Choosing the right paper involves understanding three key factors: the **grade** (Text vs. Cover), the **finish** (Gloss vs. Matte), and the **weight** (lbs vs. gsm).
Text vs. Cover:
"Text" refers to lighter, flexible papers used for flyers, letterheads, and the inside pages of books. "Cover" (or Cardstock) is heavier and more rigid, making it ideal for business cards, postcards, and invitations. Cover stocks must be scored before folding to prevent cracking.
Gloss vs. Matte:
A
Gloss finish is shiny and reflective, which makes colors "pop" and is perfect for photography-heavy designs. A
Matte finish is flat and non-reflective, making it easier to read and providing a more subtle, professional elegance that is forgiving of fingerprints and smudges.
Understanding Weights (lbs vs. gsm):
North America uses pounds (# or lb), while the International system uses grams per square meter (gsm or g/m²). It is important to note that a 100lb Text stock is significantly thinner than a 100lb Cover stock because they are measured using different base ream sizes. Below is a comparison chart to help you understand the relative thickness of different stocks:
| US Weight (lb) | Metric (gsm) | Common Paper Grade |
|---|
| 20lb / 50lb | 75.2 g/m² | Bond / Offset (Standard Office Paper) |
| 24lb / 60lb | 90.3 g/m² | Bond / Text (Higher quality flyers) |
| 28lb / 70lb | 105.4 g/m² | Bond / Text (Premium brochures) |
| 80lb Text | 104.0 g/m² | Standard Gloss/Matte Book pages |
| 80lb Cover | 218.2 g/m² | Standard Postcard / Business Card |
| 100lb Cover | 270.9 g/m² | Heavy-duty Cardstock |
| 12 pt. | ~300 g/m² | Ultra-thick Premium Business Card |
Selecting the right combination ensures your project feels as good as it looks. If you are producing a high-end catalog, you might choose an 80lb Gloss Text for the inside pages and a 100lb Matte Cover for the outside to provide a durable, premium feel.
