It measures 40 in. wide by 51 in. high. It is for children 3 and up and comes in a great carrier bag made from the same material as the castle. Over all it seems to be well built. It is made of nylon and only requires the assembly of 4 thin plastic poles on the inside. It's has mesh windows for ventilation and a front door that you can roll up and tie in place.
A couple of things I was not impressed with however, was one of the pieces of Velcro that holds the inside poles in place was missing, the picture on the carrying case shows 2 ties for the door and it only has one. The instructions are drawn pictures that aren't very clear showing how to fold it back up to put it in the carrier bag. I still have not been able to fit mine in the bag.
I think it is a very cute tent and kids would love it but some of the problems need to worked out. it does sell for a very good price.
