Perimeter Calculator
Calculate the perimeter or circumference of various 2D shapes with interactive 3D visualizations.
Square Calculation
Perimeter = 4a
Calculation Details
- Square: All 4 sides are equal, so simply multiply the side length by 4.
Measurement Units
The perimeter is expressed in linear units. For example, if you input dimensions in centimeters, the result will be in cm.
