PDF417 Structure

  • W : the width of PDF-417
  • Q : the width of the quiet zone; Qmin=2X
  • R : umber of rows in the symbol (3<=R<=90)
  • C : number of columns in the symbol in the data region (excluding start, stop and row indicator codewords) (1<=C<=30)
  • X : the width of a module bar; Xmin=1 pixel
  • Y : module height (also called row height) (Ymin=3X)
  • H : height of symbol



PDF417 Barcode Width

The width W of a PDF417 symbol, including quiet zones, is determined by you module width and number of columns.
It can be calculated from the following expression:


W = 2Q + 17X*4 + X + 17CX


Then the minimum value of W can be calculated as below:


Q min = 2X.
W min = 72 X + 17 CX
If, X min = 1, W min = 17C + 73

Eg. PDF417 data = " PDF417 ", X=1, left margin=2, right margin=2, C = 5, and other settings in default.
W min = 73 + 17*5 = 158 pixel



PDF417 Barcode Height

The height of a PDF417 symbol, including quiet zones, is determined by module height and number of rows.
It can be calculated from the following expression:


H = 2Q + RY        (Y >= 3X, Q >= 2X)


Then the minimum value of H, including horizontal quiet zones, can be calculated as below:


Q min = 2X, Y = 3 X
H min = 2*2X + R*3X
= 4X + 3RX
If, X min = 1, W min = 4 + 3R

Eg. PDF417 data ="PDF417", X = 1 , top margin = 2, bottom margin = 2, and other settings in default (R = 3).
H = 4 + 3*3 = 13 pixel
