5e Jump Calculator
Welcome to 5e Jump Calculator, a small online tool designed to tackle a surprisingly fiddly D&D 5e rule: jumping.
If you’ve ever been the player who paused combat to look up the exact jumping rules, debated whether a running start is enough, or tried to reconstruct from memory which stats affect jump distance, this tool was built with you in mind.
What Is 5e Jump Calculator?
5e Jump Calculator is a simple online helper 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 spits out your:
Maximum long jump distance
High jump height
Maximum reach during a jump
Other useful jump-related numbers based on the official rules
No guesswork, no mid-session rule dives—just clear results you can rely on.
Why I Built This Tool
This site was born from repeated rules questions at the table.
As a Dungeon Master and player, I often hit the same situation:
A character wants to do something cool and cinematic with a jump, the entire table stalls while we check the rules.
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 took the obvious next step: I built a calculator.
5e Jump Calculator started as a personal helper, and then I decided to share it in case other tables were running into the same slowdown.
How the Calculator Handles the Rules
This tool implements the official Dungeons & Dragons 5th Edition jumping rules as written in the PHB.
