The combined length of all lines to be painted.

For a parking lot, count the painted LINES rather than the stalls: adjacent stalls share the line between them, so a row of 20 stalls has 21 lines, not 40. Multiply one more than the stalls in a row by the stall depth, add the rows together, then add any perimeter, aisle or directional markings. Counting two lines per stall — the obvious way, and what this help used to suggest — very nearly doubles the paint on a long row.

Coverage assumes a standard 4 in wide line at typical thickness — wider lines, stenciled symbols, or a second coat use more paint per linear ft.

What this calculation does not cover

  • A CAR PARK IS NOT A LENGTH OF LINE. The figure a striping job is quoted on is bays, arrows, hatching, disabled bay symbols and the words painted at the entrance, and each is an area rather than a run — so a total linear footage understates a real layout by a wide margin.
  • The default coverage rate assumes a sprayed 100 mm (4 in) line on sound asphalt. A wider line scales it directly; a porous, weathered or unsealed surface can halve it; and a brush or roller application uses more again.
  • First marking and re-marking are different quantities. Paint over an existing line covers far more readily than paint on bare asphalt, so a repaint on the same layout is not the same order.
  • Coverage is a single fixed figure of 300 linear ft per gallon (24 m per litre) applied to every job, and there is no field for the surface being painted, so a bare aged asphalt lot that soaks up the first pass and a freshly sealcoated one that holds the paint on top are quoted exactly the same.
  • The take-off stays entirely with you, because the arithmetic reads one number and one only: a stripe left out of your tally, the line shared between two adjacent stalls measured twice, or a curbed island paced out as straight run all reach the gallon figure unchallenged.
  • Rounding up to the next whole gallon is the only padding in the answer, so nothing is set aside for the paint sitting in the hose, pump and tank of an airless striper, for the waste at the start and stop of each pass, or for going back over a stripe that wandered.
  • What comes back is a count of whole gallons rather than a count of containers, and the one breakdown line simply restates your footage, so nothing on the page reveals whether that final gallon is nearly spent or barely opened when you choose between 1 gallon cans and 5 gallon pails.
  • Line length is capped at 5,000 m, roughly 16,400 linear ft, so a larger lot or a road contract has to be entered as separate runs, and each run is rounded up to its own whole gallon rather than sharing the leftovers with the others.

Protection this work requires

  • Stop and check first. Paint under later coats in older housing can be lead-based, and sanding or heat-stripping it produces lead dust that is especially harmful to children and to anyone pregnant. Test before you disturb it — this is a job for a tested, controlled method, not a better mask.

Tools and safety for this job

To roll and cut in two coats and prepare a surface for paint. Generic types, no brands, no prices.

  • Joint-compound dust is very fine and travels: a P1/FFP1 mask is the minimum, and a damp-sponge finish avoids most of it.
  • A dust mask does nothing about solvent vapour: ventilate through, and use an organic-vapour (A1) cartridge respirator in an enclosed room.
  • Most fatal falls on small jobs are from under three metres: use a tower or a ladder tied at the top, and never work off the top two rungs.

  • Laying Out a Car Parkuses this calculator

    The vehicle you cannot turn away sets aisle width, stall angle and stall count on a site lot - lay it out from the swept path outward.

  • A court is a geometry problem that ends in a spray gun: how to set out, prove and record the lines before any paint is mixed.

  • A repaint is an alteration, not housekeeping. Why 244 stalls across two lots owe nine accessible spaces, and what that does to a seal-and-stripe.

Frequently asked questions

Does this include stenciled symbols like handicap markings or arrows?
No — this covers straight line footage only. Stencils use a different, more concentrated amount of paint per symbol and should be budgeted separately based on the specific stencil size and count.
How many parking stall lines does a typical lot need?
Each standard stall usually needs 2 side lines the depth of the stall (commonly 18-20 ft) — count your total stalls and multiply, keeping in mind shared lines between adjacent stalls aren't double-painted.
Does line width change the coverage rate?
Yes significantly — a wider line (like 6 in for handicap-accessible markings) uses proportionally more paint per linear ft than the standard 4 in line this estimate assumes.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
