Non-zooming sites can (and should) honour your system-wide font-size setting, giving you the ability to use the system&#x27;s settings to achieve uniformly comfortable reading experiences across websites and apps.<p>Zooming doesn&#x27;t do much to give users much control over the reading experience -- iOS does not let users set or change the viewport size, so everyone gets the same columns to zoom into&#x2F;out of.<p>If you want text bigger than the single size the designer decided on, you&#x27;re forced to scroll along each line of text -- which is a terrible experience.<p>If you wanted it smaller, zooming out won&#x27;t &#x27;reflow&#x27; the layout, so you&#x27;ll just be losing screen real estate to peripheral content.
