Point size, pound cover and GSM lined up in one conversion table, plus how cardstock compares to cover stock, photo paper and laser sheets.
Cardstock is a heavyweight, stiff paper made for pieces that need to hold their own shape, such as business cards, postcards, folders and invitations, rather than lie flat inside a book or letter. In the print trade it falls in the cover weight category, generally somewhere between 65 lb cover and 140 lb cover, or roughly 175 gsm to 380 gsm, and its thickness is most often specified in points (a point equals one thousandth of an inch). The heavier the number, the stiffer and more substantial the sheet feels in hand.
Cardstock is not a single formula or a single mill's product. It is a category, defined more by caliper and stiffness than by one exact weight. Anything thick enough to stand up to handling on its own, a business card, a postcard, a folder cover, a table tent, a greeting card, gets sold as cardstock. Inside a commercial print shop the same material is usually called cover stock, which is the trade term for the same weight class. Cardstock can be coated or uncoated, bright white or natural, virgin fiber or recycled, and it comes in finishes ranging from high gloss to soft touch. What ties the category together is thickness and rigidity, not a particular look or coating.
Point size is the most common way the trade specifies cardstock thickness. A point equals one thousandth of an inch measured with a micrometer, so 12 pt stock is 0.012 inches thick and 16 pt stock is 0.016 inches thick. Most stocked cardstock in commercial printing runs from 10 pt to 16 pt, with 12 pt and 14 pt covering the bulk of business cards, postcards and folder covers ordered every week.
Point size, pound weight and GSM measure different things. Point caliper is a direct measurement of physical thickness. Pound cover weight is the weight of 500 sheets cut to the cover parent sheet size, which is a basis weight, not a thickness measurement. GSM, grams per square meter, is a true weight per area and the most consistent unit across mills. Because caliper and basis weight are measured differently, the same point size can land at a slightly different pound or GSM figure depending on the paper mill, the fiber blend and the coating. The ranges below are accurate representations of what you will see quoted across major mills, not a single fixed formula, so treat any point to pound conversion as a close range rather than an exact figure.
| Point (caliper) | Lb cover (approx.) | GSM (approx.) | Feels like |
|---|---|---|---|
| 8 pt | ~60 to 65 lb cover | ~165 to 180 gsm | Light card, the weight of a reply card or index card, still some flex in the sheet |
| 10 pt | ~70 to 80 lb cover | ~190 to 215 gsm | Standard postcard and lighter folder stock, firm and holds a crease well |
| 12 pt | ~80 to 100 lb cover | ~215 to 270 gsm | Common business card and postcard weight, sturdy with a confident hand feel |
| 14 pt | ~100 to 115 lb cover | ~270 to 310 gsm | The commercial default for business cards and premium postcards, noticeably stiffer than 12 pt |
| 16 pt | ~120 to 130 lb cover | ~325 to 355 gsm | Heavy premium cards and presentation folders, near the ceiling for many digital presses |
| 18 pt | ~140 to 150 lb cover | ~380 to 405 gsm | Rigid, tag like stock used for hang tags and thick invitations |
| 24 pt | ~180 to 200 lb cover | ~490 to 540 gsm | Board like rigidity, approaching the thickness of thin chipboard |
A quick sanity check on the "how many pounds is cardstock" question: 110 lb cover cardstock sits inside the 14 pt row above, so figure roughly 295 to 300 gsm. A 250 gsm cardstock sheet lands between the 10 pt and 12 pt rows, so figure roughly 90 to 95 lb cover. These are close estimates for planning a job, not a spec you should quote to a mill without confirming their own conversion chart.
This one has a simple, direct answer. In commercial printing, cardstock and cover stock are effectively the same material. Cover stock is the formal, trade side name for heavyweight sheets built to the cover parent sheet size, the category a paper mill or a press operator will use. Cardstock is the everyday, customer facing name for the same category, the word most people reach for when they mean a card or a folder that can stand up on its own. When you call Printing Partners and ask for cardstock, we will quote you cover stock, because that is the shelf it comes from. The nuance worth knowing is that "cover" tells you the weight class while "cardstock" is really describing the end use, so the two terms overlap almost completely but are not defined by identical criteria. You will occasionally see "cover stock" used for slightly heavier or more specialized sheets, such as cover stock built for offset packaging, while "cardstock" gets used more loosely for anything stiff enough to hold a shape.
