Abstract: We study the variation of granular size and contrast over a solar activity cycle. Two different homogeneous data samples were used, from Pic du Midi and from Hinode. The results do not confirm previous values cited in the literature. From the Hinode data the granulation seems to be constant, the trend found may be of instrumental degradation. We try to explain the result by other observations like the total solar irradiance variation. This variation was small over the past five years and may explain why in the case of Hinode data no significant variations were found.
