How to Change a PDF Document's Print Size on a Mac

What you need: A Mac with macOS Ventura 13 or later, a saved PDF document, and a printer you have used with this Mac. These steps use Preview.

Before you begin: Turn on the printer and load its paper. If you normally use a printer cable, connect it. These steps change how large the PDF's words and pictures appear on the paper.

1. Click Finder (the blue smiling face) in the Dock, the row of app icons along the edge of the screen.
2. In the menu bar at the top of the screen, click Go, then the folder containing your PDF, such as Documents or Downloads. Open a folder inside it by clicking that folder twice quickly. Continue until you see the PDF you want.
3. Click the PDF once. Click File, move the pointer onto Open With to open its menu, then click Preview.
4. In Preview, click File, then Print.
5. Choose your printer from the Printer menu. Set Paper Size to match the paper loaded in the printer.
6. Scroll through the print settings to the Preview section. Click its heading to expand it if its settings are hidden.
7. Select Scale, then replace the percentage with the size you want. 100% means original size. A higher number makes the contents larger; a lower number makes them smaller.
8. Check the page preview. If any words or pictures are cut off, lower the percentage until the whole page fits.
9. Set Copies to 1, then click Print.

Expected result: The paper copy matches the size shown in the print preview.
