5e Jump Calculator
Thanks for visiting 5e Jump Calculator, a small online tool built to solve one oddly specific D&D 5e problem: jumping.
If you’ve ever paused combat to flip through the Player’s Handbook, debated if that chasm is actually jumpable, or tried to reconstruct from memory which stats affect jump distance, this site is for you.
What Is 5e Jump Calculator?
5e Jump Calculator is a no-frills calculator that automates the D&D 5e jump math so you don’t have to.
You enter a few details about your character—including Strength, height, and situational modifiers—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 back-of-the-napkin math, no rules confusion—just straightforward outputs you can rely on.
Why I Built This Tool
This site was inspired by actual game-night problems.
As a DM who also plays regularly, I often hit the same situation:
Someone wants to clear a gap, leap to a ledge, or vault over an obstacle, we all pause to look up the details.
The 5e rules for jumping are straightforward, just not when you’re under time pressure. I didn’t want to keep re-explaining the same rule, so I took the obvious next step: I built a calculator.
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 just as tired of flipping pages mid-session.
How the Calculator Handles the Rules
This tool follows the official Dungeons & Dragons 5th Edition jumping rules as written in the PHB.
