Abstract: The ratios of spectral line-depths are powerful indicators of the effective temperature. Thirty-two functional formulas to estimate the effective temperatures from line-depth ratios for Cepheids and F-G supergiants are offered. For high-quality spectra we find errors in the temperature as small as 10-15 K. These calibrations are only little sensitive to other stellar parameters and allow to derive highly precise T-eff for supergiants in the range 4700-6700 K.
