Solution
The scale of the current map window can be displayed in an info area at the bottom left corner of the
MapInfo window:
If this is displaying co-ordinates or a zoom width, right-click on the info area and choose Map Scale:
By default MapInfo presents the Map Scale as above (e.g. 1cm = 0.25km). To change this to a
cartographic scale (e.g. 1: 25000), open the Options>Preferences menu option, and select the Map
Window button. In the following dialog, enable the 'Use Cartographic Scale' option.
