Sidewalk Square Footage Calculator
Measure any sidewalk or walkway from satellite imagery — straight runs, curved garden paths, or a whole storefront frontage — without a tape measure or site visit.
Sidewalk square footage is length × width. A 60 ft run at 5 ft wide is 300 square feet. Enter your dimensions below for an instant number, or trace the real walkway on satellite imagery when it curves, changes width, or wraps a building.

Free, no sign-up. Add a run for each stretch of walkway — the front walk, the side path, the landing — then subtract any driveway crossing that belongs to a different line item.
Sidewalk run
Subtract: Driveway crossing
Where a driveway crosses the walk, that section is usually the driveway apron and gets measured with the driveway. Leave this at zero if you're washing the whole frontage at one rate.

Length × width only works on straight, rectangular sections. For curves, freeform shapes, or edges you can't easily reach with a tape, trace the real shape on satellite imagery and let the area calculate itself.
How do you calculate sidewalk square footage?
Multiply the length of the run by its width, and add the runs together. A 60 ft sidewalk at 5 ft wide is 300 square feet. Residential front walks are typically 3–4 ft wide, public sidewalks 4–6 ft, and commercial storefront walkways 6–12 ft. For curved paths or walks that change width, trace the outline on satellite imagery instead — SurfaceMeasure returns the area directly, typically within 1–3% of a tape measurement.
How to Calculate Sidewalk Square Footage
Sidewalks are the simplest surface on the property to calculate and the easiest to get wrong, because the width is small enough that a rough guess turns into a big percentage error. Everything below assumes you measured the width rather than assumed it.
The width is where the error lives. Length is easy to pace or read off imagery; width is four or five feet of concrete that people routinely eyeball. Get it wrong by a foot on a 4 ft walk and the whole estimate is off by 25%. When you trace on satellite, zoom fully in before placing points along the edges.
Measuring the driveway in the same visit? The driveway square footage calculator handles the main surface, and the patio calculator covers the back of the property — most jobs are all three at once.
Standard Sidewalk Widths and Sizes
Residential front walks are usually 3–4 ft wide, public sidewalks 4–6 ft, and commercial storefront walkways 6–12 ft. ADA accessible routes require a minimum 36-inch clear width, which is much of why 4 ft became the practical build standard. Use these as a sanity check — then measure the actual walk.
| Walkway | Typical size | Approx. area |
|---|---|---|
| Front walk to the door3.5 × 25 ft | 3.5 × 25 ft | ≈ 88 sq ft |
| Side path to a gate3 × 40 ft | 3 × 40 ft | 120 sq ft |
| City sidewalk across a lot5 × 60 ft | 5 × 60 ft | 300 sq ft |
| Single storefront walkway8 × 30 ft | 8 × 30 ft | 240 sq ft |
| Strip center frontage12 × 300 ft | 12 × 300 ft | 3,600 sq ft |
| Walkway around a buildingvaries | varies | 500–1,500 sq ft |
Local codes, lot frontage, and building setbacks all move these. Municipal specifications vary — check with the jurisdiction where a walk is being built or replaced rather than cleaned.
What Sidewalk Cleaning Costs Per Square Foot
Sidewalks price like the flatwork they are. Concrete walkways sit with driveways and patios on this site's rate reference; pavers price higher for the joints. These are typical market ranges, not quotes.
You will see $0.15–$0.35 per square foot quoted for sidewalk cleaning in places. That figure is either the paver and brick rate, or a small standalone job where the minimum charge is really setting the price and the per-foot number is just the arithmetic afterwards. On a plain concrete walk measured alongside a driveway, the real rate is the flatwork rate.
To turn an area into a price with your own rate and minimum, use the price per square foot calculator, or the commercial estimate calculator for storefront frontage.
Winding Path? Trace It From Satellite
A walkway that curves, changes width, or wraps a building has no single length × width. Trace the real edge and the area comes back on its own.
Search the Property Address
Type in any residential or commercial address. The satellite view loads instantly, with the walkways, driveway, and frontage all in one frame.
Trace the Walkway
Zoom all the way in and place a point at each corner. On a curved path, more points along the bend means a closer trace. Draw each separate walk as its own shape.
Add It to the Job
The walkway totals alongside the driveway and patio in the same project, so the bundled quote comes from one set of real measurements.
