Many of the more common folds are shown in the following diagrams. Certain folds require "short panels" to allow the finished piece to remain flat. The short panels are identified on the pictures below. The amount of trim for the short panels will depend upon the weight and type of stock used in your project, but a safe measurement is 1
th of an inch. Use the supplied panel dimensions and dimension calculators to help make sure your project folds correctly. For specific information about your project, contact your Sales or Customer Service Representative.
Quick Jump: Letter Fold | Double Parallel Fold/Gate Fold | Roll Fold
11 x 17 (tabloid size)
81/2 x 11 (letter size)
81/2 x 14 (legal size)
When doing a trifold
, divide your paper width by 3 (ie, on an 81
x 11 sheet, divide 11 by 3 to get 3.6667). Round that number up
to nearest 32nd of an inch (ie, 3.6875). This number will be the size of your two wide panels. To get third third (short) panel, subtract a 16th, or .0625 from the wide panel size (ie, 3.625). The form below will do the work for you, but, since trifolds work with thirds (uneven numbers), the measurements are not always exact (ie, if you add the three numbers together, the sum does not exactly equal the original size). The results are
extremely close and are usable.
Double Parallel Fold/Four-Panel Gate Fold
Double Parallel Fold
When doing a four panel double parallel fold
or four panel gate fold
, two of the panels are wide and two short. Divide your width by 4 (ie, 17 divided by 4 is 4.25). Add a 32nd, or .03125, to the number to get your wide panel size (ie, 4.28125). Subtract a 16th, or .0625, from the wide panel size to get your short panel size (ie, 4.21875).
Four panel roll folds
have two panels that are the largest size, a short panel, and an even shorter panel. Divide your width by 4 (ie, 17 divided by 4 is 4.25). Add a 16th, or .0625, to the number to get your wide panel size (ie, 4.3125). Subtract 3
nds, or .09375, from that number to get the short size (ie, 4.21875). To get the final, even shorter size (the shortest size), subtract another 16th, or .0625 (ie, 4.15625). This actually makes the difference between the two large panels and the short panel 3
s instead of a 16th, but that's only a 32nd of an inch difference.
