Welcome to the official D&D 5e Jump Calculator. This tool accurately determines your character’s maximum Long Jump distance and High Jump height based on their Strength score and whether they take a running start (10 feet of movement).
D&D 5e Jump Calculator
D&D 5e Jump Formula:
Strength Modifier (M): $\lfloor (S – 10) / 2 \rfloor$
Long Jump (L, in feet):
If Running Start: $L = S$
If Standing Jump: $L = \text{ceil}(S / 2)$
High Jump (H, in feet):
If Running Start: $H = 3 + M$
If Standing Jump: $H = \text{ceil}((3 + M) / 2)$
Note: All jump distances/heights use up movement speed.
Formula Source: D&D 5e Basic Rules (Wizards of the Coast/D&D Beyond)
Variables:
- Strength Score (S): The character’s raw Strength attribute (typically 1-30). This is the core variable for determining maximum jump distance.
- Running Start: A boolean condition (Yes/No) that determines whether the character moved at least 10 feet immediately before the jump. This significantly increases both Long and High Jump distance.
- Movement Speed: The total distance a character can move in a turn. Although not used in the max distance *formula*, the jump distance/height is deducted from this speed.

What is D&D 5e Jumping?
Jumping in Dungeons & Dragons 5th Edition is treated as part of a character’s movement. It does not require an action, but the distance covered is subtracted from the character’s movement speed for that turn. This allows characters to traverse gaps, leap over obstacles, and reach elevated positions dynamically during combat or exploration.
The primary limiting factor for a character’s jump capability is their Strength score. Unlike many previous editions, the rules simplify the calculation to make them fast and intuitive at the table, ensuring that high Strength characters are significantly better at jumping than those with low Strength.
How to Calculate Jump Distance (Example):
- Input Variables: Assume a Fighter has a Strength Score of 16 and takes a Running Start.
- Determine Strength Modifier: $M = \lfloor (16 – 10) / 2 \rfloor = 3$.
- Calculate Long Jump: Since the Fighter has a Running Start, the Long Jump distance is equal to their Strength score. $L = 16$ feet.
- Calculate High Jump: Since the Fighter has a Running Start, the High Jump height is $3 + M$. $H = 3 + 3 = 6$ feet.
- Calculate Standing Jump (If no run-up): If the same Fighter stood still, the Long Jump would be $\text{ceil}(16 / 2) = 8$ feet, and the High Jump would be $\text{ceil}(6 / 2) = 3$ feet.
Frequently Asked Questions (FAQ):
Can I jump further than my Movement Speed?
No. The distance or height of your jump, regardless of your Strength score, is limited by the remaining movement you have left on that turn.
What is the minimum running start required?
To gain the benefit of a running jump, you must move at least 10 feet on foot immediately before the jump. If you don’t move 10 feet, the jump is considered a standing jump, and the distance is halved.
Does a High Jump require a check?
No check is required to reach the maximum height (3 + Str Modifier). However, if you need to clear an obstacle taller than that, you must succeed on a DC 10 Strength (Athletics) check to clear the obstacle, and your jump height is still limited by your movement.
Is the D&D 5e jump calculator official?
This calculator is based on the official rules published in the Dungeons & Dragons 5th Edition Player’s Handbook and Basic Rules. It correctly applies the formulas for maximum Long Jump and High Jump distances.
