How to Improve Slide Design for Presentations for Any Audience

I’ve learned that messy slides confuse the audience. That’s why I keep my slide design simple and clear. Here, I share how to improve slide design for presentations in most simplest language, so anyone can create better presentations. So, let me first start with the reasons behind this.

Why Slide Design Matters?

Recently, I experienced that great ideas fail to impress and engage the audience because the slides were overcrowded or confusing. Once attention is lost, it’s hard to regain.

Honestly, good slide design helps me:

Communicate ideas faster

Keep the audience engaged

Look more credible and professional

Support the spoken message

Now, we know the necessity of improved slides. In the next section, let me explain how to do so.

How to Improve Slide Design for Presentations Step by Step

Here is are simple and quick set of instructions which I personally used to enhance the presentation slides, i.e.

#1. Start With One Clear Message Per Slide

One of the biggest mistakes users make that cramming too much information onto a single slide. If you are doing the same, immediately stop doing these practices from now on, and follow a strict rule:

One slide = one idea

If you can’t explain the slide’s purpose in one sentence, redesign it. This crucial step instantly makes slides easier to understand.

#2. Reduce Text and Add Visuals Instead

As per my past experiences, I’ve learned that less text leads to more attention, as slides are not documents. Now, I’m following these rules:

No more than 5–6 lines per slide

No more than 6–8 words per line

Bullet points instead of sentences

If you need to explain something in detail, explain it verbally.

#3. Use Strong Visual Hierarchy

Visual hierarchy tells the audience where to look first. But how to create a hierarchy? Below is the answer:

Use big headings for the main idea

Use small text for details

Leave space to avoid clutter

Keep everything aligned and neat

#4. Choose Easy-to-Read Fonts

Personally, I prioritize readability over style. For the same, I:

Use 1–2 fonts maximum

Sans-serif fonts for better screen readability

Large font sizes, i.e. minimum 24pt for body text

Consistent font usage across all slides

#5. Stick to a Consistent Color Scheme

Color inconsistency is one of the fastest ways to make a presentation look unprofessional. I always choose a limited color palette. To maintain this:

Use only 2–3 main colors

Make the text easy to read on the background

Avoid very bright or clashing colors

Use color only to highlight important parts

Also, make sure slides are readable for color-blind viewers by avoiding red-green combinations.

#6. Use Images Purposefully

Only use visuals that support the message, including:

Simple diagrams

Icons to replace text

Charts instead of tables

Real screenshots for demos

#7. Simplify Charts and Data Visuals

Data-heavy slides are where most presentations break down. So remove from charts:

Unnecessary gridlines

Extra labels

Too many data points

Decorative effects like shadows or 3D

#8. Use Alignment and Grids for a Clean Look

Messy alignment subconsciously distracts the audience. So, always align:

Text blocks

Images

Icons

Headings across slides

#9. Avoid Overusing Animations

Animations can help, but only when used intentionally. Always follow these rules:

Use simple fade or appear effects

Keep the same transition on all slides

Avoid sounds and flashy animations

Use animation only to focus attention

#10. Design Slides to Support Your Story

Before opening PowerPoint or Google Slides, outline your story. For the same:

Start with the problem

Build context

Present the solution

End with a clear takeaway or action

#11. Test Slides From the Audience’s Perspective

Before finalising any presentation, review it as if you were sitting in the audience. To ensure:

Can you understand the slide in 3 seconds?

Is the text easy to read?

Do the visuals help?

Does everything look consistent?
