Quick answer

For most home and small-office printing, buy 20–24 lb, 92–96 brightness, white, letter-size multipurpose paper. Step up to 28–32 lb and 96–98+ brightness for resumes, presentations and two-sided documents. Use dedicated photo paper for photos. The four specs that matter are weight, brightness, finish and size — and the difference between 92 and 96 brightness is small but visible: 96 looks whiter and makes color and text pop a little more.

The four properties that matter

• Weight — how heavy and stiff the sheet feels.
• Brightness — how much light the paper reflects.
• Finish — the texture and coating of the surface.
• Size — the dimensions of the sheet.

Get those right and almost any printer will produce sharp output. Get them wrong and you'll fight jams, ink bleed and washed-out prints no matter how good your printer or ink cartridges are.

1. Paper brightness: what 92, 96 and 98 mean

Brightness measures how much blue light (at 457 nanometers) the paper reflects, on a 0–100 scale (the U.S. TAPPI/ISO brightness scale). Higher brightness looks whiter, which raises contrast for text and makes colors more vivid.

• 92 brightness — standard copy paper. Perfectly fine for everyday printing.
• 96 brightness — noticeably whiter. A good upgrade for documents you hand to clients.
• 97–100 brightness — premium. Use it when color accuracy matters or the document is the deliverable.

92 vs 96 bright paper: is the difference worth it?

Side by side, 96 looks crisper and slightly bluer-white; on its own, most people can't tell for plain text. Choose 92 for internal documents and drafts, 96 for anything client-facing or printed in color. The price gap is usually small, so 96 is a sensible default if you only stock one paper.

92 vs 98 or 100 brightness

The jump from 92 to 98+ is more obvious, especially with color graphics and on laser printers. Pair 98+ brightness with 28–32 lb weight for presentations and color marketing pieces.

U.S. brightness and the European CIE "whiteness" rating are different scales — a sheet labeled "98 bright" in the U.S. may show "160+ CIE" elsewhere. Don't compare across the two.

2. Paper weight: lb and GSM, decoded

U.S. paper weight is listed in pounds — the weight of 500 sheets at the paper's uncut basis size. Elsewhere it's GSM (grams per square meter). Higher number = heavier sheet.

• 20 lb (~75 GSM) — standard copy paper. Thin, cheap, fine for everyday black-and-white.
• 24 lb (~90 GSM) — multipurpose paper. Better opacity and feel; the home-office sweet spot.
• 28–32 lb (~105–120 GSM) — premium/presentation paper for resumes, proposals and color.
• 65–110 lb cover (~175–300 GSM) — cardstock for invitations, cards and crafts.
• Photo paper (often 240–300 GSM) — coated to hold inkjet ink without bleeding.

Printer paper thickness

Thickness ("caliper") is measured in thousandths of an inch (mils or points). As a rough guide, 20 lb copy paper is about 4 mil, 24 lb about 4.5–5 mil, 32 lb about 5.5–6 mil, and 80–110 lb cardstock about 9–14 mil. Thickness depends on the paper's density as well as its weight, so two papers of the same weight can feel slightly different.

What's the maximum paper weight for an inkjet printer?

Most home inkjets accept about 20–24 lb in the main tray as a default and up to roughly 60–80 lb cover (about 160–220 gsm) through the rear or manual feed; some photo-oriented models handle 300 gsm. Check your printer's specification sheet for the exact limit (often listed in gsm) before buying cardstock.

Opaque paper vs. regular printer paper

"Opaque" paper (often sold as opaque offset or premium opaque) is made to block show-through, so it's better for two-sided printing, booklets and heavy color. Regular 20 lb copy paper is thinner and lets more of the back side show through. If you print duplex or color often, an opaque 24–28 lb sheet is a meaningful upgrade.

3. Finish: matte, glossy, satin and more

• Uncoated / matte — standard for documents. No glare, easy to write on.
• Glossy — shiny, vivid color for photos and marketing. Shows fingerprints.
• Satin / luster / semi-gloss — reduces glare while keeping color punch.
• Linen / laid / textured — for stationery, certificates and invitations.

Only use inkjet photo paper in inkjet printers unless the package says "laser" — laser fusers can melt inkjet coatings. Printing photos? See glossy vs. matte vs. luster photo paper.

4. Size: letter, legal, A4 and the rest

• Letter (8.5" x 11") — the U.S. and Canadian default.
• Legal (8.5" x 14") — contracts and legal documents.
• Tabloid / Ledger (11" x 17") — spreadsheets, posters and proofs; needs a wide-format printer.
• A4 (8.27" x 11.69") — the international standard.
• 4x6, 5x7, 8x10 — common photo sizes.

Inkjet vs. laser paper: does it matter?

For everyday multipurpose paper, no — most is rated for both. It matters for photo paper (made for one or the other), heavy cardstock (check your printer's maximum), and specialty media like transfer, label, sticker and magnetic paper. For color lasers, 28–32 lb at 98+ brightness gives the crispest results.

Choosing black or colored paper

Colored and black papers come in the same weights as white. For black paper, choose at least 65 lb cover if you want it to feel like cardstock, and remember that standard inks won't show on black — use white ink, metallic pens or opaque laser toner designed for dark media.

How to pick the right paper in 30 seconds

1. Everyday printouts → 20–24 lb, 92–96 brightness, matte, letter-size.
2. Resumes and presentations → 28–32 lb, 96–98+ brightness.
3. Color marketing → 32 lb premium or coated brochure paper, 98+ brightness.
4. Photos → inkjet photo paper, glossy or luster.
5. Invitations/cards → 65–110 lb cardstock — see the best cardstock for invitations.

Frequently Asked Questions

Does higher brightness paper use more ink?

No. Brightness affects how prints look, not how much ink the printer uses.

Is 96 bright paper good for printing photos?

It's fine for proofs and casual color, but real photos need coated photo paper.

What does "multipurpose" paper mean?

It's paper rated for inkjet, laser and copiers — usually 20–24 lb at 92–96 brightness.

Storage matters

Paper absorbs moisture from the air, and damp paper curls, jams and prints poorly. Keep reams sealed until use, store them flat somewhere cool and dry, and don't leave a half-empty tray in a humid room for weeks.
