Cov ntawv luam tawm uas tau pom zoo yog suav tias yog daim ntawv ntawm 70x90 cm hom ntawv luam tawm Cov ntawv xov xwm thiab cov ntawv xov xwm tshaj tawm yog sib tshooj ntawm cov ntawv luam tawm. Piv txwv, A2 yog ib nrab ntawm cov koog no, A3 yog lub quarter, thiab A4 yog yim. Cov qauv no tseem siv tau niaj hnub no. Txawm li cas los xij, cov phau ntawv thiab cov nplooj ntawv magazine tuaj yeem muaj lwm qhov ntau thiab tsawg. Ib qho ntxiv, niaj hnub luam ntawv thev naus laus zis tso cai sib txawv ntawm cov ntawv sau rau ntawm tib qhov chaw, vim tias qhov ntau thiab tsawg thiab cov qauv xaiv sib txawv tuaj yeem siv.
