Measurements

Use project and product-specific inputs

  1. Measure the clear run and actual picket width, then enter the allowed maximum gap.
  2. Choose Imperial or Metric and keep every measurement in the selected unit system.
  3. Use package capacity and price only from the exact product or supplier.

Method

How the estimate is calculated

The engine chooses a whole picket count and distributes remaining clear space equally.

  • Required quantity remains separate from rounded purchase quantity.
  • No hidden waste, yield, density, spacing, or price is applied.
  • The TypeScript Calculator Core is the only executable formula source.

Before buying

Verify the result

Check current manufacturer instructions, design documents, site conditions, supplier units, and local requirements.

  • Re-measure critical dimensions.
  • Confirm product coverage or yield.
  • Keep a record of the assumptions shown with the result.
