Leaflet vs Flyer: What Is the Difference?

People use the terms interchangeably

If you search for "leaflet printing" and "flyer printing," you will often land on the same products. Many print companies (including us) list them under one category. In everyday conversation, most people treat "leaflet" and "flyer" as the same thing. But there are differences, and knowing them helps you order the right product.

What is a flyer?

A flyer is a single, unfolded sheet of paper or card, printed on one or both sides. It is designed to be picked up, handed out, or posted through a letterbox. Flyers are typically A5, A6, or DL in size, and they carry a short, punchy message with a clear call to action.

Flyers are built for speed. You glance at one, get the message, and either act on it or move on. They are the print equivalent of a social media ad: brief, visual, and designed to prompt a single response.

What is a leaflet?

A leaflet is usually a folded piece of paper that contains more detailed information. The most common format is an A4 sheet folded into thirds (a tri-fold leaflet), which creates six panels of content. You will also see half-fold (A4 folded to A5) and gate-fold designs.

Leaflets carry more information than flyers. They are suited to explaining a service, presenting a range of products, or giving someone enough detail to make a decision. Think of the leaflet you pick up at a doctor's surgery, a tourist attraction, or an estate agent's office.

The physical differences

The main physical difference is the fold. A flyer is flat; a leaflet is folded. This changes how the reader interacts with it. A flyer delivers everything at once. A leaflet has a front panel that draws you in, then reveals more information as you open it.

Paper weight differs too. Flyers are often printed on heavier stock (300gsm to 400gsm) because they need to feel sturdy as a single sheet. Leaflets are usually on lighter stock (130gsm to 170gsm) because folding thick card cleanly is difficult and creates a bulky result. A 400gsm tri-fold leaflet would be awkward to open and hard to fold neatly in production.

When to use a flyer

Flyers are the right choice when your message is simple and your goal is a single action. Opening night at a new restaurant. A weekend sale. A local event. A discount code. A new business announcing itself to the neighbourhood. Anything where one headline, one image, and one call to action are enough.

They are also cheaper to produce per unit, faster to print, and easier to distribute. If you need something quickly for a specific promotion, flyers are the practical choice.

When to use a leaflet

Leaflets work better when you need to tell a longer story. A gym listing its membership options and class timetable. A tradesperson explaining their services with before-and-after photos. A charity outlining its mission and how to get involved. A property developer marketing a new site.

The folded format also works well in display racks and brochure holders. A tri-fold leaflet stands upright in a DL-sized holder, which is why you see them in reception areas, waiting rooms, and tourist information points across Belfast and beyond.

Does the distinction actually matter?

In practical terms, what matters is whether you need a flat sheet or a folded one, and how much content you need to fit. The word you use to describe it is less important than getting the format right for the job.

If you ask a printer for "500 flyers" and you actually want a folded A4 leaflet, they will ask you to clarify. If you ask for "500 leaflets" and you want a flat A5 card, same thing. The terminology is loose enough that most printers will check rather than assume.

Paper stock for each

For flyers, 350gsm silk is the most popular option. It is thick, durable, and holds colour well. Lamination (matt or gloss) adds protection and a better feel. For leaflets, 130gsm or 170gsm silk is standard. It folds cleanly, sits flat when opened, and keeps the cost reasonable on larger print runs.

Ordering the right product

When you are ready to order, think about three things: how much content you have, how the piece will be distributed, and what format suits the reader's experience. If in doubt, start with a flat flyer. If you find yourself running out of space, a leaflet is probably what you need.
