Thanks for visiting 5e Jump Calculator, a straightforward online tool built to solve one oddly specific D&D 5e problem: jumping.

If you’ve ever paused combat to flip through the Player’s Handbook, argued over whether a running start is enough, or tried to remember which stats affect jump distance, you’re in the right place.

So, What Does This Site Do?

5e Jump Calculator is a no-frills calculator that automates the D&D 5e jump math so you don’t have to.

You plug in your character’s stats—like Strength score, height, and a few relevant conditions—and the calculator instantly shows your:

Long jump distance

High jump height

Maximum reach during a jump

Other useful jump-related numbers based on the official rules

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

The Story Behind the Site

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

As a Dungeon Master and player, I kept running into 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 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 was originally just a quick private tool, and then I decided to share it in case other tables were running into the same slowdown.

How It Works (In Plain Language)

This tool uses the official Dungeons & Dragons 5th Edition jumping rules found in the Player’s Handbook. In simple terms, it:

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

Accounts for running vs standing jumps

Uses your height for realistic reach calculations

Respects the rules as written, without adding homebrew assumptions

You don’t have to memorize any of that. The calculator handles it and gives you the final, table-ready numbers.

How to Use It at Your Table

5e Jump Calculator is meant to be:

Simple enough to use during combat

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

Design encounters with realistic jumps in mind

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 steal the spotlight.

Future Plans

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

Support more edge cases and optional rules

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

Thanks for stopping by. I hope it saves you a few minutes—and a few arguments—every .
