If you are good with your fonts you would have likely of heard of Gotham, or how about Proxima Nova? These are incredibly widely used fonts, and because of which have a price tag. Gotham will cost you a whopping $269 and Proxima Nova costing $313. I’m not saying there not worth it, these fonts are gorgeous but are out of many peoples budget.
Thankfully there is a free font called Montserrat which is very similar and could certainly be used as a replacement. Whats best is that its a whole family of fonts. Pick and choose from whichever you like.
