The holographic cut-off, in the formalism of generalized holographic darkenergy (HDE), is generalized to depend on $L_\mathrm{IR} = L_\mathrm{IR} \left(L_\mathrm{p}, \dot L_\mathrm{p}, \ddot L_\mathrm{p}, \cdots, L_\mathrm{f}, \dotL_\mathrm{f}, \cdots, a\right)$, where $L_\mathrm{p}$ and $L_\mathrm{f}$ arethe particle horizon and future horizon respectively, and $a$ is the scalefactor of the universe. Based on such formalism, we showed that the Barrowentropic dark energy (DE) model is equivalent to the generalized HDE where therespective holographic cut-off is determined by two ways -- (1) in terms ofparticle horizon and its derivative and (2) in terms of future horizon and itsderivative. Interestingly, such cut-off turns out to depend up-to first orderderivative of $L_\mathrm{p}$ or $L_\mathrm{f}$ respectively. Such equivalencebetween the Barrow entropic dark energy and the generalized HDE is extended tothe scenario where the exponent of the Barrow entropy allows to vary with thecosmological expansion of the universe. In both the cases (whether the Barrowexponent is a constant or varies with the cosmological evolution), we determineeffective equation of state (EoS) parameter from the generalized holographicpoint of view, which, by comparing with the Barrow DE EoS parameter, furtherensures the equivalence between the Barrow entropic dark energy and thegeneralized HDE.
