How to use the Map Scale Distance Calculator
Measure a map printed or displayed at the stated scale. Resizing a map changes the effective scale unless the measurement is tied to a correctly resized scale bar.
The calculation
Worked example
Four centimeters at 1:25,000 represents 1,000 m, or one kilometer.
Assumptions and limits
Represents planar map distance, not terrain-following route length. Projection distortion, elevation changes and travel conditions are excluded.
