How It Works

Photos, videos, and documents pile up faster than most people track, and this tool adds them into one total so you can plan storage before you hit a wall. Global data is projected to reach 181 zettabytes by 2026, and the same pressure shows up on a personal scale as cloud plans fill and devices run out of room. Knowing the number ahead of time beats scrambling once the warnings start.

The total comes from multiplying how many items you have by a typical file size for each type. Photos are figured at 5MB apiece, the size of a high-resolution smartphone shot. Video runs about 250MB per minute at 1080p, and documents land near 0.5MB each for an ordinary PDF or Word file.

Treat the result as a working average, since quality and compression push real files well above or below these figures. Your library also grows month over month, so plan for where it will be, not just where it sits today. Adding a buffer of 20-30% gives you headroom for the accumulation you can't predict.

Example: Family's Digital Archive

  1. 1 Input: A family has 10,000 photos, 50 hours of video, and 2,000 documents.
  2. 2 Calculation: Photos: 10,000 * 5MB = 50,000MB (50GB). Videos: 50 hours * 60 minutes/hour * 250MB/minute = 750,000MB (750GB). Documents: 2,000 * 0.5MB = 1,000MB (1GB). Total = 50GB + 750GB + 1GB = 801GB.
  3. 3 Result: Your estimated total storage needed is 801 GB. We recommend a cloud storage plan of at least 1TB to accommodate this data with some room for growth.
  4. 4 Context: For 801GB, popular cloud providers like Google Drive, Dropbox, or Microsoft OneDrive offer 1TB or 2TB plans starting around $9.99 - $19.99 per month. Consider options with family sharing for added value.

Frequently Asked Questions

How much storage do I need for photos and videos?
Photos average 3-5 MB each (12-20 MP) and 4K videos use about 6 GB per hour. A collection of 10,000 photos needs 30-50 GB, and 100 hours of 4K video needs about 600 GB. Plan for at least 1 TB if you take lots of photos and video.
Is cloud storage or an external hard drive better?
Cloud storage provides automatic backup and access from any device but requires a monthly subscription ($3-10/month for 1-2 TB). External drives have a one-time cost ($50-100 for 2 TB) but can fail and offer no remote access. Ideally use both.
How much cloud storage do I get free?
Google Drive offers 15 GB free, iCloud provides 5 GB, Microsoft OneDrive gives 5 GB, and Dropbox offers 2 GB. These free tiers fill up quickly with photos and videos. Paid plans start at $2-3 per month for 100-200 GB.
