Quoted from grantopia:
It would be about the same as Zach notes above. I would add that the Escalara itself is pretty heavy (he could probably give you an exact weight), but it will add some weight to the already heavy load of a game if you are trying to lift it and turn.
my landing is 37.5" measuring when you walk down the stairs and when you come up it is slightly longer at 40". When I use the escalera to bring a game up, it barely clears the wall when I make the turn on the landing. I am unable to use the escalera to get it down and instead slide the machine down on the carpeted stairs.
