Evolution of the effective radius (top) and Sérsic index (bottom) for galaxies in our sample. The triangle with solid dashed lines are the median values for low-mass galaxies (10^9.5 M_⊙ ≤ M_* < 10^10.5 M_⊙), while the circles with solid lines are the means for high-mass galaxies (M_* ≥ 10^10.5 M_⊙). Error bars define the 16th and 84th percentiles of the distributions. The EGS and CEERS images are colour-coded by the red and blue lines, respectively.
