# Slide master in PowerPoint: what it is, where to find it and how to edit it > The slide master is the top slide in PowerPoint's Slide Master view. Fonts, colors, background, logo and footer set on it are inherited by the layouts beneath it and by every slide built on them. Open it with View → Slide Master, edit the master first and the layouts second, then close the master view and reapply any changed layout to existing slides. Save the result as a template so new decks start with your design. - Source: https://ai-presentations.com/guides/slide-master/ - Updated: 21 October 2026 - Language: English - German version: https://ai-presentations.com/de/ratgeber/folienmaster/ The **slide master** is the top slide in PowerPoint's Slide Master view, and it decides how every slide in the file looks: fonts, colors, background, logo, footer and the position of each text and picture area. Change it once and every slide built on its layouts follows. Open it with **View → Slide Master**, edit it before you build slides, and save the result as a template. ## What is the slide master in PowerPoint? The master is one level in a short hierarchy. Knowing the four levels explains almost every "why did that not change" problem later. | Level | What it is | What you set there | | ------------ | --------------------------------------------------- | ------------------------------------------------------------------------------------ | | Theme | A set of colors, fonts and effects (Design tab) | Theme colors, heading and body font, effects | | Slide master | The top thumbnail in Slide Master view | Whatever belongs on every slide: logo, background, footer, default text styles | | Layout | One thumbnail below the master, such as Title Slide | The [placeholders](https://ai-presentations.com/glossary/placeholder/) and their positions for one kind of slide | | Slide | The page you edit in Normal view | The actual content | Microsoft's [explanation of the slide master](https://support.microsoft.com/en-US/PowerPoint/training/what-is-a-slide-master-in-powerpoint) says a theme is a set of colors, fonts and effects and that every theme includes a master and layouts. Its page on [templates and themes](https://support.microsoft.com/en-us/PowerPoint/understand-the-difference-between-powerpoint-templates-and-themes) adds that a template is a theme plus sample content. A [slide layout](https://ai-presentations.com/glossary/slide-layout/) holds the formatting, position and placeholder boxes for one type of slide, and it inherits from the master above it. ## Where do I find the slide master? **Steps** 1. Open the **View** tab. In the **Master Views** group, choose **Slide Master**. On a Mac, use **View → Slide Master**. 2. Look at the thumbnail pane on the left. The master is the top thumbnail; the layouts are indented below it. 3. Select the master or a layout and edit it. The **Slide Master** tab on the ribbon holds the tools for this view. 4. Choose **Close Master View** on the Slide Master tab when you are done. On a Mac the button is called **Close Master**. PowerPoint for the web has no slide master. Microsoft's support page [Where's the slide master?](https://support.microsoft.com/en-us/powerpoint/where-s-the-slide-master) says to choose **Editing → Open in Desktop App** near the upper right corner and open **View → Slide Master** there. ## How do I edit the slide master? Work from the top down: master first, layouts second. Microsoft advises editing masters before you create slides, because a layout you change later has to be reapplied to the slides that use it. **Steps** 1. Set the slide size first. **Design → Slide Size** offers Standard (4:3), Widescreen (16:9) and Custom Slide Size. Widescreen is the default for new presentations, and all slides in a file share one size. The [aspect ratio](https://ai-presentations.com/glossary/aspect-ratio/) entry explains the choice. 2. Open **View → Slide Master** and select the top thumbnail. 3. Set the theme fonts: on the **Slide Master** tab choose **Fonts → Customize Fonts**, pick a heading font and a body font, name the set and save it. 4. Set the theme colors: **Colors → Customize Colors** opens the Create New Theme Colors dialog. Choose the colors, name the set and save it. Backgrounds come from **Background Styles** on the same tab. 5. Format the title and body placeholders on the master. Their font, size and color become the defaults for the layouts below. 