General Best Practices:
Use sans-serif fonts (Calibri, Arial, Helvetica) for accessibility and clarity.

Avoid overcrowding slides—aim for six lines per slide and six words per line as a soft rule.

Maintain high contrast: dark text on a light background or vice versa.

Test your slides on a projector if possible—font sizes often look smaller when projected.
