Guide to Bed Frame Dimension (with Detailed Drawings)

Bed Frame Dimension

Having the right bed frame is important to make sure that your mattress will last long. Remember, if your bed frame is too big, your mattress will slide around due to the gaps.

On the other hand, if your bed frame is too small, your mattress may bend or fold, resulting in indentations and sagging.

As such, knowing the various bed sizes is vital so that you’ll be able to buy the perfect furniture. So, what are the different bed frame dimensions?

What Is a Bed Frame?

What Is a Bed Frame?

A bed frame is a piece of furniture that supports your mattress, keeping your mattress off the ground where it can remain dry and clean. Typically, it is made of metal or wood. Additionally, it also has two side panels, a footboard, and a headboard. Oftentimes, it will also have a solid or slated base that supports your mattress.

Standard Bed Frame Height

Standard Bed Frame Height

First, you need to know that a bed height consists of a frame height and a mattress height. The standard mattress and box spring height is between 8 to 12 inches.

And most bed height (with a mattress) today is between 18 – 36 inches with 25 inches being the average today’s bed height. Antique beds are about 36 inches in height while modern platform bed is around 18 inches high.

So without a mattress, the average bed frame height should be around 7 – 18 inches from the floor.

Standard Bed Frame Width and Length

The difference is that the twin XL is longer by about five inches, making it a great bed for tall adults who don’t have enough space for a bigger bed. Aside from that, this piece of furniture is common in college dorm rooms because its additional length can accommodate any height.

Keep in mind that a twin XL is a rare size, especially when it comes to bed sheets and comforters. For this reason, you have to double-check the size to make sure you’re buying the right bedding.

A full-sized bed frame is also known as a double bed. It has a dimension of about 54 inches by 75 inches; thus, it is about 16 inches wider than a twin bed.

A full-sized bed frame is suitable for restless sleepers who move a lot while sleeping. Additionally, this piece of furniture is a popular choice for single adults who live in a studio apartment. Couples may also opt for this bed size; however, it is not recommended, especially if they share the bed with their child or pet.
