Simple file-volume arithmetic
Estimates item count × images per item × average file size. Decimal storage uses 1 GB = 1,000 MB. It does not include derivatives, metadata, OCR, databases, replicas, backups, filesystem overhead, or preservation copies.
Planning estimate
Use measured file sizes from your own workflow. This is not an archival preservation plan or a vendor capacity guarantee. Inputs are processed locally.
