For iOS, Apple’s Human Interface Guidelines recommend a minimum tap target size of 44x44pt.^[[1]] This applies to interactive elements like buttons, links, and icons, ensuring they are large enough to be tapped comfortably without accidental taps on nearby elements.

This size requirement ensures that users, including those with larger fingers or other accessibility needs, can interact with the app efficiently. It’s important to note that this is a minimum size, and increasing the tap target size can improve usability, especially in cases where the user interface is dense or includes many small controls.
