How to Print Photos at Exact Physical Size on Any Printer
When printing photos at home or in the office, ordinary photo viewers often resize pictures automatically to fill the page, altering their intended physical proportions. Our Print Photo Size & Layout Tool creates an exact mathematical PDF where every photograph preserves its physical dimensions (10×15 cm, 13×18 cm, 5×5 cm, or custom millimeters) without unwanted downscaling or pixel degradation.
Step-by-Step Guide
- Upload your photos: Drag and drop one or multiple JPG, PNG, or WebP images into the drop area.
- Set physical dimensions: Choose a popular preset (10x15, 13x18, 5x5 cm) or type custom width and height in centimeters, millimeters, or inches.
- Configure paper and copies: Select paper size (A4, Letter, A3) and set desired copies per image. Use "Auto-fill" to maximize copies per sheet.
- Export and Print: Click "Export Print PDF" and print with your viewer set strictly to "100% Scale / Actual Size".
Image Quality & Honest DPI Evaluation
Utilizamos la imagen original siempre que el formato lo permite y evitamos recomprimirla innecesariamente. The effective print resolution (DPI) is calculated directly from your source pixels relative to requested physical print dimensions without artificial resampling:
- ≥ 300 DPI: Very good. Optimal sharpness for photo albums, framing, and close inspection.
- 200–299 DPI: Good. Ideal for school projects, family prints, and standard photo paper.
- 150–199 DPI: Acceptable. Perfectly legible at standard viewing distance.
- < 150 DPI: Low. Photo resolution is small for this physical size; it may look soft or pixelated.
