The signpost seems taller? Is it? Why?

Yes! OSI’s posts generally stand 6’ – 6’ 6” above ground. This is almost a foot taller than the others in the Chicagoland area. This is significant because it presents the sign panel at the optimal viewing height…eye level (this technique is also used with the DOT signs). Generally speaking, the center of the sign hung from our posts is approximately 5’ above ground. This makes it much easier for potential buyers to see the sign and information while driving by the property.
