Plan a DIY garage workbench that fits your space
Garage Workbench Planner designs the classic 2x4 and plywood workbench — a frame of 2x4 rails and cross pieces, legs at the corners, a lower shelf and a thick plywood top — in three popular styles: a freestanding leg bench, a mobile bench on locking casters, and a wall-mounted bench on diagonal 2x4 brackets that leaves the floor clear. Build it straight along one wall or as an L-shaped corner bench, and add drawer banks, a pegboard or plywood back, and shelves or cubbies above. The 3D model, plans, cut list, lumber list and cost update as you type.
1. Measure your space
Wall length, how deep you can go, and the ceiling or window height if you want shelves above.
2. Pick a style
Leg bench, mobile bench or wall-mounted — straight or L-shaped. Add drawers, a lower shelf, pegboard and shelves.
3. Check the estimates
The fit check estimates what the top can carry, checks casters and wall brackets, and flags anything that won’t fit. Estimates only — build with care.
4. Build it

Frequently asked questions
How tall should a garage workbench be?
34 to 38 inches suits most people standing. A good rule is the height of your wrist with your arms hanging down; go a little lower for heavy hand-tool work and a little higher for detail work. On casters, the wheels count toward the height.
How deep should a workbench be?
24 inches is the most common because a 4x8 sheet of plywood rips into two tops. 30 inches gives more room for big projects; much deeper and the back is hard to reach — and wall-mounted brackets get heavily loaded.
What is the best top for a DIY workbench?
Two layers of 3/4″ plywood glued and screwed together is cheap, flat and stiff. A 1/4″ hardboard skin on top can be replaced when it is worn out. Butcher block is beautiful and very stiff but costs several times more.
How far apart should the legs be?
With 2x4 rails on edge front and back, legs up to about 6 feet apart carry a few hundred pounds comfortably. Longer benches get a middle pair of legs — the planner adds them automatically and estimates the capacity of each span.
Can I build a wall-mounted workbench?
Yes. Choose the wall-mounted style: a 2x4 ledger and diagonal 2x4 brackets, each lagged into a wall stud, hold the top with the floor left clear. Keep brackets on studs (every 16″ or 32″) and keep the depth reasonable.
Is the Garage Workbench Planner free?
Yes. It runs in your browser with no sign-up, and you can download the plans as a PDF or save your settings to a file.
