Designing posters, flyers and business cards

Churches, schools, shops and events all need posters, flyers and business cards, which makes them one of the easiest design services to start selling. Here's how to design ones that get results.

Start with the brief

Before opening Canva, ask the client:

  • Goal: what should people do? (Attend, call, visit, buy)
  • Audience: who is it for?
  • Key information: event name, date, time, venue, price, contacts
  • Where it will be used: printed A4/A3 posters, WhatsApp status, Facebook, a banner?
  • Brand: logo, colours, fonts
  • Deadline and quantity (for printing)

Standard sizes

A3 poster297 × 420 mmNotice boards
A5 flyer148 × 210 mmHandouts
Business card90 × 55 mm (common in Kenya) or 85 × 55 mm
WhatsApp/Instagram status1080 × 1920 pxVertical

Roll-up banner850 × 2000 mm

Layout principles

  1. Hierarchy: one dominant headline, then the key detail, then the rest.
  2. Alignment: line things up on an invisible grid; centred or left-aligned, consistently.
  3. White space: don't fill every corner. Space makes important things stand out.
  4. Proximity: group related info (date + time + venue together).
  5. Contrast: the call to action (phone number, "Register now") must pop.
  6. Repetition: reuse colours and fonts for a unified look.

The 3-second test

Hold the design at arm's length (or view it tiny on your phone). Can you tell what it is, when/where, and what to do in 3 seconds? If not, cut text and increase the size of the key parts.

Poster checklist

  • [ ] Headline readable from 3 metres away
  • [ ] Date, time, venue correct and double-checked (a wrong date is an expensive reprint)
  • [ ] Contact number/WhatsApp correct
  • [ ] Logo included, not stretched
  • [ ] High-quality photos (not blurry screenshots)
  • [ ] No spelling mistakes (read it backwards, or ask someone else)
  • [ ] Client approved the final proof in writing

Business cards

Front: logo, name, title. Back (or same side): phone, WhatsApp, email, website, location, maybe a QR code linking to your website or WhatsApp.

  • Keep text at least 8 pt.
  • Keep important content inside the safe zone, about 3–5 mm from the edges.
  • Use good card stock (e.g. 300 gsm) and consider matte lamination.

Preparing for print

SettingWhy
Bleed (usually 3 mm)Extend backgrounds past the edge so no white lines appear after cutting
Safe zoneKeep text away from edges
300 DPI imagesSharp printing (72 DPI web images look blurry)
CMYK coloursPrinters use CMYK; bright screen colours may print duller
PDF Print exportIn Canva: Download → PDF Print, tick "Crop marks and bleed"

Talk to your printer before designing: ask their preferred file type, bleed and paper options.

Designing for WhatsApp and social media

  • Vertical 1080 × 1920 for Status; big text (phones are small).
  • Put key info in the middle: the top and bottom may be covered by app buttons.
  • Fewer words than print: people swipe in 1–2 seconds.
  • Export as PNG (sharp text) or JPG (photos).

Pricing your design work

Consider: time, number of revision rounds included (e.g. 2), whether you supply print-ready files and editable source files, and rush fees. Always agree the price and revisions before starting, and take a deposit.

Who needs posters and flyers

Despite social media, printed and digital posters remain everywhere: church events, school open days, product launches, political and community meetings, restaurant menus, gym offers, concert promotions and WhatsApp Status adverts. Designing posters is often the first paid work for new graphic designers, and cyber cafés and print shops design them daily. A well-designed poster gets the message across in seconds; a cluttered one gets ignored.

The anatomy of an effective poster

ElementPurposeTip
HeadlineGrabs attention, states the main ideaShort, large, high contrast
VisualSupports the message, draws the eyeOne strong image beats many small ones
Key detailsWhat, when, where, priceEasy to scan; group related info
Call to actionWhat to do next"Call/WhatsApp 07XX...", "Register at...", "Visit us at..."
BrandingWho it's fromLogo and brand colours, not too large

Visual hierarchy: guiding the eye

Use these to show what matters most:

  1. Size: biggest = most important.
  2. Contrast: bright accent colour on key details.
  3. Position: top and centre are seen first; people often scan in a Z or F pattern.
  4. White space: space around an element makes it stand out.
  5. Alignment: a clean grid makes information easier to follow.

