Commentary for Shabbat 13:4

שִׁעוּר הַמְלַבֵּן וְהַמְנַפֵּץ וְהַצּוֹבֵעַ וְהַטּוֹוֶה, כִּמְלֹא רֹחַב הַסִּיט כָּפוּל. וְהָאוֹרֵג שְׁנֵי חוּטִין, שִׁעוּרוֹ כִּמְלֹא הַסִּיט:

The size (for liability) for whitening [wool], beating, dyeing, and spinning, [which are all avoth melachoth] is [to spin from that wool a strand whose length is] double the full breadth of a sit. [A sit is the full-breadth distance between the middle finger and the index finger. And double this distance is "double a sit." And the distance between the thumb and the index finger is also double the breadth of a sit, for it is double the distance between the middle finger and the index finger.] If one weaves two strands, its size (for liability) [in the breadth of the garment] is a full sit. [For even if he did not weave them along the full breadth of the garment, he is liable.]
