What is the exact size of the paper F4?
F4 is a very commonly used in Southeast Asia paper format, with the United States Legal Size similar, but relatively narrow and short, as with the A4 page size. Its format is 210 mm * 330 mm, but the F4 paper used in Hongkong is 340 millimeters long.
The size of the Legal Size in the United States is: 8.5 "x 14" (about 220 mm x 360 mm).
Because F4 paper is not an international standard, it is different from the Legal Size in the United States. It is difficult for users to use F4 paper when they are long and wide. Otherwise, if the software allows, you can use the custom paper size, otherwise you will use the United States Legal Size, and make adjustments on the border.
