Master colour, typography, whitespace, imagery, and animation restraint — 5 design principles that help anyone create professional-looking presentations.

5 PowerPoint Design Principles That Will Transform Your Boring Presentations Have you ever sat through a meeting staring at a slide packed with dense text and clashing colours, struggling to stay focused? A great presentation isn't just about having the right content — it's about keeping your audience engaged from start to finish. These 5 principles will transform anyone's slides. Principle 1: Colour — Less Is More Limit your entire presentation to no more than 3 colours: one primary colour, one accent colour, and one neutral (white, grey, or off-white). Use tools like Coolors.co or Adobe Color to extract colours from your brand logo for visual consistency. Use a light background (white/light grey) with dark text for maximum readability Reserve bright accent colours for highlighting critical information only — never overuse them Avoid using red and green simultaneously (colour-blind friendly design) Keep colour blocks on a single slide to a maximum of 3 colours Principle 2: Typography — Clarity First Your font choices directly affect how professional your presentation feels. Use a maximum of 2 typefaces per presentation: one for headings, one for body text. Recommended Chinese fonts: Source Han Sans, Microsoft JhengHei (clean and modern) Recommended English fonts: Inter, Montserrat, Roboto (all free via Google Fonts) Title font size: 36–44pt; body text: at least 18pt — ensure even the back row can read comfortably Avoid decorative fonts (cursive, artistic scripts) that slow reading speed Set line spacing to 1.3–1.5× so text doesn't feel cramped Principle 3: Whitespace — Let Your Content Breathe Whitespace doesn't mean wasted space — it gives your audience's eyes a place to rest. Information-dense slides prevent focus and retention. Each slide should convey exactly one core message Leave at least 8–10% margin around all slide edges Group related elements together and separate unrelated ones — apply the proximity principle to organise information Keep slide copy under
