File Storage Estimate

The best way to estimate your file storage needs is to organize all files to be uploaded to TitleLeaf in a single directory. Then, depending on your operating system, determine the size of that directory.

Alternatively, you can roughly estimate your needs (in GB) with the following equation:

x * ( y * 20 MB/ebook + z * 2 MB/title ) * 1 GB / 1000 MB

Where,

x = Number of titles
y = Number of ebooks per title
z = Number of images per title

Assumptions:

Average ebook file size is 20 MB
Average image file size is 2 MB

Example 1: 1 image, 1 ebook per title

Given, 700 titles each with 1 cover image and 1 PDF ebook, the estimated file storage would be 15.4 GB.

700 * ( 1 * 20 MB + 1 * 2 MB ) * 1 GB / 1000 MB = 15.4 GB

Note:

x = 700 titles
y = 1 ebook per title (ie, a PDF)
z = 1 image per title (ie, a cover)

Example 2: 2 images, 2 ebooks per title

Given, 700 titles each with 1 cover image, 1 spread image, 1 PDF ebook, and 1 ePub ebook, the estimated file storage would be 30.8 GB.

700 * ( 2 * 20 MB + 2 * 2 MB ) * 1 GB / 1000 MB = 30.8 GB
