What Fits in X GB?
A gigabyte is an abstract number until you see what it actually holds.
- 32,000
- Photos
- 16,000
- Songs (MP3)
- 85.3 hours
- HD video
- 256,000
- Documents (PDF/Word)
Based on average file sizes — see assumptions below.
“214 GB free” doesn't mean much on its own — is that a lot or a little? This tool translates a storage amount into things you can picture: roughly how many phone photos, MP3 songs, hours of HD video, or documents it could hold, based on typical average file sizes for each.
These are estimates, not guarantees — a RAW photo is much bigger than a compressed JPEG, and a 4K video eats space far faster than 1080p. Use this as a sanity check, not an exact quote.
How to use it
- 01Enter an amount of storage and pick its unit (MB, GB or TB).
- 02Read the estimated count for each file type.
- 03Check the assumptions below the results if you want to see the average sizes used.
Frequently asked questions
How accurate are these estimates?
They're ballpark figures based on typical average sizes — a 12 MP smartphone photo (~4 MB), an MP3 song (~8 MB), an hour of 1080p video (~1.5 GB), and a text-heavy document (~0.5 MB). Your actual files will vary, sometimes significantly.
Why does video take up so much more space than photos?
Video is essentially dozens of images per second, plus audio, so file size scales with both resolution and length. An hour of 4K video can be 4–5× the size of the same hour in 1080p.
Where does this dead weight usually come from?
Mostly duplicate photos synced from multiple devices, burst-mode shots you never cleaned up, and old video exports. Purgify finds exactly these across every cloud account you connect.
