How to make a PowerPoint deck look professionally done

Quick answer

Professional-looking slides come from restraint, not effects: one idea per slide, a headline that states the point, two fonts at most, strong contrast, generous space, everything aligned to the same edges, real photos instead of clip art, and charts that show one finding. Build on a branded template so every slide matches.

Here is a slide most of us have sat through. A title in one font, six bullet points in another, a stretched logo in the corner, a clip-art handshake, a chart in default colours and a transition that spins. Nothing on it is badly wrong. Together it says “home-made”. The fixes below are what designers do by habit, and none of them need design software beyond PowerPoint itself.

Amateur signs and what to do instead

Step 1: write the story before the slides

Open a blank document, not PowerPoint. Write the headline of each slide as a full sentence that makes a point. Read the headlines in order. If they tell the whole story on their own, the deck will work. If they read like a list of topics (“Background”, “Services”, “Pricing”), the slides will be a list of topics too, and the audience will have to work out the point for themselves.

Step 2: start from a proper template

Consistency is most of what makes a deck look professional, and the easiest way to get it is a template where colours, fonts, logo placement and layouts are already set in the slide master. Use the template’s layouts rather than drawing text boxes on a blank slide, so every heading lands in the same place. If your business does not have defined colours and fonts yet, that is the first thing to fix; our page on brand guidelines explains what they cover.

Step 3: one idea per slide

A slide is a backdrop to what you are saying, not a document. Give each slide one job: one finding, one comparison, one photo of the finished work, one price. If you need more detail, put it in the speaker notes or a handout. Splitting a crowded slide into three simple ones is almost always an improvement, and it costs nothing.

Step 4: set type for the back of the room

• Use your brand’s heading and body fonts and nothing else. Our guide to choosing fonts covers pairings if you are starting from scratch.
• Keep body text large enough to read from the back of the room, and headlines clearly larger. If you are shrinking text to fit, there is too much text.
• Left-align body text. Centred paragraphs are harder to read.
• Avoid all-capitals for anything longer than a few words.

If you also print the deck as a handout, GOV.UK’s guidance on accessible communication formats recommends a minimum 12 point text size for print, and 14 point where the audience includes people with sight loss.

Step 5: make the contrast strong

Pale grey text on white, or brand blue on a slightly different blue, disappears on a projector. Use dark text on a light background or the reverse. The web accessibility standard sets a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text, and the free WebAIM contrast checker tells you whether your colour pair passes. Projectors wash colours out, so aim comfortably above the minimum.

Never put text straight onto a busy photo. Place it on a solid block of colour, or darken the image behind it.

Step 6: align everything and leave space

Turn on PowerPoint’s guides and keep the same margins on every slide. Use the Align tools rather than nudging items by eye, and make gaps between items equal. White space is not wasted space; it is what makes the important thing stand out. A slide that feels slightly empty in the editor usually looks right on a big screen.

Step 7: use better images

• Use your own photos of real work, real premises and real people wherever you can. They are more convincing than any stock image.
• Make photos large. A full-width image with a short headline beats a small photo surrounded by text.
• Use high-resolution files so nothing looks fuzzy on a large screen.
• Place your logo small and in the same spot, using a transparent file so it does not sit in a white box. Our guide to transparent logo files explains which format to use, and how to use your logo covers sizing and spacing.

Step 8: simplify every chart

Decide what the chart should prove, and put that in the headline. Then remove everything that does not help: gridlines, 3D effects, legends you can replace with direct labels, and decimal places nobody needs. Colour most of the bars in a neutral shade and the one that matters in your brand colour. If the audience needs the full table, give it to them afterwards.

Step 9: check accessibility and export

Add alt text to images and charts, give every slide a unique title and make sure reading order makes sense. Microsoft’s guide to making PowerPoint presentations accessible walks through each check, and PowerPoint’s built-in Accessibility Checker flags most problems for you. Our guide to website accessibility covers the same principles for your site.

When sending a deck to someone who will read it rather than watch it, export to PDF so fonts and layout survive on any device, and keep the file size sensible by compressing images.

When the problem is the brand, not the slides

If you follow every step and the deck still looks generic, the missing piece is usually a defined look: a logo that works small, a colour palette with enough contrast and a pair of fonts that suit the business. Those decisions belong in your brand, not in each presentation. Our brand identity design is £299 and covers logo, colours, typography, imagery and guidelines, which then make every deck, proposal and social post easier to get right.
