Distribution of galaxy sizes as a function of stellar mass for SFGs across different redshift bins. In each panel, the gray contours enclose 25%, 50%, 75%, and 99% of the sample. The black points with error bars denote the median effective radius and the corresponding standard deviation within stellar mass bins. The solid black line represents the best-fit size–mass relation derived from our analysis. For comparison, we show the results for the 0 < z < 0.5 bin as dashed gray lines in the remaining panels.
