Thanks for visiting 5e Jump Calculator, a small online tool created to fix a common D&D 5e table slowdown: working out jump distances.

If you’ve ever been the player who halted the action to look up the exact jumping rules, argued over whether a running start is enough, or tried to remember how Strength and movement interact, this site is for you.

What This Tool Is All About

5e Jump Calculator is a simple online helper that takes the 5e jump rules and does the math for you.

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

Maximum long jump distance

High jump height

Effective reach while jumping

Other useful jump-related numbers based on the official rules

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

Why This Calculator Exists

This site was inspired by real table frustration.

As a Dungeon Master and player, 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 aren’t especially complicated, but they are easy to forget. 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 cleaned it up and put it online in case other tables were running into the same problem.

Under the Hood (Without the Jargon)

This tool implements the official Dungeons & Dragons 5th Edition jumping rules found in the Player’s Handbook. In simple terms, it:

Uses your Strength score to determine base jump distances

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 handles it and gives you the final, table-ready numbers.

Using This Tool During Play

5e Jump Calculator is meant to be:

Fast enough to use mid-session

Understandable even if you’re new to 5e

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 slow you down with options.

Where This Might Go

Right now, 5e Jump Calculator is deliberately simple: it solves the jump problem and stops there.

In the future, I plan to:

Add more 5e movement-related tools

Support more edge cases and optional rules

Improve the layout and usability based on feedback

If you find a bug, or if you want to request a feature, 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 Calculator. May it help your party jump a little farther and your rules debates be a little shorter.
