Kukho konke umqambi noma umuntu onobudlelwano obuthile naye papel futhi i umbono kubalulekile ukuthi wazi futhi ucishe wazi ngekhanda amafomethi wephepha ahlukene asungulwe njengokujwayelekile. Ifomethi ejwayelekile futhi esetshenzisiwe ibizwa ngokuthi DIN, enesilinganiso esingu-1:? 2. Isungulwe ngo-1922 futhi yakhiwa ngunjiniyela waseJalimane uDkt. UWalter Porstmann.
Ngaphakathi kwefomethi ye-DIN singathola okuhlukile okuthathu okwehlukile ezilinganisweni zabo: DIN-A, DIN-B, DIN-C, DIN-D, DIN-E. Futhi okuhlukaniswe ngamanye amafomethi ngokuya ngenombolo okukhulunywa ngayo, i-DIN-A ibe yinde kakhulu ezilinganisweni. Kufanele wazi ukuthi zonke zikhonjiswa njalo ku- millimeters.

El Ifomethi inkomba ye- uchungechunge A ibizwa nge-A0, ubuso bayo obulinganisa u-1 m2. Futhi kusukela kulesi silinganiso kuzalwa izinyathelo ezingezansi. Ifomethi ngayinye ochungechungeni A itholakala ngokuhlukanisa uhlangothi olukhulu lwefomethi ngokushesha ngenhla kwayo, okusho ukuthi, ilandela isilinganiso esingu-1:? 2. Ngale ndlela, i-A1 izoba uhhafu we-A0 ohlangothini lwayo olukhulu, kuthi i-A2 ibe uhhafu we-Ai ohlangothini lwayo olukhulu, bese ngokulingana ngokuhambisana nawo wonke amafomethi kuze kufike ku-A10, okuncane kunakho konke ochungechungeni.
Ngaphakathi kwe-DIN-A, amafomethi asetshenziswa kakhulu nsuku zonke yilawa A-4 (210 x 297 mm) kanye ne- A-3 (297 x 420 mm). Futhi okuvame kakhulu yilezo ezisukela ku-Din-A 5 kuya ku-Din-A10 ngenxa yosayizi wazo omncane.
I-DIN isichazamazwi se- I-Deutsches Institut für Normung (ihunyushwe ngeSpanish, i-German Institute for Standardization).
