Buying Guide
What size should you choose?
Standard poster sizes like 12″ x 16.5″ are versatile for frames and displays. For larger signage, 24″ x 36″ boards offer expansive surfaces, while 8″ x 10″ or 11″ x 14″ boards are great for small projects or tabletop displays.
Why 3/16″ thickness?
The 3/16″ (about 5 mm) core provides a balance between rigidity and lightness. It resists sagging in displays and handles cutting without excessive tearing, making it suitable for both school and craft use.
Material and durability considerations
Most boards use a polystyrene foam core with paper layers. Acid-free cores help prevent yellowing of artwork over time. Look for smooth, paint-friendly surfaces that tolerate markers, glue, and light coatings without warping.
Cutting and finishing tips
Use a sharp craft knife or utility blade for clean cuts. A straight edge or cutting mat helps prevent ragged edges. For precise shapes, score first before full cuts to reduce edge tearing.
Packaging and delivery considerations
Choose products with protective packaging, especially for large sheets. Corner protectors and bubble wrap minimize corner damage during shipping, which is essential for boards stored flat and ready to use.
What to avoid
Avoid boards with brittle edges or surfaces that easily scratch or crumble when cut. For long-term displays, ensure the surface is suitable for your chosen media, whether markers, paints, or photos glued on.
