How Much Space Do 4K Videos Take on a Phone?

A minute of 4K video typically takes between 170 MB and over 400 MB on a phone, depending on frame rate and codec. At 4K/60fps in H.264 you can exceed 400 MB per minute; the same footage in HEVC often drops to 200-350 MB, and 1080p/30fps runs about 60-130 MB per minute.

How much space does one minute of 4K video use?

4K video (3840x2160 pixels) captures roughly four times the pixel data of 1080p (1920x1080). More pixels per frame means more data to store, even before frame rate is factored in. The table below shows typical per-minute sizes across common phone-camera settings, since the exact number depends on scene complexity (a static tripod shot compresses better than fast motion) and the codec the phone uses to encode it.

Format	Codec	Approx. size per minute
4K/60fps	H.264	400-600 MB
4K/60fps	HEVC (H.265)	200-350 MB
4K/30fps	H.264	250-350 MB
4K/30fps	HEVC (H.265)	170-200 MB
1080p/30fps	H.264	90-130 MB
1080p/30fps	HEVC (H.265)	60-90 MB

These are approximations, not guarantees — a static landscape shot in good light lands at the low end, and fast-motion footage in bright daylight lands at the high end of each range.

Does 4K/60fps use more space than 4K/30fps?

Yes, but not always exactly double. Doubling the frame rate doubles the number of frames the codec has to encode per second, so raw data roughly doubles. In practice, compression finds redundancy between similar consecutive frames, so the size increase from 30fps to 60fps at 4K is often closer to 1.4-1.8x rather than a clean 2x — except in high-motion footage (sports, running water), where it can approach the full 2x because there's less frame-to-frame similarity to compress away.

How much does the codec change 4K video size?

A codec is the compression format used to encode video; it determines how much data is needed to store the same visual quality. HEVC (High Efficiency Video Coding, also called H.265) roughly halves file size compared to H.264 at similar visual quality, which is why most phones now default to HEVC for 4K recording. The trade-off: HEVC files take longer to re-encode, use more processing power, and are less universally compatible with older editing software and some non-Apple devices. For a full breakdown of when each format makes sense, see HEVC vs H.264 file size.

How much storage does a week-long trip of 4K footage need?

A rough way to estimate: multiply your expected minutes of footage per day by the per-minute size for your format, then multiply by trip length. Shooting 10 minutes a day of 4K/30fps HEVC video (roughly 185 MB/minute) for a 7-day trip works out to about 70 minutes total, or roughly 13 GB. Switch that same trip to 4K/60fps in H.264 (roughly 500 MB/minute) and the same 70 minutes balloons to about 35 GB — more than a quarter of a 128 GB phone before a single photo is added. If storage warnings are already showing up mid-trip, why is my phone storage full covers what else is typically competing with video for space.

What can you do before your phone runs out of space?

Start with built-in tools. On iPhone: 1. Open Settings > General > iPhone Storage. 2. Review the recommendations — this screen shows exactly which videos and apps are using the most space and offers to offload unused apps or auto-delete old messages. On Android: open Files by Google and use the Clean tab, which flags large videos and duplicate media directly.

Beyond that, the two real options are deleting footage you no longer need or re-encoding it to a smaller file. Re-encoding (compression) is always lossy — it trades some visual quality for smaller size and never restores the exact original data. Compress videos without losing quality explains how to keep that trade-off as small as possible, and delete or compress old videos walks through choosing between the two per clip.

SnapSweep scans a device's video library entirely on-device (nothing uploads to a server) to surface the largest files and offers HEVC re-encoding for clips worth keeping smaller; review is a manual swipe, and the free tier includes a limited number of deletes and swipes before a paid plan is needed — see current pricing in the app.

What can't a video or photo cleaner do?

No cleaning app — built-in or third-party — recovers space used by the apps themselves, system data, or cached files; those require separate management in Settings > General > iPhone Storage or an app's own storage settings. Video compression is always lossy: HEVC re-encoding reduces file size but also reduces some picture detail, and no tool can shrink a video with zero quality trade-off. Automated scanning can flag likely duplicates or blurry frames, but no algorithm reliably picks the single best frame from a burst or the sharpest take across multiple clips every time — that judgment still needs a human look. Finally, deleting a video from a device and deleting it from iCloud Photos or Google Photos are different actions: if the video is synced, removing it from either the device or the cloud library can propagate that deletion to the linked copy, and the same roughly 30-day Recently Deleted or Trash window applies rather than indefinite separate copies.

FAQ

How much space does one minute of 4K video take on an iPhone?

On an iPhone shooting 4K/30fps in HEVC, expect roughly 170-200 MB per minute; the same footage in H.264 runs closer to 250-350 MB. At 4K/60fps in H.264, a minute can exceed 400 MB. The exact number depends on scene motion and lighting, since compression works better on static, well-lit footage.

Does 4K/60fps use double the storage of 4K/30fps?

Not exactly. Doubling frame rate doubles the raw frames encoded, but compression removes redundancy between similar frames, so file size typically grows by about 1.4-1.8x rather than a full 2x. Fast-motion footage like sports or water compresses less efficiently and can push closer to the full doubling.

What's the difference between HEVC and H.264 for 4K video?

HEVC (H.265) is a newer codec that roughly halves file size compared to H.264 at similar visual quality, which is why most phones default to it for 4K recording. The trade-off is longer re-encode times and less compatibility with older software and some non-Apple devices.

How much storage do I need for a week-long 4K trip?

Shooting about 10 minutes a day of 4K/30fps HEVC footage for 7 days totals roughly 70 minutes, or about 13 GB. The same trip in 4K/60fps H.264 can reach 35 GB or more. Multiply your daily minutes by your format's per-minute size, then by trip length, for a personal estimate.

Does compressing 4K video reduce quality?

Yes. Re-encoding a video to HEVC or a lower bitrate always trades some picture detail for smaller file size — it's lossy, not lossless. The original stays intact until you delete it, so you can compare the compressed and original versions before removing the larger file.

Can I save space by shooting 1080p instead of 4K while traveling?

Yes. 1080p/30fps footage typically runs 60-130 MB per minute versus 170 MB or more for 4K, roughly a quarter to a third of the size. The trade-off is lower resolution for editing, cropping, or future higher-resolution displays, so it's a quality-versus-storage decision, not a free upgrade.
