What Is Cardstock Paper? Types, Weights, and Uses Explained

Cardstock is a heavyweight paper substrate ranging from 65 lb cover (176 gsm) to 110 lb cover (300 gsm) thick enough to hold its shape under handling, yet flexible enough to fold, score, and cut cleanly. It is the standard material for business cards, greeting cards, packaging, wedding invitations, and any print project where regular 20 lb copy paper would buckle, tear, or feel cheap.

The distinction matters immediately in practice. Hold a sheet of 80 lb cover cardstock at one corner and it stays flat. Do the same with standard office paper and it droops. That stiffness  measured as caliper  is what makes cardstock the default choice for commercial printers, graphic designers, and paper crafters alike.

What Is Cardstock Made Of?

Cardstock begins as cellulose wood pulp fibres compressed under heat and pressure into a dense sheet. The higher the fibre density, the heavier, stiffer, and more durable the final sheet.

Surface coatings are applied after the base sheet is formed. Manufacturers use kaolin clay or calcium carbonate to create smooth, glossy, or matte finishes. These coatings sit on top of the fibre layer and directly control how ink pigments are absorbed or held at the surface which determines color vibrancy, print sharpness, and drying time.

Uncoated cardstock skips this surface treatment entirely. Ink soaks into the fibres, which softens colour reproduction but makes the sheet receptive to writing, rubber stamping, and letterpress printing.

Cardstock vs Regular Paper: What Actually Differs?

The fundamental difference is basis weight. Standard copy paper is 20 lb bond (75 gsm). Cardstock starts at 65 lb cover (176 gsm) more than double the weight per sheet.

That weight difference produces three practical consequences. First, caliper: cardstock is physically thicker, typically 8 to 10 points (thousandths of an inch) for an 80 lb cover sheet, compared to roughly 4 points for copy paper. Second, rigidity: cardstock resists flexing under its own weight and holds flat during handling, printing, and repeated use. Third, moisture resistance: the denser fibre structure does not buckle when exposed to humidity, making cardstock reliable for products like restaurant menus and outdoor signage that regular paper would ruin.

For print professionals, this also means ink sits differently on each substrate. On coated cardstock, pigments remain at the surface, producing sharper dot gain and richer colour. On copy paper, pigments spread into the fibres, softening edges and reducing colour saturation.

Cover Stock vs Cardstock: Is There a Real Difference?

No. The terms refer to the same material category. Cover stock sometimes written as coverstock is the trade term used by commercial printers, paper mills, and print buyers. Cardstock is the retail term used by craft stores, office supply chains, and consumer packaging.

When a commercial printer quotes a job on “100 lb cover,” that sheet is identical to what a craft retailer sells labelled as “heavyweight cardstock.” The difference is purely nomenclature based on who is buying and in what context.

Pasteboard is a third term for the same material, used primarily in traditional bookbinding and archival contexts where stiff cover sheets form the structural shell of a bound volume.

Cardstock Weight and Thickness: How the Numbers Work

Weight labelling confuses buyers because the US and international systems use incompatible logic.

In the United States, basis weight measures the weight in pounds of 500 sheets cut to a standard parent size. The problem is that different paper categories use different parent sizes. Cover stock uses a 20 × 26 inch sheet. Text stock uses a 25 × 38 inch sheet. This is why 80 lb cover feels dramatically heavier and stiffer than 80 lb text, even though both carry the same number the 500 sheets being weighed are cut to different dimensions.

The ISO gsm system (grams per square metre) eliminates this confusion. It measures the weight of one square metre of any sheet, regardless of category, making direct comparisons straightforward. A sheet labelled 216 gsm is 216 gsm whether it is classified as cover, text, or bond.

Common Cardstock Weights at a Glance

Caliper matters when a finished product must fit inside a standard envelope or a slot-based display holder. A greeting card printed on 100 lb cover may not seat properly in an A2 envelope sized for 80 lb stock.

Types of Cardstock: Texture, Finish, Size, and Colour

Cardstock is not one material. It is a broad category that varies across four independent dimensions.

