So Valve made my steam fonts bigger.

So, it appears valve have made the fonts in steam chat larger. I hate large fonts.

So I HAD to make some changes.

You're looking for a file called steam.styles, I found mine at C:\Program Files\Steam\resource\styles

Open it up with notepad or something, ctrl+f and search for "size".

I just dropped all my friends and chat related ones down by 2, so changing 14 to 12, 16 down to 14 and so on.

I didn't change every single font, just a random amount, got bored, restarted steam and it was all nice again! You can find a copy of my steam.styles here: Steam.styles
