About This Calculator
The Minecraft End Portal Finder helps you locate the End Portal in your Minecraft world without any mods or cheats. By throwing just two Eyes of Ender from different locations and recording their coordinates and direction, you can triangulate the exact position of the nearest stronghold's End Portal.
The calculator uses a standard triangulation formula. The Minecraft bearing (measured in degrees clockwise from south) is automatically converted to a cartesian angle by adding 90 degrees. The intersection of the two directional lines gives the portal coordinates: X3 = ((Z1 − Z2) + X2 × tan(θ2) − X1 × tan(θ1)) / (tan(θ2) − tan(θ1)) and Z3 = (Z1 × tan(θ2) − Z2 × tan(θ1) + (X2 − X1) × tan(θ2) × tan(θ1)) / (tan(θ2) − tan(θ1)).
The tool works for both Java Edition (using the F3 debug screen for precise bearings) and Bedrock Edition (using a ground compass method for visual bearing estimation). Results include the portal's X and Z coordinates plus the distance in blocks from each throw location. After your first triangulation, we recommend taking two more measurements about 50 blocks apart near the estimated area for pinpoint accuracy.
Frequently Asked Questions
How does the Minecraft End Portal Finder work?
Throw two Eyes of Ender from different locations at least a few hundred blocks apart. Note the X, Z coordinates and the bearing (direction in degrees clockwise from south) for each throw. The calculator uses a triangulation formula to compute the intersection point, giving you the approximate End Portal coordinates.
How accurate is the End Portal Finder?
Accuracy depends on how precisely you measure the bearing. Using the debug screen (F3 on Java Edition) gives the most accurate results. With a ground compass method on Bedrock Edition, expect an error of 50–100 blocks for portals over 500 blocks away. After the first triangulation, take two more measurements about 50 blocks apart near the estimated location for higher precision.
How do I measure the bearing in Minecraft?
On Java Edition, press F3 to open the debug screen — the first number in brackets (e.g., -90, 24) is your horizontal facing direction in degrees clockwise from south. On Bedrock Edition, build a 15×15 ground compass with markers at 7-block intervals and estimate the direction visually using the compass diagram.
What if the calculator says the bearings are parallel?
If the two Eye of Ender throws are nearly parallel, the triangulation cannot find a unique intersection point. Move to a location that gives a wider angle between the two bearings — ideally at least 30 degrees apart — and throw again.
How many Eyes of Ender do I need?
You need at least 2 Eyes of Ender for the initial triangulation, but you will likely need more for subsequent refinements. Each throw consumes one Eye of Ender, though some may drop and be reusable. Carry at least 12–15 Eyes of Ender for a full search.
Does this work in both Java and Bedrock Edition?
Yes. The coordinate system and bearing measurement work the same way in both Java and Bedrock editions of Minecraft. Java players can use the F3 debug screen for exact bearings, while Bedrock players can use the ground compass method described in the tutorial.
How do I convert the Minecraft angle for the triangulation formula?
The calculator handles the conversion automatically. The formula adds 90 degrees to convert Minecraft bearings (clockwise from south) to cartesian angles (counterclockwise from east). Simply enter the bearing you see on screen and the calculator does the rest.
Can I share my triangulation results?
Yes. All input values are saved in the page URL, so you can copy the URL and share it with friends or save it to come back to your calculation later.