By Texture

• Smooth cardstock has a uniform, flat surface with no visible fibre pattern. It is the standard choice for inkjet and laser printing where sharp text and photographic image reproduction matter most.
• Laid cardstock carries a subtle ribbed pattern created during manufacturing by pressing the wet pulp sheet against a wire mesh roller. The result is a series of parallel lines visible at an angle. Laid finish is associated with formal correspondence, legal certificates, and letterpress printing, where the texture adds visual authority.
• Linen cardstock replicates the woven appearance of linen fabric through an embossing process applied after the base sheet is formed. It is the most common premium texture for wedding invitations and professional business stationery, because the pattern reads as hand-crafted without compromising print quality.
• Felt cardstock has a softer, slightly napped surface produced by pressing felt fibres against the sheet during manufacturing. It is typically reserved for luxury brand packaging and high-end stationery where tactile impression at first touch is a deliberate design decision.
• Embossed cardstock carries a raised or recessed geometric or decorative pattern pressed into the surface with metal dies after the sheet is formed. The three-dimensional surface adds visual depth and is common in premium wedding suites and branded gift packaging.
• Vellum cardstock is a semi-translucent, smooth sheet that allows underlying colours and patterns to show through. In layered invitation suites, a vellum overlay printed with guest names sits over a coloured base card. In scrapbooking, vellum is used as a journaling surface over photographs.

By Finish

The coating applied or not applied  to the base sheet determines how light reflects off the surface and how ink behaves during printing.

• Glossy finish has a high-sheen resin coating that reflects light uniformly, intensifying colour saturation and giving photographic prints a polished, vivid appearance. Postcards, retail brochures, and product flyers printed on glossy cardstock read as vibrant and professional. The trade-off is that gloss surfaces show fingerprints and are harder to write on.
• Matte finish has a diffusing coating that scatters light rather than reflecting it. Text is easier to read on matte stock because there is no glare. Colour reproduction is slightly flatter than gloss, but the overall impression reads as refined rather than flashy. Business cards, book covers, and corporate stationery overwhelmingly favour matte.
• Satin or silk finish sits between the two. It carries a moderate sheen that improves colour reproduction beyond matte while maintaining enough surface diffusion for comfortable text legibility. Multi-page brochures and magazine covers often use satin stock precisely because it handles both image reproduction and body text well simultaneously.
• Uncoated cardstock has no surface treatment at all. Ink penetrates the fibres directly. This reduces colour saturation and sharpness compared to coated stocks, but makes the sheet ideal for letterpress printing, rubber stamping, and handwriting all of which require the ink to grip the surface rather than sit on top of it.

By Size

Standard cardstock sizes match standard paper dimensions: Letter (8.5 × 11 inches) for US home and office printers, A4 (210 × 297 mm) for international use, and Legal (8.5 × 14 inches) for folded brochures and legal documents. The 12 × 12 inch format is dominant in scrapbooking and paper crafting, where the square format accommodates standard photo layouts without trimming.

Commercial printers use oversized parent sheets typically 23 × 35 inches and cut them down using guillotine cutters or rotary trimmers after printing, which allows precise bleed margins and multiple pieces from a single press run.

By Colour and Specialty Finish

Beyond white and off-white, cardstock is produced in a full solid-colour spectrum and a range of specialty substrates.

Kraft cardstock is a brown, uncoated sheet made from recycled or minimally processed wood pulp. Its natural, unfinished aesthetic makes it the default material for hang tags, eco-conscious packaging, and rustic stationery. Brands like Tobacco Road and Neenah Environment produce kraft cardstock lines used commercially.

Metallic cardstock is coated with a foil-effect layer in gold, silver, copper, or gunmetal. Unlike foil stamping  which is a separate post-press process  metallic cardstock carries its finish across the entire sheet and prints directly through standard digital presses.

Pearlescent cardstock contains mica particles suspended in the coating layer, creating a soft iridescent shimmer that shifts colour slightly under different light angles. It is common in luxury wedding invitations and premium cosmetic packaging.

Eco-Friendly Cardstock: Sustainable Options That Meet Print Standards

Environmental credentials are now a procurement requirement for many brands, not just a preference. Several sustainable cardstock lines perform comparably to virgin fibre stock on press.

FSC-certified cardstock is produced from wood pulp sourced from forests audited by the Forest Stewardship Council. The FSC chain-of-custody certification covers every stage from harvest to finished sheet. Mohawk Fine Papers and Neenah Paper both carry FSC-certified lines stocked by most commercial trade printers.

