A chart for bed sizes is an essential tool when you’re shopping for a new mattress. It provides the standard dimensions—width and length—for each common mattress size. Knowing these measurements helps you visualise how a bed will fit in your room and whether it meets your personal space requirements. Let’s break down the most common options.
Crib Bed Size
Dimensions: 28 inches x 52 inches
A Crib mattress is designed specifically for infants and toddlers. These dimensions are standardised in the United States for safety reasons, ensuring a snug fit within a standard crib frame to prevent any gaps.
Twin Bed Size
Dimensions: 38 inches x 75 inches
The Twin is the smallest of the standard adult beds. It’s a great choice for children’s rooms, bunk beds, daybeds, and small guest rooms. Its compact size makes it ideal for single sleepers and maximising floor space in smaller areas.
Twin XL Bed Size
Dimensions: 38 inches x 80 inches (96.5 × 203.5 CM)
The Twin XL has the same width as a standard Twin but offers an extra 5 inches in length. This makes it a popular choice for college dorm rooms and for taller teenagers or single adults who need more legroom. Two Twin XL beds can also be pushed together to form a Split King, offering customised comfort for couples.
Bed size full dimensions
Dimensions: 54 inches x 75 inches (137 × 190.5 CM)
Often referred to as a double bed size, the Full mattress is a significant step up in width from a Twin. It was the standard for couples for many years before the Queen-size became more popular. Today, it’s an excellent option for single adults who want more room to spread out than a Twin offers.
Queen size bed dimensions
Dimensions: 60 inches x 80 inches (152 × 203.5 CM)
The Queen is currently the most popular mattress size in the United States, and for good reason. It offers ample space for single sleepers and is a comfortable option for most couples. Its dimensions provide a good balance between personal space and fitting comfortably into most primary bedrooms.
King size bed dimensions
Dimensions: 76 inches x 80 inches (193 × 203.5 CM)
Also known as the Standard or Eastern King, this mattress offers a luxurious amount of space. It’s the widest of the standard sizes, providing each sleeper with the equivalent of their own Twin XL bed. A King bed is perfect for couples who want maximum personal space or for families who enjoy a weekend cuddle with the kids.
California King Bed Size
Dimensions: 72 inches x 84 inches (183 × 213.5 CM)
The California King Size Bed (or Cal King) trades some width for extra length compared to the standard King. While it’s 4 inches narrower, it’s also 4 inches longer. This makes it the ideal choice for very tall individuals or for narrower primary bedrooms where the extra length is more valuable than the width.

A Deeper Dive: The Full-Size Bed
The Full bed holds a unique place in the mattress world. It’s a versatile option that bridges the gap between smaller Twin sizes and larger Queen and King sizes. Let’s take a closer look at the specifics of this popular choice.
What are the Full Size Bed Dimensions?
The standard Full size bed dimensions are 54 inches wide by 75 inches long. To put that in perspective, this is 16 inches wider than a Twin bed but has the same length. It’s a common misconception that a Full bed is twice the width of a Twin, but that is not the case.
When you see the term full bed measurements, this is what it refers to. The total surface area is 4,050 square inches, providing a good amount of space for a single person to sleep comfortably without feeling cramped.
Full Size Bed Dimensions in Feet
Sometimes it’s easier to visualise a bed’s size in feet. The full-size bed dimensions in feet are 4.5 feet wide by 6.25 feet long. Seeing the measurements this way can help you plan your room layout more effectively. If you’re using a tape measure to mark out the space, thinking in feet can provide a better sense of scale.
Is a Full Bed Right for You?
The Full bed, or double bed size, is an excellent choice for several situations:
- Single Sleepers: It’s perfect for single adults who find a Twin too narrow. The extra width allows for more room to turn over and spread out.
- Growing Teenagers: A Full bed is a great upgrade for a teenager who has outgrown their childhood Twin bed.
- Guest Rooms: It’s a comfortable and space-efficient choice for a guest room, offering more comfort for visitors than a Twin.
- Couples (with a catch): While couples can share a Full bed, it can be a tight squeeze. Each person would only have 27 inches of personal width, which is the same width as a crib mattress. It can work for smaller adults or for occasional use, but most couples prefer the extra space of a Queen.
The full bed length is 75 inches (6 feet 3 inches), which is sufficient for most people. However, individuals taller than 6 feet might find their feet dangling off the end and may be more comfortable with a Queen or Twin XL, both of which are 80 inches long.
Visualising Bed Sizes in Inches
Thinking about bed size by inches is the most precise way to plan your bedroom. Here’s a quick reference table to help you compare the different options directly.
| Bed Size | Dimensions (Width x Length) |
| Crib | 28″ x 52″ |
| Twin | 38″ x 75″ |
| Twin XL | 38″ x 80″ |
| Full / Double | 54″ x 75″ |
| Queen | 60″ x 80″ |
| King | 76″ x 80″ |
| California King | 72″ x 84″ |
This chart makes it easy to see how each bed size compares to the next. For instance, you can quickly see that a Queen bed gives you 6 more inches of width and 5 more inches of length compared to a Full bed. A King bed provides a massive 16 inches of additional width compared to a Queen-size bed, making it a truly luxurious option.
Factors to Consider When Choosing a Bed Size
Beyond the raw dimensions, several other factors should influence your decision
Room Size
This is the most critical factor. You need to ensure your chosen bed doesn’t overwhelm the room. A good rule of thumb is to leave at least 2 to 3 feet of walking space around the sides and foot of the bed. This ensures you can move around comfortably, open dresser drawers, and access closets without feeling cramped.
Before you buy, use a tape measure and masking tape to mark the bed’s dimensions on the floor. This will give you a real-world visual of how much space it will occupy.
Who Will Be Sleeping in the Bed?
- Single Sleepers: A Twin, Twin XL, or Full can work well. The choice often comes down to personal preference for space and the sleeper’s height.
- Couples: Most couples will find a Queen or King to be the most comfortable. A Full bed is often too narrow for two adults to sleep comfortably every night.
- Families: If you have children or pets who like to pile into bed with you, a King or California King is your best bet. The extra space is invaluable for keeping everyone comfortable.
Your Height and Sleep Style
Your physical height is a key consideration. If you are over 6 feet tall, you should look for a bed that is at least 80 inches long. This means a Twin XL, Queen, King, or California King. The 75-inch length of a Twin or Full might leave you feeling cramped.
Also, consider your sleeping style. Do you curl up in a ball, or do you spread out like a starfish? If you’re an active sleeper who moves around a lot, you’ll appreciate the extra width of a Queen or King, even if you sleep alone.
Don’t Forget the Bedding Size Chart
Once you’ve chosen your mattress, you need to buy the right bedding. While it might seem straightforward, a bedding size chart can be very helpful, especially with variations in mattress depth.
Modern mattresses, especially pillow-top and hybrid models, can be significantly thicker than older models. A standard fitted sheet might not fit a mattress that is 14 or 15 inches deep. When shopping for sheets, look for “deep pocket” options if you have a thicker mattress.
Here’s a general guide for flat sheets and comforters, which should be larger than the mattress to allow for drape over the sides:
- Twin: Flat sheet (approx. 66″ x 96″), Comforter (approx. 68″ x 88″)
- Full: Flat sheet (approx. 81″ x 96″), Comforter (approx. 84″ x 88″)
- Queen: Flat sheet (approx. 90″ x 102″), Comforter (approx. 90″ x 94″)
- King: Flat sheet (approx. 108″ x 102″), Comforter (approx. 106″ x 94″)
Always check the packaging for specific dimensions to ensure a proper fit for your new bed.
