Definition: In double gatefolds there are three parallel folds. The left and right edges of the paper fold and meet in the middle, without overlapping, along a center fold.
The outer panels (the ones that fold in to the middle) are usually 1/32" to 1/8" smaller than the inner panels (the ones covered by the panels that fold in) to allow for proper folding and nesting.
Also Known As: gatefold
Examples: A doublegate fold might be used in the middle of a magazine for a fold-out center spread.
