Linear Feet Calculator — Calculate Length and Measurements

Linear Feet Calculator

Calculate linear feet for any project. Convert between linear feet, inches, yards, meters, and centimeters for flooring, fencing, lumber, and more.

Step 1: Measurements

20.0
12.0

Linear Feet Formula

Linear Feet = Length (ft) × Quantity
Linear Inches = Length (ft) × 12 × Quantity
Square Feet = (Length × Width/12) × Quantity

Step 2: Project Type & Options

Common Project Lengths

Room perimeter: 40-60 linear ft
Fence section: 100-200 linear ft
Deck boards: 150-300 linear ft
Baseboards: 50-100 linear ft
Piping: 20-50 linear ft

Linear Feet Formulas

Linear Feet = Length (ft) × Quantity

Where:
• Length = Measurement in feet
• Quantity = Number of pieces/items

Conversions:
• Inches = Linear Feet × 12
• Yards = Linear Feet ÷ 3
• Meters = Linear Feet × 0.3048
• Centimeters = Linear Feet × 30.48
• Square Feet = Linear Feet × (Width in inches ÷ 12)

Example Calculation

Example: Flooring for a Room

Length: 15 feet
Width: 3 inches per board
Quantity: 20 boards

Calculation:
Linear Feet = 15 ft × 20 = 300 linear ft
Linear Inches = 300 × 12 = 3600 inches
Square Feet = 300 × (3 ÷ 12) = 75 ft²

Converted:
300 linear ft = 100 yards = 91.4 meters
