I have built the 1/35 dora and I have found it to be 7'-1'' long X 1'-2'' wide X 2' high. This is a great model to build but plan on some place to put it before you start. I also made a base for it and install the track so I had a place to put the sub assembles, this was important do to the many differant rail cars for the gun itself. Good luck, it will take a some time to build ,but enjoy.
