Media File Size Reference Table

Media Type Average Size (MB) Items per GB
Standard Photo (JPEG, 12MP) ~ 4 MB 250 photos
High-Res Photo (RAW, 24MP) ~ 30 MB 33 photos
1 Minute of HD Video (1080p, 30fps) ~ 130 MB 7.5 mins

Why the Variation?

The size of a photo or video isn't static. It relies entirely on compression and resolution. A photo taken with a lot of light and fine details will result in a larger file size than a photo taken in a dark room. Similarly, a video using the HEVC (H.265) format takes up significantly fewer Megabytes than an older format like H.264.