Recycled cardstock is manufactured using post-consumer waste (PCW) paper collected after the end of its first use cycle. PCW content is expressed as a percentage — 30%, 50%, or 100% PCW. Modern recycled grades from French Paper Company and Cascades Rolland achieve brightness and smoothness levels close to virgin fibre, eliminating the performance gap that once made recycled stock a compromise.

Sugarcane (bagasse) cardstock replaces wood pulp entirely with agricultural residue from sugarcane processing. Because bagasse is a waste product of sugar production, it reduces pressure on forest resources without requiring dedicated cultivation. It is increasingly available through speciality paper merchants for brands with aggressive sustainability targets.

What Is Cardstock Used For? Professional Applications by Weight

The correct weight selection for a given application is not subjective — it follows established industry practice driven by function, handling expectations, and printer compatibility.

• Business cards are printed on 14 pt to 16 pt stock, which corresponds roughly to 100 lb to 110 lb cover. At this weight, the card resists bending in a wallet and conveys the tactile quality associated with professional credibility. Research in print marketing consistently shows that heavier card weight increases perceived brand quality at first contact.
• Greeting cards and postcards use 80 lb cover (216 gsm) as the industry standard. At this weight, a folded A2 greeting card seats cleanly in a standard envelope without excess bulk, and a flat 4 × 6 inch postcard meets USPS weight and rigidity requirements for standard postage.
• Wedding invitations and formal event stationery are typically printed on 100 lb cover in linen or cotton-blend stocks. The combination of weight and texture communicates formality and sets recipient expectations before the invitation is read.
• Folding cartons and retail packaging require 80 lb to 110 lb cover depending on the box dimensions and what the package must support structurally. Cardstock in this application must fold cleanly along score lines, hold its shape on a retail shelf, and accept print without surface cracking at the fold.
• Brochures and flyers are commonly printed on 80 lb to 100 lb gloss or matte cover, heavy enough to feel substantial in hand but light enough to mail cost-effectively in flat or folded formats.
• Certificates and diplomas are typically produced on 80 lb uncoated laid or linen stock. The textured, uncoated surface is both conventional for formal documents and practical for signatures applied after printing.
• Restaurant menus use heavy coated cardstock  often laminated  because the surface must resist repeated handling, moisture, and cleaning. In practice, a menu that survives a hospitality service environment is typically 100 lb cover with a matte or gloss laminate overlay.

What Can You Make with Cardstock? Craft and DIY Applications

In the paper crafting market, cardstock is the structural foundation of almost every handmade project. The material properties that make it useful professionally rigidity, clean-cut edges, printability — translate directly into craft applications.

Card making centres on cardstock as the card blank itself. A standard A2 card blank is cut from an 8.5 × 11 sheet of 80 lb cover, scored at the centre, and folded. Decorative elements — die-cuts, stamped panels, punched shapes are layered on top using adhesive. The base layer must be stiff enough to hold dimension without buckling under the adhesive weight of multiple layers.

Scrapbooking uses 12 × 12 inch cardstock sheets as page backgrounds, photo mats, and journaling blocks. Paper packs bundling 20 to 60 coordinated colours are sold specifically for this format by retailers including Stampin’ Up!, American Crafts, and DCWV.

Paper flowers and three-dimensional embellishments are cut from cardstock using Cricut Maker or Silhouette Cameo die-cutting machines. The stiffness of cardstock — compared to text-weight paper — allows cut petal shapes to hold their curl and form after shaping by hand. At 65 lb to 80 lb cover, the material flexes enough to shape without cracking.

Packaging templates for custom boxes, envelopes, and product sleeves are printable from home on Letter or A4 sheets of 80 lb to 100 lb cardstock. The score-fold-assemble workflow requires no adhesive for simple tuck-end box formats.

How to Print on Cardstock: Inkjet, Laser, and Commercial Presses

Most desktop inkjet printers handle cardstock up to 80 lb cover (216 gsm) through standard paper trays. Sheets heavier than 100 lb cover (270 gsm) typically require a straight paper path available on select Epson EcoTank and Canon PIXMA Pro models to prevent the sheet from jamming on the curve inside the paper transport mechanism.

Always verify the maximum gsm rating listed in your printer’s technical specifications before loading heavy stock. Epson, Canon, and HP publish these limits in both the physical printer manual and on their product support pages.

