There is quite a preview size difference. I would recommend to make some tests for a few images with different preview sizes in a session. The previews are in a sub directory of the session. This way you can easily make a calculation by multiplying the preview size times the number of your images to get an idea.

Despite having a high rez monitor , I choose the standard size. The size difference would be too large for tens of thousands of images. I rather wait a moment when I reopen a session or catalog.

Resolution size of Previews does not necessarily increase their sizes.

I did some test before I decided on the preview size. For my Fuji XT2 files, the difference between a preview size of 5120px and 1024px is about 9mb vs 0.48mb per image. It is easy to verify in a session. The files are in a sub directory of the capture directory.

I usually work on my files in a session on my hard drive with limited space, before exporting into a catalog.

There is an excellent video: 'Capture One 7 ways to improve speed and performance' from scott dettweiler. He mentions that the preview size of an image stays the same, even for an cropped image.

BTW One killer tip from this video is, to keep the exposure evaluation window closed, when you don't use it. It drastically improves the performance. I was not aware of that.
