Provide checklists, As users complete your form, you may well be asking them to provide supporting information or attach supplementary documents where required. Providing a checklist, often at the beginning or end of a form, helps remind users about all the things they should remember to attach, and any further steps they need to go through.
Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters. Its similarly annoying to them when its a long free text box, making the customer question whether they are answering correctly and sufficiently. Providing response boxes that reflect the anticipated answer length and format reassures people that they are filling them in correctly.
Form length does not directly correlate to complexity. Many assume that making forms shorter makes them easier to complete. Though shorter forms might be cheaper to produce initially, if the reduction in content results in user confusion, the cost of resolving completion errors form fillers make as a consequence can significantly outweigh any initial savings. In general forms do need to be as short as possible, but never at the expense of clarity and usability.
