Grab your tape measure. You stand ready to tackle home improvement, roofing, landscaping, or shipping. But first, master how to calculate linear feet. This simple length measure-12 inches in a straight line-saves you cash and headaches.
Contractors love it for buying trim, fences, or freight space. Miss it, and you overbuy or run short. Picture ordering 50 feet of baseboard, only to find your room needs 60. Ouch. Let’s fix that with real steps.
What Is Linear Feet in Construction?
Linear feet track straight-line length. Think wall runs or fence lines. No width or height involved just pure distance.
In construction, pros use it daily. A linear feet measurement guide starts here: Measure end-to-end in feet. Done. One linear foot equals one foot. Simple, right?
Humor alert: Unlike square feet (area) or cubic feet (volume), linear feet won’t trick you into buying 3D glasses for a 1D job.
Linear Feet vs Square Feet vs Cubic Feet
Confusion kills projects. Linear feet measure length only. Square feet cover area (length x width). Cubic feet add height for volume.
| Measurement | What It Tracks | Example Use |
|---|---|---|
| Linear Feet | Length (1D) | Baseboards, fences |
| Square Feet | Area (2D) | Flooring, roofs |
| Cubic Feet | Volume (3D) | Shipping boxes |
Linear feet vs square feet: Buy 20 linear feet of 6-inch border? That’s 10 square feet (20 x 0.5). Linear feet vs cubic feet for shipping: Length matters for truck space, volume for weight. Nail these diffs, or waste money.
How to Measure Linear Feet: Basic Steps
Pull out that tape. Stretch it straight along your surface. Record in inches, divide by 12. Boom-linear feet.
For multiple pieces? Add ’em up. Lumber boards? Measure each, sum lengths. Always add 10% waste. Cuts go wrong; life happens.
Pro tip: Convert inches to linear feet easily. 96 inches? 96 ÷ 12 = 8 feet. Logic wins over guesswork.
Linear Feet for Home Improvement Projects
Home renos demand precision. Start with countertops and cabinets.
How to Calculate Linear Feet for Countertops
Measure edge-to-edge along walls. Skip sinks-subtract those inches first. Divide total by 12. A 90-inch run? 7.5 linear feet.
Linear Feet for Kitchen Cabinets
Base cabinets rule. Measure wall segments, exclude appliances. Sum, divide by 12. Industry standard: 10×10 kitchen needs 20 linear feet base.
Do you measure linear feet or square feet for cabinets? Linear only-length along walls. Upper cabinets separate.
| Kitchen Example | Length (Inches) | Linear Feet |
|---|---|---|
| Left Wall | 90 | 7.5 |
| Back Wall | 120 | 10 |
| Island | 48 | 4 |
| Total | – | 21.5 |
Linear Feet for Baseboards and Trim
Perimeter rules. Room 10×12 feet? (10+12) x 2 = 44 linear feet. How to measure linear feet for molding: Same-straight runs, add corners once.
Buy 8-foot pieces? 45 feet needs 6 (round up). Add 10% waste: 45 becomes 49.5 feet.
Linear Feet in Roofing Projects
Roofs mix squares and linear feet. One square = 100 square feet area. Linear feet? Edges and ridges.
How to Calculate Linear Feet for Roofing
Measure roof edges for drip edge. Perimeter in feet. Linear feet of shingles needed: Bundles cover area, not linear.
Linear feet for roof ridge and hips: Measure lengths. One bundle caps 35 linear feet. How to measure linear feet for gutters: Roof perimeter.
Linear feet of fascia and soffit: Same-eaves lengths. Roofing materials calculator in linear feet: Divide square footage by material width.
Linear feet vs roofing squares: Squares for shingles (area), linear for trim. 200 sq ft roof? 2 squares, but edges might hit 67 linear feet at 3-ft width.
Linear Feet for Landscaping
Yards transform with fences and edges. Perimeter math shines.
How to Calculate Linear Feet for Fencing
Linear feet for chain link fence / wood fence / vinyl fence: Sum sides. 20×30 garden? 100 linear feet (20+30+20+30).
Gates? Add their width once.
Linear Feet for Garden Edging and More
Garden bed? Circumference for curves: π x diameter. 10-ft diameter? 31.4 feet.
Linear feet for retaining wall blocks: Perimeter blocks follow. Landscape lighting linear feet: Wire or fixture runs. Linear feet for drip irrigation lines: Path lengths.
Add 10-20% extra. Obstacles eat material.
Linear Feet in Shipping and Moving
Freight pros charge by linear feet in trailers. What is linear feet in trucking? Straight-line space used.
How to Calculate Linear Feet for Shipping
Linear feet for freight pallets: Pallets ÷ 2 x length (inches) ÷ 12. Two 48-inch pallets? 8 feet.
Linear feet in LTL freight: Under 12 feet standard, 750 cubic feet max. Over 10 feet? 1000 lbs per foot rate.
How to calculate linear feet of cargo in trailer: Sum pallet lines. Linear feet for moving truck space: Sofa + boxes stack lengthwise. 2-bedroom? 10-15 feet.
Storage unit linear feet vs square feet: 10×10 unit = 10 linear feet wall space, 100 sq ft floor. Linear feet vs cubic feet for shipping: Linear for space, cubic for volume.
Convert Room Measurements to Linear Feet
How many linear feet are in a 10×10 room? Perimeter: 40 feet ((10+10)x2). Not 100—that’s square feet.
Convert room measurements to linear feet: Length + width, x2. How to convert square feet to linear feet of material: Need width. Sq ft ÷ width (ft).
Linear Feet Calculators and Tools
Skip math errors. Use a linear feet calculator. Input lengths, get totals. Roofing? Try material-specific ones.
Online gems handle waste auto. Pros: Fast. Cons: Double-check inputs.
Common Mistakes When Calculating Linear Feet
Rookies trip here. Common mistakes when calculating linear feet: Mix units (linear vs square). Forget waste—add how much extra linear feet to add for waste: 10-20%.
Curves? Measure actual path. Round wrong? Carry decimals. How to convert inches to linear feet: ÷12 precisely.
Laugh it off: One guy bought square footage for fence posts. Neighbors chuckled.
