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

Edited by Aimie Carlson || By Janet White || Published on January 7, 2024
An edge is the sharp or distinct boundary of a surface, while a side is a flat, broader surface of an object or concept.

## Key Differences

An edge is typically defined as the sharp or distinct boundary of a surface, often where two surfaces meet, creating a line or border. A side, in contrast, refers to a flat or curved surface of an object, extending between its edges. The edge is more about the boundary, while the side is about the face or surface.
When interacting with objects, the edge is often perceived as a line or a point of transition, potentially sharp or distinct. On the other hand, a side is viewed as a broader area or surface, providing a sense of the object's shape and size. The edge is a point of demarcation, while the side is a zone of extension.
In practical terms, the edge of an object can be crucial for cutting or joining, serving as a point of interaction. The side of an object often serves for support, display, or containment, highlighting its functional versatility. The edge is about interaction and precision, whereas the side is about utility and space.
Symbolically, an edge can represent a boundary, limit, or a point of transition, often used metaphorically to describe critical or extreme conditions. A side, however, can symbolize a stance, perspective, or affiliation, denoting inclusivity or belonging. The edge symbolizes a limit or transition, while the side represents position or alignment.
In geometry, an edge is a line where two faces of a three-dimensional figure meet, playing a crucial role in defining shape. A side, however, is a single face of a two- or three-dimensional figure, contributing to the figure’s overall form. The edge is about convergence and delineation, while the side is about form and extent.
