Partindo do A0 (841 \u00d7 1189 mm, exatamente 1 m\u00b2), cada passo na s\u00e9rie divide a \u00e1rea por dois, ent\u00e3o o A4 \u00e9 a metade do A3, o A5 \u00e9 a metade do A4 e assim por diante. Isso torna o redimensionamento de documentos entre formatos muito simples \u2014 amplie um A4 em 141% e ele preenche exatamente uma folha A3.<\/p>\n<p>A s\u00e9rie B preenche os intervalos entre os tamanhos A (o B5 fica entre o A4 e o A5) e \u00e9 comum em p\u00f4steres, livros e passaportes. A s\u00e9rie C \u00e9 reservada para envelopes: um envelope C4 comporta uma folha A4 sem dobr\u00e1-la, um C5 comporta um A4 dobrado uma vez e o popular envelope comercial DL comporta um A4 dobrado em tr\u00eas. Envelope e conte\u00fado, portanto, combinam por defini\u00e7\u00e3o, sem precisar adivinhar.<\/p>\n<p>Os tamanhos norte-americanos seguem uma l\u00f3gica diferente: dimens\u00f5es simples baseadas em polegadas, herdadas do papel artesanal hist\u00f3rico. O Letter (8,5 \u00d7 11 in) \u00e9 o formato de escrit\u00f3rio do dia a dia, o Legal (8,5 \u00d7 14 in) \u00e9 usado em contratos e documentos judiciais, e o Tabloid (11 \u00d7 17 in, tamb\u00e9m chamado ANSI B) tem o dobro do Letter. A s\u00e9rie ANSI estende esse padr\u00e3o para desenhos t\u00e9cnicos at\u00e9 o ANSI E (34 \u00d7 44 in). Como o Letter \u00e9 cerca de 6 mm mais largo, mas 18 mm mais curto que o A4, os dois n\u00e3o s\u00e3o intercambi\u00e1veis \u2014 imprimir um documento A4 em Letter ou vice-versa reduz ou corta um pouco o conte\u00fado.<\/p>\n<p>A propor\u00e7\u00e3o exibida no resultado indica o formato da folha: todos os tamanhos ISO mostram 1 : 1,414 (\\(\\sqrt{2}\\)), enquanto os tamanhos norte-americanos usam outras raz\u00f5es \u2014 o Letter \u00e9 1 : 1,294, ou seja, proporcionalmente mais largo.
