Welcome to 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 stopped a session to flip through the Player’s Handbook, argued over how far a character can really leap, or tried to reconstruct from memory how Strength and movement interact, you’re in the right place.

So, What Does This Site Do?

5e Jump Calculator is a that automates the D&D 5e jump math so you don’t have to.

You provide basic character info—like Strength score, height, and a few relevant conditions—and the calculator immediately calculates your:

Long jump distance

High jump height

Maximum reach during a jump

Other useful jump-related numbers based on the official rules

No page-flipping, no rough estimates—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 DM who also plays regularly, I kept noticing the same situation:

A player asks, "Can I make that jump?" and the entire table stalls while we check the rules.

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 made a dedicated tool.

5e Jump Calculator started as a personal helper, and then I turned it into a site so others could use it in case other tables were just as tired of flipping pages mid-session.

Under the Hood (Without the Jargon)

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 to set how far and how high you can jump

Considers whether you have a running start

Uses your height for realistic reach calculations

Respects the rules as written, without adding homebrew assumptions

You never have to think about the math directly. The calculator handles it and outputs just what you need for play.

How to Use It at Your Table

5e Jump Calculator is meant to be:

Fast enough to use mid-session

Understandable even if you’re new to 5e

Reliable for tables that like to follow RAW

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

Type in the numbers and let the calculator handle the rest. It’s meant to get out of the way, not steal the spotlight.

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

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

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