Raavad Ratio

Raavad Ratio – 2/8 Strings

String Ratio Rationale

From https://www.tekhelet.com/tying-overview/:

Raavad and the Aruch, based on the Sifre in Shelach hold that one full string (when folded becomes two of the eight strings) must be Tekhelet (Hasagot, Hilchot Tzitzit 1;6)”

Archeaological Support for Raavad Ratio

Notable Articles


  1. The Sifri pretty much explicitly states Raavad’s shittah;
  2. The Beis Yosef/Kesef Mishnah apparently had an incorrect Girsah of the Raavad and assumed that he had the same opinion as Tosafos;
  3. In absence of a solid mesorah (which obviously no one has in regards to Techeiles), you should use logic to decide the Halacha (instead of Paskening by ethnicity),.
