Line Striping Paint Calculator

Estimate how many gallons of line-striping paint you need for parking spaces or driveway markings.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Striping paint needed

3 gallons

Check your inputs

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.

Total line length
656.17 linear ft

With the figures above, the striping paint needed comes to 3 gallons. Note that total line length sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. The method behind this is well established, though site conditions and material batches will move it somewhat. This is calculated for United States and cites IRC 2024. Building in another market?

Estimated cost — your price

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. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Regulatory standards & verification citations

  • A standard 4 in wide traffic paint line covers approximately 300 linear ft per gallon, a widely cited coverage rate for line-striping paint

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.
