Six-figure grid references
Six-figure grid references are used to locate objects or places within a grid
square and so are much more accurate than four-figure grid references. In order
to use six-figure grid references, you need to use the numbers on the grid lines
plus an estimate of where an object is located within the grid square.

In this example, the tree
symbol is located at 344286.
Let’s see how that works in a

The first task is to give the four-figure
grid reference of the square. This is:
29
34 4 28 5
Now imagine the bottom and side of
the grid square divided into tenths.
The tree is located 4 tenths of the way
along the bottom of the square.
So we add a 4 to our grid reference.
5
The tree is located 5 tenths of the
way up the side of the square.
So we add a 5 to our grid reference.
