Current page (not Document) width and height with JSX

Question

Hi,
I am trying to create a script that saves every page of the document and add its width and height to the name.
So far I managed to get the dimensions of the document using:
app.activeDocument.pages.documentPreferences.pageWidth;
app.activeDocument.pages.documentPreferences.pageHeight;
That's ok when all the pages in the document have the same dimensions (Document Preferences).
However, when I use custom pages that does not work.
I tried the code below but does not work either.
for(i=0; i<nb;i++)
     app.activeDocument.pages[i].documentPreferences.pageWidth;
     app.activeDocument.pages[i].documentPreferences.pageHeight;
I have done some research and I don't seem to find any information regarding custom pages dimensions.
Can you please help with this?
Thanks in advance,
Isko

Main();
function Main() {
    var doc = app.activeDocument,
    pages = doc.pages,
    page, width, height;
    for (var i = 0; i < pages.length; i++) {
        page = pages[i];
        width = page.bounds[3] - page.bounds[1];
        height = page.bounds[2] - page.bounds[0];
        $.writeln("Page: " + page.name + " - " + "width = " + width + ", height = " + height);
