What fonts are good for a UI?

I know this is a very opinion based question, but I will ask it anyway. What fonts are good for a user interface? I have been looking through fonts but they are mostly either too simple and boring, or too hard to read and not simple enough. I know there is not a single answer, but can anyone give websites or what to look for?

Fonts can be really dependant on what style you want for your game.

Id say the most important thing for it is readability. You don’t want a font that is hard to read, it will make the user at the very least have to concentrate on the text. That’s a case for sore eyes right there. This means you might want to follow the logics of web design and get a real easy to read font. Reading should not be a chore. Things like HP or ammunition or whatnot need to be readable at a glance.

But if you are going for something more fantasy, period or sci-fi. Then an appropriate font should be used, dont be using some US army style stencil font in a lord of the rings style hack and slash. Immersion breaking.

Google fonts have helped me on web dev a number of times. There are many font sites out there 1001fonts for example. Just note, fonts as with anything created will come with a licence. I suggest reading it to ensure its usable in your current project.

What type and style of game are you making? if you dont mind me asking? Whats the world-theme?

DaFont is a good website for free fonts and so is 1001Fonts which was mentioned above. Just remember if you are using a font in Unity it either has to be OpenType or TrueType font format.

Personally I feel that San-Serif fonts work best for readability.

Just not Times New Roman. Also don’t use anything wacky that gets tiring on your eyes like Cosmic Sans, if there’s a lot to read.

Also, dafont.com is superior to 1001 fonts because you can filter by permissions. 1001 fonts just says you have to look at the downloaded readme of a font and if it says nothing about terms for commercial products, you can’t use it without trying to contact the creator.
