Two important parameters that characterize galaxies are their sizes and luminosities. We explore the bi-variate distribution of size and luminosity for high-redshift galaxies using data from the Great Observatories Origins Deep Survey (GOODS) and the Hubble Ultra Deep Field. With careful attention to selection effects and measurement biases, we measure evolution in this distribution from redshifts z=1 to z=6 and explore dependencies on galaxy color and morphology.

Support for this work was provided by NASA through grant GO09583.01-96A from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, under NASA contract NAS5-26555.
