Finding The Right Bed Frame

Unless you’re a college student on a low budget or you’re going for an extreme bohemian hippie bedroom vibe, most of us prefer to keep our mattresses off of the floor. That’s where a bed frame comes in; it’s a solid surface, with or without legs, that supports and holds your mattress up off the ground. You can find a bed frame in almost any look or style from contemporary to Victorian, and they’re available in a range of different prices too. You just want to ensure you choose the most appropriate bed frame that fits both your mattress and living space.

If you’re on the hunt for a bed frame that fits your current bed, start out by measuring its length and width. This will give you a good idea on how big you want your new bed frame to be, as standard bed frames are approximately the size of the bed they’re built to accommodate. Unless the frame is designed to be longer and wider like some platform bases are, your bed should take up the entire surface of the frame.

For those of you shopping for a mattress and a frame, you should first decide how big you want your frame to be. Do you have a specific wall you want to fit it against? How much space do you have in your bedroom? Does it also need to fit in between two nightstands? Once you measure out the amount of space you have to work with and configure a rough floor plan outline, go ahead and make a decision on the size of bed you want.

As a pro tip, add about 2” – 5” to your mattress measurement to estimate the amount of space your future bed frame might take up. This is to account for the extra materials your bed frame may come with, like mine (Slumber Yard member McKenzie Dillon), the Lucid adjustable base, which is constructed with an additional 1”-2” of gray padding around the frame’s perimeter. With that being said, you should also be able to find your future bed frame’s exact length and width on the site you purchased it from.

If you’re interested in a bed frame equipped with extra features like drawers, cabinets, headboard, or footboard, it’s important that you check the description box for exact measurements. Since there are such a wide range of different bed base options out there, we can really only give you figures on average bed frames, especially since extra features can drastically add to a bed frame’s measurements.

What Are The Dimensions Of A Twin Size Bed Frame?

A twin sized bed, also known as a single bed, is most ideal for a children’s bedroom, but it’s also commonly used for guest bedrooms that are meant to accommodate more than one person because it doesn’t take up a ton of space. A standard twin size bed frame is approximately the same width and length as a twin bed which is typically around 38” x 75”, but like we mentioned before, some may have another 2”-5” or so extra in length and width because of additional material.

There are also twin XL mattresses and twin XL bed frames, which are most popular for college students in dorm rooms. Twin XL beds are the same width and twin beds, but are about 5” longer. Twin XL bed frames are around the same length as a twin XL mattress, plus another 2”-5” more depending on the frame.

Length And Width Of A Full Size Bed Frame?

Full size mattresses are most popular in teens’ bedrooms or for single adults who are trying to be space-conscious. It may not be big enough for two adults, however, unless they’re both real big on cuddling.

full size bed is about 53” wide by 75” long, so you can assume a full size bed frame is around a few inches wider and longer.

What About A Queen Size Bed Frame?

This is where we get into the adult and couple mattress realm, as a queen sized mattress is perfectly suitable for couples and or your average man or woman. It’s actually the most popular bed size on the market, and according to our own research, over 50% of our own audience sleeps on a queen mattress.

A queen size is not the biggest bed you can get your hands on, but it fits two people comfortably without taking up all of the space in your bedroom. A run-of-the-mill queen size bed frame measures out to be — you guessed it — 2”-5” more than a queen size mattress which is 60 wide by 80” long.

King Size Bed Frame Dimensions

King size mattresses are most commonly used by adult couples, and really tall individuals like our Slumber Yard resident tall-man JD who’s 6’5 and hangs off the edges of anything smaller than a king bed. A king size bed is 76” wide and 80” long, so an average king size bed frame might be in the ballpark of 81” x 85”.

Like we mentioned before, you’ll want to double check the frame’s exact measurement when you eventually narrow down your mattress foundation choices.

How Wide Is A Cal King Bed Frame?

If you want to be livin’ large on an extra long mattress, a California king bed and bed frame may be the perfect options for you. Some are under the impression that a Cal king bed is bigger than a standard king in both length and width, but a standard king is actually wider. Instead, a Cal king has the one-up in length, and measures out to be 72” wide and 84” long. If these figures aren’t already drilled into your brain, your future standard Cal king bed frame will probably be around 2”-5” bigger than the bed.
