Before ordering composite cladding, you need to know the standard WPC wall panel sizes — because width, thickness and length determine both the visual rhythm of your facade and the total material cost. This guide covers the complete dimensional specifications of WPC wall panels, fluted panels, great-wall panels and co-extrusion cladding, plus custom size options.
Standard WPC Wall Panel Dimensions
Most Chinese factories, including Ecowpc Board, produce WPC wall panels within the following standard range:
| Dimension | Common range | Most popular |
|---|---|---|
| Panel width | 140 – 219 mm | 150, 156, 160, 180, 219 mm |
| Panel thickness | 8 – 31 mm | 17, 20, 22, 24, 26 mm |
| Length | 2.2 – 5.8 m (customizable) | 2.9 m / 3 m / 5 m |
| Profile style | Fluted, great-wall (wavy), square, solid, hollow | Fluted 150×17 / 160×24 |
WPC Wall Panel Width & Thickness Explained
Narrow panels (140 – 160 mm)
Classic fluted profiles such as 150×17mm and 160×24mm create a fine, elegant vertical rhythm — ideal for villa facades and interior feature walls. More linear meters are needed per m², but the visual detail is premium.
Wide panels (180 – 219 mm)
Wide profiles like 219×26mm install faster (fewer pieces per m²) and give a modern, clean look. Widely used for commercial facades, hotels and large-scale cladding projects.
Thickness and performance
- 8 – 16 mm: lightweight interior panels, ceiling applications.
- 17 – 24 mm: the sweet spot for exterior wall cladding — strong, stable, easy to install.
- 25 – 31 mm: heavy-duty profiles for high wind load areas and structural walls.
Fluted, Great-Wall and Co-Extrusion Profiles
Profile geometry matters as much as size:
- Fluted (grooved) panels — parallel grooves create 3D shadow lines; the most popular style for both interior feature walls and exterior facades. See our fluted WPC wall panel guide.
- Great-wall (wavy) panels — rounded waves, softer light and shadow; popular for ceilings and feature walls.
- Solid vs. hollow — solid panels are heavier, stronger and better for load-bearing areas; hollow panels are lighter, cheaper and provide better thermal insulation.
- Co-extrusion panels — a protective cap layer over the core; recommended for exterior use. Explore co-extrusion WPC cladding.
Custom WPC Panel Sizes
All reputable manufacturers offer custom sizing. At Ecowpc Board, custom options include:
- Custom width (e.g. 100mm, 200mm, 250mm) with new mold development
- Custom length up to 5.8m per your building module
- Custom colors (10+ stock colors, or match a Pantone / wood sample)
- Custom surface textures: brushed, 3D embossed, wood-grain transfer, stone-effect
Custom molds typically require a development fee, but many standard profiles are available immediately.
How Many WPC Panels Do You Need Per m²?
Quick calculation: for a 150mm-wide panel with a 20mm installation gap allowance, you need roughly 6.7 linear meters per square meter of wall. For a 219mm panel, about 4.6 linear meters per m². Always add 5–8% waste for cutting and corners.
Frequently Asked Questions
What is the most popular WPC wall panel size?
The most popular exterior sizes are 150×17mm, 160×24mm and 219×26mm. For interiors, 140×10mm to 180×15mm profiles are common.
Can WPC wall panels be cut to custom length?
Yes — panels can be cut on site with a standard circular saw, or pre-cut at the factory to your exact lengths.
What is the maximum WPC panel length?
Most factories produce up to 5.8m. Longer panels reduce joints but require careful handling and flat storage.
Does panel width affect price?
Wider panels use more material per meter but require fewer pieces per m², so the cost per square meter of wall area is often similar. Custom widths may add mold development costs.