A lot of the confusion around cardstock comes from comparing it to papers that sound similar but sit in a different category entirely. The table below lines up the stocks people ask us about most.
| Stock | Typical weight | Key difference from cardstock |
|---|---|---|
| Cardstock / cover stock | ~65 to 140 lb cover (175 to 380 gsm) | The baseline. Stiff, freestanding, coated or uncoated. |
| Laser or copy paper (80 lb, 100 lb) | 80 to 100 lb TEXT (118 to 148 gsm) | Text weight, not cover weight. An 80 lb or 100 lb text sheet is roughly half the thickness of a cardstock sheet carrying the same number, because text and cover are measured against different parent sheet sizes. |
| Glossy or matte photo paper | ~200 to 280 gsm | Built for photographic ink saturation and color depth on inkjet equipment, not for commercial press runs. It handles differently and is rarely stocked for offset or digital print jobs. |
| Coated cover (C1S / C2S) | Same range as cardstock | Not a separate weight category, just cardstock distinguished by which side carries the coating. |
The short version: if a spec sheet says "text" or "bond," it is a lighter, more flexible paper meant for pages inside a document. If it says "cover," it is cardstock by another name.
Weight tells you how thick the sheet is. Finish tells you how it looks and feels, and cardstock is available in nearly every finish Printing Partners stocks.
A shiny, reflective coating on both sides that makes color and photography pop. The most common finish for business cards and postcards that lead with a photo.
A flat, non reflective coating that reads as more sophisticated and is easier to write on or read under glare than gloss.
A soft sheen between gloss and matte, popular on premium cardstock where you want color pop without a mirror finish.
No coating on either side. Softer color, but the surface takes handwriting, rubber stamps and adhesive far better than a coated sheet.
Glossy or matte on the front, uncoated on the back. A common choice when the reverse needs to be written on or glued, such as folder inserts and packaging.
Coated front and back for sharp, saturated printing on both faces. The standard for double sided business cards and postcards.
A velvety, low sheen laminate applied over cardstock for a premium, tactile finish. We can quote soft touch lamination on request for folders, covers and presentation pieces.

Cardstock is the workhorse stock behind most of what leaves our Indianapolis facility. A few of the pieces we run on it every week:
Cardstock is a heavyweight paper category, technically classified as cover stock rather than text or bond weight. It typically runs from about 65 lb cover (8 pt) up to 130 lb cover (16 pt) or heavier, though the trade defines it more by stiffness and caliper than by a single weight. Cardstock can be coated, uncoated or specialty finished.
Most cardstock falls between 65 lb cover and 130 lb cover, or roughly 175 to 355 gsm. Lighter stock in that range, around 65 to 80 lb cover, is common for reply cards and lighter folders. Heavier stock, 100 lb cover and up, is standard for business cards and premium print pieces. Exact numbers vary by paper mill.
14 pt cardstock generally falls between 100 lb cover and 115 lb cover, roughly 270 to 310 gsm, depending on the paper mill and finish. The figure quoted most often for 14 pt is 114 lb cover, about 308 gsm. Point size measures physical thickness while pound weight measures basis weight, so the two scales do not convert with perfect precision. Treat any 14 pt to pound conversion as a close range, not an exact figure.
16 pt cardstock typically lands between 120 lb cover and 130 lb cover, or about 325 to 355 gsm. It is among the heaviest stock many digital presses can run, which is why 16 pt is the ceiling for premium business cards and presentation folders rather than a starting point.
In everyday language cardstock and cover stock describe the same material. Cover stock is the term used inside the print trade for heavyweight sheets built for covers, cards and folders, while cardstock is the word most customers use for the same category. When you ask a print shop for cardstock, they will quote you cover stock.
Not necessarily. An 80 lb or 100 lb laser paper is usually text weight, made for double sided printing through a laser printer and noticeably thinner than true cardstock. True cardstock is measured in cover weight, so 100 lb cover cardstock is roughly twice as thick as 100 lb text paper even though the pound numbers match.
C2S stands for coated two sides, meaning both faces carry a gloss or matte coating for sharp, saturated printing on both sides. Uncoated cardstock has no coating on either side, so it prints softer colors but takes handwriting, ink stamps and adhesive better. C1S falls in between, coated on one side only.
Printing Partners is FSC certified, so we can run cardstock carrying FSC chain of custody documentation. Recycled content varies by mill and by stock, and availability changes, so the specific recycled cover weight for your job is worth confirming before you spec it. Call 317-635-2282 and we will check what is available in the weight and finish you need.
Point size and GSM only tell you so much on a screen. Start with a quote and we will walk you through the cover weight and finish that suit the piece, the run length and the way it gets handled once it leaves here.
