Factors Affecting Photo Storage
Several factors determine how many photos fit on a memory card or hard drive:
- Resolution: Higher resolution images (measured in megapixels) consume more storage. A 24MP image will take up more space than a 12MP image.
- File Format: Compressed formats like JPEG require less storage than uncompressed RAW formats favored by professionals for their higher quality and editing flexibility.
- Compression Settings: Higher JPEG compression reduces file size but can compromise image quality. Lower compression preserves quality but uses more space.
Photos Per Memory Card Size: A Breakdown
Let’s examine storage capacity across different memory card sizes, considering both JPEG and RAW formats. We’ll assume an average JPEG file size of 4MB and a RAW file size of 30MB. These are estimates, and actual file sizes can vary.

Additional Tips
-
Card Speed: Fast read/write speeds (UHS-II, V60/V90) are crucial for RAW and 4K video.
-
Regular Backups: Safeguard your photos by backing them up frequently to prevent data loss.
-
Avoid Overfilling: Don’t max out your card. Leave some free space to prevent potential errors.
