In order to pinpoint an exact spot on a map, you’ll need to know how to give a grid reference. Most large scale maps have numbers that run around the border, from left to right, and top to bottom.

Four-figure grid references are found as follows: First, write the eastings number of the bottom left corner of the square (eastings are found along the bottom of the map).

Six-figure grid references are found as follows: Write the four figure eastings number, but then add a third number to show how many tenths of the way across the grid square the place or object lies.
