Folded Leaflet Design Guide: Bi-fold, Tri-fold and More
Folded leaflets are one of the most versatile and widely used print formats in marketing — capable of carrying significantly more information than a flat flyer while remaining compact, easy to distribute and cost-effective to produce. But they require more careful design planning than flat print products. The fold type, panel sequence, content organisation and artwork setup all need to work together for the finished piece to look and function as intended.
In this guide, we walk through everything you need to design folded leaflets that communicate clearly, look professionally produced and print perfectly every time.
Choose the Right Fold Type
The fold type determines the number of panels, the reading sequence and the physical experience of the leaflet. Choose based on how much content you have and how you want the reader to engage with it:
Bi-fold (4pp)
A single sheet folded once to create four panels — front cover, inside left, inside right and back cover. The simplest and most flexible folded format. Works well for menus, price lists, event programmes and simple product or service overviews. The inner spread gives a generous canvas for content that benefits from a wide, open layout.
Tri-fold (6pp)
Two folds creating six panels. The right-hand outer panel folds in first, so it acts as the cover when the leaflet is closed. The most widely used leaflet format — popular for service guides, menus, brochures and promotional leaflets. Note that the folding panel is slightly narrower than the other two panels — always use our templates to ensure panel widths are correct.
Z-fold / Accordion fold (6pp)
Two folds in alternating directions creating six equal-width panels that expand like a concertina. Unlike the tri-fold, all panels are the same width. Works well for maps, timelines and content with a clear sequential flow — each panel naturally leads to the next.
Gate fold (6pp or 8pp)
Two outer panels fold inward to meet in the centre, opening to reveal a large inner spread. Creates a dramatic reveal effect that makes an immediate impression. Popular for product launches, premium invitations, luxury brochures and any piece where the physical experience of opening the leaflet is part of the communication.

Plan Content Panel by Panel
The most important design principle for folded leaflets is to treat each panel as a distinct unit of communication — not to design the flat sheet and then fold it. Each panel has a role:
- Front cover — your headline, key visual and brand identity. This is the first thing the reader sees and must give them a reason to open the leaflet. It needs to be strong enough to work as a standalone piece of communication
- Inside panels — the main content area. Organise information logically. Use section headings to create structure. Left-to-right reading sequence applies — the reader's eye moves from left panel to right
- Back cover — contact details, website URL, QR code and call-to-action. Many readers flip to the back immediately — make sure everything they need to get in touch is there
For tri-fold leaflets, the panel that folds inside (the right-hand outer panel) is seen first when the leaflet is partially opened. This is prime real estate — often used for a strong opening offer, a key benefit or a compelling image that encourages the reader to open fully.
Don't Design Across Fold Lines Carelessly
Images and design elements that span a fold line can create a powerful visual effect — but only if the fold is perfectly consistent, which it never quite is. Minor variations in folding position mean that continuous elements (a horizon line, a face, a geometric shape) that cross a fold will almost always show a slight misalignment on the finished piece.
The safest approach is to treat fold lines as hard boundaries and design each panel as a self-contained visual unit. If you do design across a fold, choose imagery where minor misalignment won't be noticeable — abstract backgrounds, gradients and textures are more forgiving than architectural lines, faces or precise geometric shapes.
Size Options
Folded leaflets are available in a range of sizes. The most common formats are:
- DL (99×210mm folded) — the most popular size for tri-fold leaflets. Fits standard C5 and DL envelopes for direct mail. Compact and easy to distribute
- A5 (148×210mm folded) — a versatile mid-size. Works well as a bi-fold for menus, programmes and simple brochures
- A4 (210×297mm folded) — the largest standard folded leaflet size. More space for detailed content, photography and complex layouts
- Square formats — distinctive and modern. Popular with lifestyle brands and creative businesses
Paper Stock and Finish
Paper choice significantly affects both the feel and the function of your folded leaflet:
- 130gsm silk or gloss — the most popular choice. Vibrant colour, professional feel, folds cleanly. Good for most marketing leaflets and brochures
- 170gsm silk or gloss — heavier and more substantial. Better for premium brochures and gate fold pieces where a more impressive physical presence is needed
- Uncoated — natural, tactile, writeable. Popular with eco-focused brands and designs with an organic or craft aesthetic
- Laminated cover — for folded leaflets with a separate cover stock, matt or gloss lamination adds durability and a premium finish
Note: very heavy stocks (250gsm+) can crack along fold lines on smaller fold formats. For tight folds, stick to 170gsm or below for the folding sheet.
Typography and Layout Tips
- Use a consistent grid across all panels — consistent margins and alignment create cohesion across the full leaflet
- One primary message per panel — each panel should have one job. Trying to communicate everything on every panel results in nothing being communicated effectively
- White space is not wasted space — panels with breathing room look significantly more professional than panels crammed with text and images
- Maximum two fonts — one display font for headings, one clean font for body text. See our guide: Typography and Fonts: Essential Tips for Effective Print Materials
Artwork Setup
- Supply as spreads — not single pages. See our guide: How to Set Up Spreads for Print
- Bleed: 3mm all round the outer edges of each spread. See our guide: What is Bleed and Safe Zone?
- Safe zone: 3mm inside all outer trim edges, plus a comfortable margin either side of internal fold lines
- Resolution: 300dpi minimum. See our guide: Understanding DPI for Print
- Colour mode: CMYK. See our guide: What is CMYK and Why Does it Matter?
- Format: PDF with fonts outlined or embedded
- Proof check: Print a reduced copy and fold by hand to check content flow before submitting. See our proof checking guide
