Cov ntawv loj yog cov qauv raug lees txais ntawm daim ntawv ntawv. Qhov feem ntau yog cov qauv thoob ntiaj teb thiab North American. A1 (tseem hu ua Whatman ntawv) thiab A4 yog thoob ntiaj teb.
Cov Lus Qhia
Kauj ruam 1
Daim ntawv thoob ntiaj teb tus qauv ISO 216, uas tau pom zoo los ntawm German kev tsim khoom qauv pawg thawj coj thaum pib ntawm lub xyoo pua 20th, tau ua raws li kev ntsuas.
Kauj ruam 2
Cov kws tshaj lij hauv engineering thiab lej tau Walter Portsmann pom zoo tias yuav tsum siv 1 m² ntawv los ua lub hauv paus thiab hu nws A0. Txhua daim ntawv loj A-loj muaj qhov sib npaug sib npaug sib npaug sib luag ntawm ib txog rau xwm fab ntawm ob.
Kauj ruam 3
Yog tias daim ntawv A0 yog tais ib nrab, tom qab ntawd koj tau txais daim ntawv ntawm qhov loj me, uas yog hu ua A1.
Kauj ruam 4
Txhawm rau A1 txog A4, quav ntawv Whatman ntawv rau hauv ib nrab thiab txiav raws txoj kab khawm. Koj yuav tau txais daim ntawv A2, uas yog 420 × 594 hli.
Kauj ruam 5
Muab cov ntawv no ib nrab thiab ua zoo ib yam. Tam sim no koj muaj A3 (297 × 420 hli) ntawm tes. Ib daim ntawv ntawm qhov loj me no feem ntau siv los ntawm cov tub ntxhais kawm rau ntau qhov duab. Yog tias koj rov ua cov kauj ruam dhau los, koj yuav tau txais hom A4 uas koj xav tau nrog qhov loj me ntawm 210 × 297 hli. Nws yog tus qauv txheem tshaj plaws hauv Russia, siv rau ntau yam ntaub ntawv thiab luam ntawv. Nws hloov tawm tias hom ntawv A1 muaj 8 A4 los xij.
Kauj Ruam 6
Yog tias koj txuas ntxiv quav ib daim ntawv txuas ntxiv ua ib nrab hauv tib txoj kev, koj yuav tau txais cov ntawv me me tsawg tshaj plaws ntawm tus lej 10 (A10), ntsuas 26 × 37 mm.
Kauj Ruam 7
Ntxiv nrog rau tus qauv North Asmeskas (suav tias yog kev ua haujlwm hauv Tebchaws Meskas thiab Philippines) thiab thoob ntiaj teb, muaj txheej txheem sau ntawv Nyij Pooj.
Kauj ruam 8
Thaum Lub Caij Renaissance, lub tswvyim ntawm "seem xim" tau tshwm sim, uas tau siv los ntawm cov neeg pleev kob thiab lwm tus kws tshaj lij. Thiab kom txog rau thaum xyoo pua 20, qhov sib piv ntawm ob sab ntawm daim ntawv yog 1: 1, 618. Tab sis tus qauv no tsis tuaj yeem pib hauv paus hauv kev luam ntawv, txij li thaum daim ntawv ntsaws rau hauv ib nrab, hom ntawv ntawm phau ntawv ua tsis yooj yim rau tus nyeem rau nkag siab cov ntaub ntawv.
