Grammage and basis weight, in the pulp and paper industry, are the area density of a paper product, that is, its mass per unit of area. Two ways of expressing grammage are commonly used: * Expressed in grams (g) per square meter (g/m2), regardless of its thickness. This is the measure used in most parts of the world. It is often notated as gsm on paper product labels and spec sheets. * Expressed in terms of the mass per number of sheets of a specific paper size, known as basis weight. The convention used in the United States and a few other countries using US-standard paper sizes is pounds (lb) per a ream of 500 (or in some cases 1000) sheets of a given (raw, still uncut) basis size. Japanese paper is expressed as the weight in kilograms (kg) per 1,000 sheets.

  • Il termine grammatura è un lemma tecnico usato nel campo della tipografia e, in generale, del settore della produzione e del consumo della carta da legno e dei suoi derivati.
  • Gramatura ou Gramagem é a medida da massa pela área de um papel, denota-se como uma densidade de área ou densidade superficial, expressa em gramas por metro quadrado (g/m²). Sua especificação foi padronizada pela norma ISO 536. Quanto maior for a gramatura, mais grosso será o papel. A gramatura é fator importante dos custos de impressão. Na distribuição, o fator importante é o peso final, principalmente quando enviado por meio da Empresa Brasileira de Correios e Telégrafos, que cobra por peso.
  • Se entiende por gramaje o peso base, en la industria papelera y otras textiles, la densidad superficial de papel (u otro material), esto es, su masa por unidad de área. Las dos maneras más comunes de expresar el gramaje son:
  • Gramatura papieru – masa (pot. „ciężar”) wyrobu papierniczego wyrażona w gramach na metr kwadratowy czy dawniej (w krajach anglosaskich) w funtach na ryzę. Pośrednio parametr ten przekłada się na grubość papieru: najczęściej papier o gramaturze 100 g/m² ma grubość 0,1 mm (z dokładnością ok. 20%). Dokładna grubość zależy jednak od jego wolumenu i np. w przypadku tzw. papierów objętościowych ten przelicznik nie ma już zastosowania.
  • Gramatur adalah istilah untuk menunjuk ukuran berat kertas yang beredar di pasaran. Satuan yang dipergunakan untuk menghitung berat kertas adalah gram per square meter (gsm) atau (g/m2). Terdapat beberapa kelompok gramatur kertas, yakni 70-80 gsm, 100-150 gsm, 190-260 gsm dan 270-310 gsm.
  • Als Quadratmetergewicht, Grammgewicht oder Grammatur bezeichnet man im Druck das Flächengewicht von Papier oder allgemein bedruckbaren Stoffen wie Folien oder Textilien, ausgedrückt in Gramm pro Quadratmeter.Dabei unterscheidet man abhängig vom Gewicht die folgenden Papiersorten:
  • Η επιφανειακή πυκνότητα χαρτιού (paper density, grammage), είναι ένα φυσικό μέγεθος που χαρακτηρίζει ένα χαρτί ή ένα , και αναφέρεται στην επιφανειακή του μάζα, δηλαδή στη μάζα ανά μονάδα επιφάνειας. Η μονάδα μέτρησης είναι συνήθως το γραμμάριο ανά τετραγωνικό μέτρο (g/m²). Ένα χαρτί είναι πιο εύκαμπτο όταν έχει μικρή επιφανειακή πυκνότητα, ενώ όταν αυτή είναι αυξημένη, είναι πιο άκαμπτο. Η επιφανειακή πυκνότητα χαρτιού ορίζεται από τα πρότυπα ISO 536 και 4046.
  • Le grammage, également appelé force du papier, est une grandeur caractérisant un papier ou un carton, correspondant à sa masse surfacique, c'est-à-dire sa masse par unité de surface. L'unité est typiquement le gramme par mètre carré (g/m2). Un papier est d'autant plus souple que son grammage est faible, il est d'autant plus robuste que son grammage est élevé. Le grammage est défini par les normes ISO 536 et 4046-5. Un papier plus léger (60 g/m2 par exemple) aura tendance à « bourrer » plus facilement dans une imprimante grand public, tandis qu'un papier photo fait typiquement de 150 à 200 g/m2.
