If you want to change the standard paper size in a computer program such as Microsoft Word, Pages or Adobe Acrobat, you can do that very easily by going to the application’s settings. Standard A4 paper size is 8.27 x 11.69 inches, while 8 x 11 inches is the standard paper size in the U.S. Almost all document processing applications support this page size, so converting is not a problem.

Open the page that you want to convert.

Go to “File” from the menu.

Select “Page Setup” or a similar option.

Choose U.S. letter (8 x 11) paper size from the drop-down list. Click “OK” button.

Close the page set-up window.
