Unlike movement, jumping is determined by
a character’s Strength, not Speed (or Agility if
they have a specific talent). A character can jump
three times their relevant statistic across or high.
A treacherous jump—or one covering a greater
distance than that which a character can clear
automatically—requires an Athletics skill test. If
a character jumps onto difficult terrain, they must
take an Athletics (Agility) skill test to successfully
make the landing or else end up prone.
It just says three times their relative statistics, but not what the final value is in terms of a distance. Feet? Inches? Meters? Yards? If it's meters, someone jumping 12 meters is uncanny!
