The PHB says that a jump is based on strength. The high jump explains it well where if you’re standing then it’s 3ft + str modifier. However, a long jump says you cover a number of feet up to your str score.

So if a character has a -1 str modifier and a score of 8 in str then I would assume the following?

• high jump = 2 ft (3-1)
• long jump = 8 ft if running at least 10 ft first, 4ft if trying to jump from a standing position

Is my interpretation correct?
