Sentence or Title Case for Labels?
"For those few of us who are deeply interested in forms, there’s nothing so fascinating as a subtle detail. Like, for example, the question that appeared in my email in-box earlier this month.
Martin McGuire wrote to me to ask 'How labels/captions for forms should be formatted'. As he points out, the ISO-9241 part 17 standard seems to recommend that the first letter of the word only is capitalised: It says that you should use: "Initial upper-case (capital) letter for field labels: To facilitate readability, the text field labels begin with an upper-case letter.
