Which font size is recommended for small scale maps?

For small scale maps, a font size of 3-point is recommended to ensure that text remains legible while fitting within the constraints of the map design. At small scales, where the area represented by the map is large and detail can become compressed, larger text may dominate the visual elements and make the map crowded or difficult to read. Conversely, smaller points can render the text almost unreadable, especially when printed or viewed at reduced sizes.

The 3-point font strikes a balance, allowing for the inclusion of necessary information without overwhelming the spatial features displayed. This size is generally accepted as the smallest acceptable size that can still be read under normal viewing conditions, especially when the map is printed or displayed in a format where detail is crucial, but space is limited.
