We quantify the amount of data needed in order to measure the size of the solar core with future experiments looking at elastic scattering between electrons and solar neutrinos. The directions of the electrons immediately after scattering are strongly correlated with the incident directions of the neutrinos, however this is degraded significantly by the subsequent scattering of these electrons in the detector medium. We generate distributions of such electrons for different sizes of the solar core, and use a maximum likelihood analysis to make projections for future experimental sensitivity. We find that after approximately 5 years of data-taking an experiment the size of Hyper Kamiokande could measure the solar core radius with an uncertainty of 20% of the total solar radius at 95% confidence, and could exclude the scenario where the neutrinos are produced throughout the entire sun at 3 $\sigma$.
