What is the Phone Storage Calculator — How Many Photos &?
Pick your phone's total storage (16GB up to 1TB) and roughly how much of it is already used by the operating system and apps (a realistic default is provided, since the OS and pre-installed apps always take a real bite out of the advertised number). Then choose your typical photo quality and video quality, and this tool divides your real remaining free space by realistic reference file sizes to estimate how many photos or how many hours of video actually fit.
Reference sizes are stated plainly since actual file sizes vary by phone model and settings: a typical modern smartphone photo is roughly 3-5MB (higher for RAW or 48MP+ modes), and 4K video runs roughly 350-400MB per minute (1080p is much smaller, at roughly 130-170MB per minute). These are reasonable, commonly-cited reference points, not your phone's exact figures.

What you get
Divides your actual free space by a stated reference file size — transparent, not a guess.
Subtracts a realistic estimate for space the operating system and apps already use.
Switch between photo count and video hours based on your real usage.
Choose standard, high-res or RAW photos, and 1080p or 4K video, to match your real settings.

Questions people ask
Why don't I have the full advertised storage?
The operating system, pre-installed apps and system files use a real, non-trivial amount of the advertised total — commonly several gigabytes on modern phones — which this calculator subtracts before estimating photo/video capacity.
How big is a typical smartphone photo?
Roughly 3-5MB for a standard photo on a modern phone; RAW or very high-megapixel modes (48MP+) can be significantly larger, often 20MB or more.
How much storage does 4K video use?
Roughly 350-400MB per minute is a commonly cited reference for standard 4K/30fps recording; higher frame rates (60fps) or higher bitrates use more, and 1080p uses substantially less.
Does this account for cloud storage?
No, this estimates on-device, full-resolution storage; using a cloud photo service with 'optimize storage' turned on will let a phone hold far more than this calculator's estimate by storing smaller local copies.
Are these exact numbers?
No, they're realistic, commonly-cited reference file sizes — your actual results depend on your specific phone, camera settings and content.
