A twin mattress measures 38 inches wide by 75 inches long. A king-size mattress measures 76 inches wide by 80 inches long. Placed side-by-side, two twin mattresses measure 76 inches wide by 75 inches long – five inches shorter than your typical king-size bed.

Combine The Two Twin Mattresses
Once your base is set, lay both mattresses on the frame(s) side by side.
Before buying your beds, always make sure that you purchase mattresses of the same thickness. This will ensure that your mattresses line up when placed next to each other.
The same goes for your bed frame. If you’re purchasing separate twin or twin XL frames, be sure to check the height of the frames beforehand.
Minimize The Middle Gap
Sometimes, placing two mattresses side by side creates a small gap which often proves to be a nuisance. To close the gap, you can find specially made foam fillers or bed bridges designed for this purpose.
Make The Surface Level
Foam fillers can make the mattress feel a little lumpy in the middle, especially around the gap. To remedy this, consider using a mattress topper or mattress pad. The added padding will mask the feeling of the pesky wedge underneath.
Secure The Mattresses
As mentioned, two mattresses can be secured with a strap or a metal bar that locks them in place. This will ultimately prevent slippage and keep you and your partner comfortable throughout the night.
Cover The Mattress With Sheets
Since two twin XLs are equivalent to a king-size mattress, you can use king-size beddings for your bed. Grab a king-size comforter or duvet and some pillows, and you’re all set for a good night’s sleep!
