Parallelogram Area and Perimeter Calculator

Enter the base, height and slanted side length of a parallelogram to calculate its area and perimeter.

Parallelogram Area and Perimeter Calculator

Calculate the area and perimeter of a parallelogram from its base, height and side length.

This calculator provides an estimate for general informational purposes only. It is not a substitute for professional financial, mechanical or engineering advice.

A parallelogram's area uses its base and perpendicular height (not the slanted side), while its perimeter adds up both pairs of equal sides.

Example

  • With the default values shown above, this calculator returns: Area ≈ 60.00; Perimeter ≈ 38.00.

Frequently Asked Questions

What are the formulas?

Area = Base × Height (perpendicular height, not the slanted side). Perimeter = 2 × (Base + Side).

What's the difference between height and slanted side?

Height is the perpendicular (straight up-and-down) distance between the two parallel bases, while the slanted side is the actual length of the angled side — they're only equal in a rectangle.
