A small icon can look tidy while being difficult to tap accurately. The usable area around the control and its distance from neighboring actions affect the experience on a touch screen.

Consider the complete target, including the space that responds to a tap. A frequently used action deserves room, and adjacent controls should not make an accidental choice easy. Check the arrangement with actual fingers on a narrow screen.

Keep other input methods in view too. The same control should have a clear label and a visible keyboard focus. A comfortable target supports ordinary variation in how someone holds, views, and interacts with the device.

A few starting points
  1. Check the actual interactive area.
  2. Leave space between adjacent actions.
  3. Try touch and keyboard interaction.

Try the idea in context.

Consider selecting a tiny link while holding a phone in one hand. A larger, well-spaced target can help the intended action remain easy to reach.

A thought for the next read.

Review the longest word and the least convenient condition. An interface should have room for the ordinary variations that a polished sample often leaves out.
