The invention relates to a method for measuring the coverage density of multiple components on a surface, in particular skin hair coverage, by dividing the surface to be measured in a number of zones, comparing the visu al appearance of these zones to measuring means comprising reference surfaces assigned with numerical values, so as to allow assigning a numerical value t o the measured zones in function of the visual parameter of said series of reference surfaces. The invention also relates to equipment therefor, comprising grid means for dividing the surface to be measured in zones and means for measuring coverage density, involving several sets of density scal es comprising n reference surfaces with a visual density which serially decreas es by the fractional factors n-1 / n, n-2 / n, , 1 / n.
