This square calculator calculates the perimeter, area and diagonal of a square by taking account of its side length.

Side length:

What is a square?

A square is a plane figure with four equal straight sides and four right angles. The algorithm behind this square calculator applies the formulas given below that all use the square’s side length:

  • Square Perimeter Formula = Side length * 4.
  • Square Area Formula = Side length^2.
  • Square Diagonal Formula = (Square root of 2) * Side length.

Example of a result

Assuming we have a square with a side of 2 feet we will obtain the following results:

Perimeter = 8

Area = 4

Diagonal = 2.83
