Not sure of the correct dimesions but I'm sure they are taller atleast Plus Lanarkshire now add easy bed to the crates 4 bean tins is enough to cover the cardboard once this was done the doos were spot on when they returned, also another point we have the full length drinker and there is plenty of room for the pigeons to see and put there heads through as the spars run top to bottom of the crate Hope this helps pal
