Framed prints are a beautiful way to display photos — but printing small digital images on large paper results in blurry, pixelated prints that look nothing like the crisp photos on your screen. Here is how to enlarge photos for framing while preserving maximum quality.
Print Size vs Required Pixels
| Frame Size | Pixels at 300 DPI | Pixels at 150 DPI |
|---|---|---|
| 4×6 inch | 1200×1800 px | 600×900 px |
| 8×10 inch | 2400×3000 px | 1200×1500 px |
| A4 (8.27×11.7 in) | 2480×3508 px | 1240×1754 px |
| 16×20 inch | 4800×6000 px | 2400×3000 px |
| 20×30 inch (canvas) | 6000×9000 px | 3000×4500 px |
How to Enlarge for Framing Free
Upload your photo to imgresizr.com and use the Enlarge tool. Enter the required pixel dimensions from the table above for your desired frame size.

Getting the Best Print Quality
- Always print at 300 DPI for photos — 150 DPI is acceptable for large canvas prints viewed from a distance
- Use a professional photo lab for best results — they calibrate colour and use quality paper
- Calibrate your monitor if you want colours to match the print accurately
- Order a proof (test print) before ordering large canvas prints
