A-series paper sizes guide

South Africa uses the international A-series of paper sizes. Each size is exactly half of the one before it, which makes scaling and folding simple. Here are the sizes, their artwork dimensions and what each is used for.

The sizes

  • A0: 841 x 1189mm – large posters, plans, displays.
  • A1: 594 x 841mm – posters, plans, seating charts.
  • A2: 420 x 594mm – shop posters, year planners.
  • A3: 297 x 420mm – posters, menus, folded brochures. Colour R9.00 per copy.
  • A4: 210 x 297mm – letters, flyers, documents. Colour R4.00, black and white R1.50.
  • A5: 148 x 210mm – flyers, booklets, notepads. Colour R1.90.
  • A6: 105 x 148mm – postcards, small flyers, invitations.

How the series works

A0 has an area of one square metre. Fold any A-size in half across its long side and you get the next size: A4 folded is A5, A3 folded is A4. All sizes share the same proportions, so a design made for A4 scales neatly to A3 or A5 without cropping. That is why an A4 flyer can easily become an A3 poster.

Adding bleed

Add 3mm on every side for print that runs to the edge. So an A4 file with bleed is 216 x 303mm, A5 is 154 x 216mm and A6 is 111 x 154mm. See bleed, trim and safe zone explained.

Every product page lets you pick a lead time. Economy takes about five working days and costs 10% less. Standard takes about three working days and is the price you see listed. Express is ready the next working day for 20% more, and Same-day costs 30% more for eligible items that are ordered, paid and print-ready by 09:00 on a weekday.

Same-day is priced high on purpose. If you can give us a few days, Economy or Standard saves you money.
