The size of the Ezras Israel (where male Israelites are allowed) is 11 Ammos (cubits) long while the Ezras Nashim is so big (135x135 cubits).
Yet, it was the men who had to be Oleh Regel (when the "big crunch" was expected). Even if one says that there was a miracle, it's not so clear that we rely Lechatchila on such miracles.
Why (when they sanctified the Temple Mount) couldn't they have made the Ezras Yisrael larger (at the expense of the Ezras Nashim)?
