I still haven't found the official size of the ISS pizza box[1] and a search on the WEB doesn't help:

"30 miles deep and 30 miles long around the space station": https://www.vice.com/en_us/article/3dkpyn/international-space-station-dodge-space-junk

"two kilometers above and below the station and 25 kilometers cross-track and down-track": https://arstechnica.com/science/2013/07/how-nasa-steers-the-international-space-station-around-space-junk/

"±25 km in the direction of motion, ±25 km perpendicular to the direction of motion, and ±0.5 km radially from the ISS as it flies in orbit": https://books.google.de/books?id=9mseNE1wkLMC&pg=PA145&lpg=PA145#v=onepage&q&f=false

"0.75 kilometers above and below the station and 25 kilometers on each side": https://www.universetoday.com/92571/iss-will-do-manuever-friday-to-avoid-collision-with-satellite-debris/

Is there any official size?

EDIT

[1]Pizza box: a safety region around the ISS. Please, see the 3rd link page 145 for an authoritative definition, which, in fact, answers my question (from that preview I didn't realize it was published by NASA).

    $\begingroup$ Not sure what you're gonna get more authoritative than the 3rd link, which is an official NASA document. Unfortunately, NASA does not post ISS flight rules. $\endgroup$

  • $\begingroup$ Yeah, I had written an answer based on the same document. I didn't recognize it from the link. So I deleted the answer. The document contains a good overview of the COLA process. $\endgroup$

    $\begingroup$ I suggest adding a definition of the "pizza box" at the top of the question. I would do it by myself but my english skills are not too good. $\endgroup$

I mentioned this in a comment, but an official answer is needed.

The document in your 3rd link is the official-as-it-gets NASA document The International Space Station - Operating an Outpost in the New Frontier

The ISS Flight Rules would be the authoritative source, but NASA does not publish them.

From p.145 in the link.
