resizing photo to be scanned

[tttt4]

I just installed SilverFast 8 for my Epson V600 scanner and am attempting my first scan with this app.
It's not apparent to me in the navigating the presets for scanning for setting a size I want the photo scanned to. Some guidance would be appreciated.

Dear customer,

you can set the resolution (and therefor the size of the scan) in the scan dimensions window.

Kind regards,
