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

If you’ve ever halted the action to look up the exact jumping rules, debated whether a running start is enough, 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 free web tool that takes the 5e jump rules and does the math for you.

You enter a few details about your character—such as Strength, height, and whether you have a running start—and the calculator instantly shows your:

Long jump distance

High jump height

Maximum reach during a jump

Key distances based on the 5e rules as written

No guesswork, no mid-session rule dives—just straightforward outputs you can rely on.

Why This Calculator Exists

This site was born from real table frustration.

As a Dungeon Master and player, I often hit 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 are simple on paper but annoying in the moment. 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 began as something I used just for my home games, and then I turned it into a site so others could use 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 laid out in the core rules. In simple terms, it:

Uses your Strength score to determine base jump distances

Considers whether you have a running start

Factors in your height and reach where appropriate

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.

Making the Most of the Calculator

5e Jump Calculator is meant to be:

Quick enough for live play

Clear enough for new players

Reliable for tables that like to follow RAW

You can use it to:

Verify a jump before the roll

Plan interesting movement options during encounter prep

Keep cinematic moments moving without arguing over distances

Type in the numbers and let the calculator handle the rest. It’s meant to get out of the way, not steal the spotlight.

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 plan to:

Expand into other movement calculators

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, I’d love to hear from you. This site is meant to make your games smoother, and your feedback helps shape what it becomes next.

Thanks for stopping by. I hope it saves you a few minutes—and a few arguments—every session.
