Memory Card Calculator
RAW files keep more detail, so they fill a card faster than JPEG files. Enter the card size and the size of each kind of file to compare the shot counts side by side.

How it works
Multiply the card size by one thousand to get megabytes, then divide by the size of one file and round down. Do this once for RAW and once for JPEG.
Real file sizes change with the camera, the scene and the settings, so check a sample shot and enter its size for the most accurate count.
Worked example
A 64 GB card holds about 1,422 RAW shots at 45 MB each, or 5,333 JPEG shots at 12 MB each.
Questions
Why is a RAW file bigger?
A RAW file holds the sensor's data before the camera applies its processing, so it keeps more room for editing. That data takes more space.
Can I shoot both at once?
Many cameras can save both, which uses space for each shot twice. Check your camera's menu for the option.
How do I find a file's size?
Look at the file's details on your computer or phone. The size shown there, converted to megabytes, is the number to enter.
