Storage Needs Calculator is built for storage space for your files — fast, free, and private. You supply Photos (millions), Video Hours (1080p) and Documents (GB) to Storage Needs; the answer follows at once. The answer from Storage Needs arrives with its working attached. Students and professionals reach for Storage Needs when speed matters. You can disconnect once Storage Needs has loaded; the arithmetic runs locally.

What the defaults give
10 million photos, 20 hours of 1080p video, 5 GB of documents and 200 hours of music total about 135 GB.
That is roughly 0.13 TB, and the tool suggests a 200 GB plan covers it.
How to decide how much storage you need
The estimate adds four file types at fixed averages: 5 GB per million photos, 3 GB per hour of 1080p video, documents in GB as typed, and 0.1 GB per hour of music.
At the default inputs: 10M photos = 50 GB, 20 h of video = 60 GB, 5 GB of documents and 200 h of music = 20 GB. Total 135 GB, which fits a 200 GB plan but not a 100 GB one.
| Photos | Photos alone (GB) | With defaults for the rest |
|---|---|---|
| 1 million | 5 | 90 GB |
| 5 million | 25 | 110 GB |
| 10 million | 50 | 135 GB |
| 20 million | 100 | 185 GB |
Decide in two steps: total the files you already have, then add 20–30% headroom. Drives stay comfortable below about 80% full, and 135 GB × 1.25 = 169 GB, which still lands on a 200 GB plan. Video is the item that moves the total fastest — one extra hour is 3 GB, the same as 600 photos.

How the estimate is built
GB = photos(millions) × 5 + video hours × 3 + documents GB + music hours × 0.1
10 × 5 = 50, 20 × 3 = 60, documents 5, music 200 × 0.1 = 20, total 135 GB.
Where those per-unit figures come from
Five megabytes per photo is a modern phone JPEG at full resolution — HEIC is smaller, RAW is far larger. Three gigabytes per hour is 1080p video, which is roughly 25 Mbps. Documents are counted directly because their size depends entirely on what they are. Music at 0.1 GB an hour is about 220 kbps, a typical streaming-quality download.
Worked examples
10M photos, 20 h video, 5 GB docs, 200 h music → 135 GB
2M photos, 5 h video, 1 GB docs, 50 h music → 28.5 GB
50M photos, 100 h video, 20 GB docs, 500 h music → 570 GB
10M photos in RAW at 25 MB → 250 GB on its own
What pushes storage up fastest
- Video, always. An hour of 4K is 7–15 GB, so ten hours can outweigh a decade of photos.
- Keeping everything. Bursts, duplicates and screenshots are often a third of a photo library.
- Backups and versions. A sync service that keeps deleted files and old versions multiplies the raw total.
- RAW or ProRAW. Five times the size of a JPEG for the same photograph.
Plan for the next two years, not the last ten: phone cameras grow file sizes every generation, and a plan that fits today exactly will not fit next year.
The estimate uses averages — 5 MB a photo, 3 GB an hour of 1080p — and both move a lot. A modern phone photo is closer to 3 MB, while a RAW file is 25 MB or more; 4K video runs about 7 GB an hour against 3 for 1080p. That is why the total is a starting point: 135 GB could be 80 GB or 250 GB with the same habits. Add 20% headroom for the operating system, caches and the way drives fill up.
Frequently Asked Questions
How much storage do 10 million photos need?
About 50 GB at 5 MB a photo. RAW files at 25 MB would need 250 GB for the same count.
Why is video weighted so heavily?
Because it is. An hour of 1080p is about 3 GB, and 4K is two to five times that, so video dominates most libraries.
Is 135 GB a lot?
It fits comfortably in a 200 GB plan but not in a 100 GB one. The next tier up is usually cheaper than two upgrades later.
Does this include the operating system and apps?
No. It counts media and documents only, so add 30–60 GB for a full device backup.
How much space does music take?
About 0.1 GB an hour at 220 kbps. Lossless is three to five times larger, so 200 hours could be 100 GB instead of 20.
Should I buy more than I need?
A tier of headroom is usually enough. Storage tiers are rarely linear in price, so jumping two levels is often poor value.
