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

If you’ve ever been the player who halted the action to dig through the PHB, argued over how far a character can really leap, or tried to remember how Strength and movement interact, this tool was built with you in mind.

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 enter a few details about your character—such as Strength, height, and whether you have a running start—and the calculator spits out your:

Long jump distance

Maximum high jump

Maximum reach during a jump

Key distances based on the 5e rules as written

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

Why This Calculator Exists

This site was inspired by repeated rules questions at the table.

As a DM who also plays regularly, I kept noticing the same situation:

Someone wants to clear a gap, leap to a ledge, or vault over an obstacle, we all pause to look up the details.

The 5e rules for jumping aren’t especially complicated, but they are easy to forget. I was tired of re-reading the same paragraph every few sessions, so I did what many nerdy DMs do: I built a calculator.

5e Jump Calculator was originally just a quick private tool, and then I cleaned it up and put it online in case other tables were running into the same slowdown.

How the Calculator Handles the Rules

This tool implements 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

Factors in your height and reach where appropriate

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.

Making the Most of the Calculator

5e Jump is meant to be:

Quick enough for live play

Accessible for beginners

Trustworthy enough for rules-focused groups

You can use it to:

Verify a jump before the roll

Design encounters with realistic jumps in mind

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 steal the spotlight.

Where This Might Go

Right now, 5e Jump Calculator is deliberately simple: 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 stopping by. May it help your party jump a little farther and your rules debates be a little shorter.
