Minecraft (Java & Bedrock) — Nether Portal 8:1 Coordinate Linker & 3D Distance Collision Checker

Unofficial, ad-free second-screen companion calculator for Minecraft (Java & Bedrock).

Does Y-coordinate (altitude) divide by 8 for Nether portals?

No! Only X and Z divide by 8 when converting Overworld to Nether. Always match the Y-altitude as closely as possible when two portals sit within 128 Overworld blocks so 3D Euclidean distance picks the right frame.

How much obsidian is required for a clean Nether highway link?

A minimum 4×5 Nether portal frame uses 10 obsidian blocks if corners are skipped (14 with corners). Bring 20 obsidian and a Flint & Steel to build the exact paired frame inside the Nether.
