Use our Square Calculator to instantly determine the area, perimeter, and diagonal of any square. Simply input the side length to get precise geometric calculations. Ideal for students, designers, and construction planning.

Formula:

The formulas used for calculating the properties of a square are:

  • Area (A): A = s²
  • Perimeter (P): P = 4s
  • Diagonal (d): d = s√2

Where:
A = Area
P = Perimeter
d = Diagonal
s = Side Length
