Utile - Dimensiuni formate standard A0 - A10, B0 - B10, C0 - C10

 

De-a lungul timpului au existat mai multe formate in dimesionarea hartiilor. Astazi, exista standarde ISO internationale cum ar fi formatele A4, A3, B4 etc.

Greutatea diverselor tipuri de hartie se raporteaza la suprafata de 1 mp, iar formatul A0 este definit ca formatul standard cu aceasta suprafata.

Principiul de dimensionare ale formatelor este urmatorul: fiecare format mai mic reprezinta jumatate din formatul anterior. Asadar, daca taiem o coala A4 pe jumatate obtinem 2 coli A5.

 

 

In America de Nord exista anumite standarde locale cum ar fi letter, legal, ledger etc
