PortalMath by Fox Studios

PortalMath

Plan portal travel with clear coordinate projections.

Look directly at an active Nether portal to see its approximate equivalent horizontal coordinates in the other dimension.

Features

• Automatic display while targeting an active portal within eight blocks.
• Both Overworld-to-Nether and Nether-to-Overworld calculations.
• Correct handling of negative coordinates.
• A compact, transparent display with small game-font text.
• Uses the targeted portal block as a clearly labeled source anchor.
• Hides when looking away, opening a menu, or hiding the HUD.
• Local settings to disable the display or shorten its range.

A useful estimate

PortalMath divides horizontal Overworld coordinates by eight, or multiplies Nether coordinates by eight. Displayed coordinates are rounded down to whole blocks. Height is not converted.

The result is a planning estimate, not a discovered portal link. Existing portals, linking rules, and placement can change the actual arrival location.
