Pixels have no real meaning for PDF. Why are you asking? – slhck Dec 13 '13 at 6:45
@slhck Do you mean that PDF Pages does not have dimensions? – user281536 Dec 13 '13 at 6:47
They do, but not in pixels. The real question is why you're asking. If you need to create PDFs in a certain format, what stops you from doing so? If that's not the problem, what else is? – slhck Dec 13 '13 at 6:54
@user281536: pdf treats dimensions as vectors and not as discrete pixels. any given "form factor" like A4 or US-Letter just define the aspect ratio a given page should have to look good when the pdf is printed to A4 or US-Letter or whatever. – akira Dec 13 '13 at 6:54
If you allow a user to write text on a PDF, that PDF must already exist or you should already know its dimensions. If you want a standard size choose A4 or letter or whatever is common in the area you live in. – slhck Dec 13 '13 at 6:57

PDF files can contain documents of essentially any size. There is no 'standard'. The most common size in Europe and much of the world is A4 - 210mm x 297mm. In the US it's Letter: 8.5" x 11". Much of PDF content is stored as vectors and will scale, so the size in pixels is dependent of the output device.

Well,what im trying to do is write a text on PDF,I intent to use an Image to show it to the user in real time rather than writing on the PDF itself,so i try to create a bitmap of a common pdf size and write on it – user281536 Dec 13 '13 at 6:54
