Measure-Up Calculator
Turn square footage into a fast job total. Paste the numbers off your measuring wheel or Google Earth, set your rate per surface, and see the price with your minimum already baked in.
Paste square footage into any surface to see the total.
The $/sqft defaults are directional starting points, not a standard. Real numbers swing with your market, access, chemical cost, and how bad the surface is. Treat this as a fast sanity check, then price against your own booked jobs before you send the quote.
How to measure a property
A good quote starts with honest square footage. You do not need a survey crew. Three field methods cover almost every residential job, and each one feeds a row in the calculator above.
Measuring wheel
The fastest read for anything you can walk: driveways, sidewalks, patios, and pool decks. Roll the length, roll the width, multiply. For an L-shaped drive, break it into rectangles, measure each, and add them. A wheel is cheap and hard to argue with when a customer questions the number.
Google Earth polygon or ruler
Best for roofs and big footprints you cannot safely pace. Open the address, use the polygon or ruler tool to trace the roof or lot, and read the area it returns. Add a pitch factor for steep roofs, since the overhead view flattens the slope and undercounts real surface. It measures from the truck, no ladder needed.
Count the panels for siding
Walls are the awkward one. Measure a single course of vinyl or one panel, then multiply by the number of courses and the wall width. Or measure wall height times width per elevation and subtract the windows and doors. Either way you get a defensible wall area without a lift.
A word on the rates
The $/sqft defaults in the tool are directional, not a standard. There is no national price sheet for pressure washing, and the ranges you see quoted in forums swing with region, access, chemical cost, and how heavy the growth is. Use the defaults to sanity-check a number, then replace them with the rates your own route actually books at. That is the only figure that pays your fuel bill.
Want a different angle on the price? The pricing calculator builds an estimate from production rate and crew cost instead of area, and the cost calculator breaks down what a job costs you before you mark it up. Run all three when a bid feels off.
Questions operators ask
How do I measure square footage for a pressure washing quote?
Use the right tool for the surface. A measuring wheel is fastest for driveways, sidewalks, and other flatwork you can walk. Google Earth or a mapping app measures roofs and large footprints from above without a ladder. For siding, count the panels: measure one panel, multiply by the count, or measure wall height times width and subtract windows and doors. Then drop each number into the matching surface row.
What should I charge per square foot for pressure washing?
Common working ranges are roughly 0.13 to 0.20 for house siding, 0.10 to 0.15 for concrete flatwork, 0.25 to 0.45 for roofs because of the height and steep-slope risk, and 0.15 to 0.25 for wood. These are directional starting points, not a standard. Your real rate depends on your market, access, chemical cost, and drive time, so confirm it against the jobs you actually book.
How does a minimum charge work?
A minimum charge is the floor you will not price below, no matter how small the area is. Drive time, setup, teardown, and chemical cost do not shrink to zero on a tiny job. If the measured square footage prices out under your minimum, the job bills at the minimum instead. This tool applies that floor automatically once you enter your number.
Is this measure-up calculator free?
Yes. No login, no paywall. It runs entirely in your browser and nothing you enter is sent anywhere. Some field-service apps charge a monthly fee for the same square-footage math.
