Calculate the maximum jumping distance for your D&D 5th Edition character for both long jumps and high jumps, accounting for strength score and running starts.
D&D Jump Calculator
D&D Jump Calculator Formula:
STR Modifier: $\text{floor}((\text{STR Score} – 10) / 2)$
Long Jump: $\text{STR Score}$ (Running) or $\text{STR Score}/2$ (Standing)
High Jump: $(3 + \text{STR Mod})$ (Running) or $(3 + \text{STR Mod})/2$ (Standing)
Formula Source: D&D 5e Basic Rules (Movement) | Player’s Handbook Errata
Variables:
- Strength Score (STR): The primary attribute used for jumping distance. A character can jump a number of feet equal to their Strength score on a long jump, or $3 \text{ ft} + \text{STR Mod}$ on a high jump (with a running start).
- Movement Speed (SPD): The character’s speed (e.g., 30 ft). The distance jumped is subtracted from the character’s movement for the turn.
- Running Start: A long jump or high jump requires a 10-foot running start to achieve maximum distance. If you don’t move at least 10 feet immediately before the jump, the distance is halved.

What is D&D Jump Calculator?
The D&D Jump Calculator is a utility based on the ruleset of Dungeons & Dragons 5th Edition (5e) that determines the maximum horizontal and vertical distance a player character can travel with a single athletic effort. In 5e, jumping distance is tied directly to the character’s Strength score, reflecting their raw physical power.
Understanding your maximum jump distance is crucial for navigating combat and exploration. A successful jump can allow a character to clear chasms, jump over obstacles, or reach higher ledges without needing a skill check, as long as the distance is within the calculated maximum.
How to Calculate D&D Jump (Example):
- Determine Strength Score: Start with the character’s Strength score (e.g., 18).
- Calculate STR Modifier: The modifier is $\text{floor}((18 – 10) / 2) = +4$.
- Apply Running Start: Assume the character takes a Running Start (10 feet of movement before the jump).
- Calculate Long Jump: Long Jump distance is equal to the Strength Score, which is 18 feet. The character uses 18 feet of their movement speed (e.g., 30 ft) to clear the distance.
- Calculate High Jump: High Jump height is $3 \text{ ft} + \text{STR Mod}$, which is $3 \text{ ft} + 4 \text{ ft} = 7 \text{ feet}$. The character also uses 7 feet of their movement speed to cover the jump.
Frequently Asked Questions (FAQ):
Yes, but it requires a successful Strength (Athletics) check with a Difficulty Class (DC) set by the DM. The calculated value represents the maximum distance a character can clear automatically without a check.
Heavy armor can reduce your Movement Speed, which limits how far you can jump in a single turn. However, the maximum distance based on your Strength score itself remains unchanged.
A Strength (Athletics) check is only required if the jump exceeds the maximum distance based on your Strength score, or if there is a specific, hazardous condition (like a slippery surface).
The number of feet you jump vertically is subtracted from your movement speed, just like a long jump. Additionally, reaching up to grab a ledge requires a vertical reach of the jump height plus your height.
