四分律比丘含注戒本 2.810

2.810

(If width and length accord with the measure, but either does not accord with the measure, both incur an offense. The rest, regarding making it oneself, having another make it, and bhikṣuṇīs making it, are all as above. There is no offense if, having obtained a completed robe from another, one cuts it according to the measure, or if one makes it doubled by folding, there is no offense.)
