You’ve found 5e Jump Calculator, a tiny online tool designed to tackle a surprisingly fiddly D&D 5e rule: figuring out jumps.
If you’ve ever halted the action to dig through the PHB, debated how far a character can really leap, or tried to remember which stats affect jump distance, this tool was built with you in mind.
What Is 5e Jump Calculator?
5e Jump Calculator is a no-frills calculator that automates the D&D 5e jump math so you don’t have to.
You plug in your character’s stats—including Strength, height, and situational modifiers—and the calculator instantly shows your:
Maximum long jump distance
Maximum high jump
Maximum reach during a jump
Key distances based on the 5e rules as written
No page-flipping, no rough estimates—just straightforward outputs you can rely on.
Why I Built This Tool
This site was born from actual game-night problems.
As a Dungeon Master and player, I often hit the same situation:
A player asks, "Can I make that jump?" and the entire table stalls while we check the rules.
The 5e rules for jumping are straightforward, just not when you’re under time pressure. I found myself reaching for the PHB over and over again, so I did what many nerdy DMs do: I made a dedicated tool.
5e Jump Calculator started as a personal helper, and then I cleaned it up and put it online in case other tables were just as tired of flipping pages mid-session.
Under the Hood (Without the Jargon)
This tool uses the official Dungeons & Dragons 5th Edition jumping rules as laid out in the core rules. In simple terms, it:
Uses your Strength score to determine base jump distances
Accounts for running vs standing jumps
Factors in your height and reach where appropriate
Respects the rules as written, without adding homebrew assumptions
You never have to think about the math directly. The calculator does the work and gives you the final, table-ready numbers.
Using This Tool During Play
5e Jump Calculator is meant to be:
Simple enough to use during combat
Accessible for beginners
Reliable for tables that like to follow RAW
You can use it to:
Check whether a character can clear an obstacle before they commit
Design encounters with realistic jumps in mind
Keep cinematic moments moving without arguing over distances
Just enter the stats and read the output. It’s meant to support your game quietly, not slow you down with options.
What’s Next?
Right now, 5e Jump Calculator is deliberately simple: it solves the jump problem and stops there.
In the future, I may:
Add more 5e movement-related tools
Cover more special abilities and conditions
Improve the layout and usability based on feedback
If you spot something off, or if you want to request a feature, to reach out. This site is built to help real tables, and your input directly guides future changes.
Thanks for stopping by. Here’s hoping it keeps your sessions moving and your jumps heroic.
