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 are usually 1/32″ to 1/8″ smaller than the inner panels to allow for proper folding and nesting.
Also Known As: gatefolds
Examples: A doublegate fold might be used in the middle of a magazine for a fold-out center spread.
