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.
