How to zoom in Preview by percentage?

[scissorband]

When I click on Zoom Out once, the words are too small but if I Zoom In once after that, the words are too big. Is there any way I can set a custom zoom percentage?

did you try pinch zoom?

Otherwise, right click the toolbar, select "customize toolbar", and drag in the "scale" text field. That allows you to zoom to (almost) any percentage.
