Thanks for visiting 5e Jump Calculator, a tiny online tool created to fix a common D&D 5e table slowdown: jumping.
If you’ve ever been the DM who stopped a session to dig through the PHB, argued over if that chasm is actually jumpable, or tried to reconstruct from memory exactly how the jumping math works, you’re in the right place.
What Is 5e Jump Calculator?
5e Jump Calculator is a no-frills calculator that turns the official 5th Edition jumping rules into instant numbers.
You plug in your character’s stats—like Strength score, height, and a few relevant conditions—and the calculator immediately calculates your:
Long jump distance
High jump height
Maximum reach during a jump
Key distances based on the 5e rules as written
No page-flipping, no rough estimates—just clean numbers you can rely on.
Why This Calculator Exists
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 took the obvious next step: I wrote a little web app.
5e Jump Calculator began as something I used just for my home games, and then I cleaned it up and put it online in case other tables were running into the same problem.
Under the Hood (Without the Jargon)
This tool follows the official Dungeons & Dragons 5th Edition jumping rules found in the Player’s Handbook. In simple terms, it:
Uses your Strength to set how far and how high you can jump
Accounts for vs standing jumps
Factors in your height and reach where appropriate
Respects the rules as written, without adding homebrew assumptions
You don’t need to know the exact formula. The calculator handles it and shows you the result that matters at the table.
Making the Most of the Calculator
5e Jump Calculator is meant to be:
Fast enough to use mid-session
Clear enough for new players
Accurate enough for rules lawyers
You can use it to:
Check whether a character can clear an obstacle before they commit
Plan interesting movement options during encounter prep
Keep cinematic moments moving without arguing over distances
Just enter the stats and read the output. It’s meant to fade into the background, not become the focus of the session.
Future Plans
Right now, 5e Jump Calculator is kept lean on purpose: it solves the jump problem and stops there.
In the future, I may:
Add more 5e movement-related tools
Support more edge cases and optional rules
Polish the interface and add small quality-of-life features
If you find a bug, or if you have a suggestion, feel free to reach out. This site is for DMs and players like you, and your input directly guides future changes.
Thanks for using 5e Jump Calculator. May it help your party jump a little farther and your rules debates be a little shorter.
