Gonna quote the relevant part here but you're welcome to check for yourself  :)

image_size

This file controls the size of hibernation images.

It can be written a string representing a non-negative integer that
will be used as a best-effort upper limit of the image size, in bytes.
The hibernation core will do its best to ensure that the image size
will not exceed that number, but if that turns out to be impossible to
achieve, a hibernation image will still be created and its size will
be as small as possible. In particular, writing ‘0’ to this file
causes the size of hibernation images to be minimum.

Reading from it returns the current image size limit, which is set to
around 2/5 of the available RAM size by default.
