Follow these 5 rules to make professional presentations

Use meaningful titles:

Life is short: most people won’t read the full content of your slides;

If your slide has a meaning, so should your title.

Make your slides and bullets Mutually Exclusive, Collectively Exhaustive (MECE):

Each title is a distinct point supporting the main goal of your presentation, and all slides together make it irrefutable;

Each Level-1 bullet is a unique argument supporting your slide title, and all Level-1 bullets make this title irrefutable;

Each Level-2 bullet is a piece of evidence supporting the Level-1 bullet, and all Level-2 bullets make this argument irrefutable.

Use clear formatting to highlight the main ideas:

In the best scenario, people will read only your Level-1 bullets: make them count and make them stand with a large font and/or bold;

Your Level-2 bullets are only here to support the main points if needed, so use a smaller font but don’t go anywhere under a Size 10;

Don’t use Level-3 bullets.

Ensure perfect consistency and alignment:

All slide titles should have the same font, color, size and alignment;

All bullets of the same level should have the same font, color, size and alignment.

Use visual anchors to make your slide memorable:

A picture is worth a thousand words;

A chart is worth a thousand numbers;

If you’re out of ideas, use one of these stupid icons just to help anchor your ideas in the reader’s brain.
