What Size Bed Do Two Twins Make And How

Do two twin size mattresses equal a king size mattress?

What size bed do two twin beds make? When you put together two twin-size mattresses, they almost make a king-size bed. Why do we say almost here? Because the twin bed dimensions are 38 X 75 inches while a king measures 76 X 80 inches. So, when two twins come together, collectively, the bed dimensions become 76 X 75 inches. While the width matches a kings, it falls 5 inches short in length.

This can work perfectly well for you if you are someone who doesnt need the extra length or are not on the taller side. With two twin beds together, you can experience the same width as a king, which means more space for you and your partner. So, do two twins make a king-size bed? Yes, when it comes to the width and almost when it comes to the length.

Fix Both Mattresses It With A Bridge

The first step is to join the beds and fix them using clamps. And this is important if you permanently want to convert it into a king bed.

However, if you only want a temporary solution, using a bridge will do.

The foam bed bridge helps fill the gap between two mattresses to connect them and make them smooth for use.

Fix the bridge with the help of a belt and fill the gap to have an even surface between the 2 beds.

We recommend using the bed bridge converting kit from Bedia as it is a full kit that includes both the bridge to connect the twin beds and the strap to

While this first step is not mandatory, it is definitely recommended as it fills the gap, makes both beds connected to each other, and eventually makes you feel more comfortable while sleeping.

Start With Two Twin Xl Mattresses

Two twins make a king, but not just any twins will do. A standard king size mattress is 76 inches wide and 80 inches long. A standard twin bed is 38 inches wide and 75 inches long. And while it would be easy to simply put two standard twin mattresses together, this presents a problem: Youll 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 conundrum is to use two XL twin beds which, at 80 inches in length, will be exactly the same length as a king size mattress. This means any standard king size sheets will be a perfect fit and no ones feet are left to dangle.

    King And California King

    With two sizes of king beds and four names, it can get confusing when you go shopping for a king-size bed. A standard king is also called an Eastern king and a California king is also called a Western king. A standard king is about 4 inches wider but shorter than a California king, and a California king is 4 inches longer but narrower than a standard or Eastern king.

    Two people sleeping in a king-size bed will get the same amount of personal sleeping space as in a twin bed. In fact, if you pushed two extra-long twin beds together, they’d be about the same size as an Eastern king. For great versatility in a guest room, if you have the floor space, you can use two extra long twin beds separately for singles or push them together to make a king bed for couples.

    When buying sheets, you have to be careful to purchase the right size. Flat sheets will fit both sizes of king beds, but fitted sheets are cut to fit one or the other. Before you go shopping for sheets, be sure to measure your bed exactly to be sure to buy the linens that will fit.
