Converting a King to a Queen Size Bed

Quck answer

To convert a king size bed to a queen size bed, follow these steps:

1. Remove the king size mattress and bedding from the bed frame.

2. Measure the width and length of the bed frame to ensure it will accommodate a queen size mattress.

3. If the bed frame is adjustable, adjust it to fit the dimensions of a queen size mattress.

4. If the bed frame is not adjustable, you may need to purchase a new bed frame that is compatible with a queen size mattress.

5. Once the bed frame is adjusted or replaced, place the queen size mattress onto the frame.

6. Add queen size bedding and accessories to complete the transformation.

By following these steps, you can easily convert a king size bed to a queen size bed.


Converting a king size bed to a queen size bed is a simple modification that can be easily done. Queen mattresses have the same length as standard king mattresses, and bed rails are adjustable along the width. These instructions are specifically for converting basic, standard bed rail frames. If you have a solid wooden frame, it may be more difficult to convert and it might be easier to find a replacement frame instead.

Step 1

Inspect the bed rails. The bed rail assembly uses nuts, usually wing nuts, to attach the two halves together. The nuts go through holes that are drilled in the shorter sides of the bed frames. Some rails have multiple holes. Make sure that the smallest possible setting is wider than 60 inches, which is the width of a queen mattress. If the rails are already compatible with both queen and king mattresses, you can skip this step.

Step 2

Slide the rails together until the width of the frame is 60 inches. Mark both overlapping rails at two points where they overlap.

Step 3

Put on safety goggles. Drilling through metal creates sparks and metal slivers. If you are doing this in your bedroom, have a fire extinguisher nearby. There is a small but real risk that sparks can ignite your curtains, bedding, or carpet.

Step 4

Using a drill bit that has the same diameter as the bolts that come with the bed rail set, drill through the marked points on the rails.

Step 5

Reassemble the bed rails in the 60-inch wide position. Secure them in place by bolting them through the holes that you have just drilled.
