The height of the character block for each letter is given in scaled feet or meters depending on the units setting of AGi32. The Text Size will default to either 1 (ft or m) or the last size used. When printing or plotting, text is scaled according to the output scale. For example: Text Size of 5 plotted at a scale of 1”=30' will be 1/6” tall (5/30).
Text size is specified using the current display units and rounded according to the precision setting in the System Settings dialog. However, in the graphics display area, the text size is rounded to the nearest pixel. Consequently, at various levels of Zoom, the text may appear to 'stretch' or 'shrink' relative to other drawing entities. Example: Text cannot be displayed 10.5 pixels high. The text size is rounded to the nearest pixel for display purposes. It must be displayed at 10 pixel (text shrinks) or 11 pixels (text stretches).
Generally, you will want to have an idea of the desired size of the text before entering a value in the cell for Text Size. Calculation values provide a good starting point for determining appropriate text sizes for Statistical Areas, schedules, and LPD/UWLR Areas.