6. Add the logo. Microsoft's own steps: select the master, draw a shape about the size of the logo with **Insert → Shapes**, right-click it, choose **Format Shape**, pick **Picture or texture fill**, insert the logo file and remove the outline. Microsoft also says a picture that should appear on every slide of a type belongs on the master, so **Insert → Pictures** works too. 7. Switch on footers: on the Slide Master tab, in the **Master Layout** group, tick **Footers** on the master and on each layout that needs one. 8. Choose **Close Master View**. The logo page carries a warning worth remembering: according to Microsoft, all slides except title slides show a logo added this way. If the logo belongs on the title slide too, add it to the Title Slide layout. ## How do I add or change a layout? Layouts are the choices people see under **Home → Layout**. Build the ones your team needs and delete the rest. **Steps** 1. In Slide Master view, select the layout closest to what you need, or choose **Insert Layout** on the Slide Master tab to start a new one. 2. Choose **Insert Placeholder**, pick a type, then drag on the layout to draw it. Drag a corner to resize it and an edge to move it. To delete a placeholder, select its border and press Delete. 3. Name the layout: right-click it, choose **Rename Layout**, type a clear name and confirm with **Rename**. 4. Close the master view, select the affected slides in Normal view and reapply the layout with **Home → Layout**. Here is what placeholders organize. On a typical content slide such as this example, the title sits at the top and the chart or text fills the area below. In a file built on a master, both positions come from one layout, so every slide of that kind lines up. *A content slide: title on top, content area below.* 4. Revenue grew in every region; the Nordics led with +27% > **Warning: Placeholders belong to layouts** > > Microsoft's page on [adding or editing placeholders](https://support.microsoft.com/en-us/office/add-edit-or-remove-a-placeholder-on-a-slide-layout) says placeholders can only be added to layouts, not to individual slides. It also advises against deleting placeholders from the built-in layouts: duplicate the layout, give the copy a unique name and edit the copy. Real placeholders also keep your deck easier to read and to reuse. A title typed into the title placeholder shows up in **View → Outline View**, and tools that work from placeholders, such as Microsoft Copilot, depend on them (see [how Copilot uses a company template](https://ai-presentations.com/guides/copilot-powerpoint-company-template/)). ## Why are my slide master changes not showing? Most problems come from one of six causes. Find your symptom in the table. | What you see | Why | Fix | | ------------------------------------------- | ------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Existing slides ignore a changed layout | A layout change does not reach slides that already use it | In Normal view select the slides, choose **Home → Layout** and pick the layout again, or use **Home → Reset**, which keeps the content you added | | Footer or slide number missing | Footers is off on the master or layout, or not switched on for the slides | Tick **Footers** in the Master Layout group on the master and each layout, then use **Insert → Header and Footer** | | Text keeps its old font | Formatting applied by hand overrides the theme | Select the text, open the font list on the Home tab and choose the theme heading or body font at the top; to swap one font for another everywhere use **Home → Replace → Replace Fonts** | | A font change reaches only part of the deck | The file has more than one master | Change the font on each master | | Pasted slides bring their old look | Keep Source Formatting keeps the original theme | Paste with **Use Destination Theme** via the Paste Options | | No Slide Master view in the browser | PowerPoint for the web has none | **Editing → Open in Desktop App** | All of these fixes come from Microsoft's support pages on [editing and re-applying a layout](https://support.microsoft.com/en-US/PowerPoint/edit-and-re-apply-a-slide-layout) and on [changing fonts](https://support.microsoft.com/en-us/powerpoint/change-the-fonts-in-a-presentation). If you want to put a different design on a finished deck, read [how to apply a template to an existing presentation](https://ai-presentations.com/guides/apply-template-to-existing-presentation/). ## Can a presentation have more than one slide master? Yes. In Slide Master view, choose **Insert Slide Master** on the Slide Master tab. The new master appears below the existing ones with no theme colors or effects. Give it a theme through the Background group, or through **Themes** in the Edit Theme group. Use a second master only when one file really needs two designs, for example your own design and a co-branded partner design. Every extra master is another place where a font or footer has to be changed. Microsoft notes that Microsoft 365 subscribers on Windows get a message about unused masters once a file holds 25 or more. ## How do I save my slide master as a template? **Steps** 1. Check the master: fonts, colors, logo, footers and a tidy set of layouts. Add any sample slides you want people to start from. 2. Choose **File → Save As** (or **Save a Copy**) and set the file type to **PowerPoint Template**. PowerPoint switches the location to Custom Office Templates. 