Valley Rafter Calculator

The Valley Rafter Calculator is a tool designed to determine the length of a valley rafter—a diagonal rafter in a roof structure—based on specific measurements. The formula used in the calculator is:

Formula

Length of Valley Rafter = √(Run² + (0.5 * Width)²)

Where:

  • Run represents the horizontal distance, calculated as a key input.
  • Width denotes the width of the building at the eaves, another essential parameter for accurate calculation.

This straightforward formula allows for precise determination of the valley rafter length, contributing significantly to construction planning and execution.
