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

If you’ve ever been the DM who paused combat to dig through the PHB, debated how far a character can really leap, 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 provide basic character info—including Strength, height, and situational modifiers—and the calculator spits out your:

Maximum long jump distance

High jump height

Effective reach while jumping

Key distances based on the 5e rules as written

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

The Story Behind the Site

This site was the result of repeated rules questions at the table.

As a D&D fan who runs and joins games, I kept noticing 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 found myself reaching for the PHB over and over again, so I took the obvious next step: I wrote a little web app.

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 uses 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

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 does the work and outputs just what you need for play.

Making the Most of the Calculator

5e Jump Calculator is meant to be:

Quick enough for live play

Accessible for beginners

Trustworthy enough for rules-focused groups

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

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

What’s Next?

Right now, 5e Jump Calculator is deliberately simple: it solves the jump problem and stops there.

In the future, I plan to:

Expand into other movement calculators

Cover more special abilities and conditions

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 for DMs and players like you, and your input directly guides future changes.

Thanks for using 5e Jump Calculator. Here’s hoping it keeps your sessions moving and your jumps heroic.
