Welcome to 5e Jump Calculator, a small online tool created to fix a common D&D 5e table slowdown: figuring out jumps.

If you’ve ever been the player who paused combat to flip through the Player’s Handbook, debated how far a character can really leap, or tried to reconstruct from memory exactly how the jumping math works, this site is for you.

What This Tool Is All About

5e Jump Calculator is a simple online helper that turns the official 5th Edition jumping rules into instant numbers.

You provide basic character info—including Strength, height, and situational modifiers—and the calculator immediately calculates your:

Maximum long jump distance

Maximum high jump

Maximum reach during a jump

Other useful jump-related numbers based on the official rules

No page-flipping, no rough estimates—just clean numbers you can rely on.

The Story Behind the Site

This site was the result of real table frustration.

As a DM who also plays regularly, I kept noticing 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 simple on paper but annoying in the moment. 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 was originally just a quick private tool, and then I decided to share it in case other tables were into the same problem.

How It Works (In Plain Language)

This tool uses the official Dungeons & Dragons 5th Edition jumping rules as written in the PHB. In simple terms, it:

Uses your Strength to set how far and how high you can jump

Accounts for running vs standing jumps

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 takes care of it and outputs just what you need for play.

How to Use It at Your Table

5e Jump Calculator is meant to be:

Quick enough for live play

Understandable even if you’re new to 5e

Reliable for tables that like to follow RAW

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

Type in the numbers and let the calculator handle the rest. It’s meant to support your game quietly, not slow you down with options.

Where This Might Go

Right now, 5e Jump Calculator is kept lean on purpose: it handles jump distances cleanly.

In the future, I plan to:

Add more 5e movement-related tools

Support more edge cases and optional rules

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 built to help real tables, 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.
