Create a PowerPoint templates that works
Somebody in your company has a template. It’s got the logo, the right-ish colours, a title slide.
Then old-mate from finance opens it, and the title jumps a yard on slide two. Then page numbers vanish. Fonts change size (and colour!). By Tuesday, the day before the presentation, there are 14 versions and none of them look related.
The fix is a template built by someone who understands how PowerPoint works under the hood. It’s not hard. It just has to happen in the right order.
The order that matters
Canvas (slide size) > Theme colours > Fonts > Master setup > Custom layouts > Default shapes, lines and text boxes > Save as a .potx and check
Skip ahead and you’ll be redoing work. Here’s why...
1. Pick the slide size, then leave it!
Go to Design > Slide Size.
Choose 16:9.
It fills modern screens and gives you more room to work with.
Then don’t touch it again. Change the size after you’ve built layouts and PowerPoint stretches and squashes everything in ways nobody enjoys. Decide once and move on.
Making posters or social graphics?
Use Custom Slide Size. For a presentation template, stick with 16:9 or 4:3.
2. Set the theme colours
PowerPoint gives you 10 colour slots:
• 4 for text and backgrounds
• 6 accents
• 2 for hyperlinks.
Brand colours go in the accents, not the first four. Those first four are reserved for text and backgrounds. Go to Design > Variants > Colors > Customize Colors, then enter your HEX codes.
Two things to know before you choose:
Accent 1 becomes the default SmartArt colour, with white text on top. A pale Accent 1 gives you white-on-pastel. Nobody can read it.
Charts pull colours in accent order: 1, 2, 3, 4. Put colours next to each other that you’d happily see side by side in a chart.
3. Choose the font/s
You get two slots: Headings and Body. They can be the same font or a pair.
We recommend system fonts that come with Windows and Mac. Especially if the template will travel outside of the organisation. A brand font looks great on your laptop. On the client’s computer, it quietly becomes Calibri, and your layout and line endings shifts.
Set them under Design > Variants > Fonts > Customize Fonts. Text then follows the theme fonts, so a font change later is a two-click job instead of an afternoon.
4. Build the slide master first
View > Slide Master. The big slide at the top is the parent. The layouts underneath are its children.
Whatever you do to the parent flows down to every child. So finish the parent before you touch a single layout.
The parent holds five things: title, text, date, footer and slide number. Keep all five, even if you never use them. If someone later turns on the footer and you haven’t formatted it, PowerPoint guesses. The result is a footer that looks different on every deck.
On the parent:
• Size and position the title and body placeholders
• Add anything that should show on every slide, like a logo
• Set the text formatting once, here
5. Add layouts with rules
Layouts are what your team (and AI) actually picks from. A few rules save you grief:
Name every layout clearly. “Half image, half text” beats “Custom Layout 7”.
Duplicate to add one. Select a layout and press Ctrl+D.
Don’t delete PowerPoint’s built-in layouts. When someone pastes a slide in from another deck, PowerPoint tries to match it to the same-named layout. Delete the originals and the match fails, and you get stray extra layouts or broken formatting.
Fence off imported master slides. Put a final layout at the end with a big message like “DO NOT USE ANY SLIDES BEYOND HERE”. Imported layouts all land below this point, so they’re easy to spot and ignore.
Hide background graphics where you need a clean slide, such as a title slide or a full-bleed image. It’s a tick box on the Slide Master tab.
6. Set default shapes and lines
This takes two minutes and prevents hours of tidying later.
On a normal slide, draw a shape, a line and a text box. Format each one the way you want every future one to look. Then right-click each and choose Set as Default Shape / Line / Text Box.
From now on, anything anyone inserts starts on brand, with readable contrast and a sensible font size.
While you’re there, set the text box to Do not Autofit. It looks messier when text overflows, but it’s honest. Autofit quietly shrinks the text or resizes the shape, and you end up with 11 different font sizes in one deck and a design that’s been stretched out of shape.
7. Save it. Then check it
Save as .potx.
Then check two things:
File size. A template should be small, around 2 to 3MB at most. Heavy templates make every deck slow and every deck bigger. If yours is over, delete unused layouts and compress images, or replace them with picture placeholders.
Colour contrast. Test on more than your own screen. A palette that looks crisp on a high-res monitor can turn to mush on a projector.
The takeaway
Even a great template isn’t the end
You can build all of this perfectly and people will still add their own layouts, paste in old slides and invent new shades of blue. That’s normal. Templates reduce chaos. They don’t remove it.
What helps is a template that makes the right thing the easy thing, and a bit of ongoing care when the brand changes or the team grows.
