Twin size bed plan
Bill of materialsThe bill of materials below assumes all the lumber is good. You should buy extra lumber to be able to leave out pieces with defects in them. In general, its best to buy wider pieces of lumber and rip them into narrower pieces, such as buying 2x6 and ripping the 2x3's out of them. You get much better lumber that way. It may be better to buy five 2x10x8' instead of the parts marked with an asterisk, and cut everything from those.
Cross sectionNote how the slats rest on the ledge on the inside of the side rails.
Headboard assemblyThe holes for the dowels are best drilled by clamping the headboard and post together, and drilling the hole all the way through from the outside, as shown in the diagram below
Footboard dimensionsThe foot board is nearly identical to the headboard. If you are one of those people who prefer to stick their feet off the end of the bed, leave off the top horizontal part, and make the uprights just 18" long.
Bed railsThe bed rail has a series of blocks on the inside corners. The purpose of these is to space out the slats, and keep them from sliding around.
Its best to glue and screw the 1.5"x1.5" support for the slat onto the main part of the rail, to ensure
that its attached solidly.
AssemblyBed frames in general are designed to be disassembled for moving. For this bed frame, unscrewing the side rails will do the trick.
The slats are placed between the bed rails, and are only held in place by gravity. The blocks on the bed rails prevent them from sliding around.
