Slide Master Changes Seem to Do Nothing
You change a font in the slide master, return to the slides, and nothing changed. Per-slide formatting and layouts that ignore the master override your edits, so the master is working and the slides are simply not listening.
TL;DR / Quick Fix
Quick fix: check which master and layouts your slides actually follow, remove the direct formatting that overrides the master, and reapply the slide layout. When the slides listen to the master again, one change updates every slide at once — test with a single font change first.
Follow these steps
- Check which master your slides use. Open the master view and count the masters. Decks can hold several, and your slides may follow a different master than the one you edited.
- Look for direct formatting on the slides. Select text on a slide and check whether it carries its own font or size. Direct formatting beats the master every time, which is why the master change seemed to do nothing.
- Reapply the layout to stubborn slides. Select the slide and reapply its layout from the layout menu. Reapplying strips the local overrides and hands control back to the master.
- Edit the layout, not just the top master. If a layout has its own font setting, editing the top master will not touch it. Open that specific layout in master view and change it there.
- Check for pasted slides from other decks. Slides pasted from another deck often bring their own master with them. Those slides answer to their original master, not the one you just edited, and they can also change fonts on the new machine.
- Test one change on one slide. Change a single font in the master, then check three different slides. If all three update, the master link is healthy and the earlier edits were blocked by local overrides.
What NOT to do
- Do not edit every slide by hand to match the master. Fix the override once, and the master updates all slides in seconds.
- Do not keep editing the wrong master in a multi-master deck. Confirm which master your slides follow before making changes.
- Do not paste slides from other decks and expect them to obey your master. Pasted slides bring their own formatting until you reapply your layouts.
- Do not assume the master is broken because one slide ignores it. One slide with direct formatting is a slide problem, not a master problem.
Frequently asked questions
Why do master changes not appear on my slides?
Because direct formatting on the slides overrides the master, or the slides follow a different master than the one you edited.
How do I make slides follow the master again?
Remove the direct formatting or reapply the slide layout, which returns control to the master.
Can a deck have more than one master?
Yes. Pasted slides and templates often add extra masters, and each slide follows only its own.
