Lato is a humanist sans-serif typeface designed by Łukasz Dziedzic. It was released in 2015. The name "Lato" is Polish for "summer". As of August 2018, Lato is used on more than 9.6 million websites, and is the third most served font on Google Fonts, with over one billion views per day.
Lato was created in 2010 for a Polish bank by Łukasz Dziedzic. When the bank changed its stylistic vision, he shelved the typeface, and released it later that year under the libre SIL Open Font License.
After Lato was added to Google Fonts it quickly gained popularity, becoming the third most used web font after Google's own Roboto and Open Sans, with over one billion views per day as of August 2018.
