Is there any need to include some fonts in head or are they default?

Question

For my own case, is there any need to add the Roboto font as a link in the head tag or is already default in Chrome?

I'm interested only for Chrome.

Answer 1

Browsers don't install fonts they just reference what's available. Available being the keyword is different depending on the OS & Device the browser runs on.

Chrome on an Android device will likely have access to Roboto as Google uses it heavily for Material. However, Roboto is not installed by default on most desktop operating systems or iOS unless the user has made a choice to do so.

If you want to guarantee any font to be available you need to include it in your package or reference the font from a CDN like fonts.google.com
