What you need

8 - 8 foot long 2x4s, do not cut
2 - 12 foot long 2x4s, cut in half exactly
3 - 8 foot or stud length 2x4s, use these boards to cut the 21" long pieces
2 - 1/2" sheets of plywood, cut in half lengthwise
100 - 3" self tapping star bit screws
40 - 1-3/4" self tapping star bit screws

Extra support - 2-6 1x4 boards, 72" long and additional 1-3/4" screws

TIP: For lighter weight, easier to build shelving, use the light toned pine or spruce 2x4s. For heavier duty shelving with better moisture control, look for red toned 2x4 boards

Step by step

Step 1

Find a flat, level surface to build the shelving. Mark the location of the joints, remembering the 2x4s are 3-1/2" wide. Lay out the legs and the long supports. Attach with 3" screws, so the frame pieces are all flush on the bottom. Repeat to build two identical.

Step 2

Join the two frames together with the 21" pieces, using two screws per joint. Reinforce the corner joints with additional screws into the long supports.

Step 3

Place the 1/2" plywood on top of the shelving. Screw down, using the plywood to square up the shelving, with 1-3/4" screws.

Step 4

For heavier loads, add 1x4s as shown to support the center of the shelving.

Finishing

Sand all surfaces, starting with a medium grit and finishing with fine. Wipe off the dust, fill any holes or gaps with wood filler, and sand smooth once dry. Apply primer if you're painting, then finish with your choice of paint or stain and seal with a durable clear topcoat. For outdoor projects, use exterior-rated primer, paint or stain, and sealer so the piece stands up to the weather.
