•We have for the first time, discussed the effect of Ra thoroughly on the evolution of the non-dimensional droplet spreading diameter β for droplet impacting.•We extended previous work on βmax to accommodate Ra effect and the derived empirical correlations of βmax as a function of Ra show good agree...
