The user needs to format or renumber slides consecutively within a PowerPoint custom slide show.

How to Format Slide Numbers in a PowerPoint Custom Show

Product: Microsoft PowerPoint
Device & OS: not provided
Scenario: Presenting a selected subset of slides using the Custom Show feature.
Observed behavior: PowerPoint retains the original slide numbers from the main presentation instead of dynamically renumbering them for the custom show sequence.

Before you start

Keep in mind that PowerPoint intentionally retains original slide numbers in a custom show so that references match the master deck. Achieving consecutive numbering requires using a manual workaround.

Solution 1Recommended

Create a Separate Presentation File

Since PowerPoint cannot automatically renumber slides in a custom show, saving a dedicated copy of your presentation is the most reliable method.

This method involves extracting only the slides you need into a new file, forcing PowerPoint to assign them standard, consecutive slide numbers.

Save a Copy of the File

Click on 'File' > 'Save As' and create a new copy of your PowerPoint presentation to avoid altering the original master deck.

Delete Unnecessary Slides

In the new presentation file, delete all slides that are not meant to be part of your custom presentation.

Apply Slide Numbers

Go to 'Insert' > 'Slide Number' (or 'Header & Footer'), check the 'Slide number' box, and click 'Apply to All'. The remaining slides will now be numbered consecutively.

Best Practice: This approach ensures that handout printouts and PDF exports will also feature the correct, consecutive slide numbers.

Solution 2

Manually Insert Static Slide Numbers

If you must keep all slides in a single file and continue using the Custom Show feature, you can replace dynamic slide numbers with static text.

Frequently Asked Questions

Why do my slide numbers jump out of order during a Custom Show?

By design, PowerPoint retains the original slide numbers from the master presentation in a Custom Show. If your custom show includes slides 1, 4, and 7, they will display those exact numbers rather than dynamically renumbering to 1, 2, and 3.

Can I force a PowerPoint custom show to start at slide number 1?

The Custom Show feature itself does not support dynamic renumbering. To start your presentation at slide 1 with consecutive numbering, you must either manually edit the slide text boxes or save a new copy of the presentation containing only the desired slides.

How do I change the starting slide number for a regular PowerPoint presentation?

To change the starting number of your main presentation, go to the 'Design' tab, select 'Slide Size', and click 'Custom Slide Size'. In the 'Number slides from' field, enter your preferred starting number and click 'OK'.
