US Paper Naming: lb, pt, and GSM Explained

Paper in the US has two naming systems — pounds (lb #) and points (pt). Other countries use weight (GSM). This confuses almost everyone. This page explains how the systems compare, lists every paper stock we offer with its specifications, and recommends the right paper for each type of printed piece.

Page Summary — This page explains how U.S. printing paper is measured and compared, including lb, pt, GSM, common equivalencies, synthetic stocks, and paper size standards, with tools and charts to help non-experts choose the right paper; quick answers include standard copy paper = 20lb bond, business cards = 14pt or 100lb cover, flyers = 60–80lb text, brochures = 100lb gloss text, and menus = 80lb cover or synthetic waterproof.

How US Paper Weight Works (Basis Weight)

The short version: Paper is weighed in batches of 500 sheets at the factory, before cutting. That batch weight becomes the paper's name. Because different paper types are cut from different factory-size sheets, the same physical paper can carry two different pound numbers depending on where it was made.

Why 20lb bond and 50lb text are the same paper

Bond paper is factory-cut from 17"×22" sheets. Text paper from 25"×38" sheets. The same physical paper run through both lines: Bond version = 20lb, text version = 50lb. Same paper, two names. The Equivalency Chart later on this page shows every cross-family match.

Index25½" × 30½"Postcards, index cards, dividers90lb, 110lb, 140lb

What Does "pt" (Point) Mean?

Cardstock is often measured in points (pt). One point = 0.001 inch. So 14pt cardstock = 0.014" thick. This system is common for business cards, menus, postcards, and book covers — and it's entirely separate from the lb system.

8pt0.008"~65lb~177Light postcards, rack cards
10pt0.010"~80lb~218Postcards, greeting cards

Side-by-side thickness comparison of 80lb gloss text vs 100lb gloss text paper — though both share the same family, 100lb is noticeably thicker and stiffer, demonstrating that the lb number does reflect a real physical difference within a paper family
Paper thickness matters: The name of the papers does not reflect the thickness. Tis image shows the height of a pile of 1000 sheets of 80lb of different types of paper.
14pt ≈ 100lb cover. Note that lb (weight) and pt (caliper/thickness) measure different things — so their GSM values differ: 100lb cover ≈ 270 GSM, while 14pt ≈ 306 GSM. In practice they're sold as equivalent grades for business cards, but the underlying GSM values differ because lb measures basis weight while pt measures caliper.

80lb vs 100lb Paper — What's the Difference?

The answer depends on which family you're comparing. Text and Cover paper share pound numbers but are very different sheets.

PaperGSMFeelBest For
80lb Gloss Text118Light, flexibleSingle-sheet flyers, inserts
100lb Gloss Text ✓148Solid, premiumBrochures, booklet pages, menus
80lb Cover216Stiff cardPostcards, rack cards, light covers
100lb Cover ✓270Very stiff cardstockBusiness cards, premium covers
Key distinction: Text vs. Cover

80lb cover is nearly twice as thick as 80lb text — even though they share the same number. For brochures, choose text. For brochures, choose text. For business cards and postcards, choose cover. The project-by-project paper guide earlier on this page recommends the right weight for each common use.

Paper Grades & Finishes

Paper "grade" describes what it's designed to do. Click any grade to expand.

A clay layer on the paper surface holds ink in a finer dot — producing sharper images and more vibrant color. Use coated paper whenever color quality matters.

  • Gloss — High shine. Colors pop. Best for photos and marketing materials.
  • Satin / Silk — Slight sheen, less glare. Popular all-around brochure choice.
  • Dull / Matte — No shine, easy to read. Great for menus and text-heavy pieces.
  • Cast Coated — Mirror-like finish. Luxury packaging and premium business cards.
For restaurant menus: Gloss looks great but shows fingerprints. Dull/matte hides smudges. Synthetic waterproof paper is best for frequently handled menus.
Matte coated vs. uncoated — not the same thing: Matte and dull-coated papers are often mistaken for uncoated because they have no visible shine. The difference: matte paper still has a clay coating — calendered to a flat finish instead of glossy. That coating means ink sits on the surface (sharper dot, more vivid color) rather than absorbing into the fiber. Uncoated paper has no clay layer at all. Quick test: if you can write on it cleanly with a ballpoint pen without smearing, it's uncoated. If ink beads slightly or feels smooth to the touch, it's matte coated.

No clay layer — ink absorbs into the fibers for a natural feel. Great for text-heavy documents, forms, and anything that will be written on. Available in smooth, vellum, laid, and linen textures. Common weights: 50–80lb text (same as 20–32lb bond).

Bond paper stays flat, takes pen and pencil well, and feeds reliably through office laser printers. Standard copy paper is 20lb bond. Premium letterhead is 24–32lb bond. Cotton-content bond (25% or 100%) is used for legal documents and diplomas — tear-resistant and ages better.

