Map Rulers for Lat/Lon and UTM/MGRS/USNG

Stock Rulers for Common Map Scales

These rulers can be used to measure or plot latitude/longitude coordinates, UTM/MGRS coordinates, and to measure distances in either meters or miles. You will find them useful when you are working with a GPS receiver and paper maps.

Each ruler is designed for a specific scale map. You must use a ruler that matches the scale of your map.

On the front side, the rulers have minutes and seconds on one edge and decimal minutes on the other edge, allowing you to use either coordinate format. On the back side, the rulers have distance in meters on one edge, and distance in either miles or nautical miles on the other edge. Latitude is measured directly with the ruler. But, since a degree of longitude covers a shorter distance as you move towards the poles, the ruler is used on a diagonal to measure longitude.

For more information on using lat/lon coordinates and for specific instruction on using the MapTools rulers to measure lat/lon, visit the Lat/Lon Tutorial Pages.

The rulers are printed on a sturdy 20mil white plastic stock for durability.

Additional ruler specifications, and a guide to the maps they are designed to be used with are here.

MapTools provides rulers for measuring latitude/longitude and UTM/MGRS coordinates in many of the most common map scales. Rulers are available individually, or in sets.

We also have Map Ruler Sets specifically designed for the Benchmark Road & Recreation Atlas series and the DeLorme® Atlas & Gazetteer series

You can create a map ruler for any map scale you may encounter.

The four long edges of the ruler will have scales for measuring:

Latitude in Degrees, Minutes and Seconds, or Degrees and Decimal Minutes, or Decimal Degrees
Longitude for a specified latitude. No more need to use the latitude scale at an angle!
Miles statute or nautical, and divided into decimal or fractional subdivisions.
Kilometers
