Understanding Bed Dimensions
The "calculator" on this page is a reference tool. By selecting a standard bed size, you can instantly see its dimensions in both inches and centimeters. This helps in planning your bedroom layout and ensuring a new bed will fit comfortably.
Standard US Bed Sizes:
- Crib: 28" × 52" (71cm × 132cm) - Designed for infants and toddlers.
- Twin: 38" × 75" (97cm × 191cm) - Ideal for kids, bunk beds, and single adults in small spaces.
- Twin XL: 38" × 80" (97cm × 203cm) - Common in college dorms, offering extra length for taller individuals.
- Full (Double): 54" × 75" (137cm × 191cm) - A good option for single sleepers who want more room to spread out. It can accommodate a couple, but may be tight.
- Queen: 60" × 80" (152cm × 203cm) - The most popular mattress size, offering a comfortable space for couples or a luxurious amount of room for a single sleeper.
- King: 76" × 80" (193cm × 203cm) - Provides a great deal of personal space for couples. It's the same length as a Queen but significantly wider.
- California King: 72" × 84" (183cm × 213cm) - Narrower but longer than a standard King, making it a better choice for taller individuals who need extra legroom.
How to Choose the Right Bed Size
Consider these factors when making your decision:
- Room Size: A general rule of thumb is to have at least 24-30 inches of walking space around the sides of your bed. Measure your room and account for other furniture like dressers and nightstands.
- Your Height and Sleep Style: If you are over 6 feet tall, a Twin or Full mattress (75 inches long) may feel short. A Twin XL, Queen, or King (80 inches) or a California King (84 inches) would be a better fit. If you toss and turn, a wider bed like a Queen or King will provide more comfort.
- Who Will Be Sleeping in the Bed: A single person can be comfortable on anything from a Twin to a King. For couples, a Queen is usually the minimum recommended size for comfortable sleeping, with a King providing a more luxurious, spacious feel.
- Budget: Larger mattresses are more expensive, and the cost of bedding (sheets, comforters, etc.) also increases with size. Factor these into your overall budget.
