The scale for an
orienteering map is 1:15 000. Terrain that cannot be
fieldworked at a scale of 1:7500 and legibly presented at a scale of 1:15
000, is not suitable for international foot-orienteering.
Maps at 1:10
000 may be produced for relay and short distance (plus medium) competitions.
The scale
1:10 000 is recommended for older age groups (45 and above) where reading
fine lines and small symbols may cause problems or for younger age groups (age
classes 16 and below) where the capacity of reading complex maps is not fully
developed.
Where a map
is enlarged to a scale of 1:10 000 or greater, all lines and symbols must
be enlarged to 150% (like a blueprint).
