Welcome to 5e Jump Calculator, a tiny online tool created to fix a common D&D 5e table slowdown: jumping.

If you’ve ever halted the action 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, you’re in the right place.

What Is 5e Jump Calculator?

5e Jump Calculator is a no-frills calculator that takes the 5e jump rules and does the math for you.

You provide basic character info—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 back-of-the-napkin math, no rules confusion—just clear results you can rely on.

The Story Behind the Site

This site was born from real table frustration.

As a DM who also plays regularly, I kept running into 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 are simple on paper but annoying in the moment. I was tired of re-reading the same paragraph every few sessions, so I did the sensible nerd thing: I made a dedicated tool.

5e Jump Calculator started as a personal helper, and then I cleaned it up and put it online in case other tables were just as tired of flipping pages mid-session.

Under the Hood (Without the Jargon)

This tool uses 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

Sticks closely to RAW and avoids house-rule shortcuts

You never have to think about the math directly. The calculator handles it and outputs just what you need for play.

How to Use It at Your Table

5e Jump Calculator is meant to be:

Simple enough to use during combat

Clear enough for new players

Trustworthy enough for rules-focused groups

You can use it to:

Check whether a character can clear an obstacle before they commit

Design encounters with realistic jumps in mind

Resolve player stunts without bogging things down

Just enter the stats and read the output. It’s meant to support your game quietly, not steal the spotlight.

Where This Might Go

Right now, 5e Jump Calculator is deliberately simple: it handles jump distances cleanly.

In the future, I might:

Expand into other movement calculators

Support more edge cases and optional rules

Polish the interface and add small quality-of-life features

If you spot something off, or if you have a suggestion, feel free to reach out. This site is built to help real tables, and your input directly guides future changes.

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