Thanks for visiting 5e Jump Calculator, a tiny online tool designed to tackle a surprisingly fiddly D&D 5e rule: figuring out jumps.

If you’ve ever been the player who paused combat to dig through the PHB, argued over whether a running start is enough, or tried to remember which stats affect jump distance, this tool was built with you in mind.

So, What Does This Site Do?

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

You plug in your character’s stats—including Strength, height, and situational modifiers—and the calculator immediately calculates your:

Maximum 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.

Why This Calculator Exists

This site was the result of repeated rules questions at the table.

As a Dungeon Master and player, 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 are simple on paper but annoying in the moment. I was tired of re-reading the same paragraph every few sessions, so I did what many nerdy DMs do: I made a dedicated tool.

5e Jump Calculator was originally just a quick private tool, and then I turned it into a site so others could use it in case other tables were running into the same problem.

Under the Hood (Without the Jargon)

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 need to know the exact formula. The calculator handles it and shows you the result that matters at the table.

How to Use It at Your Table

5e Jump Calculator is meant to be:

Quick enough for live play

Accessible for beginners

Accurate enough for rules lawyers

You can use it to:

Verify a jump before the roll

Plan interesting movement options during encounter prep

Keep cinematic moments moving without arguing over distances

Open the site, fill in the fields, and you’re done. It’s meant to fade into the background, not steal the spotlight.

Future Plans

Right now, 5e Jump Calculator is kept lean on purpose: it calculates jumps accurately and clearly.

In the future, I might:

Add more 5e movement-related tools

Support more edge cases and optional rules

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

If you spot something off, or if you have an idea for improvement, feel free to reach out. This site is built to help real tables, and your input directly guides future changes.

Thanks for using 5e Jump . I hope it saves you a few minutes—and a few arguments—every session.
