We study the evolution of the size-stellar mass relation for a large spectroscopic sample of galaxies in the GOODS-North field up to z ∼ 3.5. The sizes of the galaxies are measured from K_s-band images (corresponding to rest-frame optical/NIR) from the Subaru 8 m telescope. We reproduce earlier results based on photometric redshifts that the sizes of galaxies at a given mass evolve with redshift. Specifically, we compare sizes of UV-bright galaxies at a range of redshifts: Lyman-break galaxies (LBGs) selected through the U-drop technique (z ∼ 2.5-3.5), BM/BX galaxies at z ∼ 1.5-2.5, and GALEX LBGs at low redshift (z ∼ 0.6-1.5). The median sizes of these UV-bright galaxies evolve as (1 + z)^{–1.11±0.13} between z ∼ 0.5and3.5. The UV-bright galaxies are significantly larger than quiescent galaxies at the same mass and redshift by 0.45±0.09 dex. We also verify the correlation between color and stellar mass density of galaxies to high redshifts. The sizes of submillimeter galaxies in the same field are measured and compared with BM/BX galaxies. We find that the median half-light radius of SMGs is 2.90±0.45 kpc, and there is little difference in their size distribution to the UV-bright star-forming galaxies.
