How it works

A3 vs A4 printers: which do you need?

A4 (210 × 297 mm) is the standard sheet for letters, invoices and most documents. A3 (297 × 420 mm) is exactly twice the size. You need an A3 printer or photocopier only if you print or copy drawings, spreadsheets, ledgers, posters, notices or booklets; an A3 machine also prints A4, but costs more and takes more space.

Who needs A3?

  • Architects, engineers and contractors printing or copying drawings.
  • Accountants and offices working with wide spreadsheets and ledgers.
  • Schools and colleges printing notices, charts and booklets.
  • Print shops and businesses making posters, menus or brochures.
  • Any office that copies books or bound files, which often need A3 to copy two facing pages at once.

A3 options: ink tank printer or photocopier

For occasional A3 printing, an A3+ ink tank printer such as the Epson EcoTank L8180 (photos), L15180 (colour business) or M15180 (mono business) is the low-cost route. For daily A3 copying, scanning and printing for a group, an A3 photocopier is built for the volume. Compare both in A3 printers and A3 photocopiers.

Can an A3 printer print A4?

Yes. A3 printers and photocopiers print A4 and usually A5 and Legal as well.

Is A3 printing more expensive than A4?

An A3 page uses about twice the toner or ink and paper of an A4 page, so it costs roughly twice as much per page. The machine also costs more to buy.
