How to Show Coordinates in Minecraft (Java and Bedrock)

Guide Java Bedrock

Quick answer: Java: press F3 - your X, Y and Z are in the debug screen. Bedrock: enable Show Coordinates in the world settings (no cheats needed). X/Z are your horizontal position, Y is height - diamonds live around Y=-59.

What you need

Java: a keyboard (F3)
Bedrock: world settings access (owner or operator)
No cheats required on either edition

Step by step

Java: press F3 in-game. The debug overlay appears - look for the XYZ line near the top left. Press F3 again to hide it.
Read it right: X runs east(+)/west(-), Y is height, Z runs south(+)/north(-). Your block position is the rounded-down value.
Java extras: F3 + G shows chunk borders, F3 + B shows hitboxes, F3 + Q lists all debug shortcuts. On some laptops F3 needs Fn + F3.
Bedrock: open the world settings (pause > Settings, or the pencil icon on the world list) and toggle Show Coordinates on. They display permanently at the top left.
Bedrock without cheats: the Show Coordinates toggle is a world setting, not a cheat - achievements stay enabled. The copy-coordinates button next to it puts your position in chat.
Use them: write down base coordinates, mark diamonds level (Y=-59 in current versions), and navigate back home by walking toward your saved X and Z.
Multiplayer: server rules may hide the F3 coordinates (reduced debug info). Bedrock servers and Realms respect the world setting controlled by the owner.

Java vs Bedrock

Java shows coordinates via F3 with no setting needed. Bedrock needs the world toggle, which the world owner controls - on Realms ask the owner to enable it.

Versions: F3 debug screen since early Java; Show Coordinates toggle in Bedrock since 1.8. Both work in all current versions.

Frequently asked questions

F3 does nothing - why?

On laptops the function row often needs Fn + F3. Some keyboards map F3 to brightness or volume - check your Fn lock. In-game, make sure no chat window is open.

Why does my server hide coordinates?

Java servers can enable reducedDebugInfo, which strips coordinates from F3 for everyone. It is a server-side rule - only the owner can change it (gamerule reducedDebugInfo false).

What Y level should I mine at?

For diamonds in current versions, Y=-59 (just above bedrock, watching for lava). For iron, mountain tops and Y=16; for coal, high mountains; for ancient debris in the Nether, Y=15.
