Building a Slide Master in Powerpoint after already creating a presentation

Hello, I'm a designer who's been tasked with creating a slideshow template for a brand. Initially, I was told to simply build out a few slide layouts, referencing their brand guidelines for style. But now, I'm being told that I need to have these slides I've created be accessible via the Slide Master. Can someone explain to me how I should go about building this out?

I understand the general concept of the slide master, but the functionality is only causing me more problems. For example, when I copy and paste the elements from one of my designed slides into the Slide Master, certain elements are editable, and certain aren't. But when I add them as "placeholders", the text can only be bullet points? Also, not all elements on a given Master Slide transfer to the applied slides (see image- the date and header do not show up on my Title Slide layout). I'm so lost, and so very frustrated! Tutorials on youtube make sense to me, but don't seem to apply to my situation. I'd really appreciate some help!!!

PS: If anyone has insight as to why it's important that I do this in master slides, rather than just have the client use the slides I made / duplicate them to their needs, that would be much appreciated. It seems like I'm working backwards, here.

I'm using Microsoft ppt for Mac, version 16.92

It's not letting me upload images directly to this message, so I've uploaded them here. Thanks!

Many designers work with PowerPoint production people who know the technical ins and outs of PowerPoint. The program has very different assumptions from any other design-related Mac app that you use.

Rather than adding slide master/layout content to an existing presentation, it's best to start over with a new deck. This is because your original approach has likely wrecked the inheritance that PowerPoint is built on.

Placeholder text has bullets by default, but you can format the text levels without bullets. Do this on the Slide Master, then create variants on the Slide Layouts.

If you add the date and footer (there is no header on slides) to the slide master, then you must also add then to the layouts that inherit from the master. In a well-constructed file, you can do this by opening View>Slide Master, then unchecking and rechecking the Footers checkbox.

About inheritance:

The mantra for PowerPoint is Theme>Master>Layouts>Slides. This is the order in which PowerPoint inherits formatting.

Start by creating Font and Color Themes. These are the most basic building blocks of any modern Office file. If you're using a Mac, here's my article on how to create a font theme: OOXML Hacking: Font Themes

Step 2 is to apply the font theme to the Slide Master. In Slide Master view, it's the larger thumbnail at the very top of the left-hand thumbnail list. Set the formatting for the slide master to be the formatting for the most commonly-used slide design. Set all the placeholders so the font reads Font Name (Headings) or Font Name (Body).

Next, still in Slide Master view, format each Slide Layout (the smaller thumbnails below the master). For layouts that don't use the slide master formatting, format the background to Hide background graphics, then create a different design.

Finally, create or update the Slides.

The Best Practices category of my blog has many articles that will help you to learn how to format PowerPoint correctly.

    For anyone else who comes across this discussion, John's answer is pure gold.

    If you're creating templates/themes that others will use, you're doing them and yourself a disservice if you don't get a copy of Echo Swinford & Julie Terberg's Building PowerPoint Templates V2

    Hello,

    Welcome to the Microsoft Community Forum. Please accept our warmest regards and sincerest hope that all is well despite the situation you find yourself in.

    I understand your frustration, but I'm here to help you with setting up your Slide Master in PowerPoint for Mac. Here are some steps you can follow to build a Slide Master:

    1. Open your existing presentation in PowerPoint for Mac.
    2. Go to the View tab in the PowerPoint menu.
    3. Click on Slide Master. This will display the Slide Master view.
    4. You can now customize the Slide Master by adding your designed slide layouts, logos, colors, fonts, etc.
    5. To add elements from your designed slides to the Slide Master, you can copy and paste them onto the Slide Master layout you want to modify.
    6. To make elements editable on the slides based on the Slide Master, you can use placeholders. To add a text placeholder, click on Insert Placeholder in the Slide Master tab and choose Text.
    7. Make sure to include all necessary elements on the Slide Master that you want to appear on the applied slides.
    8. Once you have customized your Slide Master, you can close the Slide Master view to return to your presentation.

    Regarding the importance of using Slide Masters:

    • Using Slide Masters ensures consistency across all slides in your presentation.
    • It allows for easy global changes to be applied to all slides at once.
    • It saves time by avoiding the need to manually update each individual slide.

    Hope this helps.

    Best Regards,

    Fordy B.
