5e Jump Calculator

You’ve found 5e Jump Calculator, a straightforward online tool designed to tackle a surprisingly fiddly D&D 5e rule: figuring out jumps.


If you’ve ever paused combat to look up the exact jumping rules, debated whether a running start is enough, or tried to remember exactly how the jumping math works, you’re in the right place.





What Is 5e Jump Calculator?

5e Jump Calculator is a free web tool that automates the D&D 5e jump math so you don’t have to.


You provide basic character info—like Strength score, height, and a few relevant conditions—and the calculator instantly shows your:





Maximum long jump distance


High jump height


Effective reach while jumping


Key distances based on the 5e rules as written



No page-flipping, no rough estimates—just clear results you can rely on.





Why I Built This Tool

This site was inspired by real table frustration.


As a Dungeon Master and player, I kept running into the same situation:




A player asks, "Can I make that jump?" and everyone stops to argue about the math.




The 5e rules for jumping are simple on paper but annoying in the moment. I found myself reaching for the PHB over and over again, so I took the obvious next step: I made a dedicated tool.


5e Jump Calculator was originally just a quick private tool, and then I decided to share it in case other tables were running into the same slowdown.





How It Works (In Plain Language)

This tool implements the official Dungeons & Dragons 5th Edition jumping rules as laid out in the core rules.
