When installing vertical cladding (like wood, vinyl, or metal panels), accurate measurements are crucial to avoid material shortages or excess waste. This guide explains the formulas used in our Vertical Cladding Calculator and provides real-world examples.

1. Total Wall Area Calculation

First, calculate the total wall area before accounting for openings (doors/windows).

Formula:

$\text{Total Wall Area} = \text{Wall Length} \times \text{Wall Height} \times \text{Number of Walls}$

Example:

Wall Length: 20 ft
Wall Height: 10 ft
Number of Walls: 2

2. Deducting Openings (Doors & Windows)

Subtract the area of doors and windows to get the net wall area.

Formula:

$\text{Net Wall Area} = \text{Total Wall Area} - (\text{Number of Doors} \times \text{Door Area}) - (\text{Number of Windows} \times \text{Window Area})$

Example:

Total Wall Area: 400 ft²
Doors: 2 doors × 21 ft² each = 42 ft²
Windows: 3 windows × 12 ft² each = 36 ft²

400−42−36=322 ft²

3. Calculating Vertical Panels Needed

Determine how many cladding panels are required based on panel dimensions.

Formula:

$\text{Panels per Row} = \left\lceil \frac{\text{Wall Length}}{\text{Panel Width}} \right\rceil$

$\text{Rows per Wall} = \left\lceil \frac{\text{Wall Height}}{\text{Panel Height}} \right\rceil$

$\text{Total Panels} = \text{Panels per Row} \times \text{Rows per Wall} \times \text{Number of Walls}$

Example:

Wall Length: 20 ft
Panel Width: 6 inches (0.5 ft)
Wall Height: 10 ft
Panel Height: 8 ft
Number of Walls: 2

$\text{Panels per Row} =\left\lceil\frac{20}{0.5}\right\rceil=40\text{ panels}$

$\text{Rows per Wall} =\left\lceil\frac{10}{8}\right\rceil=2\text{ rows}$

$\text{Total Panels} =40\times 2\times 2=160\text{ panels}$

4. Adding Wastage (%)

Material wastage (due to cuts, errors, or defects) should be factored in.

Formula:

$\text{Total Cladding Area} = \text{Net Wall Area} \times \left(1 + \frac{\text{Wastage \%}}{100}\right)$

Example:

Net Wall Area: 322 ft²
Wastage: 10%

$322\times(1+0.10)=354.2\,\text{ft}^2$

Real-World Example

Scenario:

Wall Dimensions: 15 ft (length) × 12 ft (height), 2 walls
Openings: 1 door (21 ft²), 2 windows (12 ft² each)
Cladding Panels: 5 inches wide × 6 ft tall
Wastage: 15%

Calculations:

Total Wall Area:

15×12×2=360 ft²

Net Wall Area:

360−21−(2×12)=315 ft²

Panels Needed:

Panels per Row:

$\left\lceil \frac{15\ \text{ft}}{0.4167\ \text{ft}} \right\rceil = 36\ \text{panels} \quad (5\ \text{inches} = 0.4167\ \text{ft})$

Rows per Wall:

$\left\lceil \frac{12\ \text{ft}}{6\ \text{ft}} \right\rceil = 2\ \text{rows}$

Total Panels:

$36 \times 2 \times 2 = 144\ \text{panels}$

Total Cladding (with wastage):

$315\ \text{ft}^2 \times 1.15 = 362.25\ \text{ft}^2$

Final Estimate:

Panels Required: 144 panels
Total Cladding Area Needed: 362.25 ft²
