How to Make a Brochure That Folds Properly

A brochure is not a hard document to design. It is a hard document to fold, and almost every home-made tri-fold fails for the same reason: the three panels were made the same width. They cannot be. The panel that folds inward has to travel a shorter distance around the crease than the two panels wrapping around it, so at equal widths it buckles and the brochure springs open on the table. Here is how to get the fold right first, and then everything else.

We build a page-layout app, so we see a lot of brochures arrive at the printing stage already broken: a headline sliced by a crease, an inside spread printed upside down, a front cover that turns out to be on the back. None of that is a design problem. It is geometry, and it takes ten minutes to solve before you type a word.

Step one: pick the fold, not the design

The fold decides the panel count, the panel widths and the order a reader meets your content. Choose it first. Three cover almost every job.

A tri-fold rolls in on itself: one panel tucks inside, the next wraps around it. The classic rack brochure, and the one with the width problem. A bi-fold is a single crease down the middle, so both panels are the same width and there is no maths at all. If a bi-fold covers your content, take it.

A Z-fold goes in alternating directions like a concertina. Six panels again, but because nothing wraps around anything, all three panels can be equal. It opens into one continuous strip, which suits a timeline or a numbered process far better than a tri-fold, though it racks and stacks badly.

Metric equivalents are the same shapes on a different sheet: A4 landscape is 297 × 210 mm, giving tri-fold panels around 99 × 210 mm. If your file might cross between the two systems, our breakdown of A4 versus US Letter covers what shifts, because every fold line moves when the sheet does.

Step two: the unequal-panel rule

This is the part nobody tells you, and it is why home-made brochures do not close.

Fold a strip of paper into three and look at it edge-on. The outer panel wraps around the thickness of the panel beneath it, so the inner panel, sitting inside that wrap, has a shorter distance to travel — by roughly the thickness of the paper at each crease. Give all three an identical width and the inner panel’s free edge runs into the opposite fold. The brochure bows, will not sit flat, and pops open in the rack.

The fix: make the inward-folding panel about 1.5 to 3 mm narrower than the other two. Thin paper needs the lower end of that range, heavy card the upper end. Numbers that add up exactly:

On Letter, the naive split is 11 ÷ 3 = 3.667 in per panel. The corrected split takes 1/16 in (1.59 mm) off the flap and shares it between the other two: 3.625 / 3.6875 / 3.6875. A difference you will never see and always feel.

The panel order that trips everyone up

On the outside sheet, reading left to right, the panels are not cover, middle, back. They are:

The inside sheet, left to right, is simply the three panels of the inside spread.

Why the front cover ends up on the right: with the inside face up, fold the right-hand third inward first, then the left-hand third over it. Flip the stack and the front cover is on top, the back cover underneath, the narrow flap tucked inside. The reverse of the outer-left panel is the inner-right panel, which is why the left-hand outside panel is the one that ends up hidden.

Do not take our word for it, or a template’s. Fold a blank sheet and number the panels in pencil. Fold a plain sheet exactly as the brochure will fold, open it flat, and write 1 through 6 on the faces in the order a reader meets them. That scrap of paper is your map for the rest of the job, and it costs thirty seconds.

Step three: what belongs on each panel

A tri-fold is not one design with six slots. It is four different jobs.

• Front cover. One promise and one image. That is the whole brief. A cover with four competing messages reads as none, and 3.6 in fills up faster than you expect.
• Inside flap. The first panel a reader sees when they lift the cover, and the most under-used surface in the format. Put the hook here: the one reason to keep reading.
• Inside spread. All three inside panels are visible at once when the brochure is fully open, so treat them as one canvas, not three columns. A photograph or a colour band can run right across. Keep a consistent baseline so text lines up across the creases.
• Back panel. The practical one. Address, phone, email, website, hours, a small map, and one clear instruction for what to do next. If it will be mailed, the address block sits here, so keep the lower half clear.

Step four: margins and safe area

Three numbers, and they save most of the disasters.

