Text Weight Papers

​

• 50# Text ≈ 75 GSM

• 60# Text ≈ 90 GSM

• 70# Text ≈ 105 GSM

• 80# Text ≈ 120 GSM

• 100# Text ≈ 150 GSM

​

Cover Weight Papers

​

• 65# Cover ≈ 175 GSM

• 80# Cover ≈ 215 GSM

• 100# Cover ≈ 270 GSM

• 110# Cover ≈ 300 GSM

• 130# Cover ≈ 350 GSM

​​

• Text: 1 lb = 1.48 GSM

• Cover: 1 lb = 2.708 GSM
