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 player who stopped a session to dig through the PHB, debated how far a character can really leap, or tried to remember how Strength and movement interact, you’re in the right place.

What Is 5e Jump Calculator?

5e Jump is a no-frills calculator that takes the 5e jump rules and does the math for you.

You provide basic character info—including Strength, height, and situational modifiers—and the calculator immediately calculates your:

Long jump distance

Maximum high jump

Maximum reach during a jump

Other useful jump-related numbers based on the official rules

No page-flipping, no rough estimates—just clear results you can rely on.

Why This Calculator Exists

This site was inspired by actual game-night problems.

As a Dungeon Master and player, I kept noticing the same situation:

A character wants to do something cool and cinematic with a jump, we all pause to look up the details.

The 5e rules for jumping are straightforward, just not when you’re under time pressure. I didn’t want to keep re-explaining the same rule, so I did the sensible nerd thing: I wrote a little web app.

5e Jump Calculator started as a personal helper, and then I cleaned it up and put it online in case other tables were just as tired of flipping pages mid-session.

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 score to determine base jump distances

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 have to memorize any of that. The calculator does the work and shows you the result that matters at the table.

How to Use It at Your Table

5e Jump Calculator is meant to be:

Simple enough to use during combat

Clear enough for new players

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 steal the spotlight.

Where This Might Go

Right now, 5e Jump Calculator is kept lean on purpose: it solves the jump problem and stops there.

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

If you spot something off, or if you want to request a feature, 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 stopping by. Here’s hoping it keeps your sessions moving and your jumps heroic.
