Choosing the right mattress is a big decision, and it all starts with knowing the correct size. If you’re wondering what are the measurements of a double size mattress, you’re in the right place. A double mattress, also commonly called a full-size mattress, is a popular choice for single sleepers who want more space or for cozy couples rooms.
Getting the measurements right is crucial for buying sheets, a bed frame, or planning your bedroom layout. This guide will give you all the details you need about double mattress dimensions, plus tips for choosing the best one for your needs.
What Are The Measurements Of A Double Size Mattress
In the United States and Canada, a standard double size mattress measures 54 inches wide by 75 inches long. When converted to feet, that’s 4 feet 6 inches wide by 6 feet 3 inches long. In metric measurements, this is approximately 137 cm wide by 191 cm long.
It’s important to remember that these are the standard dimensions for the mattress itself. The overall footprint of your bed will be larger once you add the bed frame or headboard. Always allow for a few extra inches on each side when planning your room layout.
Comparing Double to Other Mattress Sizes
To truly understand the size of a double, it’s helpful to compare it to other common mattress sizes.
* Twin (Single): 38″ x 75″. A double is 16 inches wider than a twin, offering significantly more sleeping width for a single adult.
* Twin XL: 38″ x 80″. Same width as a twin but 5 inches longer. A double is wider but shorter than a Twin XL.
* Queen: 60″ x 80″. This is 6 inches wider and 5 inches longer than a double. The queen is now the most popular size for couples.
* King: 76″ x 80″. A full 22 inches wider than a double, offering ample space for two people and maybe even pets.
* California King: 72″ x 84″. Narrower but longer than a standard king.
The double sits in the middle, offering a upgrade from a twin without committing to the larger footprint of a queen.
Who is a Double Size Mattress Best For?
A double mattress is a versatile choice for several types of sleepers and situations.
* Single Adults: It’s an excellent upgrade from a twin for a single adult who enjoys having extra room to spread out.
* Teenagers: The extra width compared to a twin is perfect for growing teens, and it can last them through college or into their first apartment.
* Guest Rooms: It’s a space-conscious yet comfortable option for a guest bedroom, accommodating single guests or couples in a pinch.
* Smaller Primary Bedrooms: For older homes or apartments with smaller rooms, a double can fit better than a queen while still providing good comfort.
* The Budget-Conscious: Double mattresses, frames, and bedding are often less expensive than queen or king sizes.
However, for two adults who sleep together regularly, a double can feel quite cramped. Each person gets only 27 inches of width, which is less than a crib mattress. For couples, a queen is generally the recommended starting point.
Important Considerations for Couples
If you are a couple considering a double bed, think about your sleep habits. Do you or your partner tend to move around alot during the night? Do you both like to sprawl out? If the answer is yes, the 54-inch width might lead to disrupted sleep. It can work for couples who sleep very close together or in smaller spaces, but be aware of the limitations.
Bedding and Accessories for a Double Mattress
Once you have your mattress, you’ll need the correctly sized bedding. Using the wrong size sheets can be uncomfortable and may even damage your mattress.
* Fitted Sheet: Look for a “Full” or “Double” size fitted sheet, which should be labeled for a 54″ x 75″ mattress. Always check the depth (like “pocket depth”) to ensure it fits your mattress’s thickness.
* Flat Sheet: A standard double/flat sheet is usually around 81″ x 96″.
* Comforter/Duvet: Double size comforters are typically designed to drape over the sides. Common dimensions are 80″ x 90″ or 86″ x 86″.
* Mattress Protector: This is essential for keeping your investment clean. Buy one specifically labeled for a full/double bed.
* Bed Frame/Base: Ensure your bed frame or foundation is designed for a double mattress. Common frame sizes will list “Full/Double” in the description.
Always double-check the product specifications before you buy, as sizing can vary slightly between brands, especially with sheets.
How to Measure Your Space for a Double Bed
Before you buy, it’s crucial to measure your bedroom. Here’s a simple step-by-step guide:
1. Measure Your Room: Use a tape measure to find the length and width of your bedroom. Write these numbers down.
2. Plan the Layout: Decide where the bed will go. Remember to account for doors, windows, and closets that need to open fully.
