About the Stronghold Calculator
When you throw an Eye of Ender, it flies toward the nearest stronghold. One throw tells you the direction, but not the distance. Two throws from different spots give you two lines, and the stronghold sits where they cross. That’s triangulation, and it’s how speedrunners find the end portal. This online stronghold calculator does the math for you.
What you get on this page:
- Stronghold X and Z from two throws
- Distance from your second throw
- Nether coordinates for fast travel
- Copy and go: a /tp command if cheats are on
How to Use the Stronghold Calculator
Step 1: Throw the First Eye
Throw an Eye of Ender and look straight at it. Press F3 and write down your X, Z, and the Facing angle: the first number in brackets after “Facing”, like -133.5. On Java, F3+C copies your position and angle.
Step 2: Walk Sideways
Walk at least 200 blocks at a right angle to the direction the eye flew. The farther apart your throws, the more precise the result.
Step 3: Throw the Second Eye
Throw again, look at the eye, and write down the new X, Z, and angle.
Step 4: Read the Result
Type both throws into the calculator. It shows the stronghold’s X and Z and how far away it is. Go there, throw one more eye to confirm, and dig down.
How Triangulation Works
| Throw | What you get |
|---|---|
| One throw | A direction, but not the distance |
| Two throws | Two lines that cross at the stronghold |
| Three throws | A check that the first two were accurate |
Each line starts at your position and points along your facing angle. The calculator finds where the two lines meet. If the lines are almost parallel, the crossing point is far off and less precise, so walk further sideways and throw again.
How Precise Is It?
A small aiming error grows with distance: 0.1° off adds up to tens of blocks a thousand blocks away. To get a precise result:
- Stand still and look exactly at the floating eye before you read the angle.
- Space the throws 200 to 500 blocks apart.
- Throw a third time near the result to confirm.
Will My Eyes Break?
Each throw has a 1 in 5 (20%) chance to break the eye. Bring extra Eyes of Ender. The end portal needs up to 12 to activate.
Stronghold Calculator vs Stronghold Finder
| Calculator | Stronghold finder | |
|---|---|---|
| Needs a seed | No | Yes |
| Needs Eyes of Ender | Yes, 2 or more | No |
| Works on Bedrock | Yes | Java positions only |
| Shows every stronghold | No, the nearest one | Yes, all rings |
If you know the seed, the stronghold finder is faster. If you don’t, or you play Bedrock, use this calculator.
Stronghold Calculator for Speedruns
Speedrunners throw once at spawn, travel a bit, throw again, then plug the numbers in. Divide the result by 8 and travel through the Nether to cut the trip.
Does It Work in the Nether?
No. Eyes of Ender don’t point anywhere in the Nether. Throw them in the Overworld, then convert the result to Nether coordinates for travel.

Frequently Asked Questions
What angle do I use?
The first number after “Facing” on the F3 screen, while you look straight at the floating eye.
My two eyes point to different strongholds. Why?
If you’re halfway between two strongholds, the eyes can pick different ones. Walk further toward one and throw again.
Does the stronghold calculator work on Bedrock?
Yes. Use the coordinates from Show Coordinates. Bedrock doesn’t show a facing angle on screen, so estimate the direction carefully or use a third throw to confirm.
Do I need a mod or download?
No. It works in your browser.
Final Thoughts
A stronghold calculator finds the end portal with just two Eyes of Ender. Throw, walk sideways, throw again, and let the math point you to the stronghold.
