We present an analysis of the size growth seen in early-type galaxies over 10Gyr of cosmic time. Our analysis is based on a homogeneous synthesis ofpublished data from 17 spectroscopic surveys observed at similar spatialresolution, augmented by new measurements for galaxies in the Gemini Deep DeepSurvey. In total, our sample contains structural data for 465 galaxies (mainlyearly-type) in the redshift range 0.2<z<2.7. The size evolution ofpassively-evolving galaxies over this redshift range is gradual and continuous,with no evidence for an end or change to the process around z~1, as has beenhinted at by some surveys which analyze subsets of the data in isolation. Thesize growth appears to be independent of stellar mass, with the mass-normalizedhalf-light radius scaling with redshift as R_e (1+z)^(-1.62 +/- 0.34).Surprisingly, this power law seems to be in good agreement with the recentlyreported continuous size evolution of UV-bright galaxies in the redshift rangez~0.5-3.5. It is also in accordance with the predictions from recenttheoretical models.
