Guide
How many photos fit in 128 GB.
The short answer is: it depends on the format. The same storage can hold very different numbers of photos depending on whether you use HEIC, JPG or RAW.
Quick estimates
| Format | Average size | Approximate photos |
|---|---|---|
| Phone HEIC | 2.2 MB | about 59,000 |
| Phone JPG | 3 MB | about 43,000 |
| Camera JPG | 8 MB | about 16,000 |
| Camera RAW | 28 MB | about 4,600 |
Why there is no single number
Photo weight changes with sensor resolution, format, compression level and whether the image was edited or exported again. That is why pages like this should speak in ranges, not in absolute figures.
How to use this for a purchase
If you take casual photos and not much video, 128 GB may be enough. If you record a lot of video or keep RAW photos, it is smarter to start thinking from 256 GB.
