Windows 10 Insider Preview Build 21376 is now rolling out. The main feature included in this update is an entirely updated version of the Segoe UI font which Microsoft calls the “Segoe UI font variable.”

The original Sergio UI font was made for computers showing a 9pt (12px) font size. Over the years it has become increasingly popular to use larger-sized fonts. It’s not a connection with HD displays but rather the additional device screen-sized we use. For instance, often you will find a 17-inch laptop with the same screen ratio as a desktop. This can often be cured by using browser settings to zoom in and out to suit your desires; however, no such option is for general operating system usage.
