What Weight is Card Stock Paper? Your Definitive Guide

Card stock, the stalwart of paper crafts, invitations, and professional presentations, isn’t defined by a single weight. Instead, it’s a range of paper weights, typically starting around 60 lb cover (163 gsm) and extending upwards to 120 lb cover (325 gsm) or even heavier. Understanding this range, and the differences between basis weights and GSM (grams per square meter), is crucial for choosing the right card stock for your project. This article will equip you with the knowledge to confidently navigate the world of card stock weights.

Deciphering Paper Weight: Basis Weight vs. GSM

Before we dive into specific weights, let’s clarify the terminology that often confuses even experienced crafters and printers. The two main systems for measuring paper weight are basis weight and GSM (grams per square meter).

Basis Weight: This system measures the weight (in pounds) of a ream (500 sheets) of paper in its basic uncut size for that specific paper type. The catch? Different paper types have different basic sizes! So, 65 lb cover stock isn’t the same weight as 65 lb text stock. Cover stock, used for card stock, generally has a larger basic size than text stock. This is why you need to always specify “cover” or “text” when discussing basis weight.
GSM (Grams per Square Meter): This is an absolute measure of paper weight. It represents the actual weight of one square meter of the paper in grams. Unlike basis weight, GSM is consistent across all paper types. A 200 gsm paper will always have the same weight, regardless of whether it’s card stock, text paper, or something else.

In the card stock world, you’ll most commonly encounter lb cover weight (basis weight for cover stock) and GSM. Converting between the two can be tricky, but online calculators and charts are readily available.

Understanding Card Stock Weight Ranges

Now, let’s look at typical card stock weight ranges and their ideal uses:

60-65 lb Cover (163-176 gsm): This is considered the lightest weight card stock. It’s still noticeably thicker than standard printer paper, making it suitable for projects that require some durability without bulk. Think lightweight invitations, postcards, or layering in paper crafts.
80 lb Cover (216 gsm): A popular and versatile option, 80 lb card stock offers a good balance of thickness and affordability. It’s suitable for a wide range of projects, including greeting cards, invitations, presentations, and scrapbook pages.
90-100 lb Cover (243-270 gsm): Stepping up in thickness, these weights provide a more premium feel. They’re ideal for business cards, upscale invitations, and projects that demand a sturdier material.
110 lb Cover (300 gsm): This is a substantial card stock that offers excellent rigidity and durability. It’s perfect for high-end business cards, premium invitations, and presentation folders.
120 lb Cover (325 gsm) and Heavier: These are the heavyweights of the card stock world. They provide exceptional stiffness and a luxurious feel. Common uses include hang tags, product packaging, and specialty projects where durability is paramount.

Choosing the Right Weight: Factors to Consider

Selecting the perfect card stock weight hinges on several factors:

Project Type: What are you making? An invitation requires a different weight than a hang tag.
Desired Feel: Do you want a lightweight, flexible feel, or a rigid, substantial one?
Printing Method: Some printers struggle with very heavy card stock. Check your printer’s specifications.
Budget: Heavier card stock generally costs more.
Ink Coverage: Heavy ink coverage can cause lighter card stock to warp or bleed.
Embellishments: If you plan to add embellishments like ribbons, gems, or brads, a heavier card stock will provide better support.

Frequently Asked Questions (FAQs) about Card Stock Weight

1. What is the difference between card stock and paper?

The primary difference lies in weight and thickness. Card stock is significantly heavier and thicker than standard printer paper (often called text paper). This makes it more durable and suitable for projects that require rigidity and longevity. Standard paper is typically around 20 lb bond (75 gsm), while card stock starts at around 60 lb cover (163 gsm).

2. What weight is standard printer paper?

Standard printer paper is typically 20 lb bond weight (sometimes called “text” or “writing” weight), which corresponds to approximately 75 gsm. It is designed for everyday printing tasks and not for projects requiring durability.

3. Can I print on card stock with my home printer?

Yes, but check your printer’s specifications. Most inkjet and laser printers can handle card stock up to a certain weight, typically around 80 lb cover (216 gsm). Heavier card stock may cause paper jams or feeding problems. Always consult your printer manual for its recommended paper weights.

4. What does “cover stock” mean?

“Cover stock” refers to a type of paper that’s heavier and more durable than text or bond paper. It’s designed for covers of books, brochures, business cards, and other applications where a thicker, more rigid material is needed. The term “cover” refers to its primary function – covering other materials.

5. Is 65 lb card stock thick enough for invitations?

Yes, 65 lb card stock can be suitable for lightweight or casual invitations. However, for a more premium feel, 80 lb or heavier card stock is generally preferred. Consider the overall aesthetic you’re aiming for and the amount of handling the invitations will endure.

6. What weight card stock is best for business cards?

90-110 lb cover (243-300 gsm) is generally considered the best weight for business cards. This range provides a professional feel, durability, and prevents the cards from feeling flimsy. For a truly luxurious card, you can even go heavier.

7. How do I convert between lb cover weight and GSM?

While there’s no exact formula due to slight variations in manufacturing, a good rule of thumb is to use an online converter. Search for “paper weight conversion calculator” to find a reliable tool. Remember that the conversion is an approximation.

8. What is the thickest card stock available?

The thickest commercially available card stock can range upwards of 130 lb cover (350 gsm) and beyond. Some specialty papers, like chipboard or mount board, can be significantly thicker, but they aren’t typically considered card stock in the traditional sense.

9. Can I use card stock in my die-cutting machine?

Yes, you can use card stock in a die-cutting machine. The weight of the card stock will affect how easily it cuts and the quality of the cut. Lighter card stock is easier to cut, while heavier card stock may require more pressure or multiple passes.

10. Does the finish of card stock affect its perceived weight?

Yes, the finish can influence how heavy card stock feels. A coated or glossy finish can make the card stock feel slightly more substantial than an uncoated finish of the same weight. This is because the coating adds a thin layer of material to the surface.

11. Where can I buy card stock in different weights?

Card stock is widely available at craft stores, office supply stores, and online retailers such as Amazon. Many local print shops also carry a variety of card stock weights and finishes.

12. Is it possible to recycle card stock?

Yes, most card stock is recyclable, as long as it’s not heavily embellished with non-paper materials like glitter or plastic. Check with your local recycling program to confirm their specific guidelines.
