I get two very different sizes for my ebook in mobi format and, before publishing it, would like to know which size is the one which is taken into account by Amazon for calculating the download fees they charge under the 70% royalties option:
When compiling the file with kindlegen, I get the following sizes:
Approximate Standard Mobi Deliverable file size : 0002805KB Approximate KF8 Deliverable file size : 0002817KB
Now, when I look on my harddisk, I see a mobi file of 11.5MB
Which is the one I'd have to pay for ?
