The top question our photo archivists at ScanMyPhotos get is about what resolution to scan old photos at. Most people ask the same thing before digitizing photos: 300 or 600 DPI? Here’s the simple, straightforward answer with real stories.
300 vs 600 DPI Resolution Explained
You open an old shoebox of prints. Some colors are fading. A child’s grin is softer than you remember. That’s when the question always comes up: Should you scan at 300 DPI or 600 DPI? It’s the most searched question in photo scanning — and for good reason. Resolution decides how crisp, detailed, and future-proof your digital copies will be.
The Quick Answer: 300 vs 600 DPI
- 300 DPI: Great for standard prints, sharing online, and saving space.
- 600 DPI: Perfect for enlargements, restorations, and archiving.
Both give you lasting digital files. The right choice depends on how you plan to use them.
Why Resolution Matters
Think of resolution like watching a movie. 300 DPI is like HD. 600 DPI is 4K. Both look good, but the extra sharpness matters when you zoom in, crop, or reprint. Why scan higher? Future-proof against new screens and tech. Better for cropping or editing. Essential for reprints larger than the original
A Customer Story: Why Jennifer Chose 600 DPI
Jennifer from Denver reached out with this question: “Do I really need 600 DPI, or will 300 be enough for my parents’ anniversary album?” She decided on 600 DPI for about 1000 favorite photos. The result? Stunning detail. The lace on her mother’s wedding dress looked almost three-dimensional. Later, Jennifer’s brother enlarged one scan into a 20×24 canvas print as a surprise gift. It now hangs in their parents’ living room, catching the eye of everyone who visits. Her takeaway? “I never regretted going higher. Those details mean everything.”
The DPI Myth
Many think DPI alone controls digital quality. That’s not true. Pixels matter most. DPI affects how much detail is captured at the scan stage, not the raw digital quality later. For example: A 4×6 scanned at 300 DPI = 1200×1800 pixels (2.1 MP). The same photo at 600 DPI = 2400×3600 pixels (8.6 MP). Those extra pixels give you more room for enlargements without blur.
Everyday Uses for 300 DPI
- Uploading to social media
- Emailing family
- Standard prints like 4×6 or 5×7
- Slideshows and digital frames
- When 600 DPI Is Worth It
- Archiving heirloom photos
- Printing posters or coffee-table books
- Restoring faded or damaged pictures
- Cropping into small details
- Future-Proofing Your Memories
Storage space is no longer an issue. Hard drives and cloud storage are cheap compared to the cost of losing details forever. That’s why many families scan the bulk of their photos at 300 DPI but upgrade their “must-save” images at 600 DPI. As one ScanMyPhotos customer told us: “You can’t go back and rescan once the box is gone.”
