The key principles of Pitch Deck presentation include:   - One slide represents one thought. Make it clear for the audience and easier for the speaker by expressing thoughts without switching from one thought to another.    - Recommended font size at least 30 pt. Larger fonts are recommended for better delivery of the project to the audience. It also ensures readability and, therefore, recognition and interest in your project.   - The overall presentation size of around 15 slides is optimal for perception and considered the best practice. Not having enough slides may result in the pitch deck looking incomplete and raise many questions, meanwhile making too many slides overload the presentation. Use a reasonable amount of slides that show research and logically present the idea.
