Forms should never consist of more than one column. One of the problems with form fields in multiple columns is that your users are likely to interpret the fields inconsistently. If a form has horizontally adjacent fields, the user must scan in Z patterns, slowing the speed of comprehension and muddying the clear path to completion. But if a form is in a single column, the path to completion is a straight line down the page.

Issues w/ Multi-column

• Users omit fields
  Because they do not notice them or because they misinterpret the meaning of the multiple columns, or
• Fill out unrelated or incorrect fields
  Because they misinterpret them to be part of the needed input.

Exceptions

One exception is for information users expect to see in a single line like:

• Our first, middle, last name: Sebasteean van Derlot
