Making a 1-inch ID photo at home starts with getting the standard right: 25 × 35 mm at 300 dpi. This guide runs from those settings through swapping the background and cropping, then tiles the copies onto 5-inch paper for printing. Change the background in Online PS and skip another trip to the photo studio.
1. What you need
- Original photo: facing the camera, features straight, no exaggerated expression (a phone or digital camera is fine)
- Photoshop (or Online PS)
- Solid-colour background (white, light blue, red and so on — optional)

| Background colour | White / light blue / red |
| Head proportions | 8–10 mm from the top of the head to the top edge; the head fills about 2/3 of the photo height |
