# Boundary vs. Limit — What's the Difference?

By Maham Liaqat & Fiza Rafique — Updated on March 12, 2024

**A boundary is a physical or conceptual line that marks the edge of an area, while a limit is a point or level beyond which something does not or cannot extend or pass.**

## Key Differences

Boundaries often refer to the demarcation lines that define the edges of geographical areas, properties, or conceptual spaces, indicating where one thing ends and another begins. For example, property lines are physical boundaries, while rules of a game can be seen as conceptual boundaries. Limits, on the other hand, are about extents or capacities, defining how far something can go or how much is allowable. They can apply to quantities, capacities, capabilities, or ranges of action. For instance, the speed limit indicates the maximum speed allowable, and a person's endurance might have a limit.

In the context of relationships or social interactions, boundaries are about setting and respecting personal space, preferences, and comfort levels, often crucial for healthy interactions. Limits in these contexts might refer to the extent to which one is willing or able to tolerate certain behaviors or actions.

Mathematically, boundaries are used to define the edges of shapes or regions, such as the boundary of a circle. Limits in mathematics, however, are a fundamental concept in calculus, referring to the value that a function or sequence "approaches" as the input or index approaches some value.

While boundaries can be negotiated, expanded, or redefined, limits are often more rigid, representing a maximum capacity or extent that cannot be exceeded without consequences. For example, expanding a garden might involve moving a boundary fence, but exceeding the physical limit of how much weight a bridge can hold has inherent dangers.

Both concepts play critical roles in various fields, from geography, law, and psychology to mathematics, physics, and engineering, helping to organize, understand, and navigate complex systems and interactions.
