You’ve found 5e Jump Calculator, a straightforward online tool created to fix a common D&D 5e table slowdown: figuring out jumps.

If you’ve ever been the player who halted the action to look up the exact jumping rules, debated how far a character can really leap, or tried to remember which stats affect jump distance, this site is for you.

So, What Does This Site Do?

5e Jump Calculator is a simple online helper that takes the 5e jump rules and does the math for you.

You plug in your character’s stats—including Strength, height, and situational modifiers—and the calculator spits out your:

Maximum long jump distance

Maximum high jump

Effective reach while jumping

Key distances based on the 5e rules as written

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

Why This Calculator Exists

This site was inspired by repeated rules questions at the table.

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

Someone wants to clear a gap, leap to a ledge, or vault over an obstacle, we all pause to look up the details.

The 5e rules for jumping aren’t especially complicated, but they are easy to forget. 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 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.

How the Calculator Handles the Rules

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

Accounts for running vs jumps

Factors in your height and reach where appropriate

Sticks closely to RAW and avoids house-rule shortcuts

You never have to think about the math directly. The calculator handles it and gives you the final, table-ready numbers.

Using This Tool During Play

5e Jump Calculator is meant to be:

Quick enough for live play

Clear enough for new players

Accurate enough for rules lawyers

You can use it to:

Check whether a character can clear an obstacle before they commit

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 fade into the background, not become the focus of the session.

What’s Next?

Right now, 5e Jump Calculator is kept lean on purpose: it calculates jumps accurately and clearly.

In the future, I may:

Expand into other movement calculators

Cover more special abilities and conditions

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

If you spot something off, 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 input directly guides future changes.

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