73 broadband optical spectra of dwarf stars later than F0 have been obtained from the Nearby Stars Project website. The number of absorption lines is computed for each spectrum between 6000 and 6200 Angstrom. A correlation is found between the density of lines K$\lambda$ and the spectral type. This method is independent of calibration process, does not require high resolution or high signal to noise data and does not make use of a large library of standard spectra.
