Custom Bi-Fold Brochure Printing
Bi-fold brochures suit company introductions and short product presentations with a cover and a broad inside spread. One central fold creates four reading panels.
- Simple reveal
- Connected inside spread
- Compact closed format
Illustrative product configuration
Product overview
Four panels with a clear center opening.
A single center crease creates four printed panels. The uninterrupted inside spread is useful for diagrams; the fold still interrupts fine rules or faces placed directly on it.
Simple reveal
One fold separates the cover from an inside spread without a nested tuck panel.
Connected inside spread
The opening creates a broad space for diagrams, imagery or related messages.
Compact closed format
The folded dimensions set the handout size while the flat sheet defines the design area.
Specifications & materials
Set the Closed Size and Four-Panel Layout
Start with flat width × height and closed width × height in mm. Then compare the material and construction choices below.
Use these options to prepare your specification. Material grades, weights, thicknesses and feasible dimensions are confirmed for the quoted construction. A paper weight is not a finished thickness or a strength rating.
| Parameter | Options or Information to Supply | Why It Matters |
|---|---|---|
| Finished dimensions | A4 flat → A5 closed: 297 × 210 mm; A3 flat → A4 closed: 420 × 297 mm | Flat-sheet references; nominal panel divisions exclude crease, tuck and closing allowances. The approved layout determines finished size. |
| Format and component count | Four panels; print on one or both faces of the sheet | One flat sheet carries both printed faces. Identify every outside and inside panel on the folded reading map. |
| Paper | Coated printing paper: 115 / 170 / 250 g/m² supplier-reference grades; uncoated alternative for writing | Named supplier examples, not stocked grades or production limits. Choose by opacity, image detail, stiffness and converted handling. |
| Fold | One central fold with four reading panels | Confirm outside and inside artwork orientation on a folded mockup. |
| Scoring and finish | Scoring and compatible coating or lamination as reviewed | Check the crease with the intended stock, print coverage and surface finish. |

Compare materials and construction
Choose around the intended use. These are alternatives to discuss, subject to the confirmed specification.
Lighter coated sheet
- Suitable for
- A compact four-panel handout.
- Check before selection
- Check opacity across panels and the feel of the single fold.
Heavier coated or uncoated sheet
- Suitable for
- A firmer presentation with one principal crease.
- Check before selection
- Request a crease sample around the paper grain and printed coverage.
Surface finish options
Printed sheet surfaces
Choose the sheen around viewing light and folding. A coating and a bonded film are different routes; confirm fold behavior, color and any writing area on the finished stock rather than assuming every sheet needs lamination.

Keep the Center Fold Clear and the Panels Aligned
Focus the review on front-to-back orientation, center-fold position and inside-spread alignment.
01 / SELECTION CHECK
Align content with the center fold
Set the closed dimensions and flat sheet together. Treat the center as a crease, keeping essential type and fine image detail outside its safety area. Check orientation on both sides.
02 / SELECTION CHECK
Score for the proposed material
Evaluate the selected stock, grain and any coating or film at the fold. Inspect the converted piece for cracking and closure; increased weight alone does not produce a better folded result.
Fold and panel engineering
Plan the flat sheet, center fold and reading order as one layout
A bi-fold brochure uses one central fold to create four reading panels. Its finished width is approximately half the flat width; confirm the fold direction, content sequence and safe area around the crease before artwork is released.
Compare dimensions and usable space
Published reference formats with their selection notes.
A4 flat → A5-sized closed · 297 × 210 mm
One fold makes two nominal 148.5 mm-wide panels; a compact closed format with a continuous inside spread.
Read every format’s selection note
- A4 flat → A5-sized closed: 297 × 210 mm. One fold makes two nominal 148.5 mm-wide panels; a compact closed format with a continuous inside spread.
- A3 flat → A4-sized closed: 420 × 297 mm. Nominal 210 mm closed width gives larger diagrams and images; folded dimensions exclude production allowances.
- Outside: back cover
- Outside: front cover
- Inside spread: two facing panels
Select the material by its finished behavior
For a folding sheet, compare coated 115 or 170 g/m² reference grades with an uncoated writing surface. A heavier sheet may need scoring and can change closing behavior. GSM measures mass per area, not caliper or foldability.
Production checks that prevent avoidable rework
Distinguish flat size from finished size
State both dimensions in the quote brief. The closed size describes handling and distribution; the open size determines the sheet and the room available for the inside spread.
Keep critical content off the fold
Avoid placing small type, faces, product edges or rules directly across the center crease. Use the approved layout template and allow for the selected stock's fold behavior.
Check grain and crease on the chosen stock
Paper grain and coating affect folding behavior. Review a folded sample on the specified stock; where the surface risks cracking, discuss scoring and fold orientation before production.
Use-case selection
Choose a configuration for the job it has to do
Compact sales handout
Use the cover to identify the offer and the inside spread for a clear comparison or product story.
Trade-off: The four-panel format limits detail; move specifications to a linked page or separate sheet.
Event or venue information
Keep opening instructions and essential details visible on the first open spread; put secondary references on the reverse.
Trade-off: A highly coated surface may be less convenient for handwritten notes.
