How big a usb stick need to hold 1200 photos?

The size of the USB stick needed to hold 1200 photos depends on the average file size of each photo. If we assume an average photo size of 3 MB, then 1200 photos would require approximately 3.6 GB of storage. Therefore, a USB stick with at least 4 GB capacity would suffice, but opting for an 8 GB or larger stick would provide additional space for future files or backups.
