UK flyer and leaflet sizes
Flyer and leaflet formats follow ISO A-sizes plus DL. Pick the size for the job — letterbox drops, handouts, or insert campaigns — then match stock weight to how the piece will be handled.
Common flat sizes
A6 and A5 dominate handouts and counter piles. A4 suits posters-on-a-budget and detailed offers. DL (99 × 210 mm trimmed) is popular for letterbox and rack displays.
- A6 — compact handouts and appointment cards
- A5 — everyday flyers and menus
- A4 — detailed offers and one-pagers
- DL — racks, wallets, and many letterbox campaigns
Folded leaflets
Bi-fold and tri-fold leaflets turn a flat sheet into a compact brochure. Plan panels so headlines are not lost in folds, and keep maps or price tables away from the crease.
Stock and finish tips
130–170 gsm silk is a common flyer starting point. Heavier stocks feel more premium; uncoated stocks suit forms and handwriting. Add laminate when pieces will be handled repeatedly.
