Pool Cover Size Calculator

Introduction: The Pool Cover Size Calculator is a handy tool designed to help you determine the optimal size for your pool cover. Whether you have a rectangular, circular, or oval-shaped pool, this calculator simplifies the process of finding the right cover dimensions.

Formula: The calculator employs different formulas based on the pool shape. For rectangles, it multiplies the length by the width. For circles, it uses the formula for the area of a circle (π * r^2), where the radius is half of the pool’s length. Oval pool calculations involve the formula for the area of an ellipse (π * a * b), where ‘a’ and ‘b’ are half of the major and minor axes.

How to Use:

  1. Enter the length of your pool in feet.
  2. Input the width of your pool in feet.
  3. Select the shape of your pool from the dropdown menu.
  4. Click the “Calculate” button to get the recommended pool cover size.

Example: Suppose you have a rectangular pool with a length of 20 feet and a width of 10 feet. The calculator would recommend a cover size of 200 square feet.