Mail or counter distribution
Choose a closed size that fits the envelope, rack or counter space, then verify thickness and fold closure with a dummy.
Trade-off: A heavier stock feels more substantial but may affect postage and pack-out.
Problem → cause → solution
Resolve the failure points before production
The fold shows a pale cracked line
Why it happens: Coating and ink are stretched around a sharp fold; unsuitable grain or an unmatched crease increases stress.
How to prevent it: Make a converted sample on the intended stock and finish. Inspect the dark areas along each crease and adjust grain direction or scoring before releasing the layout.
The reverse reads in the wrong order
Why it happens: Outside and inside artwork were prepared without a folded panel map.
How to prevent it: Number the panels on a paper mockup, mark the front and reverse, and proof the fully folded piece.
Alternative formats
When another construction is a better fit
| Alternative | Structural difference | Selection trade-off |
|---|---|---|
| Roll-fold brochure | Two folds create a staged six-panel reveal. | Adds a tucked panel and a nesting allowance; less immediate than a broad inside spread. |
Sampling & production
Choose a Sample That Answers Your Main Concern
A structural sample, a print proof and a finished sample answer different questions. Confirm the sample scope before approval. Free samples are prepared within 15 days; courier arrangements and transit time are separate.
Structure and material sample
Review paper and fold with the proposed dimensions and component count. Agree whether the sample uses production materials or substitutes. An unprinted construction sample does not approve printed color.
Print and artwork proof
Review representative artwork at finished size on the agreed proof condition. Check fine detail and important colors. A screen proof cannot establish physical feel or the performance of the finished assembly.
Complete finished sample
Assess front-to-back orientation, center-fold position and inside-spread alignment with the specified components and finishing present. Record the approved revision and any differences to resolve before production.
How to Order Bi-Fold Brochure
Send your project brief
Send flat width × height and closed width × height in mm. Specify four panels; print on one or both faces of the sheet. State the number of finished folded brochures per design and language, delivery destination and required arrival date. Tell us which options are undecided.
Compare the quotation
Ask for pricing by finished folded brochures per design and language. Compare the same configuration at each quantity. The quotation should identify materials, finishing, sample scope, packing and freight, plus payment and order terms.
Review the right sample
Choose a sample that can demonstrate front-to-back orientation, center-fold position and inside-spread alignment. Confirm what the free sample includes and any differences from the intended production specification. Preparation is completed within 15 days; courier arrangements and transit time are separate.
Approve the production version
Confirm the specification, file revision and sample decisions in writing. Production scheduling follows the agreed approvals and order release conditions; changes may require a revised quote or schedule.
Confirm packing and delivery
Keep finished pieces folded squarely without excessive crease pressure. Bundle by version and protect the exposed cover faces against scuffing. Agree the destination and shipping arrangement, with production, dispatch and transit dates listed separately.
Details to Confirm in the Quotation
- Order unit and price breaks
- Specify finished folded brochures per design and language. Request the feasible minimum and quantity breaks for that exact configuration; a change of material, version or component count can change the price.
- Sample scope and delivery
- State whether you need a material trial, a print proof or a complete finished sample. Free samples are available, with preparation completed within 15 days. Confirm the included materials and processes; courier arrangements and transit time are separate.
- Approval and schedule
- State the required arrival date and whether versions ship together or to separate destinations. The quote must distinguish sample work, production and transit; a requested date is not a confirmed schedule.
- Packing and identification
- Keep finished pieces folded squarely without excessive crease pressure. Bundle by version and protect the exposed cover faces against scuffing.
- 01
Prepare outside and inside faces on the approved four-panel layout. Mark the center fold separately and keep orientation, bleed and crease safety consistent.
- 02
Use the PDF/X export preset and output condition confirmed with prepress. Embed fonts and identify the approved file revision.
- 03
Check continuous-tone images at about 300 effective pixels per inch (ppi) at their final placed size. Fine linework can require a different resolution or vector artwork.
- 04
Extend trim artwork by 3 mm unless the approved template specifies otherwise. Keep structural, folding and binding clearances separate from trim bleed.
- 05
Identify named spot colors or physical references and the intended substrate. Agree proof acceptance and keep finishing separations distinct. A screen PDF does not approve printed color.
Engineering & purchasing FAQ
Questions Before Ordering Bi-Fold Brochure
How many panels does a bi-fold have?
One fold creates two panels on each face, four in total. The inside opens as a paired spread. Identify outside and inside in the file so the cover and back panel are not reversed.
Can a photograph span the inside?
It can, with the crease kept in mind. Place critical detail away from the fold and inspect the actual stock and finish after conversion, particularly for large dark or solid-color areas.
Which sample should I request first?
Start with the uncertainty that could change the specification: front-to-back orientation, center-fold position and inside-spread alignment. If the concern is physical, request the relevant material or functional sample. If it is print appearance, agree a suitable proof. Confirm the sample scope before approval. Free sample preparation is completed within 15 days; courier arrangements and transit time are separate.
How should I state quantities for a quote?
Use finished folded brochures per design and language. Separate versions and give a delivery destination and required arrival date. This lets the quote distinguish the production quantity, packing and shipping scope.
