The word square is one of those English words that can mean several completely different things. You may know it as a shape, but square meaning can change depending on whether you are talking about mathematics, geometry, a public place, everyday conversation, or slang.
In geometry, a square is a four-sided shape with four equal sides and four right angles. In mathematics, to square a number means to multiply it by itself. For example, the square of 6 is 36 because 6 × 6 = 36.
But that is not all. A square can also mean an open area in a town or city, such as a public square. As a verb, square can mean to make something even, settle something, or position things at right angles.
In informal English, square can also describe someone who is considered old-fashioned, conventional, or not adventurous. You may also encounter phrases such as square up, square deal, back to square one, and square away.
This guide explains the different meanings of square, including its mathematical definition, slang meaning, common expressions, examples, synonyms, and frequently asked questions.
What Does “Square” Mean?
Square has several major meanings in English.
The most basic meaning is a shape with four equal sides and four right angles.
For example:
“Draw a square on the paper.”
In mathematics, square can mean the result of multiplying a number by itself.
“The square of 7 is 49.”
In everyday English, square can describe something that has a shape similar to a square.
“She bought a square table.”
It can also refer to a public open area:
“We met in the town square.”
And in slang, a square can mean a person who is very conventional or old-fashioned.
Because the word has so many meanings, the surrounding sentence usually tells you which definition is intended.
Square Meaning in Simple English
In simple terms:
Square = a four-equal-sided shape, a number multiplied by itself, or a person/place/action described using the word “square,” depending on context.
What Is a Square in Geometry?
In geometry, a square is a quadrilateral with four equal sides and four right angles.
A square has four important properties:
- It has 4 sides.
- All 4 sides have the same length.
- It has 4 angles.
- Each angle measures 90 degrees.
For example, if every side of a shape measures 5 inches and each corner forms a right angle, the shape is a square.
Square vs. Rectangle
A square is also a special type of rectangle.
Both squares and rectangles have four right angles. However, a rectangle only requires opposite sides to be equal, while a square has all four sides equal.
For example:
- Square: 5 × 5
- Rectangle: 5 × 8
Both have four right angles, but only the first is a square.
Square vs. Rhombus
A rhombus has four equal sides, just like a square.
The difference is that a rhombus does not necessarily have four right angles.
A square has both properties:
Four equal sides + four 90-degree angles = square.
What Does Square Mean in Math?
In mathematics, to square a number means to multiply that number by itself.
For example:
4² = 4 × 4 = 16
Therefore, the square of 4 is 16.
More examples include:
| Number | Calculation | Square |
|---|---|---|
| 2 | 2 × 2 | 4 |
| 3 | 3 × 3 | 9 |
| 4 | 4 × 4 | 16 |
| 5 | 5 × 5 | 25 |
| 6 | 6 × 6 | 36 |
| 7 | 7 × 7 | 49 |
| 8 | 8 × 8 | 64 |
| 9 | 9 × 9 | 81 |
| 10 | 10 × 10 | 100 |
The small raised number ² is called the square exponent.
What Is a Perfect Square?
A perfect square is a number that can be created by multiplying an integer by itself.
Examples include:
- 1
- 4
- 9
- 16
- 25
- 36
- 49
- 64
- 81
- 100
For example:
9 = 3 × 3
So 9 is a perfect square.
What Is the Square Root?
The square root reverses the process of squaring.
For example:
8² = 64
Therefore:
√64 = 8
The square root of a number is a value that produces that number when multiplied by itself.
Square Meaning as a Verb
Square can also be used as a verb.
One meaning is to make something level, even, or aligned.
For example:

This means to make sure the accounts are correct and balanced.
