What You Get (and Why It Works)
- Exact Format: A6 postcard (105 × 146 mm)—a postal-friendly size that’s compact enough for efficient mailing but large enough for readable headlines and visuals.
- Material: Premium white cardboard with a smooth, sturdy texture that resists bending and keeps artwork flat and vibrant.
- Print Surface: Double-sided printing ready—use the full canvas to layer campaign images, brand voice, and scannable actions.
- Visual Quality: Clean whites and solid colour fields ensure your custom postcards look professional across lifestyle, retail, and B2B campaigns.
- Versatility: From product launches to appointment reminders, from promotional postcards to event invitations, from table drops to package inserts—the A6 format does it all.
Why A6? Because it fits the way people actually consume print: a single glance, a single takeaway, and a single call-to-action. The smaller footprint trims print and postage costs while increasing the likelihood your message is read, saved, or snapped for later.
Use Case Scenario (Lifestyle Storytelling That Converts)
Morning café launch: Your roastery is opening a second location. On every latte lid, staff slide a high-quality A6 postcard featuring a hero photo, a simple map, and a QR code to a “free espresso” welcome. The white cardboard postcard stands firm against light moisture on the counter and slips into bags without curling. By lunch, your analytics show a spike in QR scans and reservation requests.
Fitness studio referral: A PT studio runs a “bring a friend” month. Trainers hand out double-sided A6 postcards—front shows a bold offer, back lists class types and a short “how to start” guide. Clients pin them to fridges, snap them for Instagram stories, and hand them to friends after a Saturday session. Bookings climb steadily with minimal spend.
Bookshop event invite: An author signing needs a classy reminder. Staff tuck A6 105×146 mm postcards into shopping bags. The smooth white postcard preserves typography, so the reading time and location stay crystal clear. The back hosts a scannable pre-order link and a short blurb. Attendance exceeds capacity; the postcards become keepsakes.
Clinic recall reminders: A local dentist replaces generic SMS nudges with tangible appointment postcards that show after-care tips on the back. Families stick them on the fridge; recall rates improve, and missed appointments drop. The lifetime value of each patient rises.
D2C inserts that earn their keep: A skincare brand slips a double-sided promotional postcard into every shipment—front champions a new product; back features a loyalty code and regimen tips. Redemptions grow, and the insert more than pays for itself.
How It Helps the Businesses (Targeted Niches, Real Benefits)
- Retail & Hospitality: Turn every bag, table, and takeaway into a touchpoint. Promotional postcards drive footfall with clear offers and QR-enabled menus.
- Health & Wellness: Clinics, salons, and studios use A6 postcards for reminders, post-care guides, and referral programs—easy to keep, easy to act on.
- Education & Non-Profit: Open days, donor drives, timetable changes—high-quality postcards deliver clarity and credibility on a tight budget.
- Professional Services: Real estate, finance, legal—announce seminars, launches, and check-ins. The compact size reduces complexity while keeping the brand polished.

The common thread: A6 postcards are a low-friction medium with a high return on attention. They slip into daily life without feeling pushy and deliver a visible call-to-action at exactly the right moment.
How It Solves “Packing” Problems (Mailing & Handling Pain Points, Gone)
- Bending and corner scuffs: The sturdy white cardboard base keeps edges neat and artwork intact through sorting, stacking, and letterbox drops.
- Ink rub and readability: The smooth postcard surface supports crisp colour fields and fine type, reducing smudging and ensuring legibility.
- Crowded layouts: Double-sided printing frees space; place the bold message and hero image on the front, and commands, T&Cs, and contact details on the back.
- Labeling and addressing: The A6 (105×146 mm) format reserves adequate room for addresses, stamps, and QR codes without cramping design.
- Bulk handling: A6 stacks efficiently for bulk postcards in fulfilment lines. Bundles are easy to count, shrink, and distribute.
- Envelope compatibility: Need an envelope? A6 plays nicely with common C6 options for occasions where you want a more formal presentation.
How It Improves Operations and Sales Growth
- Lower cost per touch: Compared to oversized mailers, A6 postcards reduce print and postage costs while maintaining strong response rates.
- Higher response clarity: One format, one message, one action. That focus reduces decision fatigue and increases conversions—scan, book, buy, visit.
- Faster campaign cycles: The standardized A6 105×146 mm spec speeds design, proof, and production—meaning you can test more offers more often.
- Cross-channel lift: Pair postcards with short URLs and QR codes to amplify digital campaigns. Offline to online becomes a single step.
- Post-purchase value: Inserts drive repeat business, reviews, and loyalty enrolments—converting every shipment into a growth channel.
How It Elevates End-Consumer Perception
- Tactile credibility: A thick, smooth white postcard feels intentional and premium—more like a keepsake than an ad.
- Design clarity: Rich whites and crisp type set a professional tone; images pop, logos read cleanly, and colour blocks hold.
- Shareability: The compact proportion photographs beautifully; recipients snap, save, and share, extending your reach organically.
- Simplicity that respects time: A6 encourages brevity—consumers absorb the message in seconds and know exactly what to do next.
Material Quality (Why White Cardboard Matters)
- Smooth print surface: Premium white cardboard supports high-quality double-sided printing with consistent ink laydown and faithful colour.
- Rigidity that travels: The board resists dog-ears and creasing through mail sorting, door drops, and day-to-day handling.
- Edge integrity: Clean edges protect image borders and small typography; your design looks as sharp in the mailbox as it did on screen.
- Professional feel: The subtle heft of high-quality postcards signals brand seriousness, boosting trust from the first touch.
Easy to Use (“Installation” Made Simple)
- Design smart: Keep a bold headline and hero image on the front; place details and the call-to-action on the back.
- Address and stamp area: Leave a clear zone for address labels or handwriting; position QR codes away from postage marks.
- Print and bundle: A6 postcards stack efficiently for kitting, door drops, and in-store handouts.
- Deploy anywhere: Slip into bags, add to parcels, place on counters, include in event packs—no sleeves, no glue, no fuss.
Size and Layout Guidance
- Format: A6 postcard – 105 × 146 mm (portrait or landscape layouts both work beautifully).
- Grids that breathe: Use generous margins and a 2–3 column grid to keep headlines punchy and body text readable.
- Typography: Pair a strong display style for headlines with a highly legible text face at 9–11 pt for details.
- Image strategy: One focal image is enough; let the white of the smooth cardboard act as negative space to elevate the subject.
- Action design: QR codes should be at least 20–25 mm square with safe margins; include a short URL as a backup.
Printing & Customisation Options
- Double-sided printing (standard): Make full use of the postcard’s two surfaces—front for emotion, back for action.
- Colour control: Keep brand colours bold and simple for maximum on-the-move readability.
- Spot finishes (optional based on your spec): If your campaign requires extra pop, consider selective varnish or foil on future variants; the white cardboard base is a reliable canvas.
- Versioning and personalisation: Create micro-batches for neighbourhoods, segments, or language groups without re-inventing the format.
Practical Tips for Better Results
- One postcard, one job: Resist the urge to cram offers; clarity outperforms clutter.
- Front = feel, back = detail: This split guides eyes and keeps your hierarchy clean.
- Make value obvious: Time-bound offers and visible QR codes improve scan and redemption rates.
- Measure everything: Track QR scans, short URLs, and coupon codes to learn what headlines, images, and offers perform best.
- Think lifecycle: Use the A6 postcard at multiple points—new customer welcome, reorder nudge, lapsed win-back, event follow-up.
