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.
