Make This Adorable DIY Kids Bookshelf | Perfect for Bedrooms & Storage!

What you need
Adult supervision required, clamps, hand saw, l-brackets, level, measuring tape, pencil, ruler or square, sandpaper, screwdriver or drill, screws, wall anchors, wooden board

Step 1

Gather all the materials on a clear table so everything is ready to use.

Step 2

Decide how long you want your shelf to be and mark both ends on the board with your pencil.

Step 3

Use the ruler or square to draw a straight cutting line across the board at your marks.

Step 4

Clamp the board securely to the work surface so it will not move while you work.

Step 5

Ask an adult to cut the board along your line with the hand saw.

Step 6

Sand the cut edge and the top surface of the shelf with sandpaper until they are smooth to the touch.

Step 7

Position the L-brackets where the shelf will sit and mark each bracket screw hole with your pencil.

Step 8

Ask an adult to pre-drill small pilot holes where you marked for the screws.

Step 9

Attach the brackets to the shelf by driving screws through the bracket holes into the pilot holes.

Step 10

Hold the shelf against the wall where you want it and use the level to mark where the bracket holes will go on the wall.

Step 11

Ask an adult to install wall anchors at your marks and fasten the shelf to the wall using the brackets and screws.

Step 12

Share your finished shelf on DIY.org

Help!?

What can we use if we can't find L-brackets, wall anchors, or a hand saw?

If you can't find L-brackets, wall anchors, or a hand saw, ask an adult to pre-cut the board to your marked length at the hardware store and substitute corner braces for L-brackets and long wood screws into a stud instead of anchors while following the 'Position the L-brackets' and 'install wall anchors' steps.

The shelf feels wobbly or comes out uneven after installing—what should we check or fix?

If the shelf is wobbly or uneven after installing, loosen the bracket screws, hold the shelf against the wall with the level as in the 'Hold the shelf...' step, use thin shims behind brackets if needed, then retighten screws into the anchors.

How can we change the steps to make this activity safe and fun for younger kids or more challenging for older kids?

For younger kids have an adult pre-cut, clamp, and pre-drill the board while the child sands, marks bracket positions, and decorates the shelf, and for older kids let them measure, draw the cutting line, clamp the board, assist with the saw, and install brackets and anchors with adult supervision to practice the full steps.

What are simple ways to personalize or upgrade the finished shelf before sharing it on DIY.org?

To personalize the shelf, sand and paint the board after the 'Sand the cut edge' step, add a decorative trim or small front lip before attaching the brackets, and attach adhesive LED strip or hooks underneath after installation to showcase items.

Facts about woodworking for kids

🧽 Sandpaper grit numbers tell you how coarse or fine the abrasive is—higher numbers mean a smoother finish.

🪚 Saws have been used for thousands of years—archaeologists have found Bronze Age saws over 3,000 years old.

📏 The small metal hook on a tape measure is designed to move so you get accurate inside and outside measurements.

🛡️ Wearing safety goggles and using clamps are two simple habits that greatly reduce common workshop accidents.

🪵 Wood swells and shrinks with humidity, so lumber often changes size a few percent as it acclimates to a room.

How do you build a simple wooden shelf with a child?

Start by drawing a simple plan and measuring the desired shelf width and depth together. Have an adult mark and cut the boards with a saw, or cut pieces beforehand. Let the child sand edges, test-fit pieces, and apply wood glue. Use clamps while an adult drills pilot holes and inserts screws to assemble. Finish by sanding, then painting or sealing. Keep instructions clear, work slowly, and explain each step to teach basic carpentry and safety.

What materials and tools do I need to build a simple wooden shelf safely?

You’ll need wood boards (plywood or pine), a measuring tape, pencil, carpenter’s square, sandpaper (various grits), wood glue, screws, clamps, and a drill with screwdriver bit. Optional: paint or stain and brushes. For cutting, use a handsaw or jigsaw; power tools should be handled by an adult. Safety gear: safety glasses, hearing protection for adults using power tools, and work gloves. Pre-cut pieces if you prefer less tool work for kids.

What ages is this wooden shelf activity suitable for?

This activity suits different ages with appropriate roles: toddlers (3–5) can help measure, hold a pencil, and paint under supervision; elementary kids (6–9) can sand, clamp, and assist with simple screwing using a manual screwdriver; older kids (10+) can learn to mark cuts and watch an adult cut with power tools, possibly try supervised handsawing. Always match tasks to a child’s motor skills and keep close adult supervision for any cutting or drilling.

What safety tips and benefits should I know when building a shelf with a child?

Safety: always wear eye protection, keep long hair and loose clothing secured, and use clamps to steady wood. Adults should handle power tools and sharp blades while explaining hazards. Teach tool rules (one tool at a time, think before you act). Benefits: hands-on carpentry builds fine motor skills, measuring/math practice, problem solving, and confidence. Consider pre-cut kits or simplified designs to reduce risk while keeping learning and fun.
