right bed size?
Measure your height and add 20 cm (8 inches) for optimal comfort. Then check standard mattress sizes in your region. If you are 175 cm tall, a 195 cm long bed is ideal. In North America, a Twin (190 cm) works as minimum or Twin XL (203 cm) for comfort. In Europe/India, a 90x200 or 140x200 cm mattress provides ample length.
What is the difference between King and Queen bed sizes?
In North America, a Queen is 152x203 cm (60x80 inches), while a King is 193x203 cm (76x80 inches) — 41 cm wider. In Europe, a Queen (160x200 cm) and King (180x200 cm) differ by 20 cm in width. Both are 200 cm long. Choose based on your room size and whether you sleep alone or with a partner.
