When I start a new poster project which is to be printed on A4 paper, I select Gimp's A4 dimension
template, but as I recently found out, it is actually NOT A4.
If I import the finished product into MS Word which uses standard A4 sizes, my picture turns out to be longer than expected.
Why is it so? Is it a problem in Gimp or are there different A4 dimensions for text and different for pictures?
