You’ve found 5e Jump Calculator, a straightforward online tool built to solve one oddly specific D&D 5e problem: figuring out jumps.

If you’ve ever been the DM who halted the action to dig through the PHB, argued over if that chasm is actually jumpable, or tried to remember which stats affect jump distance, this tool was built with you in mind.

What Is 5e Jump Calculator?

5e Jump Calculator is a no-frills calculator that turns the official 5th Edition jumping rules into instant numbers.

You enter a few details about your character—including Strength, height, and situational modifiers—and the calculator immediately calculates your:

Long jump distance

High jump height

Maximum reach during a jump

Key distances based on the 5e rules as written

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

Why This Calculator Exists

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

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

A character wants to do something cool and cinematic with a jump, the entire table stalls while we check the rules.

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 made a dedicated tool.

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 the Calculator Handles the Rules

This tool implements 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

Sticks closely to RAW and avoids house-rule shortcuts

You don’t need to know the exact formula. 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:

Simple enough to use during combat

Accessible for beginners

Trustworthy enough for rules-focused groups

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 fade into the background, not slow you down with options.

Future Plans

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

In the future, I might:

Add more 5e movement-related tools

Support more edge cases and optional rules

Improve the layout and usability based on feedback

If you notice an issue, or if you have an idea for improvement, I’d love to hear from you. This site is for DMs and players like you, and your input directly guides future changes.

Thanks for using 5e Jump Calculator. Here’s hoping it keeps your sessions moving and your jumps heroic.
