Common mistake

Misunderstanding OS Map Scales

Students often confuse the scale of OS maps, thinking that a 1:50,000 scale means the map is larger than a 1:25,000 scale.

Remember that a smaller denominator in the scale (like 1:25,000) means a larger area is represented in the same space, making it more detailed than a 1:50,000 scale.
