A great presentation depends on more than the high-quality information you’re sharing. Here are some essential principles to help you create a memorable slide deck.
 
Choose the right fonts. Use sans serif fonts like Helvetica or Arial for a minimal look and better readability. Stick to two font styles throughout your presentation—one for headings and another for body text—and ensure consistency throughout. Keep the body text at a minimum of 30-point size and titles at 40 points or more.
 
Opt for high-contrast colors. High-contrast color combinations ensure maximum visibility and ease of reading. Limit your color palette to two or three main colors to avoid visual confusion and maintain focus on your key points. 
 
Use pictures effectively. Select images that communicate your message powerfully and succinctly—and use them sparingly. Limit yourself to one meaningful image per slide to maintain clarity and reinforce your message without distracting from the substance.
 
Aim for a clean layout. Avoid clutter by using a simple layout with plenty of white space. Emphasize key points in bulleted lists rather than paragraphs. And use a visual hierarchy to guide the audience’s attention to the most important elements first.
