Some people put two twin beds together in the hopes of making one larger bed. It’s especially useful if two people want to share a bed but do not have a single large bed, or mates who want to sleep together but prefer different types of mattresses. However, where the two twins connect, it may not be delightful to sleep on.

When choosing a bed, one of the most important factors to consider is the size of the bed. Mattress sizes, like king, queen, and twin, do you really know the difference between them and how big they are?

How wide is a twin bed?

First things first, let’s talk about the dimensions of a twin bed. By standards, a twin mattress, or also called “single,” is the smallest possible mattress size other than a crib-size mattress. Twin dimensions are approximately 38 inches wide by 75 inches long.

If you add another twin bed to the equation, that will equal about 78 inches in width, approximately. This is a lot larger than a queen size bed, which is only 60 inches wide.

A queen size bed is approximately 60 inches wide by 80 inches long, so it is also longer than a twin. As a result, if you attempt to put a queen-sized comforter onto two twin size beds, the sheets will be too narrow, but also too long: They will not reach the sides of the beds and also will hang over the foot of the bed and pile onto the floor.

In short, putting two twins together would be 16 inches wider and 5 inches shorter than a queen mattress.

Do Two Twins Make a King?

The next question, perhaps, will be: “Do two twins make a king?” If so, how to turn two twin beds into a king?

A king comforter or sheet works a little better for covering two joined twin beds. A king mattress is 76 inches in width and 80 inches length. As a result, the king size is just two inches small in width than two combined twin mattresses. Yet, like the queen size, the king is going to have six inches extra of length. This might mean that the bedding, like the comforters, sheets, or covers, exceeds the foot of the bed.

What Do Two Twin-Size Mattresses equal?

King size bed better is your best bet when attempting to cover two joined twin beds. Because a lot of bedding is not standardized in size, you can find slightly wider king bedding that should work great. Different brands will have slightly different widths.

The critical thing to remember is that two twin beds add up to 78 inches in width. The actual size is somewhere between a king size and a queen size.

Another option to fit that 6 inches extra in length, there is another standard bed size. That is the twin extra large. What are two twin XL beds equal?

The Twin XL is 6 inches longer than the standard twin mattress to provide more length for a grown adult. That solves the solution, but this size is difficult to find.

How To Convert Two Twin Beds To A King?

Verify Your Frame Width

The first thing you need is the king size mattress platform. It’s essential to measure your bed frame or platform to verify the mattresses will fit.

Then, before placing the mattresses, I recommend putting a rubber non-skid rug pad, so that it won’t slipper – remember that the mattresses would slide a few inches away from the headboard, and they might try to escape onto the floor.

Bridge the Gap

As mentioned in the beginning, it is not comfortable to sleep in the middle of both mattresses. To solve that, fill the gap between the two twin mattresses with a foam bed bridge. It isn’t going to make the top of your bed completely seamless, but it fills the gap pretty well and provides an even sleep surface. It does create a smooth raised area in the middle of the bed, but it’s not uncomfortable. And, of course, don’t sleep directly in the middle of the bed.

Extra additions and ideas

As an addition, a mattress pad might be a good idea. It gave new life to the older mattresses, so it might help disguise the bed bridge. Additionally, with a thick mattress pad, king size sheets fit perfectly on the mattresses without having too much slack. So the thick pad works for two main purposes: the bed will be comfier and helps the sheets fit better, remember the 5 inches extra..

Finally, compensate for the short length of regular mattresses with an upholstered headboard. Just pulled the mattresses all the way down to the end and then put the headboard there.

What Size Sheets for Two Twin Beds Pushed Together?

For two twin size beds together, you are going to be hard-pressed to find sheets that fit. A standard twin bed is 38 inches wide and 75 inches long; a standard King bed is 76 inches wide and 80 inches long. However, if you use Twin XL beds, you can push them together and use king-sized sheets.

Two twins combined make a king size, but not just any twins will do. A standard king-size mattress is 76 inches wide and 80 inches long. And while it would be easy to put two standard twin mattresses together simply, this presents a problem: you’ll end up with a perfect fit width-wise, but the bed will be a whopping 5 inches shorter in length.

The easy solution to this problem is to use two XL twin size beds, which, at 80 inches in length, will be precisely the same length as a king size bed. This means any standard king size sheets and bedding will be a perfect fit, and no one’s feet are left to dangle.
