There are a few reasons why the height/weight might be a little different. Their countries use the metric system, so the measurements might be rounded up or down. Also there may be a time difference between the time the profiles appear on one site or another. Their weight could change in that time, and also some offices have the girl get on a weight scale and measure her height when she joins and others just takes down what she says her weight and height are. So as you can see there can be all sorts of different reasons.
