Activating the Font Pack in Your Game
Enable the Resource Pack
Once installed, the font pack must be activated in your Minecraft launcher settings before it takes effect in-game.
1. Open Minecraft and go to Options → Resource Packs
2. Look for "Slightly Improved Font Resource Pack" in the Available list on the left
3. Click the arrow button to move it to the Selected list on the right
4. The pack should now appear above the Default pack in your active list
5. Close the menu and restart your world or server connection
Verify It's Working
After activation, check that the font has changed by opening your inventory, chat, or any text-heavy screen. The characters should appear slightly smoother and more refined than vanilla Minecraft's default blocky font. If text still looks the same, try moving the pack higher in the resource pack list (packs higher up take priority) or restarting the game entirely.
You can toggle the pack on and off anytime by moving it between the Available and Selected lists.
