5e Jump Calculator

You’ve found 5e Jump Calculator, a small online tool designed to tackle a surprisingly fiddly D&D 5e rule: working out jump distances.

If you’ve ever been the DM who paused combat to flip through the Player’s Handbook, argued over how far a character can really leap, or tried to remember which stats affect jump distance, this site is for you.

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:

Long jump distance

Maximum high jump

Effective reach while jumping

Other useful jump-related numbers based on the official rules

No back-of-the-napkin math, no rules confusion—just clear results you can rely on.

The Story Behind the Site

This site was the result of actual game-night problems.

As a Dungeon Master and player, I often hit the same situation:

A player asks, "Can I make that jump?" and the entire table stalls while we check the rules.

The 5e rules for are simple on paper but annoying in the moment. I didn’t want to keep re-explaining the same rule, so I did the sensible nerd thing: I built a calculator.

5e Jump Calculator began as something I used just for my home games, and then I decided to share it in case other tables were running into the same slowdown.

Under the Hood (Without the Jargon)

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

Accounts for running vs standing jumps

Uses your height for realistic reach calculations

Sticks closely to RAW and avoids house-rule shortcuts

You don’t need to know the exact formula. The calculator does the work and gives you the final, table-ready numbers.

Making the Most of the Calculator

5e Jump Calculator is meant to be:

Quick enough for live play

Understandable even if you’re new to 5e

Trustworthy enough for rules-focused groups

You can use it to:

Check whether a character can clear an obstacle before they commit

Design encounters with realistic jumps in mind

Keep cinematic moments moving without arguing over distances

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 calculates jumps accurately and clearly.

In the future, I may:

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 want to request a feature, you’re welcome to contact me. This site is for DMs and players like you, and your input directly guides future changes.

Thanks for checking out 5e Jump Calculator. May it help your party jump a little farther and your rules debates be a little shorter.
