When Do Jewish Boys Begin to Wear Their Tallit?

The answer to this question really varies depending on your ancestry and/or community custom. Allow me to share some information:

Jewish men and boys traditionally wear a small fringed tallit (lit.: cloak) under their shirts throughout the day. This garment is known as a tallit kattan (a "small" tallit), and even little children – as young as three years of age – are taught to wear this light four-cornered garment.

The tallit worn during prayer is much larger, it is known as a tallit gadol ("large" tallit).

Traditionally, Eastern European Jewish men begin wearing a tallit gadol for the daily prayers after marriage. Customarily the tallit is a gift from the bride or her family.

Among Western European and Oriental Jews, boys begin wearing the tallit gadol from the age of Bar Mitzvah or even earlier.
