Estimate how many photos or minutes of video fit on your memory card based on file size and card capacity.
Actual file sizes vary based on scene complexity, ISO, and compression. Card capacity uses ~93% of advertised size (formatted capacity). Video bitrates are approximate.
| Resolution | JPEG Fine | RAW | RAW+JPEG |
|---|---|---|---|
| 24 MP | 8-12 MB | 25-35 MB | 35-45 MB |
| 45 MP | 15-20 MB | 45-60 MB | 60-80 MB |
| 61 MP | 20-30 MB | 60-80 MB | 80-110 MB |
Why is my actual capacity different? Memory cards are advertised in decimal gigabytes (1 GB = 1,000,000,000 bytes) but computers use binary (1 GB = 1,073,741,824 bytes). After formatting, you get roughly 93% of the advertised capacity.
Does compression affect file size? Yes, significantly. Lossless compressed RAW files can be 20-40% smaller than uncompressed. JPEG quality settings also affect size.
What about buffer/burst shooting? This calculator shows total capacity. Burst shooting speed depends on your camera's buffer and card write speed, not just capacity.
