Ngokusho ISO iphepha ekuqaleni yizigaba ezintathu eziyinhloko. Ngesisekelo esithathwe leaf endaweni eyodwa imitha square. Ngakho ubukhulu oluhambisana A0 format. Kukholakala ubude nobubanzi mm. Njengoba ojwayelekile, bonke abanye osayizi iphepha zinqunywa sokuhlukanisa ohlangothini elide kakhulu kuya amabili, okungukuthi, uma i-A0 (841x1189) ukuncishiselwa nengxenye, sithola 594h841. Lokhu kuyoba usayizi A1, njll
Ukuze uthole ukwaziswa isizinda uyothwala bonke osayizi ekilasini A ethebuleni.

Kodwa e-Europe, ekukhiqizweni ayikwazi esekelwe yimuphi ngohlobo oluthile. Isizathu siwukuthi kakhulu futhi esetshenziswa kabanzi imishini yokunyathelisa ukuthi ingasebenza emhlabeni ezanelisayo zabathengi isidingo. Yingakho kukhona iphepha nezakhiwo Class B. Basuke kuchazwa ngokuthi kusho weJiyomethri phakathi A. ekilasini angomakhelwane Lokho, B1 weJiyomethri kusho phakathi A0 ne-A1. Futhi kuyafana ifomethi S-class - kuba asho weJiyomethri phakathi ngetakhiwo A no B inombolo efanayo. Lokho incwadi ebhaliwe eshidini A4, elise kahle imvilophu format C4 futhi ishidi A5 ngaphandle kwezinkinga itholakala i C5 imvilophi.

Konke lokhu izakhiwo edging okungukuthi, kuba nenkundla ishidi izincwadi isiqedile.
On emakhasini yelucwaningo ngokuvamile ukudideka ngefomethi kanye izinga. Amakilasi A, B, no-C kunoma isiphi isimo akufanele kudidaniswe iphepha futhi isigaba A +, B, B +, C, C + - futhi okuphambene nalokho. Esimweni sokuqala - lilingene ngobukhulu, okwesibili - ibanga kanye izakhiwo. Izigaba ngenhla kuchaza izinga iphepha imingcele ethile, njengengcebo ukuminyana, mhlophe, umswakama, zinyakaze conductivity, olubushelelezi, maholoholo, ukujiya, ukuqina. Ngakho, izigaba kunqunywa izinga, okungukuthi iphepha okunethezeka isigaba - kungcono A, sithola okufanele ngemali esiyikhokhayo - isigaba iphepha ekilasini iphepha umnotho - S.
