The first steps of this lesson
Step 1: A Stripe Is a Long Thin Rectangle
Paint is sold by the gallon and covers an area, but a striping take-off is measured in linear feet. Convert every line to area: length in feet times width in feet. A 4-inch line is 4 / 12 = 0.333 ft wide, so 2,400 LF of 4-inch line is 2,400 x 0.333 = 800 square feet. The 2026 California MUTCD Section 3A.04 describes a normal line as 4 to 6 inches wide and says lines on local agency roadways are a minimum of 4 inches wide (6 inches on State highways).
Step 2: Use the Published Coverage Rate
The 2025 Caltrans Standard Specifications, Section 84-2.03B(5), give the paint rates: apply traffic stripes and pavement markings in 1 coat on existing pavement at an approximate rate of 107 sq ft/gal. On a new pavement surface apply 2 coats, the 1st coat must be dry before the 2nd, at approximately 215 sq ft/gal for each coat. The stated rates are approximate, so they are an estimating basis, not a guarantee.
