If you’re in the United States or Canada, standard printer paper dimensions for most documents is that of the standard letter paper size, which is 8.5 inches by 11 inches. In much of the rest of the world, it is A4, which is 297 millimeters by 210 millimeters.
Thereof, can I print A4 on letter?
When printing a letter size design onto A4 you also need to choose the fit button in your printer menu. A4 paper is not as wide as US letter but it’s longer so a bit of extra white space is added to the top and bottom (refer to the preview in the image below).
Regarding this, is A4 the same as legal?
Legal size paper is 8.5 x 14.0 inches (216 x 356 mm), whereas A4 size paper is 8.3 x 11.7 inches (210 x 297 mm). Legal and A4 size paper have little in common with each other, as legal paper is still taller than A4, which is much more closely related to letter size paper.
