Terraria sets world size and difficulty only when a world is created, so an existing world keeps its own. To get a different size or difficulty on a FREAKHOSTING server, open Game settings, expand New world, enter a new World name, choose World size and World difficulty, click Review and save and start the server. It creates the new world on that start.

​
World sizes compared

The Terraria Wiki notes that small worlds generate, save and load faster, and that large worlds need more memory. New servers use Small.

​
Difficulties compared

New worlds on our servers use Journey unless you change World difficulty first. See Expert and Master drops for what the harder modes give you.

​
Before you start

  • Make a backup if you might want the current world back.
  • Your current world stays in /saves/Worlds. You can switch back to it later by its name.

​
How to create a world with a new size or difficulty

1

Open Game settings

Open your server in the Game Panel and click Game settings under GAME SETTINGS.
2

Expand New world

Click New world to expand it. These settings are “Used only when a world is created (the first start of a new world name).”
3

Enter a new World name

Type a name that doesn’t exist yet, for example expertworld. It becomes the file expertworld.wld. Up to 20 characters.
4

Choose size and difficulty

Pick World size (Small, Medium, Large) and World difficulty (Classic, Expert, Master, Journey). Optionally add a World seed.
5

Review, save and start

Click Review and save, then Save changes. Restart the server. The console shows world generation, then Server started.
You can set the same values on the Startup page: World Name, World Size (1 small, 2 medium, 3 large) and Difficulty (0 normal, 1 expert, 2 master, 3 journey).

​
How to switch back to your old world

Set World name back to the old name (the file name without .wld), save and restart. The server loads the existing world with its own size and difficulty.

​
Can I change difficulty inside a Journey world?

Yes, within limits. Journey worlds have an enemy difficulty slider from 0.5× to 3× (1× matches Classic, 2× Expert, 3× Master). Who may use it is set by Change the difficulty in Journey mode settings. It doesn’t turn the world into a Classic world, and Classic characters still can’t join.

​
Frequently asked questions

​
Why is my new world in Journey mode?

World difficulty was still Journey when the world was created. Pick another difficulty, enter a new World name and restart.

​
Can I make an existing world bigger?

No. Size is fixed when the world is created. Create a new world with a new name.

​
What world size should I pick for 2 players?

Any size works. Small loads fastest; Medium or Large give more space to explore. The game sets no player limit by size.

​
I changed difficulty but nothing happened. Why?

The world already existed, so it kept its difficulty. Use a new World name.
