They allow you to provide more detailed information than you would put on a slide. They give your audience something to take away from your presentation, to review later. They are one more way for your listeners to be reminded of you and your key messages.

Handouts are especially useful if your presentation is highly technical or complex. They can further explain important information. For example, you may want to include in your handout supporting data that you chose not to include in your presentation, such as contact information, case studies, references, marketing literature, or other collateral materials.

Your handout also can serve as a summary of your key points. In any case, your handout can include more detailed information than you may have had time to cover in your presentation, or which — for your own good reasons — you've chosen not to include in your presentation.
