Create a tri-fold brochure →Design tips
A standard tri-fold brochure is 11×8.5 inches (279.4×215.9mm) unfolded, creating three panels of approximately 3.67×8.5 inches each. At 300 DPI, the full unfolded canvas is 3300×2550 pixels. Tri-folds are the most common brochure format for marketing materials, menus, and informational handouts.
- •Design at 3300×2550px (300 DPI) for the full unfolded sheet. Each panel is ~1100px wide.
- •The inner fold panel should be ~1/16" narrower than the outer panels to nest cleanly.
- •Design both sides as separate pages in your PDF. Include fold marks and 3mm bleed.
What you need to know
A tri-fold brochure starts as a single Letter-size sheet (11×8.5") printed on both sides, then folded twice to create six panels (three front, three back). The standard fold is a "letter fold" or "C-fold" where the right panel folds inward first, then the left panel folds over it. The inner right panel is typically 1/16" narrower to nest cleanly inside.
The six panels serve distinct purposes: the front cover (right panel of the front) is your first impression and should feature a strong headline and image. The back cover (left panel of the front) typically has contact information and a CTA. The interior panels tell your story — product features, service descriptions, or menu items.
When designing, account for the fold lines. Each panel is approximately 3.67" wide (3 11/16"), but the inner fold panel should be about 3.625" to prevent bulging when folded. Include 3mm bleed on all outside edges and mark the fold lines clearly in your file. Most print shops expect a single flat PDF with crop and fold marks.
