What are good error messages?
Summary: Established wisdom holds that good error messages are polite, precise, and constructive. The Web brings a few new guidelines: Make error messages clearly visible, reduce the work required to fix the problem, and educate users along the way.
How long should error messages be?
Keep language clear and concise
The longer a message, the less likely your users will read them. In fact, an oft-cited study by the American Press Institute showed that shorter sentences results in greater understanding by users. So, when sentences were 14 words or less, users understood 90% of the messaging.
