Hacham Baruch says there’s a machloket (dispute): What’s a katan (minor)? Most poskim (halachic authorities) hold it’s nine, right? He says the reason why you need that at that point is called kesuto (his garment). Some say everything depends on the person, and for a tall person, you need a longer one. We hold like Maran, that it doesn’t make a difference. He says, amah (cubit), amah al amah. Some say it’s amah al amah, 24 by 24 inches. And some say it’s amah vachatzi al amah vachatzi, 36 by 36 inches. That’s from Chaim Palachi. And some say the shiur (measure) is amah vachatzi in length, 36, and three quarters of an amah in length, which is 36 by 18. And that’s what Rabbi Yosef Chaim says. And some say that it’s enough to make 12 by 18. So the person should try and get a shiur of 24 by 18. That’s what Hacham Baruch says.
He says kol hapachot (minimum). I’m going to tell you not to do like Rabbi Chaim Palachi, 36 by 37, I’m not telling you anything. He says the minimum you should get is 24 by 18. It is—that’s the Ben Ish Chai, 24 by 18. Sorry, sorry, my mistake, yeah. 24 width, right? 30 width? No, that’s 24. It’s a shiur, esrim ve'arba gudalim (thumb-widths), 24. 24 gudalim, that’s one amah ba'orech (length) and 18 ba'rochav (width). That’s what he says; that’s the minimum.
