The most popular flyer sizes in the UK are A5 (148 × 210 mm) for general handouts, A6 (105 × 148 mm) for counters and door drops, DL (99 × 210 mm) for menus and anything going in an envelope, and A4 (210 × 297 mm) when there is a lot to say. The right one depends less on the words and more on where the flyer will end up: a hand, a letterbox, a counter, an envelope or a wall. This guide matches the size to the job, with the artwork sizes for each.

Choose by where it is going #
- Through letterboxes: A5 or A6. Both fit any letterbox flat. Keep the key message on the top half, which is the part that shows as it lands.
- Handed out in the street: A6 or A5. People take a small flyer more readily and are more likely to keep it.
- On a counter or reception desk: A6 or DL, which fit standard leaflet holders.
- In an envelope: DL fits a DL envelope flat, A5 fits a C5, A4 fits a C4, and A6 fits a C6. An A4 sheet folded in three also fits a DL envelope.
- On a noticeboard or in a window: A4 or A3, read from a step or two away.
- Takeaway menus: DL for a short menu, A5 or A4 for a full one. If it needs more panels, a folded leaflet does the job; see flyer vs leaflet.
Paper weight by size #
Small flyers feel flimsy on thin paper, because they are held by the edges. For A6 and smaller, pick the heaviest paper on offer so it feels more like a card. For A5 and A4 handouts, a lighter paper is fine and keeps postage down if you are mailing them. Our guide to which gsm paper to choose goes into more detail.
Setting up the artwork #
- Add 3 mm of bleed on every side, which is the artwork size column above; see bleed and safe area.
- Keep text at least 3 to 5 mm inside the finished edge.
- Use photos at 300 dpi at the printed size; DPI for printing explains how to check.
- Remember the A sizes scale: a layout made for A5 enlarges cleanly to A4 or A3. The full list is in A paper sizes in mm.
Or use the free online designer on the product page, which has the bleed and safe area set for each size.
