How the numbers work
Photos are counted by dividing your free space by a typical file size for the format you shoot in. HEIF ("High Efficiency" in Settings › Camera › Formats) is the iPhone default and keeps files small. ProRAW files are huge — often 75 MB or more each — because they keep all the sensor data for editing.
Video is where space really goes: a single minute of 4K at 60 fps is about 400 MB, so an hour of it is roughly 24 GB. If you don't need 4K, recording in 1080p at 30 fps uses about 60 MB a minute instead.
