Do Two Twins Make A King? A Guide To Making A King Bed Out Of Two Twins

Two twins can’t make a king-size bed perfectly. Because a king is 80 inches long, while a twin is 75 inches long. Ultimately, while the width of two twins makes the width of a king, the length remains shorter.

Nothing to worry about, though! You can still make a king out of two regular-sized twins measuring 38 inches by 75 inches. But how do two twins make a king? And what mattress size makes a solid king bed?

In our guide, you can learn about all this, plus which is better between two twins and a king bed. So, let’s get to the point without further ado. 

Two Twins And A King Measurements Comparison Table

Do Two Twins Make A King?

Do Two Twins Make A King?

Not completely. This is because a standard king-size mattress measures 76 inches wide and 80 inches long. Meanwhile, a standard twin bed is 38 inches wide and 75 inches long.

This means two twin-size mattresses would be 76 inches wide and 75 inches long. While the width remains the same, the length of the two twin beds would be shorter than that of a king bed by 5 inches.

Although two twins don’t make a traditional king bed, this can still work if the sleepers are at most 6 feet.

How To Make A King Bed Out Of Two Twins?

So, considering their shorter length, how do you make a king bed out of two regular twins? Here is a step-by-step guide on how to do it.

Step 1: Set Up the Platform Bed Frame

Instead of a box spring, set up a king-size platform bed which is more durable and less expensive.

Then, place a non-skid rubber pad on the platform bed to prevent the twins from sliding off. Lastly, add a bed skirt (optional) to conceal the underside of your bed.

Step 2: Combine the Twins on the Platform Bed

Next, get your standard twin-size mattresses and place them side by side on the platform bed. After that, bridge the gap between the mattresses using a foam bed bridge or any foam fillers. This will ensure you get a uniform sleeping surface.

Step 3: Add a Mattress Pad or Topper

To create an even more sleeping surface, add a mattress pad or a mattress topper for enhanced deep sleep. The pad should cover the two twins, ensuring your king-size bedding fits perfectly with little or no slack. Therefore, you won’t need to invest in extra-deep fitted sheets.

Step 4: Make Up For The Short Length

Your two twins will be 5 inches shorter than the length of your king-size platform bed. Therefore, you will end up with a gap at the foot or head of your bed.

Pull the twins down to the end of the platform bed to make up for this short length. Then, fill the gap between the wall and the bed using an upholstered headboard.

You can make your own headboard if you are a DIY person or buy one. And that’s it; you now have a king-size bed made from two twins. Lastly, add the bedding.

What Makes A Perfect King Bed?

If you want a perfect king bed, get two twin XL mattresses rather than standard twins. This is because a twin XL mattress measures 38 inches wide and 80 inches long. The length is equal to a king’s.

In such a case, this is called a split king. You can choose different firmness for the two different twin XL, which is a great advantage for many people.

But, of course, you must use foam filler to bridge the gap between the beds.

Are Two Twins/Twin XL Better Than A Solid King?

Yes, two twins/twin XL are better than a solid king for several reasons. Here are the reasons behind this.

Ease of Customization

Compared to a regular king-size mattress, two twins make it possible to customize the bed based on the needs of each sleeper. This is because you can choose two twins with varying firmness levels. Besides, if one partner sleeps cold, they could add an electric heater on their twin alone.

Effortless to Carry and Move

A king-size mattress is heavy and more oversized than a twin XL. As such, it can take a lot of work to move it around, especially up the staircase. However, it is easier to handle two twins/XL separately, even alone.

Relatively Cheaper

The beddings are more affordable if you use twin/twin XL rather than king-size due to their size. So, you get to enjoy the luxury feeling of a king bed without spending a lot.

Personal Space

If you don’t like to cuddle, two twins/XL are the best. The twins provide you with personal space since the other sleeper cannot easily roll into your side.

Frequently Asked Questions

No, two twin mattresses do not make a queen-sized mattress. Twin mattresses and queen-sized mattresses are two different sizes and cannot be combined to create a queen-sized mattress.

It’s best to choose a mattress that is the appropriate size for your needs rather than trying to combine two smaller mattresses to create a larger one.

Two twin beds placed together will make a king-size bed. Twin beds, also known as single beds, are typically 38 inches wide and 75 inches long, while a king-size bed is 76 inches wide and 80 inches long. Two twin beds placed side by side will give you the width of a king-size bed but will be shorter in length.


Two twins won’t make a traditional king bed because of their short length. Instead, you can use two twin XL. You can still have a king-size bed using two regular twins with a little customization.

You just add an upholstered headboard to compensate for the shorter length. And with all the benefits two twins offer, they are way better than buying a standard king bed.
