We measure the size-mass relation and its evolution between redshifts1$<z<$3, using galaxies lensed by six foreground Hubble Frontier Fieldsclusters. The power afforded by strong gravitation lensing allows us to observegalaxies with higher angular resolution beyond current facilities. We select astellar mass limited sample and divide them into star-forming or quiescentclasses based on their rest-frame UVJ colors from the ASTRODEEP catalogs.Source reconstruction is carried out with the recently-released $lenstruction$software, which is built on the multi-purpose gravitational lensing software$lenstronomy$. We derive the empirical relation between size and mass for thelate-type galaxies with $M_{*}>3\times10^{9}M_{\odot}$ at 1$<z<$2.5 and $M_* >5\times 10^{9} M_{\odot}$ at 2.5$<z<$3, and at a fixed stellar mass, we findgalaxy sizes evolve as $R_{eff}\propto (1+z)^{-1.05\pm0.37}$. The intrinsicscatter is $<0.1$ dex at $z<1.5$ but increases to $\sim0.3$ dex at higherredshift. The results are in good agreement with those obtained in blankfields. We evaluate the uncertainties associated with the choice of lens modelby comparing size measurements using five different and publicly availablemodels, finding the choice of lens model leads to a 3.7 % uncertainty of themedian value, and $\sim 25$ % scatter for individual galaxies. Our workdemonstrates the use of strong lensing magnification to boost resolution doesnot introduce significant uncertainties in this kind of work, and paves the wayfor wholesale applications of the sophisticated lens reconstruction techniqueto higher redshifts and larger samples.
