四分律比丘含注戒本 2.772

2.772

If one makes it oneself or instructs another to make it, and upon completion it exceeds [the measure], one commits a falling offense; if it is not completed, or if one makes it for another, all are duṣkṛta. The bhikṣuṇīs commit the same offense. As for non-offense: if one makes the legs eight finger-widths high, or less; if it is given by another, and one cuts it down before using it; or if the legs have come off.
