Designing for scan-and-go
Most flyers are looked at for under three seconds before the reader decides whether to keep or discard them. Lead with one headline and one image; everything else is supporting detail. The headline should be readable from 1 metre away — that means at least 28 pt for a single line, or 36 pt+ for a multi-line title.
Frequently asked questions
Why is A4 a popular flyer size?
A4 fits in standard racks, magazines, folders and noticeboards. It is large enough to carry a substantial message but small enough to print cheaply on any modern press. Print shops can run thousands of A4 flyers in a single pass.
How much bleed should an A4 flyer have?
The standard is 3 mm of bleed on every side, giving an export size of 216 × 303 mm. The trim line stays at 210 × 297 mm.
Where should I keep important content?
Inside a safe area 5 mm in from the trim line — 200 × 287 mm of usable space. The corners and edges of an A4 flyer often get nicked or curled in transit; pulling content inward gives the design tolerance.
What paper weight makes a good flyer?
130–170 gsm gloss or silk for mass-distribution flyers. 250–300 gsm for premium handouts that need to feel substantial. Anything below 100 gsm reads as office paper rather than a printed flyer.
Single-sided or double-sided?
Double-sided printing only adds about 30% to the cost in most printers and effectively doubles your design area. Unless the back is intentionally blank for note-taking, double-sided is usually the better value.
