📦 Storage Size Calculator — worldwide capacity planner
storage size calculator — Estimate real-world digital storage needs across any country.
Whether you archive photos, 4K videos, documents, or music libraries, this advanced tool accounts for
file count, media types, growth rate, safety margin, and redundancy. Built on international standards
(SI decimal & binary units) with interactive pie chart. Adjust sliders & numbers — get instant results
for HDDs, SSDs, cloud backup, or NAS systems.

Global factor reference & standards
🔹 Photo factor (JPEG/HEIC): 12MP ~ 5-8 MB, 24MP RAW ~ 25-40 MB. 🔹 Video factor: 1080p 30fps ~ 150MB/min, H.265 smaller. 🔹 Documents: Word/PDF average 400KB-2MB. 🔹 Music: MP3 320kbps ≈ 2.4MB/min.
🌐 Worldwide & USA note: Average US household generates ~2.3TB/year. This calculator respects both decimal and binary units — choose your preference. Growth & safety margin mirror enterprise best practices.
Suggestion: include redundancy for critical archives (RAID/cloud). The chart shows relative proportion per media type before extra factors.
📘 Frequently Asked Questions
Q: How accurate is this storage size calculator worldwide?
A: It uses configurable media parameters (count × avg size) plus growth, safety, redundancy. You can adjust for any region’s typical file resolution or usage — works universally.
Q: What’s the difference between decimal (GB/TB) and binary (GiB/TiB)?
A: Decimal (1TB=10¹² bytes) used by drive manufacturers; Binary (1TiB=2⁴⁰ bytes) used by Windows/macOS Finder. This calculator supports both to avoid confusion.
Q: Why include growth & safety margin?
A: Data accumulates over time (growth). Safety margin avoids performance issues (SSD/HDD need 10–20% free space). Redundancy protects against drive failure.
Q: Can I use this for cloud/backup planning?
A: Absolutely. Estimate total storage needed for cloud sync, external drives, or NAS deployment — adjust “Other” and redundancy factor accordingly.
