FDT - Minimum size and spacing for user areas

What is the minimum size and spacing for user areas?

If you create check boxes and user areas in a form you should be aware that:

  • Very small user areas will be hard to match with pen strokes
  • Two boxes placed too close to each other could cause a “hit” in the wrong box when matching strokes with the PAD file
  • Recommended minimum size of user area is 4x4 mm and recommended minimum spacing between user areas is 2 mm.
    You can use smaller sizes and spacing but you need to make sure the final product functions properly for different type of users.
