Are there any guidelines for having space between the form elements (fields)?
You know a layout has good spacing when:
- Overall, the UI surface feels comfortable and doesn't feel cramped.
- The space appears uniform and balanced.
- Related elements are close together and unrelated elements are relatively far apart.
- There is no dead space between controls that are meant to be together, such as toolbar buttons.
I've read that the most commonly used space between the fields is the field height. You can use the space to develop some kind of pace in your form - if you want your users to fill in the fields carefully and slowly, make the gaps bigger and align the labels to the right. Of course these are just some general rules, so here comes the classic - DEPENDS OF THE PROJECT :)
