GOOGLE FONTS I have been using Google Fonts for a while now because they are so versatile. If I need to design one thing online and then add it to my slide deck, I am confident the fonts will work together. And they play nice with about every blog or site you could build. Oh, and did I mention most of these 810 different fonts are free to use? Yeah, people like free. And they like things that are insanely easy to use. Like this example that uses a mix of a few popular Google Fonts: Some of the most popular fonts on Venngage are bold Google Fonts, like Roboto from above or Open Sans.
