roundedend

Roundedend is a design and geometry term referring to the termination of a stroke, path, or object with a curved end rather than a sharp point or a flat edge. It is used across fields such as graphic design, typography, user interface design, and mechanical drawing to create a softer, more approachable appearance and to reduce sharpness in physical or visual forms.

In practice, rounded ends are created by applying a radius to the end of a line or by capping the stroke with a circular or arc-shaped end. Common variants include single-ended rounded ends, double-ended or symmetric rounded ends, and pill or stadium shapes when both ends are rounded. In digital graphics, this effect can be implemented through stroke end caps or by modeling the end with a circular segment, and it is often described as a “round” end in contrast to “butt” or “square” ends.

Applications of rounded ends include buttons and controls in user interfaces, where rounded edges are associated with friendliness and approachability; signage and branding elements to convey softness or safety; and physical design where rounded terminations reduce snagging and stress concentrations. In typography and path-based design, rounding can influence legibility and the perceived weight of a stroke, particularly at small sizes or low resolutions.

Related concepts include fillet and chamfer in mechanical design, as well as the broader idea of line caps and stroke styling in vector graphics. Rounded ends are valued for aesthetics, ergonomics, and functional considerations in both digital and physical forms.
