Welcome to 5e Jump Calculator, a tiny online tool built to solve one oddly specific D&D 5e problem: working out jump distances.

If you’ve ever been the DM who halted the action to dig through the PHB, debated how far a character can really leap, or tried to reconstruct from memory which stats affect jump distance, you’re in the right place.

What This Tool Is All About

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

You plug in your character’s stats—such as Strength, height, and whether you have a running start—and the calculator spits out your:

Maximum long jump distance

High jump height

Maximum reach during a jump

Key distances based on the 5e rules as written

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

Why This Calculator Exists

This site was inspired by actual game-night problems.

As a DM who also plays regularly, I often hit the same situation:

Someone wants to clear a gap, leap to a ledge, or vault over an obstacle, 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 was tired of re-reading the same paragraph every few sessions, so I took the obvious next step: I built a calculator.

5e Jump Calculator started as a personal helper, and then I cleaned it up and put it online in case other tables were running into the same problem.

How the Calculator Handles the Rules

This tool follows 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

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.

Making the Most of the Calculator

5e Jump Calculator is meant to be:

Fast enough to use mid-session

Clear enough for new players

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

Open the site, fill in the fields, and you’re done. It’s meant to support your game quietly, not steal the spotlight.

What’s Next?

Right now, 5e Jump Calculator is focused on doing one thing well: it handles jump .

In the future, I might:

Expand into other movement calculators

Cover more special abilities and conditions

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

If you notice an issue, or if you have a suggestion, feel free to reach out. This site is for DMs and players like you, and your input directly guides future changes.

Thanks for stopping by. Here’s hoping it keeps your sessions moving and your jumps heroic.
