How to Disable Auto Zoom for Input Controls on iPhone

If you’re building a website and testing it on an iPhone, you may have encountered an annoying issue: when typing in input fields, the page unexpectedly zooms in. This is a common behavior on iPhones when the font size in the input field is smaller than 16 px. Safari, the default browser on iPhones, automatically zooms in to make text easier to read.

The good news is that you can easily prevent this auto-zooming behavior with a simple solution. In this guide, we’ll walk you through the steps to disable auto zoom for input fields on iPhones, so users can type without any disruptions.
