The choice of grammage for common cultural and educational materials mainly depends on the intended use and paper type, ranging from 24g/m² Bible paper to 400g/m² white cardstock. Different grammage weights correspond to different application scenarios.
Office and Cultural Papers This type of paper is the most widely used in daily life, and grammage directly affects printing quality and feel:
Copier/Printer Paper: Common grammage weights are 70g/m² (economy), 80g/m² (standard), and 100g/m² (extra thick). 80g/m² is considered the "golden grammage" for office use, suitable for double-sided printing and formal documents, offering good stiffness and minimal ink bleed-through.
Offset Paper (Offset Printing Paper): Common grammage range is 70–120g/m², suitable for book pages, magazines, and brochures. Textbooks and supplementary materials often use 80–100g/m², balancing cost and reading experience.
Writing paper: Commonly used at 60–80 g/m², for notebooks, notepads, envelopes, etc., requiring non-bleeding ink and a dense texture.
Newsprint: Standard weight 45–52 g/m², commonly 48 g/m² and 50 g/m², thin and soft, used for newspapers and periodicals.
Bible/dictionary paper: Weight only 24–40 g/m², thin yet tough, specifically used for thick books such as dictionaries and Bibles.
