How it works
- Choose a mode: "Find min pixels" to plan a shoot or resize, or "Check my image" to evaluate a photo you already have.
- Enter the desired print width and height in inches, centimeters, or millimeters.
- For "Find min pixels" mode, set the target DPI (300 for professional photo prints, 150 for posters, 72 for banners).
- For "Check my image" mode, enter the pixel dimensions of your existing image.
- Click Calculate to see the minimum pixel requirements or the quality verdict for your image.
- Common print size presets let you jump straight to standard sizes like 4×6, 8×10, or 11×14.
Use cases
- Check whether a phone photo is large enough before ordering a framed print.
- Find the minimum megapixels a camera must capture for a specific poster size.
- Verify a downloaded image will print sharply before including it in a brochure.
- Determine the correct canvas pixel size when designing artwork for a specific print.
- Evaluate scanned photos to see if the scan resolution is sufficient for reprinting.
- Pre-flight check images before sending files to a commercial print lab.
- Compare quality across multiple images to pick the sharpest one for a print job.
