🪵 Wainscoting Calculator
Calculate wainscoting boards and panels needed for your room
How to Use This Calculator
Enter Room Dimensions
Input the length and width of your room in feet. Measure the room where you'll be installing wainscoting on all walls.
Specify Wainscoting Height
Select wainscoting height in inches. Standard is 36 inches (chair rail height), but wainscoting can range from 24 to 42 inches depending on room height and style preference.
Set Board Width and Panel Spacing
Select board width (standard is 8 inches) and panel spacing (standard is 4 feet). Wainscoting uses vertical boards with panels between them. Closer spacing uses more panels.
Calculate and Order
Click "Calculate Wainscoting" to see boards needed, wainscoting area, and linear feet. Add 10% extra for waste. Order boards and panels from lumber suppliers or home improvement stores.
Formula
Perimeter (ft) = 2 × (Length + Width)
Wainscoting Area (sq ft) = Perimeter (ft) × Height (inches) ÷ 12
Number of Panels = Perimeter (inches) ÷ Panel Spacing (feet × 12)
Boards Needed = Wainscoting Area ÷ (Board Width × Height)
Example 1: Standard Room (20 ft × 15 ft, 36" height, 8" boards, 4 ft spacing)
Step 1: Calculate perimeter: 2 × (20 + 15) = 70 feet
Step 2: Calculate wainscoting area: 70 × 36 ÷ 12 = 210 sq ft
Step 3: Convert perimeter: 70 ft = 840 inches
Step 4: Calculate panels: 840 ÷ (4 × 12) = 840 ÷ 48 = 17.5 → 18 panels
Step 5: Calculate boards: 210 ÷ ((8/12) × (36/12)) = 210 ÷ 2 = 105 boards
Step 6: Add waste: 105 × 1.10 = 116 boards (with 10% waste)
Example 2: Larger Room (30 ft × 20 ft, 32" height, 6" boards, 4 ft spacing)
Step 1: Calculate perimeter: 2 × (30 + 20) = 100 feet
Step 2: Calculate wainscoting area: 100 × 32 ÷ 12 = 266.7 sq ft
Step 3: Convert perimeter: 100 ft = 1,200 inches
Step 4: Calculate panels: 1,200 ÷ 48 = 25 panels
Step 5: Calculate boards: 266.7 ÷ ((6/12) × (32/12)) = 266.7 ÷ 1.33 = 200 boards

Common Applications
Interior Renovation: Homeowners and contractors planning interior room renovations use this calculator to order the correct quantity of wainscoting boards and panels. Standard wainscoting uses 36-inch height with 8-inch boards at 4-foot spacing, which this calculator helps determine accurately.
Bathroom Remodeling: Contractors and homeowners planning bathroom wainscoting use this tool to estimate materials needed. Bathroom wainscoting typically uses similar dimensions to other rooms but may require water-resistant materials.
Formal Room Design: Designers and contractors planning formal dining rooms or living rooms use this calculator to determine wainscoting quantities needed, ensuring sufficient materials are on-site before starting work.
Tips for Best Results
- Wainscoting Height: Standard is 36 inches (chair rail height); ranges from 24-42 inches based on room height
- Board Widths: Standard is 8 inches; wider boards (10-12") use fewer pieces but cost more
- Panel Spacing: Standard is 4 feet; closer spacing (3 ft) uses more panels, wider (5 ft) uses fewer
- Add Waste: Always add 10% extra for waste, cuts around doors and windows, and mistakes
- Order Together: Order all boards from the same batch for color consistency
Frequently Asked Questions
How many wainscoting boards do I need for a 20×15 foot room?
For a 20×15 foot room with 36-inch wainscoting height, 8-inch boards, and 4-foot panel spacing, you'll need approximately 116 boards (with 10% waste). The wainscoting area is 210 sq ft, and the room perimeter is 70 feet. Always add 10% extra for waste.
What is wainscoting?
Wainscoting is a decorative wall treatment that covers the lower portion of interior walls, typically extending 24-42 inches from the floor. It consists of vertical boards (stiles) and panels, often topped with a chair rail molding, creating an elegant, traditional appearance.
What height should wainscoting be?
Standard wainscoting height is 36 inches (3 feet), which matches typical chair rail height. Wainscoting can range from 24 inches (2/3 wall) to 42 inches (tall) depending on room height, ceiling height, and design preference. Choose based on room proportions and style.
Do I need to add extra boards for waste?
Yes! Always add 10% extra for waste, cuts around doors and windows, and mistakes during installation. If you need 105 boards, order about 116 boards (with 10% waste) to ensure you have enough material.
What size boards should I use for wainscoting?
Standard wainscoting board width is 8 inches, creating a balanced appearance. Wider boards (10-12 inches) use fewer pieces but cost more. Narrower boards (4-6 inches) use more pieces but may look busy. Choose based on appearance preference and budget.
Can I install wainscoting myself?
Yes! Wainscoting is a popular DIY project. It requires measuring, cutting, and installing boards and panels. Use a level, miter saw for cuts, and proper adhesive or fasteners. Start with a single wall to practice before tackling the entire room.
