CAPS slow you down. And trip you up.

Designers love using them. They look clean, modern and powerful. And fair enough. In a logo or a poster, they can work. But in a presentation? Not a good idea.
You might think, “If I write everything in capitals, it will stand out more.” But in reality the opposite happens. You make it harder to read.

Research shows: we read up to 20% slower in all caps.
Why? Because we don’t read letter by letter. We recognize shapes. And that’s the problem, all caps have the same shape. No tails. No ears. Just blocks. Pretty, maybe. But not for slides. Lowercase simply reads faster.

If your audience has to decode what's on your slide, you've already lost them.
Slides full of capital letters are distracting. People struggle to read and while they're trying, they miss what you're saying.
A waste of your presentation. A waste of your impact.

Watch your tone.
ALL CAPS COME ACROSS AS ANGRY.
As if you’re shouting. Especially also in digital spaces (socials, emails, comments).
Not ideal if you want to sound clear, respectful, and professional.

When can you use them?
Sometimes. Very rarely.
Only for ultra-short statements, commands, one or two words at most

• STOP!
• DO IT!
• START
• NO!

Just remember. It only works because you rarely use it
If everything shouts, no one hears a thing

Bottom line:
Capital letters are tiring. Use them sparingly. Or better yet, avoid them
Lowercase creates calm. Clearer to read. Easier to grasp.

Give your audience space to listen. Not puzzles to figure out on your slides
