I believe that is 381 km squared, not 381 square kilometers. Vastly different areas. Germany is much larger than 381 square kilometers.
Oops. You are correct. Thank you. Fixing.
If it’s a square 381km x 381km then that’s 145161km² (and I’m not aware that there’s any difference between “square kilometres” and “kilometres squared”, is there?)
Square x and x squared is the same thing. The proper way to say this is “A square of 381 km width”
Probably should take this post down, since it’s misleading.
3812 k2m2
What is the smallest file size possible for a black PDF of this size? How about one with a solid color pattern, or a standard pattern?
funny, because adobe illustrator shits itself at a couple m²
Some questions…
- How is this measured in sq km, rather than something digital such as pixels?
- Why is it 381? How did they arrive at that number?
- Why is there any limit at all, if it’s this big?
Beginning with PDF 1.6, the size of the default user space unit may be set with the UserUnit entry of the page dictionary. Acrobat 7.0 supports a maximum UserUnit value of 75,000, which gives a maximum page dimension of 15,000,000 inches (14,400 * 75,000 * 1 ⁄ 72). The minimum UserUnit value is 1.0 (the default).
15 million inches happens to be exactly 381 km Source
That’s sooooo arbitrary.
True. But thankfully most of the world uses centimetrs instead of inches nowadays. 😉
To satisfy the anything but metric postulate: 381 km originally are 15 million inches.
However, using some tricks, the size isn’t limited to that.

Remark: The side length of the square correspods to 381 km, subsequently, its area is 145161 km^2 .
381 km^2 are slightly smaller than the city of Cologne.Good to see Germany won’t run out of PDF for their digital mapping efforts and need a costly replacement.
