Whether you are briefing a designer or setting up your own artwork, the fold type you choose affects every decision that follows: panel count, content hierarchy, paper weight, and how the finished piece sits in a rack or an envelope. This guide covers the four main brochure formats available in Australia, with flat and finished sizes, panel layouts, and clear guidance on which fold suits which brief.
CHEAT SHEET
- DL tri-fold (A4 folded to DL) is the most common AU business brochure and fits a standard DL envelope
- A5 bi-fold (A4 folded in half) gives you 4 large panels, ideal for catalogues and service menus
- Z-fold opens flat from both ends, making it practical for self-mailers and sequential storytelling
- Gate-fold creates a dramatic reveal and suits premium brand pieces, product launches, and events
- 150gsm gloss is the go-to stock for most brochures; step up to 250gsm for a premium feel
The Four Main Brochure Fold Types: A Quick Comparison
Not all folds behave the same way in the hand or on the press. Here is how the four common formats stack up. For a panel by panel walk through of each fold, including the gate fold and the roll fold, see Tri-Fold, Gate-Fold and Z-Fold Brochures: A Fold Guide.
| Fold type | Flat sheet size | Finished size | Panels | Best for |
|---|---|---|---|---|
| A5 Bi-fold | A4 (210 x 297 mm) | A5 (148 x 210 mm) | 4 | Service menus, capability statements, product catalogues |
| A4 Bi-fold | A3 (297 x 420 mm) | A4 (210 x 297 mm) | 4 | Annual reports, detailed product guides, exhibition handouts |
| DL Roll Tri-fold | A4 (210 x 297 mm) | DL (99 x 210 mm) | 6 | Rack cards, travel brochures, business information, DL mail campaigns |
| DL Z-fold (Tri-fold) | A4 (210 x 297 mm) | DL (99 x 210 mm) | 6 | Self-mailers, step-by-step guides, trade show handouts |
| Gate-fold | Custom flat size | Varies | 6+ | Premium reveals, product launches, event invitations, luxury brands |
A quick note on terminology: “tri-fold” always refers to a sheet folded into three sections (six panels including front and back). The two common tri-fold variants differ in how those folds land: a roll fold (sometimes called a letter fold) has the inner panel folded inward, while a Z-fold alternates direction so it opens accordion-style from each end.
Bi-Fold Brochures: Sizes, Panels and When to Use Them
A bi-fold is a single sheet folded once down the centre, creating four panels of equal width. It is the simplest format and the easiest to design for because there are no overlapping panels to account for.
A5 Bi-fold (A4 sheet)
Flat size: 210 x 297 mm. Finished size: 148 x 210 mm.
Each of the four panels measures approximately 148 x 148 mm. This is a generous amount of real estate per panel, which makes the A5 bi-fold a strong choice for:
- Service menus and hospitality inserts
- Real estate capability statements
- Health and wellness clinic guides
- Product catalogues with multiple images per page
The A5 finished size also slots neatly into A5 envelopes and display stands. Because the panels are square-ish in proportion, designers can use bold full-bleed imagery without it feeling cramped.
A4 Bi-fold (A3 sheet)
Flat size: 297 x 420 mm. Finished size: 210 x 297 mm.
Four panels at A5 each. This is the largest standard brochure format and works best when you genuinely need the space, for example:
- Detailed product or technical specifications
- Event programmes
- Annual or sustainability reports
- Corporate capability documents
The A4 finished size is familiar and easy for recipients to file or archive, but it is larger to mail and does not fit DL racks. If rack distribution is part of your plan, a tri-fold is the more practical choice.
Tri-Fold Brochures: Roll Fold vs Z-Fold
Both tri-fold variants start from the same A4 flat sheet (210 x 297 mm) and finish at DL (99 x 210 mm). The difference is structural: how the inner panel folds, and what that means for design.
DL Roll Tri-fold (Letter Fold)
This is the most common brochure format sold in Australia. The sheet folds in thirds, with the right-hand panel tucking inside the left-hand panel. The result is a tidy six-panel piece that fits perfectly in a standard DL rack, a DL envelope, or a pocket folder.
Panel widths are not all equal. The inner panel (the one that tucks inside) must be 2-3 mm narrower than the two outer panels, otherwise it will buckle when folded. A standard layout on an A4 sheet might be: outer left 100 mm, outer right 99 mm, inner panel 98 mm (with 3 mm bleed added to the flat size).
Design considerations for roll tri-folds:
- The front cover is the right-hand panel when the sheet is flat (the outermost face)
- The back cover is the left-hand panel
- The inner panel (narrower) is the first thing a reader sees when they open the brochure, so it earns a strong hook or key call to action
- Keep critical content at least 5-6 mm clear of each fold line
DL Z-Fold (Accordion Fold)
The Z-fold alternates direction: fold one goes right-to-left, fold two goes left-to-right, creating a Z shape when viewed from the side. Because the panels fold away from each other rather than inside each other, all six panels can be equal width.
Z-fold brochures open from both ends independently, which makes them useful for:
- Step-by-step or numbered sequences (each panel is a distinct step)
- Self-mailers (the back panel can be addressed and posted without an envelope)
- Trade show pieces where the brochure needs to stand upright accordion-style
Unlike the roll fold, a Z-fold will not close as compactly on its own. If you need the finished piece to stay shut, a belly band or a glue dot is a common finishing option.
