We present one of the first comprehensive studies of the variation of galaxy radius with environment beyond the local Universe and demonstrate that large-scale environmental density is correlated with galaxy radius independent of stellar mass and galaxy morphology. We confirm with $>5\\sigma$ confidence that galaxies in denser environments are up to $\\sim25\\%$ larger than their equally massive counterparts with similar morphology in less dense regions of the Universe.
