Use this browser tool to plan wall and ceiling cladding with tongue and groove wood panels. The calculator helps you choose board sizes, estimate the number of boards needed, compute total volume and mass, and get a cost estimate while accounting for wood moisture. An interactive three dimensional preview with realistic textures shows how the covering will look on your walls and ceiling. The tool runs in the browser, needs no installation, and is optimized for phone screens.

How to use
- Select board orientation, vertical or horizontal.
- Enter room dimensions, length, width and height in metres.
- Specify board parameters, width, length and thickness in millimetres.
- Choose coverage option for walls, ceiling or both surfaces.
- Click calculate to receive board count, total volume, mass and a cost estimate.
- Inspect the interactive 3D model of the room with applied panel textures and rotate the camera to review the layout.
Calculation formulas
Volume of a single board given thickness t in millimetres, width w in millimetres and length L in millimetres:
$$V_{board} = \frac{t \times w \times L}{10^{9}} \quad \text{cubic metres}$$
Total material volume for N boards:
$$V_{total} = V_{board} \times N$$
Mass including moisture content W expressed in percent:
$$m = V_{total} \times \rho \times \left(1 + \frac{W}{100}\right)$$
where rho is the dry wood density in kilograms per cubic metre.
Worked example
Consider a room 4.0 by 3.0 by 2.5 metres. Boards are 100 millimetres wide, 3000 millimetres long and 12 millimetres thick. Assume 12 percent moisture and dry wood density of 500 kilograms per cubic metre. Use N equals 100 boards as a sample quantity.
- Volume of one board V board equals 12 times 100 times 3000 divided by 1e9, that is 0.0036 cubic metres.
- Total volume V total equals 0.0036 times 100, that is 0.36 cubic metres.
- Mass m equals 0.36 times 500 times 1.12, that is 201.6 kilograms.

Standard board sizes
| Parameter | Common sizes, mm | Notes |
|---|---|---|
| Thickness | 12, 14, 16, 18, 20 | Influences stiffness and final weight |
| Width | 80, 90, 100, 110, 120, 130 | Chosen by design and species |
| Length | 2000, 2500, 3000, 4000, 6000 | Select by project and ease of handling |
| Profile | Shiplap, euro, blockhouse | Face shape affects look and overlap |
| Tongue and groove | Standard and wide | Join type for tight and stable seams |
Shrinkage and allowable dimensional change
| Indicator | Typical value | Comment |
|---|---|---|
| Thickness shrinkage | 3–6% | Depends on moisture change and species |
| Width shrinkage | 6–12% | Most visible when humidity varies |
| Length shrinkage | 0.1–0.3% | Usually negligible |
| Recommended installation moisture | 8–12% | Optimal to avoid post installation warping |
| Maximum storage moisture | 18–20% | Higher values may cause rot and deformation |
Practical recommendations
- Always allow panels to acclimatize in the room for at least two to three days before installation.
- Use species with higher moisture resistance in damp rooms.
- Keep board thickness consistent across an installation to ensure a uniform finish and predictable fastening.
- When assembling multi board layouts, plan joints and end cuts to minimize visible seams and waste.
- Add a safety margin of three to five percent to material estimates for cutting loss and minor defects.
🛠 The calculator renders a scaled three dimensional room and maps panel textures according to orientation. For very large coverings the tool switches to an optimized tiling texture to preserve performance. Camera controls allow rotation and close inspection of seams and edge conditions.
Results are intended for planning and budgeting. For final estimates and material orders generate a cutting layout and confirm exact board lengths and waste factors. If precise mass or structural values are required measure sample boards or consult supplier data for the exact density of the batch.
