Most brickwork is about 4 courses per foot in height, including the mortar between the bricks. So if you count the number of courses over, say 10ft height of a building (or measure the height of 40 courses), this will give you a check on the scale. I'm an 00 man myself, so I've only handled Skaledale and 4mm Metcalfe buildings, so I cannot comment on the apparent difference.
