In crafts and printing, thick paper is usually called cardstock. You’ll also see it listed as cover stock or heavyweight paper. On this page, cardstock comes in a range of thicknesses—commonly 65 lb, 80 lb, 100 lb, 110 lb, and even 130 lb (often shown as GSM too). Finishes and colors vary, including smooth, linen-textured, kraft, bright white, cream, metallic, glitter, and assorted colors. Sizes span small cards (4x6, 5x7) to standard sheets (8.5x11), legal, tabloid, square (12x12), and more. It’s a versatile pick for invitations, DIY cards, scrapbooking, menus, and presentation pieces.

Common alternatives include cover stock, index card stock, and heavyweight paper. You may also see C1S (coated one side) for glossy or smooth printing on a single side, as well as mixed media paper when the sheet is designed to handle paints and inks. These terms appear across the selection and often point to different finishes and uses—card making, signage, scrapbooking, or printer-friendly sheets. When you compare options, look at the listed weight (in lb, GSM, or points) and the finish (smooth, linen, glitter, metallic, kraft) to match your project.

Thickness is typically indicated by GSM (grams per square meter), cover weight (lb), or points (pt). Higher numbers generally mean a stiffer, thicker sheet. In this assortment, some of the thickest options reach 24 pt / around 520 GSM, with other heavy picks in the 110–130 lb cover range. You’ll also find specialty finishes like glitter and metallic stocks that can feel especially rigid. If maximum sturdiness is your goal, check the product details for the highest GSM or point values listed, keeping in mind what your tools and printer can handle.

If you’re after maximum rigidity, consider heavy cover stocks listed around 110–130 lb, or sheets noted in points and GSM up to 24 pt / ~520 GSM in this category. The right choice depends on how you’ll use it:

• Printing: Check your printer’s supported media types and weights. Many home printers handle medium weights, while heavier sheets may require specialty settings or manual feed.
• Crafting: For die-cutting, displays, or sturdy cards, heavier stocks can provide a firmer feel.
• Finish: Smooth, linen, glitter, or coated-one-side (C1S) surfaces may behave differently with ink and adhesives.

Matching weight, finish, and size to your project can help you get the feel you want.

Choose a size that fits your project and tools:

• 4x6 and 5x7: Handy for postcards, invitations, and small greeting cards.
• 8.5x11 (Letter): Template-friendly and widely supported by home printers.
• 8.5x14 (Legal) and 11x17 (Tabloid): Useful for menus, larger prints, or pieces you’ll fold.
• 12x12: Popular for scrapbooking and square projects.
• A4: Works for international templates and some cutting patterns.

Also consider weight and finish (smooth, linen, glitter, metallic, kraft) for your design, and confirm your printer or cutting tools support the size and thickness you plan to use.
