Linear Footage Calculator: How to Measure and Price Any Run

A homeowner once asked me why her fence bid was $1,800 higher than the guy down the street. Same yard. Same wood. The other guy measured the front run and quoted off that, then “estimated” the rest. I walked the whole property line with a wheel. He missed 64 feet. That gap is the difference between a profit and a callback you eat.

Linear footage is the backbone of contractor pricing for anything that runs in a line. Fence, baseboard, crown, gutters, trim, retaining wall, pipe. Get the number wrong and every dollar after it is wrong too.

Quick Answer: What Is Linear Footage?

Linear footage is the total length of a material measured in a straight line, in feet, ignoring width and thickness. A linear foot is just one foot of length. To find linear footage, measure each straight section of the run, then add the sections together. A 12-foot wall plus an 8-foot wall is 20 linear feet of baseboard. Width does not matter. Only the run.

Linear Feet vs Square Feet vs Board Feet

This trips up new estimators more than anything else. Three different units, three different jobs. Mix them up and your bid is garbage.

Unit	What it measures	Use it for
Linear foot	Length only (1 ft of run)	Fence, trim, gutters, baseboard, pipe, crown
Square foot	Area (length x width)	Flooring, drywall, paint, roofing, tile
Board foot	Volume (length x width x thickness)	Rough lumber, hardwood pricing

Here is the simple rule I give every new hand. If the material comes in a long strip and you install it end to end, price it by the linear foot. If it covers a surface, price it by the square foot. If you buy raw lumber by the bundle, you are probably dealing with board feet. Want the lumber side of this? Our Board Foot Calculator handles that math, and the Square Footage Calculator covers area jobs.

One trap worth calling out: countertops. People measure them in linear feet of cabinet run, but fabricators price slabs by the square foot. A 20-foot kitchen run can be 50 square feet of stone. Never quote a stone top off linear feet alone.

How to Calculate Linear Footage in 4 Steps

1. Break the run into straight sections. Every corner ends one section and starts another. An L-shaped deck rail is two runs, not one.
2. Measure each section in feet. Use a wheel for long outdoor runs and a tape for interior trim. Round up to the next foot.
3. Add the sections together. That sum is your total linear footage before waste.
4. Add a waste factor. Cuts, miters, and damaged stock eat material. I add 10% on straight runs and 15% on anything with lots of corners or angles.

That waste factor is not padding. It is field reality. Every miter cut on crown molding burns a few inches, and a 45-degree corner can waste a foot of stock per joint. Skip the waste factor and you are making a second material run on your own dime.

Worked Example 1: Fencing a Backyard

Say the yard is a rectangle, 60 feet by 90 feet, but the house covers one 30-foot stretch. Here is the math.

• Two long sides: 90 + 90 = 180 ft
• Two short sides: 60 + 60 = 120 ft
• Subtract the house wall: 120 + 180 - 30 = 270 linear feet of fence

At a typical installed rate of $28 per linear foot for wood privacy fence, that is 270 x $28 = $7,560 before extras. Add a gate at around $300 and you are near $7,860. Notice how one missed wall, like that 30-foot stretch, swings the number by over $800. Measure the whole perimeter every time.

The breakdown chart above shows how a smaller 150-foot job stacks up once you include removal and a gate.

Worked Example 2: Gutters on a Ranch

Gutters run the eave line, so you measure the horizontal length of each roof edge, not the slope. A simple ranch with two long eaves at 48 feet each gives you 96 linear feet.

At $10 per linear foot for aluminum K-style gutters, that run costs 96 x $10 = $960. Switch to copper at $30 per linear foot and the same run jumps to $2,880. Same length. Wildly different price. This is why nailing the linear footage first matters more than the material choice. The length drives everything. Our Gutter Installation Cost Calculator runs these numbers for you.

Cost Per Linear Foot: 2026 Ranges

These are installed ranges I see in the field and that track with Angi and HomeGuide cost data (2026). The wage figures behind the labor numbers line up with BLS construction wage data. Prices vary by region, material grade, and site access, so always get local quotes and price your own market.

Material	Cost per linear foot (installed)
Chain link fence	$10 - $30
Wood privacy fence	$15 - $45
Vinyl fence	$20 - $50
Vinyl gutters	$4 - $9
Aluminum K-style gutters	$7 - $14
Copper gutters	$20 - $45
Fence removal (old)	$3 - $9

Labor alone on a fence runs $5 to $20 per linear foot depending on terrain, post depth, and how many corners you fight. Rocky soil and slopes push you to the top of that range fast.

Where Contractors Lose Money on Linear Math

• Measuring one side and doubling it. Yards are rarely symmetrical. Walk the whole run.
• Forgetting the waste factor. A 10% to 15% buffer covers cuts and miters. I have eaten the cost of a second material run for skipping it.
• Quoting stone tops off linear feet. Slabs price by the square foot. Convert before you bid.
• Ignoring corners and gates. Each corner post and each gate adds labor and hardware that a flat per-foot rate misses.
• Pricing slope length on gutters. Gutters follow the level eave, not the roof pitch. Measuring the slope inflates your number.

Measure twice, cut once. That goes for bids too. I have lost more sleep over a sloppy takeoff than over any actual cut on the saw.

How This Fits Your Whole Bid

Linear footage is step one. After that you layer in material grade, labor rate, waste, overhead, and profit. A clean run measurement feeds straight into a quantity takeoff, and the takeoff feeds the estimate. Get the foundation number right and the rest of the bid holds together. Get it wrong and every markup just multiplies the mistake.

Based on field experience over 20 years of takeoffs, the contractors who win consistently are not the fastest measurers. They are the most accurate ones. Speed without accuracy is just a faster way to lose money.

Frequently Asked Questions

How do I calculate linear footage for trim or baseboard? Measure the length of each wall in feet at floor level, skip doorways wider than the casing, and add the wall lengths together. Add 10% for miter cuts. For a 12 by 14 room that is roughly 52 linear feet before waste, about 57 with the buffer.

Is a linear foot the same as a regular foot? Yes. A linear foot and a foot are the same 12-inch length. The word “linear” just signals you are measuring straight-line length, not area or volume. People say it to be clear they are not talking square feet.

How do contractors price a fence per linear foot? Most contractors set a per-foot installed rate that bundles material, labor, and a small markup, then multiply by the total run and add gates, corners, and removal. Wood privacy fence commonly lands at $15 to $45 per foot installed in 2026. To build a full fence bid in minutes, run it through our Linear Footage Calculator and drop the total into your estimate.

How much waste should I add to a linear footage estimate? Add 10% on straight runs and 15% on jobs with lots of corners, angles, or miters. Crown molding and decorative trim run higher because every joint wastes stock. The buffer covers cuts, damaged pieces, and the inevitable measuring slip.

How do I convert linear feet to square feet? You cannot convert directly without the width. Multiply linear feet by the material width in feet to get square feet. A 100-foot run of 0.5-foot-wide trim covers 50 square feet. Length alone is not enough for area materials.

Contractors who switched to EstimationPro report cutting estimate time from a couple hours down to minutes per bid, and the math is done for them so a missed wall does not blow up the job. EstimationPro does not just total your linear footage. It builds the full estimate, sends the proposal automatically, follows up with the homeowner so you win more of the bids you already send, and invoices when the job is done.
