Most leaflets meet their end in a hallway, jammed under a takeaway menu and swept into the bin by Friday. That is rarely a failure of effort — it is a failure of design. The leaflets people pin to a noticeboard, tuck into a wallet or photograph for later are seldom the glossiest ones. They are the ones that gave the reader a reason to keep them. Here is how to build that reason into your next print run.

Start with the question: why would anyone keep this?

Before you open a design file, write down three reasons a customer might hold on to what you are printing. In practice, those reasons fall into a few familiar categories.

• They need the information again later — opening hours, prices, an address, a postcode.
• They intend to act on it — a quote, a booking, a seasonal offer with a genuine expiry date.
• It is useful in its own right — a checklist, a calendar, a simple local map, a size guide.

If you cannot name at least two, you are designing something to be thrown away. Add something worth keeping before you think about colour.

Choose a format that survives a kitchen drawer

Physical practicality is underrated. Size and paper weight do a great deal of the persuading, long before anyone reads a word.

• A5 (148 x 210mm) is the workhorse: big enough for a clear message, small enough for a pocket or a pinboard.
• DL (99 x 210mm) suits price lists and menus, and fits a standard envelope if you are posting them.
• Card stock at 250–300gsm feels like a decision rather than a giveaway. Flimsy 130gsm paper signals "junk mail" before it is unfolded.
• Uncoated paper takes pen marks, so people can circle, tick or jot a note. That quietly encourages keeping.

If your leaflet folds, check that the fold sits on a natural grid line and does not slice through a headline or a face.

Layout that can be read in four seconds

Most people give a leaflet about four seconds before deciding. Design for the scan, not the study.

• Give one dominant element — usually your name and what you actually do — the top third of the page.
• Keep a clear hierarchy: headline, subheading, body. Two typefaces is plenty; three is a crowd.
• Use generous margins of at least 10mm. White space is not wasted space; it is what makes the message look confident.
• Set body text left-aligned rather than justified, and avoid long lines. Aim for 45–70 characters per line.
• Keep body copy no smaller than 9–10pt in print, and larger if your audience skews older.

Colour that signals quality, not chaos

Restraint reads as confidence. Two or three colours, with one strong accent used sparingly, will always outperform a rainbow.

• Build a palette from your logo, then add one neutral: off-white, warm grey or a deep navy.
• Keep contrast high — dark text on a light background. Pale grey on white looks elegant on screen and vanishes on paper.
• Reserve the accent colour for the call to action, so the eye lands there first.
• Remember that print is not screen. Vivid RGB blues and greens often shift duller in CMYK, so ask to see a proof before committing to a full run.

Content that earns a place on the fridge

Content is what turns a good-looking leaflet into a kept one. Practical beats promotional every time.

• Answer the obvious questions: where, when, how much, how to book, how long it takes.
• Make one specific offer with a real deadline. "10% off" without a date is forgettable; "10% off until 31 March" gives someone a reason to hold on.
• Include something reference-worthy: a seasonal checklist, a short diagram, opening hours in a clearly boxed panel.
• Write to one person. Use "you", keep sentences short, and cut the jargon your trade has grown used to.
• Give a readable contact block — phone, email, website, postcode — in at least 10pt type, not squeezed into the bottom corner.

Finishing touches that make people pause

Small production decisions create the "this feels decent" moment that buys you a second look.

• Match paper weight to purpose: 170–250gsm for a leaflet, 300gsm or more for a card people will keep in a wallet.
• Matte lamination feels premium and resists fingerprints. Soft-touch finishes are memorable but can mark easily with greasy fingers.
• A single spot colour or foil accent on a logo adds weight for very little cost, provided you use it once.
• Print to full bleed with 3mm of extra image beyond the trim, and keep all text at least 5mm inside it.
• Proofread aloud, then ask someone unfamiliar with your business to read it. One typo undoes a beautiful layout.

Finally, test small before you commit. Print 250, hand them out in the places your customers actually go, and watch what happens to them. Ask a few people whether they kept it and why. Then amend the design before the larger run. A leaflet that gets kept once is worth ten that go straight into the recycling.
