Thanks for visiting 5e Jump Calculator, a straightforward online tool created to fix a common D&D 5e table slowdown: working out jump distances.

If you’ve ever stopped a session to dig through the PHB, debated how far a character can really leap, or tried to reconstruct from memory exactly how the jumping math works, you’re in the right place.

What This Tool Is All About

5e Jump Calculator is a free web tool that takes the 5e jump rules and does the math for you.

You plug in your character’s stats—such as Strength, height, and whether you have a running start—and the calculator spits out your:

Long jump distance

High jump height

Maximum reach during a jump

Other useful jump-related numbers based on the official rules

No page-flipping, no rough estimates—just clean numbers you can rely on.

The Story Behind the Site

This site was inspired by real table frustration.

As a Dungeon Master and player, I kept running into the same situation:

A character wants to do something cool and cinematic with a jump, everyone stops to argue about the math.

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 what many nerdy DMs do: I built a calculator.

5e Jump Calculator was originally just a quick private tool, and then I turned it into a site so others could use it in case other tables were just as tired of flipping pages mid-session.

How It Works (In Plain Language)

This tool uses the official Dungeons & Dragons 5th Edition jumping rules as laid out in the core rules. 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 never have to think about the math directly. The calculator handles it and gives you the final, table-ready numbers.

How to Use It at Your Table

5e Jump Calculator is meant to be:

Fast enough to use mid-session

Understandable even if you’re new to 5e

Reliable for tables that like to follow RAW

You can use it to:

Verify a jump before the roll

Design encounters with realistic jumps in mind

Resolve player stunts without bogging things down

Type in the numbers and let the calculator handle the rest. It’s meant to fade into the background, not become the focus of the session.

Future Plans

Right now, 5e Jump Calculator is deliberately simple: it accurately and clearly.

In the future, I may:

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 have a suggestion, feel free to reach out. This site is built to help real tables, and your experience at the table is what matters most.

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