Canvas Board. 16×20.

Description

16x20 inch (approx. 40x50 cm) canvas board is a flat, rigid painting surface created by mounting primed cotton canvas onto a sturdy backing, such as MDF or high-quality paperboard. Unlike stretched canvases, these boards offer a firm, non-flexible foundation that is warp-resistant and easier to frame.
Key Specifications
Dimensions: The standard size is 16 x 20 inches (40.6 x 50.8 cm), providing a generous area for medium-to-large artworks.
Material: Most boards use 100% cotton fabric, often in a medium-grain texture that balances detail work with bold brushstrokes.
Backing: High-quality versions typically feature a 4mm thick MDF (Medium-Density Fiberboard) backing for superior stability and to prevent bending during use.
Priming: These boards come pre-primed with acid-free acrylic titanium gesso, making them ready for immediate use. Triple-primed options are available for even better paint adhesion.
Archival Quality: Many brands are acid-free and treated with antifungal agents to prevent yellowing or deterioration over time
