A3 is 297 × 420 mm, twice the size of A4. At this size a flyer stops being something you slip into a pocket and becomes something you display: a shop-window special, a notice on a community or campus board, a programme taped up at a venue entrance or a fixture list in a clubhouse. It is also handy for folded handouts such as event maps and timetables.
Design A3 flyers to be read from a step or two away. Use a large headline, a strong image and keep small print to the essentials. For pieces that will be handled or displayed for a while, choose a heavier stock or add lamination to help resist creasing, moisture and fingermarks.
FAQs
Is an A3 flyer the same as an A3 poster?
The size is the same. A3 flyers are usually ordered in larger quantities and may be double-sided or folded, while posters tend to be single-sided display prints, sometimes on photo paper.
Will an A3 flyer fit through a letterbox?
Not flat. If you plan to distribute A3 by hand or post, choose the half-fold option so it folds down to A4.
Can I get A3 flyers on the same day?
Same-day production may be possible for small quantities, subject to product eligibility, stock, capacity, quantity, artwork readiness and finishing, with full payment, usable artwork and approvals before the configured cutoff. Production completion and delivery arrival are separate commitments.