Squint test: blur your eyes (or zoom out). The headline, image and call to action should still be visible.

Grids and alignment

  • Divide the page into columns (e.g. 3 or 4) and margins.
  • Align text and images to the grid edges.
  • Keep consistent margins around the edges (at least 5–10 mm for print, inside the safe area).
  • Use alignment tools in Canva, Photoshop, Illustrator or Affinity rather than eyeballing.

Writing poster copy

WeakStrong
"We are pleased to inform you of our upcoming event""Free Coding Bootcamp for Youth"
"Many products available at good prices""Back-to-School Sale: up to 30% off"
"Contact us for more information""WhatsApp 0712 345 678 to book your seat"

Keep text short; every extra word reduces readability. Check spelling, dates, phone numbers and prices twice; ask someone else to proofread.

Designing for different formats

FormatSizeNotes
A4 / A3 poster210×297 mm / 297×420 mmMost common print sizes
A5 flyer148×210 mmHand-outs
Roll-up bannere.g. 850×2000 mmKey info at eye level; bottom often hidden behind stands
WhatsApp Status / Stories1080×1920 pxKeep text away from top/bottom edges (app UI covers them)
Instagram post1080×1080 or 1080×1350 pxBold, minimal text
Facebook event coverCheck current recommended sizeText in the centre safe area

Design a master version, then adapt it to each format, keeping consistent colours, fonts and imagery.

Print preparation in detail

  1. Document size + bleed: add 3 mm bleed on every side for designs that run to the edge.
  2. Safe zone: keep text and logos at least 3–5 mm inside the trim line.
  3. Resolution: images at 300 DPI at final print size.
  4. Colour mode: CMYK for print; convert and check colours.
  5. Fonts: outline fonts or embed them in the PDF.
  6. Export: high-quality print PDF (e.g. PDF/X) with crop marks and bleed if the printer asks.
  7. Proof: check a printed proof before the full run.

Talk to the printer before designing: ask for their preferred file format, bleed and paper options.

Working with clients on posters

  1. Brief: purpose, audience, key details, deadline, sizes, brand assets, budget.
  2. Gather content: final text, logos (vector if possible), photos.
  3. Concept: one or two directions.
  4. Revisions: agree on the number of revision rounds in advance (e.g. two).
  5. Approval: written approval of the final proof (spelling, dates, numbers).
  6. Delivery: print-ready PDF plus social media versions (PNG/JPG).

Common mistakes

MistakeFix
Too much textCut to headline, key details and call to action
Low-resolution images from WhatsAppAsk for originals; use quality stock photos
Text over busy photosAdd an overlay or a solid text box
No clear call to actionAdd a phone number, link or QR code
Forgetting bleedSet it up from the start
Wrong phone number or dateProofread and get written client approval

Practice

  1. Redesign a cluttered poster you've seen locally, keeping only essential information.
  2. Design an A4 event poster with bleed, then adapt it to WhatsApp Status and Instagram sizes.
  3. Write three headline options for a back-to-school sale and pick the strongest.
  4. Prepare a print-ready PDF with CMYK, 300 DPI images and 3 mm bleed.
  5. Do the squint test on your design and adjust the hierarchy.
Think about it: A church poster lists 14 activities, 6 speakers with photos, 3 phone numbers and a long Bible verse in small text. What would you change?Show answer

Focus on the main message: a clear headline (the event name), date, time, venue and one contact number. Show one or two key speakers, move the full programme to a separate handout or link/QR code, keep the verse short or use it as a subtle background line, and create space so the important details stand out.
