Are you planning a hiking, camping, or biking trip? If so, make sure you know how to measure distance on a map. If you’re new to map reading, understanding all those symbols and curvy paths on a map can be a little daunting for you. It may look confusing and not being able to figure out which path is directed to which place can totally make or break your excursion. Don’t worry, reading a map is not as tough as it seems to be; it’s quite easy!

Choose the Right Map

There are many distinct types of map such as topographic maps, atlases, weather charts, etc. You’ve to check that the map you’re using is ideal for the trip you’re planning.

If you are planning a running, cycling, or walking trip, it is suggested to use a map with many details that does not show much more area than you want to explore. Opt for a road atlas with fewer markings, but giving more information of the road numbers and names etc.

Scale Identification

Identifying the scale on a map will let you know whether the map you’ve chosen is the right one or not. Scale tells you the link between a distance on the land and its graphic equivalent on a map. Here are different types of scales:

  • A Graphic Scale

Generally, the scale is written at the bottom of a map or in the information box called legend.

  • A Representative Fraction

If your map comes with a cover, check its front for the scale in the ratio format. In some maps, it is found next to the graphic scale. For example: if the scale is mentioned as 1:25 000, then it indicates that every 1cm on the map equals to 0.25km on the ground.

  • A Word Statement

A word statement is less common than representative fraction or graphic scale, but it is equally helpful and comparatively less complicated to understand the route.

Measuring Distance on a Map

Now that you know about different scales on a map, it’s time to measure the distance on a map. You can do so by using a ruler or a string.

  1. Using a Ruler

If the path you want to measure is straight, you’ve to take a ruler and note the distance from A to B in centimetres.

  1. Using a Piece of String

If the route is curvy with many changes in the direction, then take a piece of string. Carefully trace the route with the string and make the markings on it as you go, if required.

Calculating the Actual Distance of the Path

Once you know the distance in centimetres, you need to see your scale and convert it into kilometres or miles.

For instance: If the scale is 1:100 000 and the path measures 5cm on a map, then the route is 5km long.

As an option, you can lay a ruler or the string adjacent to the graphic scale to find out the actual distance.

Follow these steps to measure distance on a map on your next outdoor excursion.