1. 0.25 in (6 mm) minimum from every fold line. Folding machines and human hands both drift. Text sitting 2 mm from a crease will look crooked on half the run.
2. 0.5 in (12 mm) minimum from the outer trim edge. Most desktop printers cannot print closer than about 6 mm to the paper edge anyway, and a shop trims a little unevenly.
3. Never run a headline across a fold. Body text crossing a crease is survivable. A 40 pt headline broken by one looks like a mistake even when the fold is perfect, because the crease casts a shadow through the letterforms.

Photographs and colour panels are the exception: a fold through a picture reads as intentional. Only type suffers.

Step five: setting up the page in the tool you actually have

The page setup is the same everywhere: Letter or A4, landscape orientation, and vertical guides at the panel boundaries. On a Letter tri-fold with the trimmed flap, those guides go at 3.625 in and 7.3125 in from the left edge. Set them once and design against them.

Here is how the common tools compare for this specific job.

Microsoft Word

Word will do this properly, and its unequal-column control is genuinely the right tool. Templates exist under File, New, search “brochure”, but many of them use three equal columns, so check before you trust one.

1. Layout, Orientation, Landscape.
2. Layout, Margins, Custom Margins. Set all four to 0.5 in.
3. Layout, Columns, More Columns. Choose three columns and untick “Equal column width”. This is the step that makes or breaks the brochure.
4. Enter the widths below. Word measures the text column, not the panel, so these numbers already have the fold margins subtracted. The 0.5 in spacing between columns is two 0.25 in fold margins meeting at the crease.

5. Type your outside content. To jump from one panel to the next, press Ctrl + Shift + Enter for a column break rather than hammering the Enter key, which will unravel the moment you edit anything above it.
6. Insert a page break for page two, the inside. The column settings carry over.
7. File, Save As, PDF (or Export, Create PDF/XPS).

Where Word breaks: text boxes drift, because by default they anchor to a paragraph that moves when you edit. Select each one, open Layout Options and fix the position on the page. Columns also reflow the whole document when you change a font size, so lock your type sizes early. And Word gives you no bleed and no crop marks, which matters only if a shop is trimming the sheet.

Google Docs

Docs is free, collaborative and the weakest of the lot at precise panels. The reason is specific: Google Docs cannot set unequal column widths. The Columns tool gives you a single uniform spacing value and nothing else. So the honest route is a three-column table, where the widths can differ.

1. File, Page setup. Landscape, page size Letter, and set all four margins to 0.25 in.
2. Insert, Table, 3 × 1.
3. Click into each column, then Format, Table, Table properties, Column width, and set: 3.375 in, 3.6875 in, 3.4375 in. Those add to 10.5 in, which is the text area, and they land the folds exactly on the panel boundaries once the page margins are counted.
4. In the same Table properties panel, set Cell padding to 0.25 in. That gives you the quarter-inch fold margin on every side and a half-inch outer margin, automatically.
5. Set the table border to 0 pt so the grid does not print.
6. Repeat the table on page two for the inside spread.
7. File, Download, PDF Document.

Where Docs breaks: overfill a cell and the whole table jumps to a new page rather than clipping, images fight the anchoring model, and there is no way to view the two sides together. For a school project due tomorrow it works fine. It is not a layout tool.

PowerPoint and Google Slides

Underrated for this. Both give you a free-placement canvas at a custom page size, which is closer to how a brochure actually works than a text flow is.

In PowerPoint: Design, Slide Size, Custom Slide Size, set 11 in × 8.5 in. In Google Slides: File, Page setup, Custom, 11 × 8.5 inches. Slide one is the outside, slide two the inside. Turn on guides (View, Guides in PowerPoint; View, Guides, Add vertical guide in Slides), place vertical guides at 3.625 in and 7.3125 in, then drop text boxes and images wherever you want them. Export with File, Save As, PDF or File, Download, PDF. One thing to check in PowerPoint first: File, Options, Advanced, tick “Do not compress images in file”, or your photos reach the printer at screen resolution.

Canva

A browser tool with a very large template library, which is the real draw. Set a custom size of 11 × 8.5 in, or start from one of its tri-fold templates, which come with fold guides in place. Placement is free-form, so unequal panels are no trouble. The costs: it needs an account, your document lives on their servers rather than your machine, and a portion of the templates, fonts and features sit behind a paid plan. If you want to start from something that already looks finished, that trade is often worth it.