For inkjet printing on uncoated cardstock, total ink coverage is the critical variable. Heavy coverage — dark backgrounds, full-bleed photographic images — deposits more liquid ink than an absorbent uncoated surface can cure quickly. The result is surface cockling (buckling) and slow drying. Reducing total ink coverage to 250% or below in your RIP or print driver settings prevents this on absorbent stocks.

Practical settings for home and office printers:

Load sheets one at a time through the manual bypass tray, not the main paper cassette. Select “cardstock,” “heavy paper,” or “thick paper” in the printer driver media type settings — this adjusts the fuser temperature on laser printers and slows the feed rate on inkjets, both of which improve output quality on heavier stocks. Allow inkjet prints to dry for at least 30 seconds before stacking, as denser coatings extend cure time.

For high-volume professional runs, laser printers including the Xerox Versalink and Konica Minolta Bizhub series — bond toner to coated cardstock more consistently than inkjet ink, and do not require extended drying time.

Commercial print shops use offset lithography presses or digital presses including the HP Indigo 7K and Xerox iGen 5, which are factory-calibrated to handle cardstock across the full weight range at production speeds. Offset printing on cardstock achieves colour accuracy and surface quality that desktop printers cannot replicate.

Benefits of Cardstock Over Regular Paper

The advantages of cardstock are not aesthetic preferences they are direct consequences of material properties.

• Durability is the primary functional benefit. The higher fibre density of cardstock resists tearing, moisture absorption, and edge degradation through repeated handling. A business card printed on 16 pt stock survives months of wallet contact without visible wear. The same card printed on 80 lb text paper would develop edge fraying and surface scuffing within weeks.
• Print quality on coated cardstock exceeds what is achievable on copy paper because the coating layer holds ink pigments at the surface rather than allowing them to diffuse into the fibre. The result is sharper dot reproduction, richer colour density, and higher contrast particularly visible in photographic images and fine typography.
• Structural rigidity allows folded and assembled products greeting cards, brochures, folding cartons to maintain their intended shape during shipping, retail display, and consumer handling. A brochure printed on copy paper loses its structure the moment it is picked up. The same content on 80 lb cover holds its fold and reads as intentionally designed.
• Professional perception is measurable, not assumed. Studies in direct mail marketing have demonstrated that heavier paper stock increases the perceived value of printed communications and improves response rates. In the case of business cards, the haptic weight and surface finish of the card stock are processed by recipients before the content is read  a direct influence on first impression.

FAQs

Is cardstock the same as construction paper?

No. Construction paper weighs 50 lb to 60 lb text  lighter than the lightest cardstock — and uses low-grade uncoated fibre that fades rapidly under light exposure. It is not designed for printing and does not hold clean cut edges under die-cutting. Cardstock is a higher-grade substrate designed specifically for print quality, durability, and structural performance.

Can you run cardstock through a Cricut or Silhouette machine?

Yes. Both the Cricut Maker 3 and Silhouette Cameo 4 are rated for cardstock up to 100 lb cover. Heavier weights or specialty finishes — metallic, embossed, or laminated stock — may require a deeper blade offset setting or a second cut pass to achieve a clean edge.

What is the best cardstock weight for greeting cards?

80 lb cover (216 gsm) is the commercial standard for folded greeting cards. It scores and folds cleanly without cracking the surface coating, holds its shape after folding, and fits standard A2 and A6 envelopes without creating excess bulk at the folded spine.

What is the difference between cardstock and cardboard?

Cardstock is a single-ply cellulose sheet up to approximately 110 lb cover (300 gsm). Cardboard also called paperboard or boxboard — is constructed from multiple plies bonded together, or from a corrugated flute layer sandwiched between two flat liner sheets. Cardboard begins structurally where cardstock ends, and is used for shipping cartons and structural retail packaging rather than print-quality applications.

What is the difference between cardstock and photo paper?

Photo paper is engineered specifically for inkjet photographic printing, with a resin coating optimised for maximum colour gamut and surface gloss. Cardstock is a structural substrate that accepts printing as a secondary function. Glossy cardstock and photo paper may look similar, but photo paper prioritises image fidelity over rigidity, while cardstock prioritises structural performance over photographic colour accuracy.
