Dear @Foster Maya
This issue typically occurs because Excel relies on your default printer driver to calculate page layouts and PDF rendering. If your default printer doesn't support the specified paper size, or if your printer settings override Excel's setup, the exported PDF defaults to a standard size like Letter or A4.
Here is how you can resolve this issue:
Solution 1: Use "Microsoft Print to PDF" directly
Instead of using the Export menu, print directly to Microsoft's built-in virtual printer to force the correct layout:
- Go to File > Print.
- Under Printer, select Microsoft Print to PDF.
- Under Settings, explicitly select your desired Page Size (e.g., A4, A3, Legal).
- Click Print to save your PDF with the exact dimensions.
Solution 2: Align Page Setup & Default Printer Settings
If you prefer using Export > Create PDF/XPS Document:
- Go to Page Layout tab in Excel > click the small Dialog Launcher arrow at the bottom-right of the Page Setup group.
- In the Page tab, set your Paper size.
- Click Options... at the bottom of that window (this opens your default printer's properties).
- Ensure the paper size in your printer properties matches the paper size set in Excel.
- Click OK on both windows, then try exporting again.
According to Microsoft documentation, Excel retrieves page settings directly from the active printer driver. Changing your active printer or adjusting the driver settings resolves paper size discrepancies upon export.
Please let me know if this solves the issue or if you need further assistance.
