Join together two twin beds to make an inexpensive king size bed. (twin beds image by dbvirago from

A standard king size bed, or Eastern King, is 76 inches wide by 80 inches long. A regular twin bed is 39 inches wide by 75 inches long, while an extra-long twin bed is 80 inches long. You can create a roomy king size bed inexpensively with two twin beds placed side by side. Hold the beds securely together with a ratchet strap or buy a bed-joining kit. Although the overall dimensions are slightly different, all standard king size bedding will fit the double-twin bed.

  1. 1

    Remove the bedding from both twin beds, if necessary.

  2. 2

    Push the twin beds together, side by side, with the top and bottom edges aligned

  3. 3

    Wrap the ratchet strap around the outside of both mattresses and hook the ends together. Tighten the ratchet to hold the mattresses snugly in place.

  4. 4

    Roll up a twin size quilt batting lengthwise, starting at one side. Press the roll halfway into the crack between the mattresses. Press down the top of the quilt batting roll to create a flattened padded strip over the full length of the crack.

  5. 5

    Place the king size mattress pad on the joined twin mattresses.

  6. 6

    Place king size sheets on the newly-created king size bed.

Tips and warnings

  • When using regular-length twin beds, place the box springs horizontally and the mattresses vertically to keep the beds from separating further.
  • For added comfort, put a foam mattress topper under the mattress pad.
  • Buy a Create-a-King, Extend-A-Bed or other mattress joining system instead of making your own with a ratchet strap and quilt batting, if desired.
  • Do not try to combine twin beds on frames with side rails.
