It really depends on the length of the presentation, but typically an opening is a brief expression. Perhaps a one to three minutes.

Typically, you should aim to spend about 10-15% of your total presentation time on the opening. For example, if your presentation is 30 minutes long, the opening should be approximately 3-4 minutes. This time should be used to grab your audience's attention, establish your credibility, and set the tone for the rest of your presentation.
