I am teaching 8th graders how to make Tzitzis. What is the minimum Kosher size 20″ or 22″? Is it better to get a bigger size?
The minimum size of a Talis Koton – Tzitzis is approximately 19 in. wide and 19 in. long on each side until the hole for the neck Which is a size 20 (20 in.).
It would be better to get a bigger size to take in account inaccuracy in the size and the folds that can happen when wearing the Tzitzis.
