Our black and white exhibit boards meet National History Day requirements. Our double-wall corrugated boards are 72 inches wide and 48 inches tall, there are two 23.5-inch-wide side panels and a 25-inch-wide center panel. We also offer an additional title panel that sits across the top of the exhibit board and is 40 inches wide and 10 inches tall. These display board dimensions are a significant reason our boards stand apart from ones you find at the craft or office supply store. Shop black or white presentation board and title headers today!
