If the card is printed in paper form, then it must specify a scale ratio of distance on the map to real distance on the ground. Figures of 1:10,000 means that 1cm on the map corresponds to 100 metres in reality. The lower the number specified after the unity, the larger the scale the more detailed is your map. On maps of scale 1:25000 and larger, you can even see trails.
