Measured in widths of cloth.
Traditional bojagi are counted in pok, the width of a bolt from a narrow Korean loom. Gift shops today sell them in centimetres.
폭 (幅, pok) is one loom width of cloth, and bojagi are sized by the number of widths along one side. Court regulations (『상방정례』 and 『탁지준절』) record 1폭 = 7촌. A study of late-Joseon palace bojagi puts one 폭 at about 34-35 cm (estimates 34.4-37.0 cm). The V&A's painted hemp bojagi is made of three loom widths of 35.5 cm each (107 x 107 cm overall). Wikipedia gives about 35 cm per 폭. Court records also use half widths: 폭반 (1.5) and 2폭반 (2.5). They also count fabric needed: a 4폭 홑보 takes 11척 2촌 of cloth, and a 9폭 takes 56척 7촌. That equals 폭² x 7촌 (16 x 7 and 81 x 7); this formula is our own reading of the figures, not stated in the source.

Sources write sizes as '1폭', '두 폭', '2폭 반' and so on. Compound names like 한폭보, 두폭보 and 세폭보 are natural Korean coinages, but they were not found as attested terms in the sources consulted. Use '두 폭 보자기' or '2폭' in the catalog, or flag the compound names as descriptive. The 45/55/70/90/108 cm option set comes from one Korean retailer (crystal/organza gift bojagi). The uses are editorial suggestions, not sourced: no retailer size guide was readable. Confidence: low.