The Surface That Gets Left Off the Quote
Sidewalks are small enough to feel like a rounding error and common enough to show up on nearly every property. That combination is why they get eyeballed — quoted as “and the walkway” with a number pulled out of the air, or forgotten entirely and then washed for free because the customer assumed it was included.
On a residential job that's twenty or thirty dollars. On a commercial frontage it's thousands of square feet, and it is the difference between a bid that holds and one that doesn't. Either way the fix is the same: measure it with everything else, at the same time, from the same satellite view.
Because you're already on the property in the imagery, adding the walkway costs you about thirty seconds — and it turns a vague line item into a specific one that the customer can see you actually measured.
Every Walkway, Measured Accurately
Straight, curved, residential, or a whole commercial frontage — trace any shape with satellite precision.
Residential Front Walks
The run from the driveway or street to the front door. Small, but it's the first thing a customer sees — and it rides along with the driveway job.
City Sidewalk Frontage
The public walk across the front of a lot. Usually a straight run at a consistent width, which makes it a two-point measurement.
Curved and Garden Paths
Winding walkways with no single length or width. Trace the real outline — this is the case hand formulas can't do at all.
Storefront and Plaza Walkways
Wide commercial frontage with gum and foot traffic. Priced above open lot, and measured as its own zone in a commercial bid.
Paver and Brick Walkways
Measured identically, priced higher — joints need lower pressure and more passes, and often re-sanding after.
HOA and Campus Walk Networks
Miles of connected walkway across a community. Measure segment by segment and hand the board one itemized total.
Sidewalk Square Footage — Common Questions
Widths, crossings, and how to price a walkway that isn't worth its own trip.
Multiply the length of the run by its width. A 60 ft sidewalk at 5 ft wide is 300 square feet. If the walkway changes width partway along, split it at the transition and treat each stretch as its own run. Subtract driveway crossings and aprons that belong to a different surface, and add landings, stoops, and step pads as separate sections.
Residential front walks are usually 3–4 ft wide. Public sidewalks along a street are commonly 4–6 ft, with 5 ft being the most-built width, and ADA accessible routes require a minimum 36-inch clear width — which is a large part of why 4 ft became the practical floor. Commercial storefront walkways are much wider, typically 6–12 ft. If you know the length but are guessing at the width, that guess is where almost all the error in a sidewalk estimate comes from.
Multiply the linear footage by the width. Sidewalks get described in linear feet because that's how they're walked and how concrete work is often specified, but cleaning, sealing, and coating are all priced by area. 300 linear feet of 5 ft walkway is 1,500 square feet — and at a per-square-foot rate that difference is the entire quote, so it's worth getting the width right rather than assuming.
It depends on the scope, which is exactly why it's worth being deliberate about. Where a driveway crosses a public sidewalk, that section is usually the driveway apron and gets measured with the driveway — especially if the two are priced at different rates or one is out of scope. If you're washing the whole frontage at one rate, leave it in. The calculator on this page subtracts crossings so you can quote it either way.
Yes. The polygon tool places points anywhere on the satellite image, so you can follow a curving garden path or a walkway that wraps a building. The more points you place along the curve, the closer the traced shape follows the real edge. That's the case where length × width genuinely can't help you — a winding path has no single length or width.
Accurate on length, less forgiving on width. Satellite measurement typically lands within 1–3% on open hardscape, but that assumes the edges are clearly visible, and a 4 ft walkway has very little margin — a foot of misjudged width is a 25% error. Zoom all the way in before you place points, and where a walkway runs under tree cover, measure the width on a clear section and apply it to the shaded run.
Residential concrete walkways are priced like other residential flatwork — roughly $0.08–$0.18 per square foot — and commercial storefront sidewalk commonly runs $0.08–$0.14 per square foot. Paver and brick walkways price higher, roughly $0.15–$0.35, because the joints need lower pressure and more passes. Where you see higher per-foot numbers quoted for sidewalks, it's usually a small standalone job where the minimum charge is really setting the price, not the rate.
Rarely, and that's the practical point. A 200 sq ft front walk at $0.15 is $30 of work, which doesn't cover the drive, the setup, or the water. Sidewalks make money as an add-on to a driveway or patio job you're already set up for, or in volume on a commercial frontage. Measure them alongside the main surface, quote them as a bundled line, and let your job minimum handle the rest.
