A bookcase is one of the best first furniture projects. The joints are simple, the parts are rectangular, and the result is immediately useful. This design uses a single sheet of 3/4-inch plywood, produces a five-shelf bookcase roughly 72 inches tall by 32 inches wide by 11.25 inches deep, and costs under $70 in materials. You need a circular saw or table saw, a drill, and basic measuring tools.

Build a Simple Bookcase

Materials

One 4x8 sheet of 3/4-inch plywood (birch or maple for paint, walnut or oak for stain)
One 4x8 sheet of 1/4-inch plywood (for the back panel)
Iron-on edge banding (25 feet, matching the plywood species)
Wood glue
1.5-inch brad nails or 1-5/8-inch finish screws
Sandpaper (120 and 220 grit)
Paint or stain and finish

Total materials cost: $50 to $70

Cut List

From the 3/4-inch plywood sheet:

Part	Quantity	Dimensions
Sides	2	11.25” x 72”
Top	1	11.25” x 30.5”
Bottom	1	11.25” x 30.5”
Fixed shelves	3	11.25” x 30.5”
Toe kick (optional)	1	3.5” x 30.5”

From the 1/4-inch plywood:

Part	Quantity	Dimensions
Back panel	1	32” x 72”

The shelf length (30.5 inches) accounts for the two side panels (each 3/4 inch thick) fitting inside a 32-inch total width. Verify this math against your actual plywood thickness — it varies by manufacturer.

Cutting the Parts

Using a table saw: Rip the plywood to 11.25-inch width first (two long rips from the 48-inch dimension). Then crosscut the shelves, top, and bottom to 30.5 inches on the miter saw or with a crosscut sled.

Using a circular saw: Clamp a straightedge guide (or use a track saw) and make the rip cuts on the factory floor with the sheet on foam insulation board. Accuracy matters — a crooked side panel makes the entire bookcase crooked.

Label every part with painter’s tape after cutting: left side, right side, top, bottom, shelf 1, shelf 2, shelf 3.

Edge Banding

The front edges of plywood shelves and sides show the laminated plies. Cover them with iron-on edge banding before assembly:

Cut the banding 1 inch longer than the edge
Place it on the plywood edge with the glue side down
Run a household iron (cotton setting) slowly along the banding. The heat activates the adhesive.
Press the banding down with a roller or block of wood while it is still warm
Trim the overhang with an edge banding trimmer ($8) or a utility knife and sand flush with 220-grit sandpaper

Apply banding to all visible front edges: side panels, shelves, and top. The bottom edge is optional if the bookcase sits on a toe kick.

Assembly

Laying Out Shelf Positions

Mark the shelf positions on the inside faces of both side panels. Equal spacing for five openings on a 72-inch bookcase works out to roughly 13 to 14 inches between shelves, accounting for the shelf thickness and the toe kick.

Mark positions measuring from the bottom:

Bottom panel: 3.5 inches up (top of the toe kick area)
Shelf 1: 17.25 inches
Shelf 2: 31 inches
Shelf 3: 44.75 inches
Top: 71.25 inches (3/4 inch down from the top)

Adjust spacing based on what you plan to store. Taller shelves for art books and binders, shorter shelves for paperbacks. There is no rule that says shelves must be equal.

Joining Shelves to Sides

For a simple and strong joint, use pocket hole screws from the inside:

Drill pocket holes along each end of the shelves, top, and bottom — two holes per joint at minimum, three for long shelves.
Apply a thin line of wood glue to the end grain of the shelf.
Clamp the shelf at its marked position on the side panel.
Drive pocket hole screws through the shelf into the side panel.

Alternative: dado joints. Cut 3/4-inch wide, 3/8-inch deep dados across the inside of each side panel at each shelf location using a router and straight bit or the table saw with a dado blade. Slide the shelves into the dados with glue. Dados are stronger and hide the joint completely, but require more setup time and a confident router or dado blade technique.

Alternative: screws from outside. The simplest method. Pre-drill and countersink through the side panel into the shelf end. Drive 1-5/8-inch screws. Fill the countersinks with wood putty. This is perfectly structural but shows filled holes on the side panels. Fine for a painted bookcase or a workshop utility shelf.

Assembly Sequence

Lay one side panel flat on the floor (inside face up)
Attach the bottom panel, then shelves from bottom up, then the top
Attach the second side panel onto all the shelves, flipping the assembly upright

Have a helper hold the second side while you drive the pocket screws or screws. Clamps on a flat surface help hold everything square during assembly.

Back Panel

The 1/4-inch plywood back panel provides critical rigidity. Without it, the bookcase racks from side to side and eventually collapses.

Check the bookcase for square by measuring the diagonals. If both diagonal measurements are equal, the case is square. If not, rack it gently until they match.
Apply glue to the back edges of the sides, top, bottom, and shelves.
Set the 1/4-inch panel on the back and nail it in place with 1-inch brads every 6 inches along the sides, top, bottom, and every shelf.

The back panel locks the case square permanently. Do not skip it.

Toe Kick

A 3.5-inch tall toe kick strip across the front bottom provides a recess for your feet (so you can stand close to the bookcase) and hides the bottom edge of the side panels. Glue and nail it between the side panels, inset 2 inches from the front edge.

Finishing

For paint: Sand all surfaces with 120-grit, then 220-grit. Prime with a shellac-based primer (Zinsser BIN or similar). Sand lightly with 220 after primer dries. Apply two coats of semi-gloss or satin latex paint. Sand between coats with 320-grit.

For stain: Sand all surfaces through 220-grit. Apply wood stain evenly with a rag. Wipe off excess after 5 to 10 minutes. Apply two to three coats of water-based polyurethane, sanding with 320-grit between coats.

Wall Anchoring

A tall bookcase loaded with books is a tipping hazard, especially in homes with children. Anchor it to the wall with a furniture anti-tip strap or drive a screw through the back panel into a wall stud near the top. This is not optional for a 72-inch bookcase — it is a safety requirement.

Bottom Line

One sheet of plywood, pocket hole screws or dados, edge banding, and an afternoon of work produces a solid bookcase that holds hundreds of pounds of books. It is a project that builds cutting, assembly, and finishing skills while producing furniture you actually use every day. Build one, then build three more — every room needs shelves.
