“can somebody give the height minimum / maximum in inches or centimeters”
I found three opinions regarding the size of a tefach:
Rabbi Chaim Neah 7.62 cm
Chazon Ish 9.62 cm
Rabbi Moshe Feinstein 9.00 cm
2.54 cm is exactly one inch. Ten tefachim according to Rabbi Neah would be exactly 30 inches.
“Rav Moshe was the posek hador of that era. “
Many disagreed with him during his lifetime on numerous issues, including Rav Henkin z’tz’l and Rav Soloveitchik z’tz’l.
“until the end of Bays sheni- there was no separation in the bais hamikdosh”
Actually, even at the very end of Bayit Sheni women even entered the azarah itself on occasion — there was actually a women’s entrance on the north side. Women could and did shecht their own korbanot. Chazal didn’t have a problem with any of this.
