In Dungeons & Dragons 5th Edition (D&D 5e), physical ability scores play a vital role in determining what your character can achieve. Whether you’re leaping over a chasm, jumping across rooftops, or making a dramatic escape, your jump distance is determined by one key factor—Strength.
That’s where our Jump Distance 5e Calculator comes in. This free, user-friendly online tool allows you to instantly determine how far and how high your D&D character can jump based on their Strength score and whether they have a running start. It’s an essential companion for players and Dungeon Masters who want quick, accurate results during gameplay—no math required.
Jump Distance 5e Calculator
What Is the Jump Distance 5e Calculator?
The Jump Distance 5e Calculator is a simple online tool designed to automatically compute both Long Jump and High Jump distances for characters in Dungeons & Dragons 5th Edition.
In D&D 5e, jumps are governed by your Strength score and whether or not you have at least a 10-foot running start. While it’s possible to do the math manually, it can slow down the flow of your adventure. This calculator simplifies that process, helping you focus more on storytelling and strategy.
With just two quick inputs—your Strength score and whether you have a running start—the calculator instantly displays both:
- Long Jump Distance (in feet)
- High Jump Distance (in feet)
How to Use the Jump Distance 5e Calculator
Using the Jump Distance 5e Calculator is straightforward and takes just a few seconds:
- Enter Your Strength Score:
Input your character’s Strength score (between 1 and 30) into the provided field. - Select If You Have a Running Start:
Choose Yes if your character moved at least 10 feet before jumping. Choose No if the jump is made from a standing position. - Click “Calculate”:
The calculator instantly displays two values:- Long Jump Distance – how far your character can jump horizontally.
- High Jump Distance – how high your character can jump vertically.
- Use “Reset” to Start Again:

That’s it—fast, accurate, and perfect for mid-session decisions.
Example: How Jump Distance Works in D&D 5e
Let’s see how the calculator works with a few examples:
Example 1 – Running Long Jump
- Strength Score: 16
- Running Start: Yes
According to D&D 5e rules, your long jump distance equals your Strength score in feet.
So, with a Strength of 16 and a running start, your character can jump 16 feet.
Your high jump distance equals 3 + your Strength modifier (rounded down).
A Strength of 16 gives a modifier of +3, so:
3 + 3 = 6 feet high
The calculator will display:
- Long Jump Distance: 16 ft
- High Jump Distance: 6 ft
Example 2 – Standing Jump
- Strength Score: 16
- Running Start: No
Standing jumps cover only half the distance of a running jump.
The calculator automatically adjusts:
- Long Jump Distance: 8 ft
- High Jump Distance: 3 ft
This quick calculation saves time and ensures accuracy during intense gameplay moments.
Why Use a Jump Distance Calculator?
Manually calculating jumps can slow down your D&D sessions, especially when multiple characters are involved. Using a tool like this offers several advantages:
- ✅ Instant Results: No need to pause the game to look up formulas.
- ✅ Error-Free Calculations: The tool applies all official D&D 5e jump rules.
- ✅ Supports All Characters: Works for Strength scores from 1 to 30.
- ✅ Improves Gameplay Flow: Keeps the session moving smoothly.
- ✅ DM-Friendly: Dungeon Masters can use it to quickly determine NPC jump ranges.
For players and Dungeon Masters alike, this calculator is a handy addition to your D&D toolkit.
Understanding Jump Mechanics in D&D 5e
To make the most of this calculator, it helps to understand the rules behind it:
1. Long Jump (Player’s Handbook, p. 182)
When you make a long jump, you cover a number of feet equal to your Strength score, provided you move at least 10 feet on foot before the jump.
If you make a standing long jump, you can leap only half that distance.
2. High Jump
When you make a high jump, you leap into the air a number of feet equal to 3 + your Strength modifier, if you have a 10-foot running start.
If you jump from standing still, the height you can reach is half that total.
The calculator uses these exact formulas to deliver accurate distances for both jump types.

Best Practices for Using the Tool
To get the most accurate results:
- Always double-check your character’s Strength score on their character sheet.
- Remember that some spells, items, or effects (like Jump or Boots of Striding and Springing) may triple or boost jump distances—apply those effects manually after calculating.
- Use Yes for “Running Start” only if your character actually moved at least 10 feet before jumping.
