Mattress Size Guide

 Twin Mattress Size – 39″ x 75″

A Twin mattress is commonly found in children’s rooms, guest bedrooms, and some college dorm rooms. The twin size mattress dimensions are 39 inches wide by 75 inches long. It’s a great option for overnight guests and fits well in small spaces in general.


Twin XL Mattress Size – 39″ x 80″

The Twin XL mattress is the most common bed size in traditional college dorms. It’s called the “Twin XL” because it’s 5 inches longer than standard Twin mattresses. It’s 39 inches wide by 80 inches long. This size is perfect for taller adults with a small bedroom.


Full Mattress Size – 54″ x 75″

A Full mattress is an ideal option for a guest room or a teenager who has outgrown their kid bed. It’s 54 inches wide and 75 inches long, which is 15 inches wider than a Twin and 5 inches shorter than a Queen. This size is fit for someone who loves a balance of living space and sleeping space.


Queen Mattress Size – 60″ x 80″ 

The Queen mattress is the most popular size mattress. It’s 60 inches wide and 80 inches long, making it 6 inches wider and 5 inches longer than a Full-size bed. This is a great bed for two adults to sleep in a small Master Bedroom (at least 10 feet wide by 10 feet long) comfortably.


King Mattress Size – 76″ x 80″

The King mattress is the best option if you want a lot of sleeping space. It’s 76 inches wide by 80 inches long. It’s 16 inches wider than a queen, which is best for two people or one person with a dog. That’s over a foot wider! If you have a big master bedroom or a master suite, consider the King for a luxurious choice.


Do Your Sheets Fit Your Mattress?

Mattresses come in pretty standard length and width measurements, but they can vary greatly in depth. Most mattresses are between 8 and 14 inches thick. However, just a few inches can make a huge difference in how your sheets fit.

Avoid ripping your sheets from a super tight fit or sleeping on a wrinkly fitted sheet. Your fitted sheet should be snug but not too taut. Follow these steps to get the appropriate sheets for your mattress:

Step 1: Measure the thickness of your mattress setup. Make sure you measure after the mattress protector and mattress topper are set up on top to get the most accurate depth. You’ll need this number in inches for shopping for sheets and other bedding.

Step 2: Look for sheets in the appropriate thickness. If you have a 12-inch mattress and a 2-inch mattress topper, you probably want to shop for deep pocket fitted sheets. If you have a traditional 10-inch mattress and no mattress topper, standard sheet sizes should fit your mattress perfectly. Read the sheet packaging closely or read online reviews about the sheets to learn more about the fit.

Step 3: Make your bed with the brand new sheets to make sure they fit nicely. If they do, strip your bed and toss them in the washer and dryer. As tempting as it is to use soft new sheets straight out of the package, wash them first! New sheets are covered in fibers and chemicals that could be irritating to your skin. Follow the instructions on the tag and wash them alone to avoid dyeing any other linens or clothes.

If you like the oversized fit of duvet covers and comforters, it’s important to pay attention to the thickness of your mattress and box spring so your bedding hangs as low as you’d like it to.
