Is a size 18 pair of Tzitzis kosher and could you make a Bracha on it, or you need size 20?

 

Size 18 can be Kosher, and you may make a Bracha on it if the garment meets the Halachic minimum size – about 19 inches. See more here. While many size 18 Tzitzis do meet this requirement, it’s not recommended, as it’s difficult to ensure the Shiur will remain fully stretched when worn [see also here]. It’s best to go up to 19 (a newer option on the market), 20, or ideally even larger.
