Larger interactive areas can be a good thing to strive for. This is to say a minimum of approximately 40 pixels may be beneficial for individuals who struggle with the smaller yet still WCAG-conformant size.

We should also be careful not to overcorrect by dropping in gigantic interactive elements in all of our work. If an interactive area is too large, it risks being activated by accident. This is important to note when an interactive element is placed in close proximity to other interactive elements and even more important to consider when activating those elements can result in irrevocable consequences.

There is also a phenomenon where elements, if large enough, are not interpreted or recognized as being interactive. Consequently, users may inadvertently miss them, despite large sizing.
