Complete Breakdown of 600x600 Pixel Passport Photo Requirements

The 600x600 pixel format is the standard digital dimension for passport and visa photos in the United States and several other countries. This specification applies not only to US passport applications but also to various visas, Green Cards, and student IDs. Understanding these precise requirements is essential for ensuring your application proceeds smoothly.

1. Basic Size Specifications: Digital vs. Print Standards

Passport photo requirements include specifications for both digital and printed versions:

Printed Photo Specifications:

• Dimensions: 2x2 inches (51x51 mm)

• Paper: High-quality photo paper (matte or glossy)

2. Head Size and Position Requirements

Precise control of head size and position is the most critical aspect of passport photo specifications:
