A French fold brochure is folded once in one direction and then again at a right angle, creating four equally sized sections in the folded piece. That compact format can reveal a surprising number of production problems: cracking across a dark design, panels facing the wrong way, an unexpectedly bulky fold or artwork shifted by an incorrect template assumption.
The safest approach is to select the printer and finished format first, download the exact template, and then choose a paper whose thickness, stiffness, surface and grain suit two intersecting folds. Do not choose from the pound label alone.
What makes a French fold different?
PrintRunner describes its French Fold option as one horizontal fold and one vertical fold, resulting in four equal panels. It lists this separately from a double-parallel fold, which uses two successive folds running parallel to each other.
The terminology is not perfectly standardized. An industry glossary describes a French fold as a one-sided sheet folded twice at right angles to make an uncut four-page section, while commercial printers may apply the name to a brochure option with their own orientation and finishing setup. The printer’s current template therefore matters more than a generic diagram found elsewhere.
This is also why flat size and folded size need explicit labels. PrintRunner provides templates for multiple French-fold sizes, but its size presentation leaves room for ambiguity about which dimensions describe the open sheet and which describe the folded result. Confirm the flat dimensions, finished dimensions, orientation, trim and fold positions in the downloaded template and order configuration.
Choose paper by behavior, not just weight
Paper weight and thickness are different properties. Basis weight describes mass using the basic sheet size assigned to a paper grade, while caliper describes physical thickness. Stiffness, bulk, smoothness and folding endurance are separate characteristics again, as outlined in TAPPI’s overview of physical paper tests.
Consequently, “100 lb” does not identify one universal thickness or folding behavior. Text and cover stocks use different basis-weight systems, and two papers carrying similar weight labels can differ in caliper, density and stiffness. See the distinction between paper caliper and paper weight before treating a package label as a folding specification.
When checked, PrintRunner’s brochure configurator offered French folding with 70 lb uncoated, 80 lb glossy, 100 lb glossy, 100 lb matte, 10 pt glossy cardstock and 10 pt matte cardstock. It stated that the listed paper and cardstock options would arrive folded, with the 10 pt cardstock scored before folding. These are provider-specific options rather than universal recommendations, and availability should be confirmed when ordering.
| Stock characteristic | Likely production consequence | What to verify |
|---|---|---|
| Lighter or more pliable sheet | Usually forms a less bulky folded piece | Opacity, feel and resistance to repeated handling |
| Thicker or stiffer sheet | More body, but greater stress at both folds | Caliper, grain direction and scoring method |
| Gloss-coated surface | Brighter-looking reproduction but limited writability | Fold cracking, glare and whether writing is required |
| Matte or uncoated surface | More subdued appearance; some surfaces are easier to write on | Actual writability, scuff resistance and color result |
PrintRunner characterizes its 70 lb uncoated option as writable and easy to fold, its glossy stocks as having limited writability, and its 100 lb matte option as a subdued surface intended for repeated handling. Those descriptions apply to the provider’s named offerings. For a broader decision, compare coated and uncoated paper by appearance, handling, writability and finishing requirements.
Two fold axes complicate grain direction
Paper generally folds more willingly with the grain—that is, with the fold running parallel to the predominant fiber direction. Scoring creates a controlled line where the sheet should bend and is especially relevant to thicker stocks.
A French fold introduces an unavoidable complication: its two fold lines are perpendicular. Both cannot run parallel to a single grain direction. One fold will therefore be cross-grain unless the construction or process differs from a conventional sheet. The printer must decide which fold receives the more favorable grain relationship and how the score pattern and folding sequence should be handled.
Sappi’s technical guidance on fold endurance identifies sheet pliability, fiber strength and delamination at the score as important to foldability. It also notes that coated sheets and heavier basis weights can be more vulnerable to cracking, particularly with cross-grain folds, inadequate scoring, heavy dark coverage or brittle topcoats.
This does not mean every French fold needs cardstock, or that coated paper will inevitably crack. It means the risk depends on the actual paper, coating, caliper, grain, ink coverage, scoring process and folding sequence. If the design uses a heavy solid across a fold, ask for a folded production proof rather than approving only a flat color sample.
Scoring matters most when the sheet resists bending
A score or crease gives the material a controlled place to bend. It cannot make an unsuitable sheet suitable, but it can reduce random surface breakage and produce a more predictable fold. PrintRunner specifically states that its 10 pt glossy and matte brochure stocks are scored before folding.
Discuss scoring whenever the brochure uses substantial caliper, a coated surface, dense ink coverage or artwork that crosses a fold. The practical distinction between scoring and creasing can vary with equipment and trade usage, so specify the required result rather than relying only on vocabulary. The goal is a clean fold with minimal cracking, not a debate over what the machine operator calls the line. Our guide to scoring and creasing cardstock explains the variables in more detail.
Build the file from the selected printer’s template
A French-fold file has inside and outside relationships that are easy to misread on a flat screen. Rotation introduced by the second fold can leave a panel upside down or place a cover on the wrong face. Begin with the printer’s blank template and identify the trim boundary, both fold axes, the outside face, the inside face and the final cover before placing artwork.
Do not import a universal bleed amount, safe distance or fold tolerance from an unrelated brochure guide. Those values depend on the provider’s production specification. Keep critical text and small logos away from fold lines according to the supplied template, and inspect artwork crossing either fold at full size.
- Choose the printer, finished size, orientation and fold option.
- Download the template attached to that exact configuration.
- Mark the final cover, back and interior areas with a temporary paper mock-up.
- Confirm whether the displayed dimensions are flat or folded.
- Select paper using caliper, stiffness, surface and foldability—not the weight label alone.
- Ask how grain, scores and fold sequence will be handled, especially for cardstock.
- Review a folded proof when alignment or cracking would materially affect the design.
The practical specification
A successful French fold brochure is not simply a normal brochure with one extra bend. Specify it as a coordinated system: exact template, flat and finished dimensions, paper identity, caliper, surface, grain, score method, fold sequence and artwork coverage. If handwriting matters, start with an uncoated or verified writable surface. If visual punch matters more, a coated stock may suit the design, but scrutinize artwork crossing both folds.
Above all, approve the folded object rather than judging only the flat sheet. Two right-angle folds turn small assumptions about paper and panel orientation into very visible mistakes. Paper has a sense of humor about that, and it is usually expensive.
