An Easy & Proven Way to Build Good Habits
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.
Interactive Area Sizing Is As Much An Art As It Is A Science
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.

Many people would say that it is absolute madness to keep on doing the same thing, time after time, expecting to get a different result or for something different to happen.
There is no magic number or formula to get you that perfect Goldilocks “not too small, not too large, but just right” interactive area size. It requires knowledge of what the people who want to use your service want, and how they go about getting it.
The best way to learn that? Ask people.
Accessibility research includes more than just asking people who use screen readers what they think. It’s also a lot easier to conduct than you might think! For example, prototypes are a great way to quickly and inexpensively evaluate and de-risk your ideas before committing to writing production code.
