What Are the Dimensions of a Full-Size Bed Frame?

When it comes to bed sizes, full-size (also called a “double bed”) is a classic choice. Excellent for a variety of bedrooms and sleepers, full-size beds can comfortably fit one adult, are perfect for growing kids, and can even work for couples in cozy bedrooms. Data shows that about 15% of beds purchased are full-size.1

Before you buy a beautiful new full-size bed for your space, you’ll need to dot your i’s and cross your t’s when it comes to dimensions, so you can ensure your new bed will fit comfortably in your existing space.

So, what are the dimensions of a full-size bed frame? Usually, they measure somewhere between 56 and 59” wide, and 77 and 80” long. We’ll be breaking down all of the different types of full-size beds you’ll find in stores today.

Full Mattress and Bed Frame Dimensions

A standard full-size mattress is typically 54” wide by 75” long. All bed frames will be slightly larger than the mattress alone to ensure stability and sometimes include add-on features. That’s why most full bed frames are 56” by 77.” However, bed frames with drawers, posts, or additional adornments often measure even larger.

Full vs. Full XL Bed Frame

As you’re researching full size bed frames, you’ll likely come across full XL bed frames, too. What’s the difference between the two mattress sizes? A full XL is an extra-long version of its standard counterpart. While the width is the same (54”), the length of the full XL is typically 80”, which gives you five extra inches to stretch all the way out.

Full XL beds are perfect for taller individuals who find a standard full bed too short. They’re also an excellent choice for those who want more legroom, who sleep with pets at the foot of their bed, or who want to comfortably accommodate taller visitors in their guest room.

Who is a Full-Size Bed Good For?

A full bed size offers the perfect sweet spot between an ultra-cozy twin bed and a spacious queen bed. But how can you know if a full-size bed is the right choice?

If you find yourself on this list, a full bed might just be perfect for you:

  • Solo sleepers (who prioritize comfort) – Full-size beds give you ample space to spread out comfortably, without taking up too much space in a smaller bedroom.
  • Growing youngsters – Investing in a full bed size makes sense for many parents. It offers space for little ones to grow into their teenage years, eliminating the need to quickly upgrade to a larger mattress as they outgrow their twin.
  • Budget-conscious (or space-limited) couples – If you’re watching your spending or tight on space, you might be able to comfortably sleep together in a full-size bed. Just make sure this works with your individual sleep styles and preferences. You’ll be sleeping fairly close together throughout the night, so if either of you is prone to overheating, tossing or turning, or getting up frequently, you might want to opt for extra space.
  • Frequent hosts – If you’re looking to outfit your guest room with a new bed, full-size beds can be a great choice. They offer comfortable sleep accommodations for a solo guest (or a couple, if necessary), without taking up too much room.

Types of Bed Frames for Full-Size Beds

As you’re searching for full-size bed frames, you’ll quickly find a whole host of unique options.

These are the most common varieties of the full-size bed.

Panel Beds

A panel bed uses a series of horizontal slats, often wooden or metal, to form the central support system, which holds up the mattress. Panel beds are classic, versatile, and fairly common. Just keep in mind that you’ll need a mattress foundation or box spring to properly support your mattress on a panel bed.

Because the mattress lays right on top of the slats without much of a border, panel bed frames tend to be on the smaller side.

Platform Beds

A platform bed is a minimalist and modern bed frame design that typically forgoes a box spring, instead providing built-in support for your mattress. They have a solid platform base and, typically, a low profile, meaning they sit closer to the ground when compared to beds with a box spring.

Trundle Beds

Trundle beds are a space-saving solution that includes two beds in one: a standard bed frame is on top, and a lower wheeled platform fits underneath. When you pull out the bottom bed, it measures twice the size of a standard full, so make sure you keep this in mind when laying out a room with a trundle.

Sleigh Beds

Elegant and distinguished, sleigh beds are known for their curved headboard and footboard (reminiscent of a sleigh). Because of the elaborate head and footboard and sturdy wood, these frames are typically larger than some of the others on the list.


A daybed bridges the gap between a sofa and a bed. It functions as a couch and easily transforms into a sleeping space by adding bedding.

Loft Beds

A loft bed is another great option if you’re looking to save space. Think of a bunk bed without the bottom bunk—the bed is on a raised platform, which creates usable space beneath for a desk, couch, dresser, or other bedroom furniture.

Loft beds include stairs or a ladder and a more robust support system, so the total size of the frame is typically larger than a platform or panel bed.

Adjustable Beds

An adjustable bed has a motorized mechanism that allows you to change the head and foot section of the mattress, independently. This creates a customizable sleeping experience for optimal comfort and support.

With the added mechanisms attached to the bed, this style also tends to take up a bit more space than a minimalist frame.
