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

If you’ve ever paused combat to look up the exact jumping rules, argued over if that chasm is actually jumpable, or tried to reconstruct from memory exactly how the jumping math works, this site is for you.

What Is 5e Jump Calculator?

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

You enter a few details about your character—like Strength score, height, and a few relevant conditions—and the calculator immediately calculates your:

Long jump distance

Maximum high jump

Effective reach while jumping

Other useful jump-related numbers based on the official rules

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

Why I Built This Tool

This site was born from repeated rules questions at the table.

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

A character wants to do something cool and cinematic with a jump, we all pause to look up the details.

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 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.

How It Works (In Plain Language)

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

Uses your height for realistic reach calculations

Respects the rules as written, without adding homebrew assumptions

You don’t need to know the exact formula. The calculator handles it and outputs just what you need for play.

Using This Tool During Play

5e Jump Calculator is meant to be:

Quick enough for live play

Understandable even if you’re new to 5e

Trustworthy enough for rules-focused groups

You can use it to:

Verify a jump before the roll

Plan interesting movement options during encounter prep

Resolve player stunts without bogging things down

Just enter the stats and read the output. It’s meant to fade into the background, not slow you down with options.

Future Plans

Right now, 5e Jump Calculator is focused on doing one thing well: it calculates jumps accurately and clearly.

In the future, I plan to:

Add more 5e movement-related tools

Cover more special abilities and conditions

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

If you spot something off, or if you have a suggestion, feel free to reach out. This site is for DMs and players like you, and your feedback helps shape what it becomes next.

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