A page-layout app

Word processors flow text; page-layout apps place objects at coordinates. For a brochure that is the difference between fighting the tool and using it. Anything in this category (Korva, Affinity Publisher, Scribus) gives you exact object positions, real guides, master pages so the panel structure repeats on both sides, and a PDF export carrying crop marks and bleed. Our rundown of desktop publishing software compares them properly.

On our side: Korva ships a Tri-Fold Brochure template alongside flyers, posters and menus, has Letter and A4 page-size presets and snaps objects to page edges, centres, margins and other objects. It runs offline on Windows, macOS and Linux with no account. A new user can repeatedly export one complete project; Pro is a one-time US$49 rather than a subscription.

Step six: the paper

This is where a good design becomes a cheap-feeling object, and it is entirely avoidable.

Copier stock is the single most common reason a brochure feels like a handout: ink from the back shows through, the sheet flops in the hand, the fold ends up soft rather than crisp. Move up to 120 gsm and the same design reads as a different budget.

Three details that matter more than people expect:

• Score before folding anything above roughly 170 gsm. A heavy or coated sheet has a brittle surface. Fold it cold and the coating cracks along the crease in a white line, especially ugly where the fold crosses a dark colour. Scoring crushes a channel first so the fibres bend instead of splitting. A print shop does this as a matter of course; at home, a bone folder and a ruler will do.
• Fold with the grain. Paper fibres run in one direction. Fold parallel to the grain and the crease is clean and straight; fold across it and the edge goes ragged. Bend a corner both ways — the direction that gives more easily is the grain.
• Matte, silk or gloss. Gloss makes photographs sing and shows every fingerprint. Matte reads better at arm’s length and takes a pen, which matters for anything with a form or a sign-up. Silk sits between the two and is the safe default.

Step seven: printing and export

Two mistakes account for nearly all reprints.

Get the duplex flip right. When you print double-sided, the driver asks whether to flip on the long edge or the short edge. For a landscape brochure sheet, choose flip on short edge. The long edge of a Letter sheet is the 11 in side, which on a landscape design is the top and bottom of your artwork, so flipping about it turns the inside upside down. Choosing “long edge” out of habit — it is the default, and it is correct for ordinary portrait documents — is the single most common brochure printing error.

Export a PDF, not the source file. Never hand a .docx or a .pptx to a print shop, and do not print one from a machine other than the one that made it. Fonts substitute, spacing reflows, column positions shift — which for a brochure means the fold lines move. A PDF freezes all of it. Print at 100 percent or Actual size, never “Fit to page”, which rescales the sheet and drags every fold measurement with it.

Bleed and crop marks matter only when someone else is trimming. At home you cannot bleed at all, because desktop printers leave an unprintable border, so design to a white margin and be done. For a print shop, or artwork running to the edge of the finished piece, you need bleed — usually 1/8 to 1/4 in past the trim line — plus crop marks showing where to cut. Ask the shop before you export; most have a one-line spec.

Korva’s export covers the shop case with a “Print shop” preset producing composite CMYK with crop and trim marks and a quarter-inch bleed margin, plus a “Pack and Go” option that zips the editable document, the press-ready PDF, full-resolution pictures and a README naming which fonts embed and which get substituted. It does not do colour separations, spot colours, ICC profiles or PDF/X, so a commercial press with a strict spec sheet needs dedicated prepress software. For a rack brochure at a local printer, the composite is what they expect.

A quick checklist

• Fold chosen before design started, and a pencil-numbered blank dummy on the desk
• Page set to Letter or A4, landscape
• Inward-folding panel 1.5 to 3 mm narrower than the other two
• Panel guides at 3.625 in and 7.3125 in (Letter) placed and locked
• Nothing within 0.25 in of a fold, nothing within 0.5 in of the trim
• No headline crossing a crease
• Front cover carries one promise; back panel carries contact details and a next step
• 120 gsm or heavier, scored above 170 gsm
• Exported as PDF, printed at 100 percent, duplex flipped on the short edge

Get the fold right and the rest of a brochure is ordinary layout work. Get it wrong and no amount of good typography rescues a sheet that will not close. If a single-sheet piece would serve you better, our guide to making a flyer covers that format, and if you produce something folded weekly, the fold and margin advice in our free church bulletin templates roundup applies here too.
