### How do you calculate distance on a grid map?

A quick way to measure distance is to count each square you cross on the map. On your Ordnance survey map each grid square measures one kilometre from side to side and from top to bottom. If you go diagonally across a square, the distance will be a bit longer – about 1.5 km.

#### How do you calculate distance from a grid reference?

The distance calculation is simple pythagoras trigonometry, √(x² + y²) – the involved part is transforming OS grid references into regular co-ordinates in order to apply the maths (see the OS National Grid site for an explanation of the grid references).

If you’re using CalcMaps, click on Draw a circle and add the circle on the map area you’re interested in. Use can then use the drop-down menu to select the radius type you want to use. The tool automatically calculates the circle area as well.
