[RPG] What happens when you run out of movement while jumping


According to the PHB (p 182) after a 10 foot movement the player is able to make a long jump whose length is equal to their strength score. Each foot jumped costs 1 foot of movement.

I have a character with a speed of 25 who can jump 30 (due to the jump spell tripling their normal jump distance of 10). What happens when he runs out of movement?

  1. The player moves the full distance of the jump
  2. The player stops moving when they run out of movement and fall
  3. The player moves up to their movement speed, then finishes the jump on their next turn

From the Movement and Position section on page 70 of the Player's Basic Rules:

On your turn, you can move a distance up to your speed. You can use as much or as little of your speed as you like on your turn, following the rules here. Your movement can include jumping, climbing, and swimming. These different modes of movement can be combined with walking, or they can constitute your entire move. However you’re moving, you deduct the distance of each part of your move from your speed until it is used up or until you are done moving.

Regardless of how you're moving, you can only move up to your speed.

From the section on jumping, page 64:

Long Jump. When you make a long jump, you cover a number of feet up to your Strength score if you move at least 10 feet on foot immediately before the jump.

So your player can't jump 30 feet if their speed is 25 feet. It's the same as them saying "I want to walk 30 feet with my move." Well, no, you can't. You only have 25 feet, so that's as far as you can move. You're not forced to jump as far as you can possibly jump, so your player should move 10 feet, then jump 15 feet.

A point of non-rules justification: Your jumping distance is constrained by your speed as well as your Strength. A wood elf monk can jump further than a halfling wizard even if they have the same Strength, and that makes sense, because the wood elf monk can run twice as fast. It simply wouldn't make sense for the halfling to be able to jump as far.

As a side note (or the most important part of the answer, depending on your point of view), Jeremy Crawford says the same thing - your jumping distance is constrained by your movement.
