I'm trying to add a background to an A4-sized Word document.

What is the correct background image size (in terms of resolution) to put into an A4 document? I tried Watermark, Fill effects, and tried to put the image into the header as well.

The image doesn't fit correctly – it will be centered and I need to scale it without causing a quality drop.

Page Layout > Page Color > Fill Effects > Picture > Select Picture.

Use Paint.NET, create image of 210x297mm with 200+dpi resolution and use this image as background. This should work.

Tested with Word 2007.

I have had to this a couple of times for a background you don't want noobs messing with.

795 x 1123 jpg worked for me on A4 in word. When using Fill ->picture function.

Thx, it worked for me. – Kayathiri yesterday

Adjust the picture in "21 : 29.7" ratio by either corping or changing the aspect. Then just insert the picture in the document and selecting "Behind the text" option from "Wrap Text" drop down menu. Lastly, adjust the position and size of that picture...

i think the resolution must be 2480 * 3508
when you make a new image as size A4 in photoshop this is the resolution for it

Thanks for the reply.:). Yeah I tried this one and the same with resolution 100 as well. But the problem is when I insert the pic in word, it comes in center, not stretched.For this any solution? – Midhun Mar 14 '12 at 10:19
@Midhun You never said anything about Word. I edited your question, please check if that's the real problem you have. – slhck Mar 14 '12 at 10:31
How does that link have anything to do with inserting a background into Word? And why would you need CorelDraw? – slhck Mar 14 '12 at 10:45
i don't have any idea to remove margins – hamed Mar 14 '12 at 10:56
@ slhck. thanks..:) Yeah that is the prob I am facing. I think I have mentioned about word. I don't need Coreldraw, dint mention anything about it anywhere. I just want to know what would be the perfect size and perfect way to fit a bg image in word 2007. – Midhun Mar 14 '12 at 11:32

The solution is very simple! Create a4 background image. Open word doc. Go in page setup and set footer, header and all margins values as 0 (zero). Than follow the procedure for insert background image, and image will be calibrated

Save the image you wish to use as A4 size 210 x 297mm at 72DPI (very important) and this will fit perfectly using the Page Background > Colour > Fill Effects method.

Apple uses a default monitor pixel density assumption of 72 DPI. Windows uses 96 DPI (source). This probably won't make a difference for a solid color fill, but might affect sharpness for a background photo. – fixer1234 Oct 6 '15 at 17:23

Word page size A5 Format Fist of all resize your image in width:768px Height:959px resolution 80(dpi) Then Go to Insert tab> click picture > select your resize image > Go to position > click more layout option > select square then select wrapp text left only and click Ok. Go to format tab > Resize your width and height as per your need

What does A5 have to do with the question (which is about A4)? – DavidPostill 2 days ago
