  Future long-baseline experiments will play an important role in exploring
physics beyond the standard model. One such new physics concept is the large
extra dimension (LED), which provides an elegant solution to the hierarchy
problem. This model also explains the small neutrino mass in a natural way. The
presence of LED modifies the standard neutrino oscillation probabilities.
Hence, the long-baseline experiments are sensitive to the LED parameters. We
explore the potential of the three future long-baseline neutrino experiments,
namely T2HK, ESSnuSB, and DUNE, to probe the LED parameter space. We also
compare the capability of the charged and neutral current measurements at DUNE
to constrain the LED model. We find that T2HK will provide more stringent
bounds on the largest compactification radius ($R_{\rm{ED}}$) compared to the
DUNE and ESSnuSB experiments. At $90\%$ C.L., T2HK can exclude $R_{\rm{ED}}\sim
0.45~(0.425)$ $\mu$m for the normal (inverted) mass hierarchy scenario.
