5e Jump Calculator
You’ve found 5e Jump Calculator, a straightforward online tool built to solve one oddly specific D&D 5e problem: figuring out jumps.
If you’ve ever been the DM who stopped a session to dig through the PHB, argued over whether a running start is enough, or tried to reconstruct from memory which stats affect jump distance, 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 immediately calculates your:
Maximum long jump distance
High jump height
Effective reach while jumping
Other useful jump-related numbers based on the official rules
No page-flipping, no rough estimates—just clear results you can rely on.
Why This Calculator Exists
This site was the result of actual game-night problems.
As a DM who also plays regularly, I kept running into 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 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 problem.
How It Works (In Plain Language)
This tool uses the official Dungeons & Dragons 5th Edition jumping rules as written in the PHB.
