What sizes do commercial whiteboards come in?

Whiteboards are available from small 17"×23" desktop models to large 4'×16'+ wall-length boards. Common commercial sizes: 2'×3', 3'×4', 4'×6', 4'×8', and 4'×12'. For conference rooms, a 4'×6' or 4'×8' board is standard for groups of 6–12. For training rooms, a 4'×12' continuous board or multiple boards side-by-side provides maximum writing space. Custom sizes are available from some manufacturers. At OfficeFurniture2go.com, we stock the most common commercial sizes — call 1-800-460-0858 for size guidance based on room dimensions.