3. Add to the Mattress Size: Add at least 2-3 feet to both the width and length of the mattress for the frame. For example, a double bed’s total footprint might be around 58″ x 80″.
4. Check Walkways: Ensure there is at least 24 inches of walking space on at least one side of the bed and at the foot. More space (30-36 inches) is better for easy movement and cleaning.
5. Consider Other Furniture: Don’t forget to leave space for nightstands, a dresser, or a chair. Sketching a quick floor plan can be very helpful.
A double bed is often a great choice for rooms that are at least 10 feet by 10 feet, but careful planning can make it work in slightly smaller spaces too.
Special Mattress Types and Their Dimensions
The standard 54″ x 75″ measurement applies to most innerspring, memory foam, latex, and hybrid mattresses. However, there are a few exceptions to be aware of.
* Adjustable Beds: Double size adjustable bases are made to the standard 54″ x 75″ dimension. Ensure your mattress is compatible with bending (most memory foam and latex are).
* Antique or Vintage Beds: Older double beds, sometimes called “full” beds, might have slightly different dimensions. If you have an antique frame, measure the interior space carefully before buying a new mattress.
* European Sizes: In the UK and Europe, sizing is different. A UK “double” is typically 135cm x 190cm (approx. 53″ x 75″), which is very close but not identical. Always verify if buying internationally.
* RVs and Campers: Mattresses in recreational vehicles often use unique sizes. While some may use a standard double, many are custom. Measure your RV bed space precisely.
Dealing with a Non-Standard Frame
If your existing bed frame is an odd size, you have a couple options. You can order a custom-made mattress to fit, which is more expensive. Alternatively, you can use a size-close mattress and fill small gaps with foam wedges, but this isn’t ideal for support.
Tips for Buying a Double Mattress
Shopping for any mattress can be overwelming. Here are key points to focus on when looking for a double.
* Set a Budget: Mattress prices vary wildly. Determine what you can spend before you start looking.
* Test for Comfort: If shopping in-store, lie down on the mattress in your typical sleep position for at least 10-15 minutes. Don’t feel rushed.
* Consider Sleep Position: Side sleepers often need a softer mattress to cushion hips and shoulders. Stomach and back sleepers usually need firmer support.
* Check the Return Policy: Many online brands offer long sleep trials (100 nights or more). Understand the return process and any associated fees.
* Look at Warranty: A good mattress should come with a warranty of at least 10 years. Read the fine print about what is covered.
Remember, the best mattress for you is the one that feels comfortable and supports your spine properly. Don’t just buy based on a brand name or price alone.
Caring for Your Double Mattress
Proper care will extend the life of your mattress significantly. Follow these simple steps:
* Use a Protector: A waterproof, breathable mattress protector is your first line of defense against spills, stains, and dust mites.
* Rotate Regularly: For the first year, rotate your mattress head-to-foot every 3 months. After that, every 6 months is fine. This prevents uneven wear. (Flip it too if it’s double-sided).
* Clean Spills Immediately: Blot any liquid spills with a clean cloth. Use a mild soap with water for cleaning, and let the area dry completely before putting sheets back on.
* Vacuum Occasionally: Use your vacuum’s upholstery attachment to remove dust and allergens from the surface.
* Support it Right: Make sure your mattress is on a proper, supportive foundation. A saggy box spring or slats that are too far apart can void your warranty and ruin the mattress.
Taking these steps can help your mattress stay comfortable and supportive for many years.
Common Mistakes to Avoid
When dealing with mattress sizes, a few common errors can cause headaches.
* Assuming “Full” and “Double” are Different: In North America, they are the same thing. Don’t pay more for one term over the other.
* Guessing Sheet Size: Trying to use queen sheets on a double bed will lead to a loose, messy fit. Always buy the correct size.
* Not Measuring the Room: The worst feeling is getting a new bed delivered only to find it blocks a door or leaves no room for a nightstand.
* Forgetting About Height: Modern mattresses, especially pillow-tops or all-foam models, can be very tall. Make sure your sheets are deep enough and that the height looks proportional in your room.
* Ignoring Delivery Access: Measure your hallways, staircases, and doorways to ensure the mattress can actually get to your bedroom. Double mattresses are much easier to maneuver than kings, but it’s still a good check.
Avoiding these pitfalls will make your entire experience much smoother.
