What this video covers
Target size is the size of a tappable or clickable element plus the space around it. If it’s too small or too crowded, users may miss it - due to fat fingers, tremors, small screens, or a moving bus - and a control they can’t reliably hit is effectively broken.
With the tiny targets you fumbled and hit the wrong one; size them up and the same task became effortless. Nothing changed but the box you had to land on. That margin for error - or the lack of it - is what target size buys, and it's invisible until it fails someone.
