This online desk configurator helps you sketch a full writing or computer desk, place left and right modular blocks with drawers or open bays, select an over-hutch style, pick materials and finishes, and instantly preview a 3D model and shop drawings. You get quick material takeoffs, a simple cutting spec, and measurements you can use for estimating and shop work. It runs in the browser on phones and desktop with no install required.

Why you’d use it
- Quickly check proportions and layout before you cut anything.
- Estimate tabletop area, cabinet volumes, and board footage.
- Produce two basic elevations for cutting and assembly: top view and side view.
- Experiment with moving a right module or left module, try different drawer counts, and test several hutch styles.
How to use the designer
- Enter the tabletop width in millimeters. This is the overall outside width of the desk.
- Set the tabletop depth. That is the usable work surface depth.
- Set desk height from floor to top surface in millimeters.
- Define right and left module widths in millimeters. Modules start from the side panels and extend inward.
- Choose block types for each side: none, single door, pull-out shelf plus door, two-drawer stack, three-drawer stack.
- Pick a hutch style: simple shelf, enclosed hutch with doors, open cubes, or a rear panel only.
- Pick colors or upload a texture image to preview veneer or laminate on the model.
- Preview the 3D model. Use the Download button to export a PNG snapshot containing the 3D view and the two projections.
Practical build rules and clearances
- Typical panel thickness. Tops use 18 to 36 mm. Case panels and drawer fronts use 16 to 24 mm. Thinner panels save weight but lose stiffness unless you add stiffening rails.
- Front gaps. Leave 1.5 to 3 mm between drawer front and case for smooth operation.
- Handle projection. Exposed handles usually stick out 6 to 12 mm. Recessed pulls reduce that dimension.
- Drilling and dowel allowances. For dowels allow +0.2 to +0.5 mm fit; for confirmat screws use recommended diameter and embed depth from the hardware vendor.
- Box depth. Interior boxes are slightly shallower than the tabletop so the drawer runners and front clearance fit cleanly.
Formulas and quick calculations
| Calculation | Formula |
|---|---|
| Tabletop area | A = (W mm / 1000) × (D mm / 1000) m² |
| Top volume | V_top = A × (T mm / 1000) m³ |
| Single case box volume | V_box = (W_box / 1000) × (D_inner / 1000) × (H_box / 1000) m³ |
| Total trim/plank length | L_total = sum of all cut lengths in meters |
| Estimated wood mass | m ≈ V_total × ρ where ρ is wood density in kg/m³ |
Material references
Common woods and typical density
| Species | Density kg/m³ | Notes |
|---|---|---|
| Pine / Spruce | 430–550 | Lightweight and affordable for simple builds |
| Birch | 650–700 | Good strength and finish |
| Oak | 700–900 | Durable, great for wear resistance |
| Ash / Alder | 600–750 | Flexible with attractive grain |
Fastener and hardware guidelines
| Item | Recommendation |
|---|---|
| Wood screws | 4×30 to 5×60 mm for carcass joints |
| Dowels | 8–10 mm diameter, 30–50 mm length for hidden joints |
| Confirmat screws | 6.3×50 mm for panel-to-panel assembly |
| Drawer slides | Full extension, 350–500 mm length by drawer depth |
Workshop workflow
- Material check. Verify panel flatness and moisture content before cutting.
- Layout and cut. Follow the cutting list, allow extra stock for edge trimming.
- Assemble boxes. Put carcasses together first, then add dividers and drawer boxes.
- Fit hardware and fronts. Adjust gaps, test drawer movement.
- Join top to supports and fasten the hutch or rear panel.
- Finish. Sanding, sealer coat, and final finish such as lacquer or oil.
Dowels give a clean look but need a drilling jig. Confirmat screws with glue are fast and strong for panel furniture. For heavy duty pieces use mortise and tenon or tongue-and-groove details. Choose the method that matches tool access and expected loads.
👉 Quality checks. Confirm carcasses are square and have no twist. Check that front gaps are even around each face. Run drawers fully in and out to verify smooth travel under load. Load test the top and hutch fixings for expected static weight.
Worked example
Example desk: W = 59 in, D = 31.5 in, T = 1 in. Right module width Wr = 13.8 in, module height Hb = 29.1 in.
- Tabletop area: A = 59 × 31.5 = 1858.5 in² ≈ 12.9 ft².
- Top volume: V = 1858.5 × 1 = 1858.5 in³ ≈ 1.08 ft³.
- Assuming average hardwood density ρ ≈ 44 lb/ft³, estimated top weight m ≈ 1.08 × 44 ≈ 47.5 lb.
- Approximate single cabinet box volume: V_box = 13.8 × 26.8 × 29.1 ≈ 10760 in³ ≈ 6.2 ft³.
Extra practical tips
Ergonomics first. Keep the desktop depth and knee clearance in mind. For a seated workstation target a tabletop height of about 720 to 760 mm depending on chair and work style. Leave at least 600 mm knee depth and 150 mm toe clearance under the front apron.
Cable management. Design a dedicated grommet and an internal channel behind the drawer bank. Add a removable panel under the top for power strips. Routing early saves headaches later.
Edge banding and finishing. If you use veneered panels, specify banding for visible edges. For solid tops, route an eased radius on exposed edges to reduce wear and make the surface comfortable to the touch.
Panel nesting and waste reduction. When generating cutting lists, consider nesting multiple parts on standard sheet sizes to minimize waste. Include a small kerf allowance per cut and plan the grain direction for consistent appearance.
Sustainability. Consider certified timber or durable plywood to increase lifespan. Thinner panels reduce material but may increase long-term repair and reinforcement needs.
Export and handoff. The tool can output PNG and a simple CSV cutting list. For CNC-ready work, export parts to a CSV with part names, lengths, widths, thickness and material type, then import into your nesting software.
Final checklist before you cut
- Verify all dimensions on the drawing against the intended room and hardware sizes.
- Confirm material thickness and adjust joinery clearances accordingly.
- Check drawer hardware spacing and edge band allowances.
- Print the cutting spec, mark the panels and cross-check twice before the first cut.
