You’ve found 5e Jump Calculator, a tiny online tool built to solve one oddly specific D&D 5e problem: figuring out jumps.

If you’ve ever been the DM who halted the action to dig through the PHB, argued over if that chasm is actually jumpable, or tried to reconstruct from memory which stats affect jump distance, you’re in the right place.

What This Tool Is All About

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:

Long jump distance

Maximum high jump

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.

The Story Behind the Site

This site was born from repeated rules questions at the table.

As a D&D fan who runs and joins games, I kept noticing 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 was tired of re-reading the same paragraph every few sessions, so I did the sensible nerd thing: I wrote a little web app.

5e Jump Calculator started as a personal helper, and then I decided to share it in case other tables were running into the same problem.

Under the Hood (Without the Jargon)

This tool follows the official Dungeons & Dragons 5th Edition jumping rules as written in the PHB. In simple terms, it:

Uses your Strength to set how far and how high you can jump

Accounts for running vs standing jumps

Uses your height for realistic reach calculations

Respects the rules as written, without adding homebrew assumptions

You don’t need to know the exact formula. The calculator handles it and gives you the final, table-ready numbers.

Using This Tool During Play

5e Jump Calculator is meant to be:

Fast enough to use mid-session

Accessible for beginners

Trustworthy enough for rules-focused groups

You can use it to:

Check whether a character can clear an obstacle before they commit

Plan interesting movement options during encounter prep

Resolve player stunts without bogging things down

Just enter the stats and read the output. It’s meant to support your game quietly, not become the focus of the session.

Where This Might Go

Right now, 5e Jump is kept lean on purpose: it solves the jump problem and stops there.

In the future, I might:

Add more 5e movement-related tools

Support more edge cases and optional rules

Improve the layout and usability based on feedback

If you notice an issue, or if you want to request a feature, feel free to reach out. This site is built to help real tables, and your feedback helps shape what it becomes next.

Thanks for using 5e Jump Calculator. May it help your party jump a little farther and your rules debates be a little shorter.
