| Element | Best Practice | Quick Evaluation | |---------|---------------|-------------------| | | Consistent grid, generous whitespace, limited to 3‑5 bullet points per slide. | Does each slide feel “balanced” or “crowded”? | | Typography | One primary font (e.g., Helvetica) + one accent; font size ≥ 24 pt for body. | Mixed fonts, tiny text → hard to read. | | Color Scheme | Brand colors used purposefully, high contrast (≥ 4.5:1 for text/background). | Neon backgrounds, low contrast, or clashing colors. | | Imagery | High‑resolution photos, icons, and charts; no pixelated stock images. | Grainy pictures, irrelevant clip‑art. | | Data Visualizations | Simple bar/line charts, clear axis labels, consistent colors for series. | 3‑D pie charts, over‑decorated infographics, missing legends. | | Animation & Transitions | Minimal (fade or none) to keep focus on content. | Flashy animations that distract. |
