# Edge vs. Curve: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Updated on October 5, 2023
"Edge" refers to the sharp, defined boundary of a surface, while "Curve" describes a smoothly bent or arched line or surface.

## Key Differences

"Edge" often denotes a boundary or limit. It can represent the outermost line or border of an object or surface. "Curve," however, is not necessarily about boundaries, but about the form or bend of a line or surface.

The term "Edge" suggests a certain sharpness or definiteness. For instance, a piece of paper has distinct edges that one can touch and feel. In contrast, "Curve" implies a smooth, continuous bend, like that seen in a winding road or a gentle arc.

In geometric terms, "Edge" is typically a straight line, especially when discussing shapes like squares or rectangles. "Curve" does not have this limitation; it simply represents a line that isn't straight.

Functionally, an "Edge" might serve as a defining boundary or a point of separation. "Curve," on the other hand, often indicates a transition, a change in direction, or a deviation from straightness.

"Edge" and "Curve" have versatile applications in different contexts, from mathematics to art to everyday language. While both can describe aspects of an object or surface, "Edge" typically refers to boundaries, and "Curve" to bends or arches.
