# Cubic Feet vs. Square Feet — What's the Difference?

By Tayyaba Rehman — Published on November 13, 2023
Cubic Feet measures volume in three dimensions, while Square Feet measures area in two dimensions.

## Key Differences

Cubic Feet is a unit of measurement that quantifies volume or capacity in three-dimensional space. In contrast, Square Feet is a unit of measurement that signifies area in two-dimensional space.
While Cubic Feet captures the breadth, length, and height of a space, Square Feet only represents its length and breadth. Thus, when measuring a room's floor space, one would use Square Feet, but to gauge its total volume, Cubic Feet would be the unit to consider.
The applications of these measurements differ, with Cubic Feet often used for storage or shipping capacities, and Square Feet for floor plans or land plots. Both measurements provide essential data, with Cubic Feet indicating how much a space can hold and Square Feet detailing the extent of a flat surface.
It's crucial to differentiate between these two as they serve different purposes. For example, if you're buying tiles for flooring, you'd need to know the Square Feet. But if you're purchasing a refrigerator, you might want to know its capacity in Cubic Feet.
Ultimately, while both Cubic Feet and Square Feet are vital measurements in construction, real estate, and various industries, understanding their distinction ensures accurate space and capacity evaluations.
