How to set a grid reference

For those who missed out on the Brownies, the starts of all our walks always give a map or grid reference for greater accuracy. Every Ordnance Survey map of whatever scale is divided into 1km squares (The National Grid, not to be confused with power lines, which are something entirely different).
Map refs are often called Eastings and Northings:

  1. Looking at the blue grid lines in which your point lies, find the vertical grid line to the left. Look at the border at the top or bottom of the map and write down the two figure number. Estimate the distance from this line in tenths right (EAST) to your point.
  2. Now look at the bottom horizontal line of your grid square and read off the figure to the left or right. Estimate the distance up (NORTH) to your point.
  3. If you want to be really precise then add the figures identifying 100,000 metre squares in which the point lies. This is usually ST but walks further afield, say Dorset, may be SY. (Boundary is south of Beaminster: look for 00 on edge of map).
  4. To be extremely precise you can go to websites such as which gives lat/long, postcodes and much else.

So having digested all that for an example for Goathurst Church near Fyne Court on the Quantocks see below.

The map reference is therefore ST 256344
