5e Jump Calculator
You’ve found 5e Jump Calculator, a small online tool designed to tackle a surprisingly fiddly D&D 5e rule: figuring out jumps.
If you’ve ever been the player who stopped a session to dig through the PHB, debated how far a character can really leap, or tried to remember exactly how the jumping math works, this site is for you.
What Is 5e Jump Calculator?
5e Jump Calculator is a free web tool that turns the official 5th Edition jumping rules into instant numbers.
You enter a few details about your character—including Strength, height, and situational modifiers—and the calculator instantly shows your:
Maximum long jump distance
Maximum high jump
Effective reach while jumping
Key distances based on the 5e rules as written
No guesswork, no mid-session rule dives—just straightforward outputs you can rely on.
Why I Built This Tool
This site was inspired by actual game-night problems.
As a Dungeon Master and player, I kept noticing the same situation:
A character wants to do something cool and cinematic with a jump, everyone stops to argue about the math.
The 5e rules for jumping aren’t especially complicated, but they are easy to forget. 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 turned it into a site so others could use it in case other tables were running into the same slowdown.
How It Works (In Plain Language)
This tool follows the official Dungeons & Dragons 5th Edition jumping rules as laid out in the core rules.
