There doesn't seem to be a consensus on that. Some go by the tip of the saddle, some use the center of the rails and others try to determine where the sitbones will be. None of them are all that good, unless you are using the same saddle on all of your bikes
For my own bikes with different saddles, I measure to where the saddle just reaches its widest point.
