Before printing advertising leaflets, answer a simple question: what does the recipient need to know? If the message contains only an offer and a phone number, a flyer may be enough. To present several services, a bi-fold or tri-fold may work better.
The type of leaflet determines the reading order, amount of copy, folding and the artwork supplied to the printer.
Quick choice: a flyer is an unfolded sheet; a bi-fold has two panels; a tri-fold has three. The best option is not the one with the most surfaces, but the one that organises the information most clearly.
Main types of advertising leaflet
Flyer or handbill
Used for a direct message, promotion or announcement. It can be printed on one or both sides.
Bi-fold leaflet
It has two panels and four surfaces when printed on both sides. It separates the front cover, information and contact details clearly.
Tri-fold leaflet
It has three panels and up to six printed surfaces. Check the fold and reading order before printing.
Four-panel leaflet
It contains four panels and supports several fold styles. It is useful when the content needs a longer sequence.
How to choose the format and dimensions
A4, A5 and A6 are common, but state whether the dimensions refer to the open or closed leaflet. Orientation affects the design, paper and distribution. Work with actual dimensions rather than the format name alone.
Campaign examples
| Objective | Format to consider | Reason |
|---|---|---|
| Announce an offer | Flyer | Short, direct message |
| Present a business | Bi-fold | Clear separation of sections |
| Explain several services | Tri-fold | More organised space |
| Describe a route | Four-panel leaflet | Sequence of panels |
Paper and finishes
Coated papers are often chosen when images are prominent; uncoated stocks provide a different appearance and suit certain pieces. Select grammage together with the fold, intended use and quantity.
How to design a readable leaflet
- Define a headline and main message.
- Order information by priority.
- Use images with sufficient effective resolution.
- Reserve space for contact details and the next action.
- Check typography, contrast and margins.
- Verify the panel order using a folded mock-up.
PDF preparation and quotation
Check bleed, trim size, fonts and colour settings against the production requirements. Price depends on the format, quantity, paper, printed sides, fold and finish, not simply on the number of copies.
