This is the single most common source of confusion in printing, and it catches professionals as often as first-timers.

Someone orders "100-pound paper" and expects something thick and sturdy. What arrives is thin, floppy, and nothing like what they imagined. The problem isn't the printer. It's that 100# text and 100# cover are two completely different products — and the number alone tells you almost nothing.

How paper weight works (and why it's confusing)

Paper weight in the US is measured by the weight of 500 sheets at a paper's basis size. The catch: text stock and cover stock have different basis sizes.

Text stock is weighed at 25×38 inches.
Cover stock is weighed at 20×26 inches.

So when you see "100# text," that means 500 sheets at 25×38 inches weigh 100 pounds. When you see "100# cover," that means 500 sheets at the smaller 20×26 size weigh 100 pounds. The cover sheet is much thicker — it weighs the same as the text sheet despite being cut from a smaller basis size.

The number is the same, but the paper is not.

What they actually feel like

Here's a practical comparison:

100# text — Similar to a page in a nice magazine. Substantial enough to feel quality, but it bends easily. You'd use this for booklet interiors, flyers, or anything that needs to fold.
100# cover — Proper cardstock. Stiff, snaps if you try to fold it without scoring. This is what you want for business cards, postcards, and book covers.

If you've ever held a business card that felt flimsy, there's a good chance it was printed on text stock instead of cover.

The weights we use most

For most jobs, we reach for these:

80# text — Our go-to for booklet interiors and multi-page documents. Feels like a quality magazine page.
100# text — A step up. Heavier feel, still folds well. Good for premium booklet pages or single-sheet flyers where you want a little more heft.
80# cover — Light cardstock. Works for postcard mailers and lighter business cards.
100# cover — Our standard for business cards, rack cards, and postcards. Thick enough to feel serious.
14pt and 16pt C2S — These are measured in points (thousandths of an inch) instead of pounds, which is actually less confusing. 14pt is standard commercial cardstock. 16pt is premium.

Why it matters when you're ordering

If you're ordering from us, we'll confirm the stock before we print. But if you're ordering online or comparing quotes, here's what to watch for:

Always check whether the quote says "text" or "cover." A quote for "100# gloss" could mean either one.
If you want cardstock, ask for cover stock — or ask for a point weight (14pt, 16pt).
Request a sample. Any shop worth working with will send you one. We keep swatches on hand for exactly this reason.

The short version

Text stock is paper. Cover stock is cardstock. The pound number tells you weight relative to a basis size, not thickness. When in doubt, ask for the point weight — or better yet, ask to feel it before you commit.
