#There are various opinions<ref>This range emanates from the gemara Menachot 40b, where it is dictated that the garment needs to be the size for it to be able to cover the head and majority of a minor. There are different interpretations as to how old the minor is to whom the gemara is referring: The [[Chinuch]] (Shelach: 386) and Bach (16) say the reference is to a 6 or 7 year old, the Tur (16) says 9 years old, and the Radbaz (6, 2:106) explains it to be a 5 year old. There is additionally ambiguity as to whether the majority requirement means that the garment needs to cover the head and then in addition a majority of the child’s body (Radbaz) or if it only needs to cover in total the majority of the child; head included ([[Chinuch]]). Meaning, the question between the Radbaz and Chinuch is whether it would be sufficient if it could cover the child’s head and another 30% to 40% of the rest of it's body, or whether it needs to be able to cover the head and an additional 51% of their body</ref> as to how big the garment needs to be to qualify as a halachically bona fide garment, in order to be able to make a bracha without needing to worry about the possibility of it being a bracha levatala (a bracha said in vein or wasted):

Similarly, the Gra, without specific numbers, was very strict in this regard and required the garment extend down to one’s knees. Also, the Chazon Ish 3:31 concludes that it is best to follow this size requirement. Likewise, the Mishna Brurah (8:17, 16:4) suggests this size to avoid difference of opinions.</ref> There is also an opinion that there is no size requirement at all.<ref>Aruch HaShulchan 16:5</ref>
#Additionally, there are two different opinions for the conversion of one [[amah]], or 6 [[Tefachim]] (fists), to modern [[measurements]]: Rav Chaim Na’eh holds it is 48 cm or 18.9 inches make up an [[amah]], while the Chazon Ish holds it is 57.7 cm or 22.7 inches.
