Quick answer

For most home and small-office printing, you want 20–24 lb bond, 92+ brightness, white, letter-size (8.5" x 11") multipurpose paper. Step up to 28–32 lb for resumes, presentations, and double-sided documents that need to feel substantial. Use dedicated photo paper for photos — never plain copy paper. The four properties that actually matter are weight, brightness, finish, and size, and this guide explains each one in plain English.

The four properties that matter

Walk down the paper aisle and you'll see numbers like "24 lb," "96 bright," "98 GE," "letter," "matte," "premium." Strip away the marketing and there are really just four specs that change how a sheet of paper performs in your printer:

• 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 four right and almost any printer will produce sharp, professional 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 weight: lb and GSM, decoded

In the U.S., paper weight is listed in pounds (lb) — the weight of 500 sheets of the paper at its uncut "basis size." Outside the U.S., it's listed in GSM (grams per square meter), which is more intuitive: higher number = heavier sheet.

Here's a cheat sheet:

• 20 lb (~75 GSM) — Standard copy paper. Cheap, thin, fine for everyday black-and-white documents.
• 24 lb (~90 GSM) — Multipurpose paper. The sweet spot for home and office: better opacity, less show-through on duplex prints, still inexpensive.
• 28–32 lb (~105–120 GSM) — Premium / presentation paper. Feels noticeably heavier. Great for resumes, proposals, and color presentations.
• 65–80 lb cover / cardstock (~175–215 GSM) — Stiff. Used for invitations, business cards, postcards, and craft projects.
• Photo paper (varies, often 240–300 GSM) — Coated specifically to absorb inkjet ink without bleeding. Required for real photo prints.

If you're not sure where to start, 24 lb is the safest single-paper choice for a home office.

2. Brightness: what those "92," "96," and "98" numbers mean

Brightness measures how much blue light (specifically, light at 457 nanometers) the paper reflects, on a 0–100 scale. A higher brightness number means whiter-looking paper, which means higher contrast for your text and more vivid colors for your images.

• 92 brightness — Standard copy paper. Perfectly adequate for everyday printing.
• 96 brightness — Noticeably whiter. A good upgrade for documents you hand to clients.
• 98–100 brightness — Premium. Use it when color accuracy matters or when the document is the deliverable.

One thing to know: U.S. brightness ratings (TAPPI) and the European "whiteness" rating (CIE) are not the same scale. A paper labeled "100 brightness" in the U.S. and "165 whiteness" in Europe can be the same sheet. Don't try to compare across the two.

3. Finish: matte, glossy, satin, and everything between

Finish is the surface texture and coating of the paper. It controls how ink sits on the page and how the final print looks and feels.

• Uncoated / matte — Standard for documents. No glare, easy to write on, no smudging. Best for text and everyday color.
• Glossy — Shiny, high-contrast, vivid color. Best for photos and marketing pieces. Fingerprints show easily.
• Satin / luster / semi-gloss — In between. Reduces glare while keeping color punch. A favorite for photo prints you plan to frame.
• Linen / laid / textured — Specialty finishes for stationery, certificates, and invitations.

Important rule: only use coated photo paper in inkjet printers unless the package specifically says "laser." Laser-printer fusers run hot enough to melt or warp inkjet photo coatings.

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

The size you need depends on what you're printing and where you live.

• Letter (8.5" x 11") — The U.S. and Canadian default. 99% of home printing.
• Legal (8.5" x 14") — Longer sheet for contracts and legal documents.
• Tabloid / Ledger (11" x 17") — Used for spreadsheets, posters, and print proofs. Requires a wide-format printer.
• A4 (8.27" x 11.69") — The international standard. Slightly narrower and taller than letter.
• 4" x 6" / 5" x 7" / 8" x 10" — Common photo sizes. Most photo printers have dedicated trays for these.

Inkjet vs. laser: does it actually matter?

For everyday paper, not really — most modern multipurpose paper is rated for both inkjet and laser printers. Where it matters:

• Photo paper is engineered for one or the other. Don't mix.
• Heavy cardstock — check your printer's max paper weight spec before buying. Inkjets handle thicker stock better than most lasers.
• Specialty papers (transfer paper, label sheets, sticker paper) — always buy the version made for your printer type.

One last thing: storage matters

Paper is hygroscopic — it absorbs moisture from the air. Damp paper curls, jams, and prints poorly. Keep your reams sealed in their wrapper until you're ready to use them, store them flat in a cool, dry place, and don't leave a half-empty tray sitting in a humid room for weeks. This single habit will eliminate most "mystery" jams and streaks.
