Shiplap Material Estimator Tool

Master Your Shiplap Project with Our Free Online Calculator

Have you envisioned transforming your interior with shiplap but feel unsure where to begin? Our comprehensive shiplap material estimator is designed to guide you seamlessly through every phase of your project. Embarking on a DIY shiplap wall installation can raise numerous questions: What quantity of boards is required? How do you accurately calculate the needed materials and overall project cost? This free online calculator serves as your ultimate tool, providing clear answers and detailed estimations for coverage, board count, and total expenses. Let's get started.

Understanding Shiplap Paneling

Shiplap is a robust form of paneling, originally developed for exterior siding but now a popular interior design choice. It can be crafted from traditional wood or modern materials like PVC. Its defining characteristic is the rabbet joint—a connectable groove system that allows boards to overlap, creating a tight and secure seal. This versatile material complements a wide range of styles, from modern and industrial to classic farmhouse. Shiplap boards can be painted or stained and installed in horizontal, vertical, or even diagonal patterns. While planning your project, consider using a paint calculator to estimate finishing needs. First, let's explore how to utilize our scientific calculator to determine your precise material requirements.

How to Use the Shiplap Calculator: A Step-by-Step Guide

Our free calculator simplifies the process of estimating shiplap needs and costs. Follow this straightforward guide for accurate results.

1. Define Your Project Area: Begin by selecting your project type: a simple flat wall, a wall with windows and/or doors, or a ceiling. For a basic wall, input the height and length to automatically calculate the area. For walls with openings, input the wall dimensions and then add the number, height, and width of each window and door. The tool will deduct these from the total area.
2. Specify Shiplap Board Size: Enter the width and length of a single shiplap board. The calculator will determine the area each board covers.
3. Calculate Board Quantity: Instantly, the tool computes the number of shiplap boards needed per square foot and the total required for your entire project. We recommend adding a waste factor (default is 5%) to account for cuts, breakage, or errors; this adjustable feature ensures you purchase sufficient material.
4. Estimate Project Costs: Expand the "Calculate costs" section to use the tool as a shiplap cost calculator. Input the price per board and the installation cost per square foot (typically $4, varying by location). The free calculator will then provide a total estimated expense, inclusive of materials (with waste) and professional installation.

Practical Example: Calculating Boards for a Living Room Wall

You've decided to install shiplap on a living room wall. The wall is 8 feet high and 16 feet long, featuring two windows each measuring 3 feet high by 2 feet wide.

Step 1: Calculate Project Area

First, find the net wall area:

(8 ft × 16 ft) - 2(3 ft × 2 ft) = 128 sq ft - 12 sq ft = 116 sq ft.

Step 2: Determine Board Coverage

Assume a board is 8 inches wide (0.667 ft) and 8 feet long. Its area is:

0.667 ft × 8 ft = 5.336 sq ft per board.

Boards per square foot:

1 / 5.336 ≈ 0.1875 boards per sq ft.

Step 3: Find Total Boards Needed

0.1875 boards/sq ft × 116 sq ft = 21.75 boards.

Round up to 22 boards.

Step 4: Calculate Project Cost

If boards cost $5 each and installation is $4 per sq ft:

Material Cost = 22 boards × $5 = $110
Installation Cost = 116 sq ft × $4 = $464
Total Estimated Cost = $110 + $464 = $574

Shiplap Material Costs and Selection

Choosing the right shiplap material is crucial for both aesthetics and budget. Prices vary significantly based on material type. Below is a general cost guide per square foot, excluding installation:

• Hardwood Boards: Approximately $6 - $11 per sq ft.
• Cedar Boards: Approximately $5 - $8 per sq ft.
• Pine Boards: Approximately $3 - $7 per sq ft.
• Plywood Boards: Approximately $2 - $3 per sq ft.
• MDF (Medium-Density Fibreboard): Approximately $2 - $10 per sq ft.
• PVC Boards: Approximately $3 - $5 per sq ft.

Standard shiplap widths are often 5 1/4 or 7 1/4 inches, available in various lengths and thicknesses. Generally, thicker and longer boards command a higher price. The final project cost is influenced by the siding material, total project size, and local contractor rates.

Shiplap Installation Overview

Ready for installation? The process differs between materials. PVC paneling is relatively simple, often involving adhesion to a clean, dry wall. Wood shiplap installation is more involved:

1. Surface Preparation: Ensure the wall or ceiling is perfectly clean, dry, level, and free of dust.
2. Install Cleats: Attach wooden cleats to the wall, perpendicular to the direction your boards will run, to create a framing structure.
3. Attach Boards: Nail the first board at the bottom of the surface. Continue installing subsequent boards, interlocking them via their rabbet joints.
4. Make Necessary Cuts: Use a jigsaw to cut boards for corners, obstacles like outlets, or to fit the final space.
5. Finishing: Once installed, you can paint, stain, and enjoy your new accent wall or ceiling.