Paper Stock and GSM: Which Weight to Choose
Paperlust Print Shop offers five paper options for brochure printing, all suited to full-colour digital offset production:
| Stock | Weight | Finish | Best use |
|---|---|---|---|
| Gloss | 115 gsm | High sheen | Budget runs, internal documents, event handouts |
| Gloss | 150 gsm | High sheen | Most business brochures, rack cards, hospitality |
| Gloss | 170 gsm | High sheen | Retail, real estate, premium feel without heavyweight cost |
| Matte | 170 gsm | No sheen | Corporate reports, photography-led pieces, text-heavy content |
| Gloss | 250 gsm | High sheen | Luxury brands, high-end retail, product launches |
The 150 gsm gloss is the most popular choice for everyday brochure printing. It holds colour vibrancy well, folds cleanly, and sits within a budget that works for mid-to-large runs. If your brochure is photography-forward and you want images to pop, 170 gsm gloss adds a perceptible quality lift without a significant cost increase.
Matte 170 gsm is the go-to for anything that prioritises readability over sheen: legal or financial services, text-dense technical guides, and contexts where glare would be a problem (such as healthcare waiting rooms with overhead lighting).
For premium pieces, 250 gsm gloss gives a card-like stiffness. At this weight a bi-fold in particular feels closer to a greeting card than a standard handout, which can be effective for product reveals or premium event collateral.
Note that lighter stocks (115-150 gsm) can show slight show-through on heavy ink coverage. If your design has large dark panels on both sides of the same section, step up to 170 gsm or brief your designer to offset the dark blocks.

Design Tips: Setting Up Artwork for Brochures
Getting the file setup right before you send to print saves time and avoids costly remakes.
Essential artwork requirements
- File format: PDF, SVG, or Adobe Illustrator (.ai) files are preferred
- Bleed: Include 3 mm bleed on all edges, with crop marks
- Fonts: All fonts must be outlined (converted to curves) before export
- Images: Embed all linked images; do not supply separate image files
- Dieline: If your artwork requires a custom dieline, supply it on a separate layer in 100% Magenta Spot Colour
Fold-line design rules
The most common brochure print problem is content that runs too close to a fold line. A fold is never perfectly precise across a full production run, so a 5-6 mm safe zone on either side of each fold line is the practical minimum. Text, logos, and critical visual elements that cross a fold line will look misregistered on the finished piece.
For roll tri-folds, the narrower inner panel is a frequent pain point. If your designer sets all three columns at equal width in the layout, the inner panel will buckle when folded. Make sure the inner panel is 2-3 mm narrower before you submit files.
Checking colour and finish on screen
Gloss stocks render colours with higher saturation and contrast than matte. If you proof a design on screen and then print on matte 170 gsm, expect the output to look slightly softer and cooler. This is normal. If colour accuracy is critical (brand colours for a corporate document, for example), request a physical proof run before committing to the full quantity.
When to Choose a Booklet Over a Brochure
A brochure is the right tool when your message fits on a single folded sheet and you want something that distributes easily and costs little per unit. But some briefs genuinely need more space.
Signs you may need a booklet instead:
- You have more than 8-12 content panels worth of information
- You need a table of contents or chapter navigation
- The finished piece needs to lay flat when open (a booklet does this more reliably than a brochure)
- You are producing a product catalogue with more than 20-30 items
- The document needs to be filed or stored upright on a shelf
For those situations, A5 booklets from Paperlust Print Shop are a natural step up. Saddle-stitched booklets give you pages in multiples of four (8, 12, 16, 24, 32 pages), lay flat when open, and are as easy to distribute as a brochure. See Booklet Printing Australia: Saddle Stitch vs Perfect Bound for a full comparison of binding types and page count options.
Frequently Asked Questions
What is the most common brochure size in Australia?
The DL tri-fold is by far the most common business brochure format in Australia. It folds from an A4 sheet down to DL (99 x 210 mm), fits standard DL racks and envelopes, and gives you six panels of content. Because DL is a widely recognised size in AU direct mail, it also works well as a self-contained mail piece inside a DL envelope.
What is the difference between a roll fold and a Z-fold tri-fold?
Both start from an A4 sheet and finish at DL size with six panels. The roll fold (letter fold) has the inner panel tucking inside the outer panels, which means the inner panel must be 2-3 mm narrower to fold flat. A Z-fold alternates fold directions like a fan or accordion, so all panels can be equal width. Z-folds open from both ends independently, making them better for sequential content and self-mailers.
What paper weight should I use for a brochure?
150 gsm gloss is the most popular and practical choice for most brochure applications. It holds vivid colour, folds cleanly, and suits mid-to-large print runs without inflating cost. Step up to 170 gsm for a more substantial feel or for designs with heavy ink coverage, and to 250 gsm gloss for premium or luxury applications.
How do I set up artwork for brochure printing?
Supply a PDF, SVG, or Adobe Illustrator file with 3 mm bleed on all edges and crop marks included. All fonts must be outlined and all images embedded. If your design includes a custom dieline, place it on a separate layer filled with 100% Magenta Spot Colour. For tri-folds, ensure the inner roll-fold panel is 2-3 mm narrower than the outer panels to prevent buckling.
How long does brochure printing take?
Production time is 2-5 working days after your design proof is approved. A digital proof is sent before printing begins; once you approve it, production starts. If you have a deadline, contact Paperlust Print Shop when placing your order to discuss your timeline.
What is the difference between a brochure and a booklet?
A brochure is a single sheet folded to create panels (4 panels for a bi-fold, 6 for a tri-fold). A booklet is a multi-page document bound at the spine, typically with 8 or more pages. Brochures are lower cost per unit, easier to distribute in racks, and faster to produce. Booklets are better suited to longer content, product catalogues, and pieces that need to lay flat when open. If your content exceeds what comfortably fits on one folded sheet, an A5 booklet is likely the better fit.
