How to Make Undertale Fullscreen

Things seem ... a bit bigger, huh?

Undertale is still a brilliant game, nearly seven years after its initial launch. Developed by Toby Fox, who, as of writing, has gone on to develop two chapters of Deltarune, the story of a human who fell into a world of monsters is still incredibly purposeful to this day. It only makes sense that, according to Steam Charts, an average of more than 4,500 players have experienced — or re-experienced — the game in 2022 alone.

But, new players may be taken aback by the default 640×480 window size. It makes sense for players who are more accustomed to increasingly visual spectacles in gaming to want to increase that window size. If you aren’t a fan of that window size and would like to increase it, here’s how.

How to Increase Undertale Window Size

Good news! Making Undertale fullscreen is actually incredibly easy. If you have the game loaded up, all you need to do is hit F4 on the keyboard. What’s more, no quality seems to be sacrificed to increase the window’s size. It looks very natural based on a quick glance at the first few minutes of the game.

That’s all you need to know to increase the window size in Undertale. For more guides just like this, stick with Gamer Journalist!
