Slide Design Best Practices

Professional design principles for academic presentations

Timing Rule

Aim for 1 slide per 1-2 minutes of speaking. For a 20-minute defense, prepare 10-15 slides maximum. Practice with a timer.

Typography Hierarchy

Use 30-36pt for headings, 24-28pt for body text, 18-20pt for captions. Sans-serif fonts (Arial, Calibri, Helvetica) are most readable.

Color Palette Consistency

Use 2-3 consistent colours: one primary, one accent, one neutral. Ensure high contrast (dark text on light background).

Data Visualizations

Use simple bar/line charts over complex 3D graphics. Label axes clearly. Annotate key findings directly on graphs.

White Space Usage

Leave ample margins. Never fill more than 60% of slide space. One idea per slide prevents cognitive overload.
