We find that the dependence of the critical supercurrent $I_{c}$ on $W$ is drastically different for different types of the edges. For \\textit{smooth} and \\textit{armchair} edges at low concentration of the carriers $I_{c}$ decreases monotonically with decreasing $W/L$ and tends to a constant minimum for a narrow strip $W/L\\lesssim1$. The minimum supercurrent is zero for smooth edges but has a finite value $e\\Delta_{0}/\\hbar$ for the armchair edges.
