How to Use the Shiplap Calculator

The Shiplap Calculator is a practical tool that allows you to calculate the amount of shiplap needed for your project. Shiplap is a popular choice for wall paneling and siding, and accurately estimating the required quantity ensures a smooth and efficient installation process. In this article, we will guide you through the process of utilizing the Shiplap Calculator effectively.

Instructions for Utilizing the Calculator

Follow these steps to use the Shiplap Calculator:

  • Wall Width: Enter the width of the wall in feet. This represents the horizontal measurement of the area you plan to cover with shiplap.
  • Wall Height: Specify the height of the wall in feet. This indicates the vertical measurement of the area you intend to panel with shiplap.
  • Shiplap Coverage: Provide the coverage per board in square feet. This value represents the area covered by each individual shiplap board.
  • Overlap Percentage: Indicate the overlap percentage as a decimal or fraction. This accounts for the overlap of each board to ensure a secure and visually appealing installation.
  • Waste Percentage: Enter the waste percentage as a decimal or fraction. This considers any material waste resulting from cutting and fitting shiplap boards.

Once you have filled in all the required fields, click the Calculate button.

Shiplap Calculator Formula

The Shiplap Calculator utilizes the following formula to determine the total shiplap needed:

Total Shiplap Needed = (Wall Width * Wall Height) / (Shiplap Coverage * (1 - Overlap Percentage)) * (1 + Waste Percentage)

The formula calculates the total area of the wall and divides it by the effective area covered by each shiplap board, considering the overlap percentage. The result is then adjusted to account for any waste resulting from cutting and fitting.

Illustrative Example

Let's consider an example to demonstrate how the Shiplap Calculator works:

Suppose you have a wall with a width of 10 feet and a height of 8 feet. The shiplap boards you are using have a coverage of 5 square feet per board. You plan to overlap the boards by 10% (0.1), and you anticipate 5% (0.05) waste due to cutting and fitting.

By inputting these values into the Shiplap Calculator, you will obtain the following results:

  • Wall Width: 10 feet
  • Wall Height: 8 feet
  • Shiplap Coverage: 5 square feet per board
  • Overlap Percentage: 10%
  • Waste Percentage: 5%
  • Total Shiplap Needed: 12 boards

Based on this example, the calculated total shiplap needed for your project is 12 boards.

Illustrative Table Example

Here's a table showcasing multiple rows of example data:

Wall Width (ft)

Wall Height (ft)

Shiplap Coverage (sq. ft per board)

Overlap Percentage

Waste Percentage

Total Shiplap Needed (boards)


Please note that the values in this table are for illustrative purposes only and may not represent real-world data.

The Shiplap Calculator is an invaluable tool for accurately estimating the amount of shiplap needed for your project. By providing the wall dimensions, shiplap coverage, overlap percentage, and waste percentage, you can ensure that you purchase the correct quantity of shiplap boards, minimizing material waste and facilitating a successful installation. Enhance your project planning and achieve professional results with the Shiplap Calculator.
