Are you wondering how many photos a 64GB SD card can hold for your camera? This comprehensive guide from dfphoto.net will break down everything you need to know about SD card capacity, image file types, and how to maximize your storage for photography and visual arts. We’ll cover all the details, so you can capture every moment without worrying about running out of space.
1. What Impacts How Many Photos Fit on a 64GB SD Card?
The number of photos a 64GB SD card can hold hinges on several factors, predominantly the image file type (JPEG or RAW), the camera’s megapixel count, and desired image quality.
Image File Type:
- JPEG: This compressed format takes up less space but sacrifices some image data.
- RAW: This uncompressed format retains all image data, providing more flexibility in post-processing but requiring significantly more storage.
Camera Megapixels:
- Higher megapixel counts result in larger image files, reducing the number of photos that can be stored.
- Lower megapixel counts result in smaller image files, increasing the number of photos that can be stored.
Image Quality:
- Higher quality settings (less compression) result in larger files and fewer photos.
- Lower quality settings (more compression) result in smaller files and more photos.
2. How Many Photos Can a 64GB SD Card Hold? JPEG vs. RAW
To give you a clearer idea, let’s break down the approximate number of photos a 64GB SD card can hold for both JPEG and RAW formats:
| Image File Type | Average File Size | Approximate Number of Photos on 64GB SD Card |
|---|---|---|
| JPEG | 5MB | ~12,800 photos |
| JPEG | 7MB | ~9,142 photos |
| JPEG | 10MB | ~6,400 photos |
| RAW | 20MB | ~3,200 photos |
| RAW | 30MB | ~2,133 photos |
| RAW | 40MB | ~1,600 photos |
This table demonstrates the significant difference in storage capacity between JPEG and RAW files. If you shoot primarily in JPEG, you’ll be able to store many more images compared to shooting in RAW.

3. What is the Difference Between JPEG and RAW Files?
Understanding the differences between JPEG and RAW file formats is crucial for making informed decisions about your photography workflow.
3.1. JPEG Image Files
JPEG (Joint Photographic Experts Group) is a widely used image format known for its compression capabilities. When a photo is saved as a JPEG, the camera processes and compresses the image, discarding what it deems unnecessary data.
Advantages of JPEG:
- Smaller File Size: JPEGs take up less storage space, allowing you to store more photos on your SD card.
- Compatibility: JPEGs are universally compatible with virtually all devices and software.
- Convenience: JPEGs are ready to share and print without any post-processing.
Disadvantages of JPEG:
- Lossy Compression: The compression process reduces image quality, which can be noticeable with heavy editing or multiple saves.
- Limited Editing Flexibility: JPEGs offer less flexibility for extensive post-processing adjustments.
3.2. RAW Image Files
RAW files contain all the unprocessed data captured by your camera’s sensor. This format provides the highest level of image quality and flexibility for post-processing.
Advantages of RAW:
- Maximum Image Quality: RAW files retain all the original data, resulting in superior image quality and detail.
- Extensive Editing Flexibility: RAW files allow for significant adjustments to exposure, white balance, and other parameters without quality loss.
- Non-Destructive Editing: Changes made to RAW files are stored as metadata, preserving the original file.
Disadvantages of RAW:
- Larger File Size: RAW files require significantly more storage space compared to JPEGs.
- Post-Processing Required: RAW files need to be processed and converted into a viewable format (e.g., JPEG) before sharing or printing.
- Software Compatibility: RAW files may require specialized software for viewing and editing.
4. How to Calculate the Number of Photos a 64GB SD Card Can Hold
To calculate the approximate number of photos a 64GB SD card can hold, use the following formula:
Capacity of SD Card (in MB) / Average File Size (in MB) = Number of Photos
Example:
- A 64GB SD card has approximately 64,000 MB of usable storage (since 1 GB is roughly 1000 MB).
- If your JPEG files are around 7MB each:
- 64,000 MB / 7 MB = Approximately 9,142 photos
This is just an estimate, but it can help you plan your storage needs.
5. How Megapixels Affect Photo Storage on Your SD Card
Megapixels (MP) refer to the number of pixels that make up an image. A higher megapixel count means the image contains more detail, resulting in a larger file size. Here’s how megapixels impact storage:
| Camera Resolution | Average JPEG File Size | Average RAW File Size |
|---|---|---|
| 12MP | 3MB – 5MB | 15MB – 20MB |
| 24MP | 5MB – 8MB | 25MB – 35MB |
| 36MP | 7MB – 10MB | 35MB – 45MB |
| 48MP | 9MB – 12MB | 45MB – 60MB |
As the megapixel count increases, the file size grows, reducing the number of photos you can store on your 64GB SD card.
6. SD Card Types: Which One is Right for You?
Choosing the right SD card is essential for optimal performance. Here are the common types of SD cards:
| SD Card Type | Capacity Range | Description |
|---|---|---|
| SD (Secure Digital) | Up to 2GB | The original SD card format, now largely outdated. |
| SDHC (Secure Digital High Capacity) | 2GB – 32GB | An improved version of SD, offering higher capacities. |
| SDXC (Secure Digital eXtended Capacity) | 32GB – 2TB | Designed for high-resolution photos and videos. |
| SDUC (Secure Digital Ultra Capacity) | 2TB – 128TB | The latest standard, supporting extremely high capacities. |
For most modern cameras, SDXC cards are the best choice due to their higher capacity and faster read/write speeds.
7. Speed Class and UHS Ratings Explained
SD card speed is crucial for capturing high-resolution photos and videos without lag. Here’s what you need to know about speed classes and UHS ratings:
- Speed Class: Indicates the minimum write speed in MB/s. Common speed classes include Class 2, Class 4, Class 6, and Class 10.
- UHS (Ultra High Speed): UHS cards offer faster read/write speeds. UHS-I cards have a maximum speed of 104 MB/s, while UHS-II cards can reach up to 312 MB/s.
- Video Speed Class: Designed for video recording, V30 cards guarantee a minimum write speed of 30 MB/s, while V60 and V90 cards offer even faster speeds.
For 4K video recording and burst photography, a UHS-II card with a V30 or higher video speed class is recommended.
8. How to Choose the Right SD Card for Your Needs
Consider these factors when selecting an SD card:
- Camera Compatibility: Check your camera’s manual for supported SD card types and speed classes.
- Storage Capacity: Determine how much storage you need based on your shooting habits and file types.
- Speed: Choose a card with a speed class and UHS rating that matches your camera’s capabilities and shooting requirements.
- Brand Reputation: Opt for reputable brands like SanDisk, Sony, and Lexar for reliability and performance.
