Formula Used by the Calculator

The calculator uses a simple area formula.

Single Board Formula

Square Feet = (Width × Length) ÷ 12

Where:

• Width = inches
• Length = feet

---

Example

Width = 12 inches

Length = 10 feet

Square Feet = (12 × 10) ÷ 12

Square Feet = 10 sq ft

---

Multiple Board Formula

Total Square Feet = Square Feet Per Board × Number of Boards

---

Example

Square Feet Per Board = 10

Quantity = 25

Total Square Feet = 10 × 25

Total Square Feet = 250 sq ft

---

Practical Example 1: Building a Wooden Deck

Imagine you're constructing a backyard deck.

Each deck board measures:

• Width = 6 inches
• Length = 12 feet

You need:

• 40 boards

Using the calculator:

Per Board

(6 × 12) ÷ 12 = 6 sq ft

Total Coverage

6 × 40 = 240 sq ft

This allows you to estimate deck coverage accurately before purchasing lumber.

---

Practical Example 2: Flooring Installation

Suppose you're installing wood flooring in a room.

Each plank measures:

• Width = 8 inches
• Length = 8 feet

You purchase:

• 60 planks

Calculation:

Per Board

(8 × 8) ÷ 12 = 5.33 sq ft

Total Coverage

5.33 × 60 = 319.8 sq ft

This helps determine whether the flooring material is sufficient for the room.
