Make Your Crosshair Thicker or Thinner

Open the Crosshair Texture

Find the crosshair PNG file in your resource pack's textures/gui/ folder. Open it with an image editor that supports transparency, like GIMP, Photoshop, or even Paint.NET.

Adjust the Line Thickness

The square crosshair is drawn as an outline. To make it thicker:

• Select the outline pixels
• Use the brush or pencil tool to add extra pixels around the existing lines
• Work carefully to keep the square shape symmetrical

To make it thinner:

• Erase pixels from the outer edge of the lines
• Reduce the outline to a single-pixel border if desired

Maintain the Square Shape

Ensure all four sides of the square remain even. Check corners especially — they should meet cleanly without gaps or overlaps.

Save and Test

Save your edited PNG file, then load Minecraft. The new crosshair thickness should display immediately in your game view. If the change is too subtle or too extreme, edit the file again and reload.
