How Much Storage Does a 4K Video Use?
4K from the iPhone camera and 4K as a word on a website are not the same bill. The camera writes a large original. Instagram and TikTok throw most of that away before anyone downloads it.
Use the camera numbers to plan a recording. Use the file size on the finished download to plan your phone. Do not mix them.
Quick answer. Apple's usual camera estimates are about 60 MB per minute at 1080p 30 fps, about 170 MB per minute at 4K 30 fps, and about 400 MB per minute at 4K 60 fps. Your iPhone shows the figure for its own setting under Settings, Camera, Record Video.
Camera originals, approximately
These are the rounded figures people see for HEVC on iPhone. Your model can differ. Settings, Camera, Record Video is the number that matches the phone in your hand.
About 60 MB per minute at 1080p and 30 fps. About 90 MB at 1080p and 60 fps. About 135 MB at 4K and 24 fps. About 170 MB at 4K and 30 fps. About 400 MB at 4K and 60 fps.
Ten minutes of 4K at 30 fps is roughly 1.7 GB. An hour is roughly 10 GB. 4K at 60 fps is closer to 400 MB a minute, so an hour is roughly 24 GB. ProRes, on phones that offer it, is several times larger again.
How to spend less before you record
For new recordings, set Settings, Camera, Record Video to 1080p at 30 fps if storage is tight. That is the single biggest cut, and it happens before the file exists.
For a download, pick SD when the page lists it. That chooses a smaller file the platform already made. It is not a compressor.
A practical way to estimate space
A rough phone estimate is 350 to 400 MB for one minute of typical 4K. A one-minute 1080p clip is often closer to 100 to 150 MB, and a short 720p reel can be under 20 MB. Your file can be smaller or larger depending on how hard the platform compressed it.
Check the size in Files or Downloads before you save a second copy. Two downloads of the same link double the space. Delete the one you will not watch.
This tool does not offer a 4K file unless the source listed one. Most social clips are 720p or 1080p. Expecting 4K from a Reel will only waste a retry.
Frequently asked questions
Does this downloader save 4K?
Only if the public source actually offers a 4K file. Most social posts do not.
Why is my downloaded video tiny compared with these numbers?
The platform compressed it. The camera table describes an iPhone recording, not a Reel.
Where do I see Apple's estimate?
Settings, Camera, Record Video. The list shows resolution, frame rate, and a storage hint.

A downloaded Reel is not that file
A social app re-encodes the upload. A 30-second Reel is often only a few megabytes, even when someone calls it HD. It is not a 4K camera master, and this site cannot recover the master.
Judge storage from the size your phone reports after the save. On iPhone, that is in Files, next to the filename. On Android, it is in the Download folder details.
