2. Defining Linear Feet: A One-Dimensional Measurement
2.1. What is a Linear Foot?
A linear foot is a unit of measurement representing length in one dimension. Imagine a straight line exactly 12 inches (or approximately 30.48 centimeters) long. This line is a linear foot. It’s a fundamental unit used to measure the length of items like lumber, trim, fabric, fencing, and piping. Unlike area or volume measurements, linear feet focus solely on length, disregarding width or height.
2.2. Common Applications of Linear Feet
Linear feet are commonly used across various industries and everyday scenarios. Here are a few examples:
- Lumber: When purchasing wood for construction or woodworking projects, lumber is often sold by the linear foot.
- Fabric: Fabric stores typically sell materials like cloth, ribbon, and trim by the linear foot or yard (which is three linear feet).
- Fencing: Fencing materials, such as posts and rails, are often priced and sold by the linear foot.
- Piping: Plumbers and contractors use linear feet to measure and purchase pipes for plumbing systems.
- Baseboards and Molding: These decorative elements are also measured and sold by the linear foot to fit along walls and ceilings.
- Cabling and Wiring: Electricians use linear feet to measure and purchase electrical cables and wiring for installations.
- Landscaping Edging: Materials used to create borders in gardens and lawns are sold by the linear foot.
2.3. How to Calculate Linear Feet
Calculating linear feet is straightforward. You simply measure the length of the item in question. If you’re measuring multiple items of the same length, you can add their individual lengths to find the total linear feet.
Example:
Let’s say you need to purchase trim for a window. You measure each side of the window and find the following lengths:
- Top: 3 feet
- Bottom: 3 feet
- Left side: 2 feet
- Right side: 2 feet
To find the total linear feet of trim needed, you would add these measurements together:
3 feet + 3 feet + 2 feet + 2 feet = 10 linear feet
Therefore, you would need to purchase 10 linear feet of trim.
2.4. The Importance of Accurate Linear Foot Measurement

- Perimeter = 2 x (50 feet + 30 feet)
- Perimeter = 2 x 80 feet
- Perimeter = 160 linear feet
You will need 160 linear feet of fencing material.
-
Square Feet: If you also want to calculate the area of your yard for landscaping purposes:
- Area = Length x Width
- Area = 50 feet x 30 feet
- Area = 1500 square feet
Your yard has an area of 1500 square feet.
5.2. Flooring Project
Scenario: You want to install new hardwood flooring in your living room. The room is rectangular, measuring 15 feet long and 12 feet wide.
Calculations:
-
Square Feet: To determine the amount of flooring material needed, you need to calculate the area of your living room.
- Area = Length x Width
- Area = 15 feet x 12 feet
- Area = 180 square feet
You will need to purchase at least 180 square feet of hardwood flooring. It’s always wise to add an extra 10% for waste and cuts, so you should consider buying around 198 square feet.
-
Linear Feet: You also want to install baseboards around the perimeter of the room.
- Perimeter = 2 x (Length + Width)
- Perimeter = 2 x (15 feet + 12 feet)
- Perimeter = 2 x 27 feet
- Perimeter = 54 linear feet
You will need 54 linear feet of baseboards.
5.3. Painting Project
Scenario: You want to paint the walls of your bedroom. The room is 10 feet long, 12 feet wide, and 8 feet high.
Calculations:
-
Square Feet: To determine the amount of paint needed, you need to calculate the surface area of the walls. Assuming there are no windows or doors, the calculation is as follows:
- Area of two longer walls = 2 x (Length x Height) = 2 x (10 feet x 8 feet) = 160 square feet
- Area of two shorter walls = 2 x (Width x Height) = 2 x (12 feet x 8 feet) = 192 square feet
- Total wall area = 160 square feet + 192 square feet = 352 square feet
You will need to purchase enough paint to cover 352 square feet.
Note: This calculation does not account for windows and doors.
