What is Paper Weight?

Paper weight is measured in GSM (grams per square meter)—the weight of one square meter of paper. Higher GSM means thicker, more substantial paper. But there's more to consider than just weight.

Understanding GSM Ranges

60-80 GSM Lightweight—printer paper, memo pads
90-120 GSM Standard—letterheads, flyers, newsletters
130-170 GSM Medium—brochures, flyers, promotions
200-300 GSM Heavy—booklet covers, packaging
350+ GSM Extra Heavy—luxury cards, rigid packaging

Choosing the Right Weight

Business Cards

350-400 GSM is ideal. Thicker paper feels premium and survives in wallets/pockets. Consider soft-touch lamination for extra durability.

Brochures & Flyers

130-170 GSM works well for handouts. Use 200-250 GSM for premium handouts that need to stand out.

Packaging

300-400 GSM for boxes. Add corrugated layers for shipping boxes. Consider moisture resistance for food packaging.

Booklets & Manuals

Cover: 250-300 GSM. Interior pages: 100-120 GSM. Heavier interior pages feel more premium.

It's Not Just About Weight
