This item is described as "over 6 feet tall" in the product listing, specifically 72 inches.  The delivered trellis is closer to 56 inches tall, probably less once assembled.  At first, I thought I received the wrong item and completed an exchange, but was sent another short trellis.  
Even if it had been as tall as described in the listing, I'm not sure it would be sturdy enough to support the climbing rose it was intended for.  It's formed from lightweight tubing and probably not suitable for the weight of a rose vine.  It's probably fine for lighter weight vines that don't need more than 4 feet of support.
