# Field of View and Reading Distances

There is a range of reading distances available for different code sizes.

Working Distance | Horizontal Values | Vertical Values
--- | --- | ---
Z1 = 15 mm | X1 = 6.4 mm | Y1 = 4.09 mm
Z2 = 210 mm | X2 = 148.31 mm | Y2 = 94.67 mm
Z3 = 420 mm | X3 = 301.14 mm | Y3 = 192.22 mm

Distances in mm / 1D min code | Distances in mm / 2D min code
--- | ---
25-105 | 5 MIL | 15-70 | 5 MIL
25-158 | 7.5 MIL | 15-105 | 7.5 MIL
25-210 | 10 MIL | 15-140 | 10 MIL
25-420 | 20 MIL | 15-275 | 20 MIL

Note: Due to tolerances, ranges can vary by +/- 5 mm for small codes to +/- 2 centimeters for large codes.
