About Memory Card Calculator
MemoryCardCalculator.com has answered one question since 2012: how many photos fit on a memory card? The tool has been cited by photography publications across Europe and used by photographers planning shoots, trips and card purchases.
The 2026 rebuild keeps the same free calculator on the same address, updates the math for modern cameras (high-resolution RAW, HEIC phone photos, 4K video), and adds a dedicated answer page for every common card size.
How the estimates work
We assume usable capacity of ~93% of the advertised size (what's left after formatting), JPEGs of about 0.33 MB per megapixel, RAW files of about 1.1 MB per megapixel, phone HEIC photos of ~3 MB, and video at ~130 MB/min (1080p) or ~375 MB/min (4K). Real file sizes vary with scene detail, compression and camera settings — treat every number as a planning estimate.
