Okay, so I threw 10,000 fonts at you last time
10,000 fonts is kind of a waste of time, because...sadly...your website only needs three typefaces, tops. Here is my extremely simplified font selection rhetoric, which will probably piss off some other designers who want me to tell you all about kerning and x-heights and stuff, but I don't think that's necessary.
You need one font for your body copy. You know, the stuff you're reading right now. You want it to be legible, first. But there are tons of legible choices, so you still have flexibility and room for (a little bit) of personality. Serif faces (the kind with little feet on the ends) are frequently used for body copy, but that's not a hard and fast rule.
You need one font for your headlines. (It doesn't actually have to be a different typeface than the body copy--a different weight can be sufficient).
If you're using two different typefaces, make sure they're pretty different. Maybe one is heavy and one is thin. One is serif and one is sans serif. One is simple, the other complex. Difference doesn't guarantee they'll look good together, but it's a start.
Soooooometimes you might need or want a third typeface for special text on your website or postcard. Like you just don't think your work is fully encapsulated with your super sleek two fonts. Like something wild and crazy. Remember: restraint in all things, especially display typefaces.
Here's a combo I built in Google Fonts, just for funsies:
Feel free to play around with different combos. The world of typography is vast and suuuuper nerdy. You can get lost! Have fun!
p.s. Do you have more questions about choosing a typeface? Wondering why you might choose one or the other? Let me know in the comments.
