Reduce page size proportionally

Explorer ,
Oct 21, 2019 Oct 21, 2019

I have two PDFS that I am combining. One is 5.5 x 8.5 inches and the other is 11.69 x 16.54 inches. The second PDF contains engineering drawings, and I don't want to crop it or remove any content, but I do want to reduce the page size to 5.5 x 8.5 while keeping the drawings proportional. Is this possible in Acrobat? I have Adobe Acrobat Pro 2017.

Hi Lara_M_T,

 

As you need to reduce the page size, you may try the Print to Adobe PDF  option and can add the custom size for the page.

Use the steps provided below:

- Open the PDF in Acrobat

- Click on the print icon.

- In the print window, select "Adobe PDF" as the Printer.

- Then, go to Properties >  Adobe PDF settings > Adobe PDF page size and click on Add button.

- Now add the Paper name and set the width & height as required.

- Presss the Add/Modify button.

- Now, for Adobe PDF page size, select the added custom page size from the crop down list.

- After that, click on the OK button and then click on the Print button.

Check the screenshot provided below:

Let us know hwo it goes.

 

Regards,

Meenakshi

Thank you Meenakshi.

When I tried to adjust the page size, I didn't see a Custom option in the Adobe PDF Page Size dropdown. I tried to modify an existing page size and got this error message:

Do you know if one of the options in the list is equal to the half page (5.5 x 8.5 in.) size?

Had that same problem but could solve that by selecting the paper size using the dropdown buttom and the options on the previous window. Do NOT open the "add" window. Instead. Just select the paper *type and press  *OK. I used  -Letter Size- to set all my pages to that same default office paper size and it worked (no pages bigger than others). And saved as a new/updated file.
