Driveway Square Footage Calculator
Measure any driveway from satellite — straight, curved, circular, or multi-section — without a tape measure or site visit.
SurfaceMeasure lets you pull up any address on satellite imagery, draw the driveway outline, and get exact square footage in minutes. Whether you're quoting a sealcoat job, a paving replacement, or a decorative concrete overlay, accurate measurements are ready before you ever leave the office.

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 to Calculate Driveway Square Footage
Driveway square footage is length × width in feet. A 20 ft wide by 40 ft deep driveway is 800 square feet. The only complication is that most driveways aren't a single clean rectangle, so you break the shape into parts, measure each one, and add the results.
To convert once you have the total: divide square feet by 9 for square yards (how asphalt and sealcoat are often priced), or by 43,560 for acres. The calculator above does both automatically.
Measuring on site with a tape or wheel instead? Our step-by-step guide to measuring a driveway walks through where to start and end each measurement, and the mistakes that throw a number off.
How Big Is a Typical Driveway?
Most residential driveways fall between 200 and 1,000 square feet. Use these as a sanity check on a number you just calculated — not as a substitute for measuring the actual property.
| Driveway | Typical size | Approx. area |
|---|---|---|
| Single-car, one car deep10 × 20 ft | 10 × 20 ft | 200 sq ft |
| Single-car, two cars deep10 × 40 ft | 10 × 40 ft | 400 sq ft |
| Two-car, one car deep20 × 20 ft | 20 × 20 ft | 400 sq ft |
| Two-car, two cars deep20 × 40 ft | 20 × 40 ft | 800 sq ft |
| Long drive to detached garage10 × 60–100 ft | 10 × 60–100 ft | 600–1,000 sq ft |
| Circular turnaroundvaries | varies | 800–1,500 sq ft |
Widths assume roughly 9–10 ft per car and 18–20 ft of depth per car length. Lot shape, setbacks, and turnarounds move these numbers substantially.
Curved Driveway? Measure It From Satellite
When length × width won't do it — curves, circular turnarounds, or a driveway you can't walk — trace the real outline instead. Address to square footage in under three minutes.
Search the Property Address
Type in any residential or commercial address. The satellite view loads instantly, giving you a clear overhead view of the driveway and surrounding property.
Trace the Driveway Shape
Use the polygon drawing tool to click around the driveway outline. Works on straight driveways, curved approaches, circular turnarounds, aprons, and multi-section layouts.
Get Instant Square Footage
SurfaceMeasure calculates the enclosed area automatically. You'll see the square footage immediately. Save the project, export the measurement, and move on to the next job.
The Faster Way to Quote Driveway Work
For sealcoating contractors, paving companies, and concrete pros, the traditional measurement process means driving to the property, walking the driveway, measuring width and length with a tape or wheel, sketching out irregular sections by hand, and doing the math on the way back. On a full day of estimating, that adds up fast — sometimes five or six site visits just to get numbers for quotes that might not even close.
SurfaceMeasure turns that into a browser tab. You search the address, trace the driveway shape on the satellite image, and have the square footage in minutes. For a straight residential driveway, it takes under three minutes. For a larger commercial property with multiple paved sections, maybe ten. Either way, you're writing the estimate before the competition has even left their shop.
The tool handles any shape — straight approaches, curved driveways, circular turnarounds, U-shaped layouts, and driveways with separate apron sections. You don't need a perfect rectangle to get a useful number.
Every Driveway Configuration, Measured Accurately
Straight, curved, commercial, or multi-unit — trace any shape with satellite precision.
Straight Residential Driveways
The standard single-car or double-wide driveway. Trace the outline in seconds and get square footage instantly.
Curved and Sweeping Driveways
Place polygon points along the curve to follow the exact shape. Works for gentle bends and dramatic sweeping approaches alike.
Circular and Turnaround Driveways
Round driveways, loop driveways, and circular turnarounds. Trace the shape with enough points to capture the curve accurately.
Multi-Section Driveways
Driveways with a separate apron, widened sections near the garage, or branch paths. Measure each section separately and add them together.
Commercial Parking Lots and Approaches
Large paved surfaces, entry drives, and commercial parking areas. SurfaceMeasure works at any scale — residential or commercial.
HOA and Multi-Unit Properties
Measure driveways across an entire HOA or apartment complex. Save each property as a separate project and export measurements in bulk.

Driveway Square Footage — Common Questions
Everything contractors need to know about remote driveway measurement.
For a rectangular driveway, you multiply length by width. For anything irregular — curved, L-shaped, or multi-section — you need to break it into segments and add them together. SurfaceMeasure skips the manual math entirely: you trace the shape on a satellite image and the area is calculated automatically, regardless of how complex the driveway is.
A single-car driveway one car length deep is roughly 10 × 20 ft, or about 200 sq ft. A standard two-car driveway is around 20 × 20 ft (400 sq ft), and a two-car driveway two car lengths deep runs about 20 × 40 ft, or 800 sq ft. Long driveways to a detached garage often land between 600 and 1,200 sq ft, and circular turnarounds typically fall between 800 and 1,500 sq ft. These are common ranges, not rules — driveway sizes vary a lot by lot shape and setback, so measure before you quote.
Yes. The polygon drawing tool works by placing points anywhere on the satellite image, so you can follow curves, angles, and irregular edges with as much precision as you need. The more points you place along a curve, the more accurately the shape is traced.
For most driveways, satellite-based measurement is accurate within a few percent of an in-person tape measurement — accurate enough for material estimation, quoting, and job planning. Factors like image resolution and the angle of satellite capture can introduce minor variation, but in practice, SurfaceMeasure measurements are consistently close enough for professional estimates.
Yes. You can draw multiple shapes within the same project — useful for driveways with a separate apron, a widened garage pad, or split sections. Each shape is measured independently, so you can see the breakdown and the total.
Yes. The tool works at any scale. Commercial entry drives, parking lot approaches, large paved surfaces, and multi-unit property driveways can all be measured the same way as a residential driveway — just with more polygon points.
No. SurfaceMeasure uses satellite imagery, so as long as the property is visible from above (which covers virtually all addresses in the U.S.), you can measure it without leaving your desk. Many contractors use it to measure properties before deciding whether a physical visit is necessary.
SurfaceMeasure starts with 1 free measurement — no credit card required. Paid plans are $9.99 per month or $99.99 per year. For contractors doing regular estimates, it typically saves more time on the first job than the entire monthly cost.
