2. Put a line on whatever object in the image that you know the height/length of (ex. human height, you put the two end points at the head and feet)
3. Put a line on top of the previous line, but this time, measured to the known height/length (ex. human height, you put the bottom endpoint at the feet, but the top is X units where X is the actual height)
4. Use the 'scale' command (shortcut: SC), enter, highlight the image and the first line, enter, select the bottom point (or wherever the two lines' end points converge), reference option (shortcut: R), enter, select the converging points again (e.g. feet of the human in the image) and then the other end of the first line, and then the other end of the second line.
