A handle and a hand

A handle is a small interface between an object and a person. Its curve, clearance, texture, and position work together. A handle that looks generous from the side may offer little room for fingers, while a visually modest loop may be comfortable because it sits at the right angle.

Compare familiar objects under ordinary conditions. Notice where pressure is concentrated and whether the wrist has to bend. A mug full of liquid behaves differently from an empty one, so keep the comparison safe and unhurried. Avoid drawing universal conclusions from one hand or one task.

Good observation includes the setting: wet hands, gloves, limited grip, or the direction an object is lifted. There may be no single ideal handle. A useful design makes its intended action easier to understand and carry out.
