Touch Target Size
The physical tappable area of every interactive element on a phone screen, and the clearance between it and its neighbours.
Analogy Mental model
An adult thumb is a blunt instrument. Two switches the size of grains of rice, placed side by side, will both get pressed at once every time.
In practice What you actually do
Follow the platform guidelines: a tap area of at least forty-eight pixels square, with at least eight pixels of empty space before the next target. Where a visual element must stay small, extend the invisible hit area with padding rather than enlarging the artwork.
Where people get burned Pitfalls
Pagination numbers, breadcrumb links, and dense footer link lists are the three places this fails most often. They are also among the cheapest things on a page to fix.
