Just how far is it to the pub? Three-quarters of UK adults are in danger of never finding out, according to a poll commissioned by Ordnance Survey to mark National Map Reading Week (11-17 July). It found that 77% of respondents couldn’t recognise the most basic OS map symbols, such as viewpoints and pubs. (The latter is marked with a classic pint “jug” glass with handle, so could the ignorance be down to the switch to straight beer glasses?)

But despite the popularity of walking – and the huge boost it saw during and after lockdowns – it seems most of us are still woefully bad at using a map to guide us.

Of the 2,000 adults surveyed, more than half (56%) admitted they’d got lost because they couldn’t use a map or follow a phone app correctly, with 39% resorting to calling friends and family, 26% flagging down help, and 10% calling mountain rescue to get home.

Even when they’re not actually getting lost, 31% said they were worried they might. Many adults (46%) said they were happier walking with someone else.

OS GetOutside ambassador Julia Bradbury said knowing a few basics about how to read maps, understanding symbols, contour lines and grid references can transform how you feel about getting outside.

“On the face of it these results seem to show the British public have a lack of confidence regarding their map-reading skills. It’s a shame, but can be quickly rectified.

“Map-reading skills give self-assurance and ease the fear of getting lost. That knowledge can unlock the outdoors and lead to wonderful adventures and discoveries.”

OS’s managing director for leisure Nick Giles said one of the key reasons they run National Map Reading Week (launched in 2016) is to make the outdoors “fun, accessible and safe.”

“We want to encourage people to better understand how good map skills, paper and digital, can inspire people to safely discover new places and adventures.

“We have a fantastic set of map-reading resources on our GetOutside website, so take some time to watch our videos or read the blogs,” Giles said.

OS’s tips for map reading

Choose the right map
The orange OS Explorer maps are 1 to 25,000 in scale, so every four centimetres on the map is a kilometre on the ground in real life. These are good for walking, running, kayaking and cycling. The pink OS Landranger maps are 1 to 50,000 in scale, so a kilometre for every two centimetres on the map, and suited for national trails such as Offa’s Dyke Path or the South Downs Way.

Understand map symbols
A key to what the map symbols mean is printed on every OS Explorer and Landranger map.

Understand contour lines
The faint reddish brown lines have a number that shows height above sea level. On a shallow slope the contour lines will be far apart, but if a slope is much steeper the lines are closer together.