Thick, stiff paper where rigidity matters. Can be coated (gloss/matte) or uncoated. Measured in both lb cover and pt (points).

  • 65lb cover / 8pt — Light cardstock, greeting cards
  • 80lb cover / 10pt — Postcards, rack cards
  • 100lb cover / 14pt — Standard business card, brochure covers
  • 130lb cover / 16pt — Ultra-thick business cards, heavy-duty covers

Brightness (0–100 scale) measures how much blue-spectrum light the paper reflects. Higher = whiter and more vivid-looking color.

  • 92 - Standard Copy Print Paper — The most common 20lb and 24lb copy paper's brightness. Soft white tone, easy on the eyes for long reading. Best for drafts, internal notes, handouts where the message matters more than an upscale look.
  • 96 - Client Preferred — Cleaner white with crisp color accents. The sweet spot for client proposals, reports, premium handouts. Better opacity.
  • 100 - Marketing Impact — These specialty papers make colors pop. This brightness feel very upscale.
  • Below 86 - Cream / off-white — Typical for recycled or unbleached papers. Great for natural aesthetics, not ideal for photo printing.
Educational infographic titled 'Brightness and Whiteness: The Science of Paper Contrast.' Top row illustrates three concepts: paper fibers reflecting blue light, a warm-versus-cool white fiber comparison, and a vivid printed flower image demonstrating color pop. Bottom row shows three brightness tiers with sample printed pieces — 92 Bright for internal drafts and notes, 96 Bright for client proposals and reports, and 100 Bright for marketing flyers and photos.
Brightness measures how much light a paper reflects (driving text-to-paper contrast and color pop), while whiteness defines whether the sheet looks warm-cream or cool-blue. Most everyday office paper sits in the 92–96 range; 100-bright stocks are typically reserved for marketing pieces where maximum color saturation matters.

Synthetic (Waterproof) Paper — a Different Category Entirely

Synthetic paper is not paper at all — it's an extruded polypropylene film manufactured to look and print like paper. It is completely waterproof, tear-resistant, and wipe-clean, which makes it the preferred material for restaurant menus, outdoor signage, field-use documents, and any printed piece that will be handled repeatedly or exposed to moisture.

Key properties of synthetic paper
  • Waterproof: Does not absorb water, grease, or liquids. Wipes clean with a damp cloth.
  • Tear-resistant: Will not rip or fray at the edges under normal handling.
  • Maximum print size: Because it is an extruded film, the maximum sheet size is 13"×19". It can be trimmed to any smaller custom size.
  • Available thicknesses: Multiple caliper options are available — thicker for covers and menus, thinner for inserts and overlays. See the product page for current thickness options.
  • Printing: Prints with high color fidelity on laser digital presses. Color accuracy and vibrancy are similar to coated paper.
  • Not weight-rated: Synthetic paper is specified by caliper (mil or pt), not by lb or GSM. The lb-to-GSM equivalency tables for traditional paper do not apply to synthetic substrates because synthetic is an extruded polypropylene film, not a fiber-based paper.
Best for: Restaurant menus, outdoor event signs, wristbands, waterfront and marine applications, field reference cards, pool/spa menus, spiral-bound booklets used in food service or hospitality. Learn more about synthetic paper printing →

What is 14pt cardstock in pounds?
14pt is sold as approximately 100lb cover stock, though they measure different properties: lb measures weight, pt measures caliper (thickness). 14pt cardstock has a caliper of 0.014" and a GSM of approximately 306. It's the standard business card weight — solid professional feel, fits in a wallet.
What is the difference between 80lb text and 80lb cover?
80lb text (118 GSM) is thin and flexible — good for flyers and brochure pages. 80lb cover (216 GSM) is thick stiff cardstock, nearly twice as thick. Always specify text or cover when ordering.
What paper should I use for a restaurant menu?
For frequently handled menus: synthetic waterproof paper — wipes clean, will not tear or absorb grease. For laminated menus: 100lb gloss text or 80lb cover. For a spiral-bound menu booklet: 80lb gloss text inside, 100lb cover front and back.
What does GSM mean?
Grams per Square Meter — the international way to measure paper weight. Unlike US lb weights, GSM always measures the same area regardless of manufacturing origin, making it universally comparable. Common conversions: 20lb bond ≈ 75 GSM, 100lb gloss text ≈ 148 GSM, 14pt cardstock ≈ 306 GSM.
What paper does ColorCopiesUSA use for color copies?
Our standard color copies are on 20lb bond (75 GSM). We also offer 60lb and 80lb uncoated text, 100lb gloss text, and 80lb and 100lb cover. Choose your paper when you order color copies.
