If you calibrate your screen resolution, the application will:
If you don’t need these features, just click the Cancel button.
To calculate map scale, the application needs to know your screen resolution (pixels per inch).
To set pixels per inch, make the black line segment exactly one inch long:
When you change your screen resolution, the application resets the calibration to “(not to scale)”, but it remembers the previous value of pixels per inch until you explicitly change it, because it will still be valid if you return to the previous screen resolution.
