Photo DPI Checker — Complete Guide & Instructions
MakeCard Photo DPI Checker reads an image's pixel dimensions, megapixels, and embedded EXIF DPI, then converts them into real print sizes at any target resolution. Select 72, 150, 300, or 600 DPI and instantly see the print dimensions in inches, centimetres, and millimetres — plus a ready verdict on whether the photo is large enough for passport prints, 4×6 photos, A5, or A4. Photographers and print shops use it to avoid blurry enlargements.
How to Use Photo DPI Checker
- 1 Drop or select a JPG, PNG, or WebP image — it is analysed locally, never uploaded.
- 2 Read the pixel dimensions, megapixels, and any EXIF DPI embedded in the file.
- 3 Choose a target print resolution — 72, 150, 300, or 600 DPI.
- 4 See the print size in inches, cm and mm, and which standard sizes (Passport, 4×6, A5, A4) will print sharply.
Key Features & Capabilities
- Pixel dimensions, megapixel count, and file type/size at a glance.
- Reads embedded EXIF resolution (XResolution/YResolution) when present.
- Print size computed at 72, 150, 300, and 600 DPI in inches, cm, and mm.
- Instant fit check for Passport 35×45 mm, 4×6 photo, A5, and A4 print sizes.
- Everything runs in the browser — photos never leave your device.

Practical Everyday Use Cases
- Confirming a phone photo is sharp enough for a passport-size print.
- Checking whether a downloaded image can fill an A4 page at 300 DPI.
- Verifying DPI requirements before submitting photos to a print lab.
- Deciding the maximum safe enlargement for a framed photo.
Pro Tips for Best Results
- DPI only matters at print time — a 1200×1800 px image prints 4×6 inches perfectly at 300 DPI regardless of any DPI tag in the file.
- For quality prints aim for 300 DPI; 150 DPI is acceptable for large posters viewed from a distance.
- If the passport check fails, use a higher-resolution original rather than upscaling.
Common Problems & Solutions
Many cameras and all screenshots omit the DPI tag — it does not matter, since actual print size is set by pixel dimensions and your chosen DPI.
The file may be an unsupported format — convert HEIC or TIFF images to JPG or PNG first.
Privacy & Security
100% Client-Side Execution
The image is decoded and measured entirely in your browser — it is never uploaded, and nothing is logged or stored.
Frequently Asked Questions
Everything you need to know about using Photo DPI Checker
Select the photo — the tool shows its pixel dimensions and any embedded EXIF DPI, then calculates the exact print size at 72–600 DPI.
For screens yes, but prints need more — use 300 DPI for sharp photos and documents, or 150 DPI minimum for large posters viewed from afar.
Usually yes — a 12 MP image (roughly 4000×3000 px) covers A4 at well over 300 DPI. The fit check in the tool confirms it for your exact image.
Pixels are the actual dots in the file; DPI says how tightly they are packed when printed. Print size = pixels ÷ DPI, which is exactly what this tool calculates.
