About the Minecraft End Portal Finder
In survival Minecraft, the only reliable way to locate a stronghold's End Portal without external tools is Eye of Ender triangulation: throw an Eye of Ender, watch which way it flies, and read the direction. One throw gives a direction, not a location — throw a second Eye from a different spot, and the point where the two sightlines cross is your estimated stronghold position. This calculator does that crossing-point math for you.
The formula
Each throw location is a point (X, Z) with a facing angle read from the F3 debug screen. Minecraft's yaw convention maps 0°/360° to south, 90° to west, 180° to north, and 270° to east, which converts to a unit direction vector of dx = −sin(angle) and dz = cos(angle). Each throw defines a ray: (x, z) + t·(dx, dz) for t ≥ 0. Solving the two rays' linear equations simultaneously for their intersection gives the estimated stronghold (X, Z), and the parameter t along each ray (which is exact since the direction vectors are unit length) doubles as the travel distance in blocks from that throw point.
How to get the best results
- Press F3, note your X and Z from the Block/XYZ line, throw an Eye of Ender, and read the yaw value after "Facing:" while sighting along the eye's flight path — that is the facing angle to enter.
- Walk at least 100-200 blocks between the two throw points. A short baseline amplifies any error in the angle reading into a much larger error in the crossing point.
- Aim for the two sightlines to cross at something closer to a right angle than a sliver — a very shallow crossing angle makes the intersection unstable even with careful readings.
- Treat the result as a strong estimate, not a guarantee: throw a third Eye near the calculated point to confirm before you commit to digging.
Practical context
The X, Z result marks roughly where the stronghold sits underground — it does not tell you the Y (depth), since strongholds can appear across a wide range of underground levels. Once you reach the estimated coordinates, dig or cave downward and listen/look for the stronghold's stone-brick corridors, then follow them to the portal room. In modern Minecraft versions, an in-game locator/compass feature can replace manual triangulation entirely; this calculator reproduces the classic manual method for versions or situations where that aid is unavailable.
