Learn how to create an 8.5x11 inch full-bleed brochure that folds correctly
To download our free trifold brochure template for Adobe InDesign
Tri-fold brochures are excellent marketing tools, but they can be a little tricky to set up. The three columns in a brochure are not the same size, so if you lay out your 8.5"x11" design with three equal 3.66 inch panels it won't fold correctly.
For most brochures, the inside panel must be smaller than the middle, and the cover must be larger. This allows for the panels to tuck in properly when folded. Generally 1.5mm is all that's required, so the inside flap would be 3.607", the middle panel would be 3.667", and the front cover would be 3.725".
In practice that would look like this:
the dotted lines represent where we'd fold the brochure
the solid lines represent the safe zone
the dashed lines represent where we'd cut the document
