5e Jump Calculator
Calculate D&D 5th Edition jumping distances for long and high jumps based on Strength scores.
Long Jump Distance
10 ftFormula: Long jump equals Strength score. High jump equals 3 + Strength modifier. 1.5x height is added for vertical reach. Standing jumps are halved.

What is a 5e Jump Calculator?
A 5e jump calculator is an essential tool for players and Dungeon Masters in Dungeons & Dragons 5th Edition to quickly determine how far and how high a character can leap without requiring a complex check. In 5e, jumping is tied directly to your Strength score, making it one of the most reliable forms of movement-rules in the game.
Who should use it? Any player playing a martial class like a Barbarian or Fighter, or a DM looking to see if an NPC can cross a ravine. A common misconception is that jumping requires an Athletics check. In reality, the 5e jump calculator provides your "passive" jumping distance, which is a static number. Checks are only needed to clear obstacles or exceed these base limits.
5e Jump Calculator Formula and Mathematical Explanation
The math behind D&D jumping is divided into two main categories: Long Jumps and High Jumps. Here is the step-by-step derivation used in our 5e jump calculator.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| STR | Strength Score | Points | 1 – 30 |
| MOD | Strength Modifier | Bonus | -5 to +10 |
| H | Character Height | Feet | 3 – 8 |
Long Jump: If you move at least 10 feet on foot immediately before the jump, you cover a distance equal to your Strength score. If you make a standing long jump, you can leap only half that distance.
High Jump: With a 10-foot running start, you leap into the air a number of feet equal to 3 + your Strength modifier. Standing high jumps are halved. Additionally, you can reach 1.5 times your height above your head during the jump.
Practical Examples (Real-World Use Cases)
Example 1: The Goliath Fighter
A Goliath with a Strength of 20 and a height of 7 feet wants to clear a gap. Using the 5e jump calculator, with a running start, they leap 20 feet horizontally. Their high jump would be 3 + 5 (mod) = 8 feet. Their total vertical reach would be 8ft + (7ft * 1.5) = 18.5 feet.
Example 2: The Halfling Rogue
A Halfling with 10 Strength and 3 feet of height makes a standing long jump. The 5e jump calculator shows a distance of 5 feet (10 / 2). Their standing high jump is (3 + 0 mod) / 2 = 1.5 feet.
How to Use This 5e Jump Calculator
- Enter your Strength Score (found on your character sheet).
- Input your character's height in feet to calculate reach.
- Select whether you have a 10-foot running start.
- Choose any active multipliers like the Jump spell or Step of the Wind.
- Interpret the results: The primary box shows horizontal distance, while cards below show verticality.
Use these results to decide if your character can clear a pit without an dnd-tools athletics check or if you need to use a resource like a spell.
Key Factors That Affect 5e Jump Calculator Results
- Movement Speed: Every foot jumped counts against your movement for the turn. If you have a 30ft speed and jump 20ft after moving 15ft, you technically stop mid-air or can't complete the jump by RAW.
- Jump Spell: This triples your distance, allowing even low-strength characters to clear massive gaps using the 5e jump calculator.
- Boots of Striding and Springing: These triple your jump distance but limit it to your remaining movement.
- Remarkable Athlete (Champion Fighter): Adds your Strength modifier to your long jump distance.
- Step of the Wind (Monk): Doubling jump distance for a Ki point is a common interaction in strength-guide scenarios.
- Difficult Terrain: Landing in difficult terrain usually requires a DC 10 Acrobatics check to land on your feet.
Frequently Asked Questions (FAQ)
Q: Can I jump further than my movement speed?
A: No. In 5e, your jump distance is limited by your total movement speed for that turn.
Q: Does the 5e jump calculator account for Athletics checks?
A: No, the calculator shows the guaranteed distance. A DM might allow an combat-mechanics check to push beyond these limits.
Q: How do height and reach work?
A: Reach is your high jump height + 1.5 times your character's height, representing how high you can grasp a ledge.
Q: What happens if I have negative Strength modifier?
A: Your high jump is still at least 0 feet. You can't jump negative distances.
Q: Do these rules apply to mounts?
A: Yes, horses use their own Strength score in the 5e jump calculator.
Q: Does being Encumbered affect jumping?
A: Directly, no, but it reduces your movement speed, which may limit the total distance you can actually cover.
Q: Are standing jumps always half?
A: Yes, according to the Player's Handbook, standing jumps provide half the distance of a running jump.
Q: Can I jump as a bonus action?
A: Jumping is part of your movement, not an action, unless you are using a feature like a Cunning Action dash to gain more movement.
