What Is Cover Stock?
Cover stock is a thick, rigid paper designed to protect and present printed work. Unlike standard writing or text paper, cover stock has a higher basis weight and a stiffer feel, which makes it ideal for book jackets, postcards, business cards, and product packaging. The term refers to the paper itself, not a specific finish, so cover stock comes in a range of textures, colors, and coatings that designers can mix and match.

Common Weights and Thicknesses
Cover stock is typically measured in pounds (lb) or points (pt), with higher numbers indicating a heavier, stiffer sheet. The right weight depends on the project's durability needs and how it will be handled.
| Weight (lb) | Thickness (pt) | Typical Use |
|---|---|---|
| 60–80 lb | 10–14 pt | Lightweight postcards, thin brochures |
| 80–100 lb | 14–18 pt | Standard book covers, invitation cards |
| 100–120 lb | 18–24 pt | Premium book covers, game boards |
| 120+ lb | 24+ pt | Heavy-duty packaging, display stands |
Finishes and Coatings
The surface of cover stock changes how it looks and feels. A smooth, coated stock holds crisp text and sharp images, while an uncoated stock absorbs ink more softly and gives a tactile, organic quality. Common finishes include matte, gloss, satin, and linen, each offering a different level of sheen and grip.
- Matte — non-reflective, easy to write on, modern feel
- Gloss — high shine, vibrant color reproduction
- Satin — a middle ground between matte and gloss
- Linen or textured — adds a tactile, premium impression
How to Choose the Right Cover Stock
Start with the project's purpose. A book cover that will sit on a shelf needs enough stiffness to resist warping, so 100 lb or heavier is a safe choice. A postcard meant to be mailed and handled frequently should be durable but not so thick that it jams mailing machines. Coatings matter too: a gloss finish protects against moisture and wear, while an uncoated stock may be better for projects where a handwritten note or signature is expected.
Consider the printing method as well. Digital presses handle a wide range of cover stocks, but offset printing often delivers sharper detail on heavier sheets. If the project involves embossing, foil stamping, or die-cutting, a heavier stock provides the stability those finishes require.
Sustainability and Sourcing
Many printers now offer cover stock made from recycled fibers or certified sustainable sources. These stocks are available in a variety of weights and finishes, so eco-conscious choices do not have to sacrifice quality. When sourcing, ask your printer for the stock's composition and whether it is FSC-certified or contains post-consumer waste.
Practical Tips for Designers
- Always request a sample before committing to a large print run — the feel of the stock influences the reader's first impression.
- Account for the spine width when choosing book cover stock; thicker stacks of pages require a sturdier cover to maintain a professional look.
- Test print a proof on the chosen stock to check color accuracy, as coated and uncoated surfaces render ink differently.
- Consider binding methods: perfect-bound books need a cover stock that can fold and adhere without cracking.
