First of all, you need to understand that there are several designs to create a platform bed frame. Those are as below:


Full size mattress
Queen size mattress
King size mattress
Twin size mattress

For every each of above require you to have a different size of lumber in order to fit their sizes accordingly.

For twin size mattress you will need to have:
 

• one 4x8 foot sheet of particle board and cut to 40x76 inches,


• four of 1x12s and cut to 28 inches,


• four of 1x12s and cut to 62 1/2 inches,


• two of 1x4s and cut to 40 inches,


• and finally two of 1x4s to be cut to 77 ½ inches.

For Full size mattress
 

• two sheets of particle board cut to 38x55 inches,


• four 1x12s cut to 43 inches,


• four 1x12s cut to 62 1/2 inches,


• two 1x4s cut to 55 inches,


• and finally two 1x4s cut to 77 ½ inches

Queen size mattress
 

• two sheets of particle board cut to 40 ½ x 61 inches,


• four 1x12s cut to 49 inches,


• four 1x12s cut to 67 1/2 inches,


• two 1x4s cut to 61 inches, and

In building a platform bed frame, you will need two pieces of particle board together to be attached from the underside with a straight metal straps. One half will form the top platform and other half will be the bottom portion. Once this is completed, make sure you sand any rough edges on your lumber before you building the base frame.

And now you are ready to build the base frame for your platform bed. Firstly, build a rectangular box from four 1 x 12s by using wood screws. You sink the screws and cover the holes with wood filler. Make sure to attach the remaining long boards at 1/3 intervals within the frame.

Understanding this next process is important. You will need to measure the distance between each section and cut the remaining short boards into six pieces to attach at staggered intervals as shown in the drawing. See here to see what I mean. By doing this, it will creates a strong base that will not warp or twist.

Finally, what you need to do is to lay the particle board platform top-side down and center the base frame on the underside. In order for your to attach the base to the platform you use the metal L-brackets. Make sure you use two on each side. Until both side are already attached, flip the bed over and attach the 1 x 4s around the edge of the particle board platform with wood screws but remember to leave one inch lip above the particle.

As for the finishing part, paint your platform bed frame as how you desired. If a natural wood finish is desired, simply place a coat of polyurethane over the entire structure. This will stands out the natural wood color to shine.