3. Start new decks with **File → New → Personal** and double-click your template. On a Mac, use **File → Save as Template** to save it. To keep only the design, choose **Themes → Save Current Theme** on the Slide Master tab. PowerPoint stores a .thmx theme that then appears under Custom in the theme gallery. PowerPoint for the web cannot create templates; the steps are on Microsoft's page [Create and save a PowerPoint template](https://support.microsoft.com/en-us/PowerPoint/create-and-save-a-powerpoint-template). What belongs in a company template, and who should maintain it, is covered in [building a corporate design template](https://ai-presentations.com/guides/corporate-design-powerpoint-template/). For font choices, see [the best fonts for presentations](https://ai-presentations.com/guides/best-fonts-for-presentations/). ## Can an AI work with my slide master? The AI reads theme fonts and colors, each slide's layout, repeating footers and speaker notes from a .pptx you open, and builds new slides in the same design. To change a font or color on every page at once, ask the AI. How this works with your own design is described on the [company template page](https://ai-presentations.com/ai-presentation-company-template/). **Prompt: Add slides in the design of your own deck** ```text Open my attached PowerPoint file and keep its design: fonts, colors, logo and footer. Add five slides after slide 6 about [topic], each with an action title and the figures from the attached Excel file. Do not change any existing slide. At the end, list the new slides and the layout each one uses. ``` The AI builds the new slides in the design it read from your file. Treat the result as a first version: compare it with your own slides, and check every figure and name before you send the deck. **Key takeaways** - The slide master is the top slide in Slide Master view; layouts and slides inherit from it. - Open it with View → Slide Master, edit the master first and the layouts second, then reapply changed layouts in Normal view. - Most "my change is not showing" problems come from a layout that was not reapplied, formatting done by hand or footers that are switched off. - Save the master as a template (File → Save As → PowerPoint Template) so every new deck starts with your design. ## Frequently asked questions ### Where is the slide master in PowerPoint? On the View tab, in the Master Views group, choose Slide Master. On a Mac, use View, then Slide Master. The master is the top thumbnail in the left pane and the layouts sit below it. PowerPoint for the web has no slide master: Microsoft's support page tells you to choose Editing, then Open in Desktop App, and open the master there. ### How do I edit the slide master? Open View, Slide Master, select the top thumbnail and change fonts, colors, background, logo and text styles there. Layouts beneath it inherit the change. Then choose Close Master View on the Slide Master tab. If you changed a layout itself, for example moved a placeholder, reapply it to existing slides with Home, Layout. ### Why are my slide master changes not showing on my slides? The usual causes are a changed layout that has not been reapplied to the slides, text formatted by hand that overrides the theme, a footer that is switched off on the master or layout, or a file with more than one master. Reapply the layout with Home, Layout, restore theme fonts from the font list, and tick Footers in the Master Layout group. ### Can a PowerPoint presentation have more than one slide master? Yes. In Slide Master view choose Insert Slide Master on the Slide Master tab. The new master has no theme colors or effects until you assign a theme. Use extra masters only when a file needs two genuinely different designs, because a font or footer change then has to be made on every master. ### How do I save my slide master as a template? Choose File, Save As (or Save a Copy), set the file type to PowerPoint Template and save. PowerPoint switches the location to Custom Office Templates, and you start new decks from File, New, Personal. On a Mac use File, Save as Template. PowerPoint for the web cannot create templates. ### Can an AI tool use my PowerPoint slide master? The AI works from the design of your file. It reads theme fonts and colors, each slide's layout, repeating footers and speaker notes from your .pptx and builds new slides in the same design. To change a font or color on every page at once, ask the AI. ## Related pages - [Apply a template to a deck](https://ai-presentations.com/guides/apply-template-to-existing-presentation/): How to put a new PowerPoint template on a finished deck: paste slides with Use Destination Theme or apply a theme, then reapply layouts and fix the leftovers. - [Corporate design template](https://ai-presentations.com/guides/corporate-design-powerpoint-template/): Where to find your company's PowerPoint template and how to build a corporate design template with theme colors, fonts, logo and layouts, then share it. - [Slide layout](https://ai-presentations.com/glossary/slide-layout/): A slide layout is a template for how content is arranged on a slide: which boxes it has and where they sit.
