Isn’t everything better with a friend? Pairing things up in this week’s sites we like.

Daniel Eden has pulled together another gorgeous collection of font profiles, this time featuring a catalogue of serif and sans pairings from Typekit. As educational as it is effective, this site explores how “twin” fonts such as Freight Text and Freight Sans naturally balance one another when used on the same page.

On the clean, appealing Karma website, FF Din lends an upbeat style to the body text, with Proxima Nova Alt neatly punctuating each section. Karma’s mobile hotspots are designed to be shared with friends, and they express this simple idea effectively and with optimism on this smoothly designed site.

As Harmonizr aims to make modern group collaborations simpler and more fun to manage, their website leads by example, balancing the distinct personalities of FF Meta, Myriad, and Bello into one cohesive and dynamic message.

That’s all for this week; share sites that you like in the comments!
