SettingsSettings for this calculationUS
The combined length of every painted line on the court.
Add up the length of every boundary line, free-throw line, key, arc, and other marked line in the court layout.
The painted width of each line.
Most gym and court lines are painted about 2 in (50 mm) wide, though some sports specify a different standard width — check the governing body's rules for your sport.
The area one unit of line-marking paint covers, per the product's data sheet.
Coverage rate depends on the paint formulation (water-based acrylic, solvent-based, epoxy) and the floor's porosity — use the rated coverage from your specific product's technical data sheet rather than a generic estimate.

How this was calculated
Formula source(s)
- Line marking area = total line length × line width; paint needed = line area ÷ the paint product's rated coverage rate

What this calculation does not cover
- COURT LINES ARE A SPECIFICATION, NOT A LAYOUT CHOICE. The governing body for each sport sets line width, colour and position, and a court marked to the wrong width is wrong regardless of how much paint it took — this computes a quantity from dimensions you supply and cannot check them.
- A multi-sport hall carries several games on one floor, and the shared area is painted repeatedly in different colours. Total the lines per sport separately: overlapping runs are not one length, and each colour is bought separately.
- Coverage on a sealed sports floor differs from coverage on a porous outdoor surface by more than any waste factor. A sprung timber floor with a finish on it takes very little; an outdoor macadam court takes several times as much.
- Says nothing about the finish. An indoor court line is laid under or over a floor seal depending on the system, and applying line paint to the wrong side of that sequence is what makes it lift.
- The result is one pooled volume, and line paint is never bought that way. A multi-sport floor carries a separate color per sport, each in its own can with its own smallest available size, so a single pooled figure is really four part-used containers — split the line length by color before ordering and expect the sum of the cans to exceed this total.
- Paint is the smaller half of the materials. Every line is masked down both sides, so tape alone runs to twice the total line length entered above, plus the paper or film keeping overspray off a finished floor — and on a gym floor the pulling and laying of that tape, not the painting, is what fills the day.
- On a wood floor the lines live under the finish rather than on top of it. The seal and finish coats that go over them are quantified from the whole floor area, not the line area, and they have to be compatible with the line paint — pair a solvent line paint with the wrong finish and the color bleeds or the finish lifts along every line on the court.

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.
