I can't display the chunk borders, even if I hit F3 + G. How do I get them to show up?

  • Using any mods? On a server?

  • This has never worked for me in optifine 1.8.8. Is that what you were using? Jan 23, 2021 at 16:58

I know that sometimes you need to hold down the function key (Fn on most keyboards) for the F keys to work. Try Fn+F3+G.

  • No its Not That It says "Chuck borders: shown", I have Reset My Computer And Minecraft, and it doesn't Show Up. Please help me! Mar 6, 2017 at 1:30

Go into chat settings and disable reduced debug info.
It should re-enable the following:

  • Chunk borders
  • Bounding boxes
  • Coordinates
  • Block info
  • Chunk info.
  • Facing info.
  • Client and server light info.
  • Biome info.
  • Sound info.
  • Difficulty info.

And probably more.


  • Why is this downvoted? It actually solved it for me.

  • Wow, I am so glad I finally looked this up because I would never have considered displaying the boundaries of chunks in game to be controlled by something in chat settings. Thank you. Oct 13, 2020 at 1:08

Maybe you have the lock key on. Try unlocking it by pressing fn + lock key (esc key) and then pressing fn + f + 3


I know this post is old, but I had this problem today and I couldn't find the answer easily. The problem is while pressing fn+F3 it doesn't understand the G, so while pressing fn+F3 release the fn then press G, it worked for me, I hope it works for whoever lands on this post.


One of the MC devs (Dinnerbone) has an online tool that allows you to calculate chunks. https://dinnerbone.com/minecraft/tools/coordinates/


The lines of the chunk border appear virtually invisible when running shaders. Simply, turn off your shaders if you're running them


Well, this can be the thing causing the issue: A broken keyboard. I used to play Minecraft on my laptop and the function keys didn't work. Make sure that your keyboard is working.

  • Are you sure you weren't just supposed to be holding Fn? If it's a laptop then probably. You're just using your keyboard wrong; it's not broken.

On some computers, it is just F3+G but on mine is an HP and I use fn+F3+G
