Papiergewichte erklärt: 250g/m² vs 600g/m² Baumwolle
Artikel auf Englisch — Übersetzung folgt.
GSM means grams per square meter. Standard invitation card is 250–300gsm — sturdy, mails well. 600gsm cotton is double-thick, letterpress-grade, with a soft tactile edge clients associate with luxury.
Heavier is not always better: 600gsm needs higher postage and can't be folded. Use 250–350gsm for pocketfolds and multi-piece suites, 600gsm for single statement cards.
