Two flyers leave the same printer on the same afternoon, carrying identical artwork. One ends up pinned to a fridge door. The other goes in the bin before the reader reaches the second paragraph. Paper is rarely the only reason, but it is more often the reason than most people expect.

Weight and finish are the two decisions sitting behind that difference, and they are also the two that get rushed in the last hour before a job goes to press. Here is what the numbers mean, what each finish actually does, and how to choose without paying for qualities nobody will notice.

What a Paper Weight Actually Measures

Paper weight is given in gsm — grams per square metre. A 150gsm sheet is one whose square metre weighs 150 grams. The figure is independent of size, which surprises people: an A6 postcard and an A2 poster can both be printed on 300gsm stock, and neither is technically "lighter" than the other.

That is also why weight is not the same thing as thickness. Caliper, measured in microns, tells you how thick the sheet is, and two papers of equal weight can differ noticeably here. Coated stocks are pressed and calendered, so they are dense and comparatively thin. Uncoated, bulky stocks feel fatter than their weight suggests. A 250gsm uncoated board can feel more substantial in the hand than a 300gsm gloss.

If you have worked with American specs, you will have seen pounds instead — lb text, lb cover. Those are basis weights tied to particular sheet sizes, so 80 lb text and 80 lb cover are nowhere near the same paper. Ask for gsm and the conversation gets much shorter.

The practical upshot: don't choose from a table. Ask for a swatch or a dummy. Most printers will happily post a sample pack, and ten seconds of holding the real thing beats any specification.

The Weights You Will Actually Be Choosing Between

Nearly all flyer work lands in one of five bands.

• 80–100gsm: thin, office-like, and cheap. Ink shows through from the reverse side, so double-sided designs need light coverage. Fine for a stack of handouts at a fair or a door drop where most copies will be discarded anyway.
• 120–170gsm: the workhorse range. 135–150gsm holds a fold, feels like a proper leaflet, and costs very little more than the thin stuff. Most restaurant and event leaflets sit here.
• 200–250gsm: the sheet starts to feel like an object rather than a page. Good for price lists, menus, and anything handed to someone directly.
• 300–350gsm: premium territory. Stiff, satisfying, and the point at which creasing becomes mandatory rather than optional.
• 400gsm and above: business-card and invitation stock. Heavy, expensive, and awkward to fold at all.

Folding deserves its own warning. Anything much above 170gsm needs a score line — a pressed crease — before it is folded, or the paper will crack along the fold and the coating will show white. Coated stock is the worst offender. If your design folds, either drop to 150gsm or budget for scoring and accept a slightly rounded fold.

Coated, Uncoated and the Finishes In Between

Gloss and silk

Gloss is the shiny one. Silk, sometimes sold as matte or satin, is coated too but with a lower sheen. Both seal the surface, which keeps ink sitting on top of the sheet instead of sinking in: photographs stay crisp, gradients stay smooth, and fine type stays legible. Silk is easier to read under harsh lighting and shows fewer fingerprints.

Uncoated

Uncoated is absorbent. Ink sinks into the fibres, so colours look softer and often slightly darker than they did on screen, and large solid areas can look faintly mottled rather than flat. In exchange you get a natural feel, a surface that takes pen and pencil beautifully, and a look that suits anything pretending to be a letter, a note or a menu. Text-heavy pieces are usually more comfortable on uncoated.

Textured, recycled and coloured stocks

Laid, linen and embossed papers give a flyer a tactile identity nothing else can match. Two cautions. Textures break up fine type and thin reverse-out text, so keep type sizes generous. And recycled or coloured stocks vary between batches and shift photographic colour more than white coated paper does. They also cost more and often carry larger minimum orders, and not every digital press can run them. Check before you design around one.

How Finish Changes Colour, Feel and Durability

Colour is the first thing people notice and the hardest to predict. A rich black on gloss looks deep and even; the same black on uncoated can look washed out and slightly grey. Photographs sing on coated stock and go quiet on uncoated. If colour accuracy matters, ask for a proof on the actual stock rather than on whatever the printer uses for proofs.

Then there is handling. Coated sheets resist smudges, moisture and greasy fingers, which is why menus live on them. Lamination adds scuff and water resistance and gives you a surface a marker will write on; soft-touch lamination feels velvety but collects fingerprints, so think twice before using it on a menu that gets handled all evening. Spot UV — gloss varnish applied to selected areas — only works over a coated base and is rarely economical in small runs. And a small thing worth knowing: a stack of gloss flyers slides off a table. If they will sit out on a counter, a silk finish stays put.

What This Adds to the Bill

Moving from 135gsm to 300gsm costs more, but the cost curve is gentler than most people fear. The real budget surprises usually come from finishing: scoring, folding, lamination and special stocks all carry setup charges that don't shrink with the print run. On short runs, choose from the stocks your printer already holds. A special order of 250gsm textured paper for 500 flyers can double the unit price on its own.

It is also perfectly reasonable to split the job. Print a small batch on heavy stock for the people you hand a flyer to directly, and a larger batch on 135gsm for the door drop. And if the flyers are going in the post, check the weight and thickness limits before you fall in love with 400gsm — bulky stock can push a mailing into a higher postal band.

A Five-Minute Way to Choose

1. Decide what happens to the flyer. Read once and binned: 135gsm. Kept for weeks: 250–300gsm. Handled with wet hands: coated, ideally laminated.
2. Decide whether it folds, and check that the weight you want survives a fold without scoring you can't afford.
3. Decide whether anyone will write on it. If yes, uncoated.
4. Match the finish to the content. Photo-led: coated, gloss or silk. Text-led: uncoated or silk.
5. Ask for a dummy on the real stock, print one copy, fold it, write on it, and leave it in a bag for a day.
6. Confirm the printer stocks it before you commit to the design.

The right combination is usually the cheapest one that survives the journey to the reader's hand — not the heaviest one on the shelf.
