You’ve found 5e Jump Calculator, a small online tool created to fix a common D&D 5e table slowdown: working out jump distances.

If you’ve ever paused combat to look up the exact jumping rules, argued over how far a character can really leap, or tried to remember which stats affect jump distance, this tool was built with you in mind.

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 enter a few details about your character—including Strength, height, and situational modifiers—and the calculator immediately calculates your:

Long jump distance

High jump height

Maximum reach during a jump

Key distances based on the 5e rules as written

No back-of-the-napkin math, no rules confusion—just straightforward outputs you can rely on.

The Story Behind the Site

This site was born from real table frustration.

As a D&D fan who runs and joins games, I often hit the same situation:

A player asks, "Can I make that jump?" and 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 started as a personal helper, and then I cleaned it up and put it online in case other tables were running into the same problem.

How It Works (In Plain Language)

This tool implements 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

whether you have a running start

Uses your height for realistic reach calculations

Sticks closely to RAW and avoids house-rule shortcuts

You don’t have to memorize any of that. The calculator takes care of it and gives you the final, table-ready numbers.

Using This Tool During Play

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

Plan interesting movement options during encounter prep

Resolve player stunts without bogging things down

Open the site, fill in the fields, and you’re done. It’s meant to support your game quietly, not become the focus of the session.

Where This Might Go

Right now, 5e Jump Calculator is focused on doing one thing well: it handles jump distances cleanly.

In the future, I may:

Expand into other movement calculators

Cover more special abilities and conditions

Improve the layout and usability based on feedback

If you find a bug, or if you have an idea for improvement, I’d love to hear from you. 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. Here’s hoping it keeps your sessions moving and your jumps heroic.
