 ## What is Mithril.js?
 
-A modern client-side JavaScript framework for building Single Page Applications. It's small (<!-- size -->9.17 KB<!-- /size --> gzipped), fast and provides routing and XHR utilities out of the box.
+A modern client-side JavaScript framework for building Single Page Applications. It's small (<!-- size -->9.14 KB<!-- /size --> gzipped), fast and provides routing and XHR utilities out of the box.
 
 Mithril.js is used by companies like Vimeo and Nike, and open source platforms like Lichess 👍.
