CN National Computer Rank Examination 144x192 pixels Photo Requirements Guide - Official Guidelines

Requirements

• Photo dimensions: exactly 144 × 192 pixels, with no cropping or padding beyond these limits
• File format: high‐quality JPEG (.jpg) or PNG (.png) with 24-bit color depth, no interlacing
• Background color: plain, uniform light gray or white (RGB 255,255,255) without shadows or patterns
• Head size and position: head (top of hair to chin) must occupy 70–80% of frame height and be centered horizontally
• Face orientation: full-face view, directly facing the camera with both ears visible, no tilt or rotation
• Expression: neutral expression, mouth closed, eyes open and clearly visible without squinting
• Eye level: eyes positioned between 53–60% of the photo’s height from the bottom edge
• Lighting and contrast: even, diffuse lighting on face, no harsh shadows, glare, reflections, or red-eye
• Glasses policy: permitted if normally worn, frames must be thin, lenses clear (no tinted or reflective), eyes fully visible
• Head coverings: only for religious or medical reasons; must not obscure the face or cast shadows
• Attire: everyday clothing in contrast to background (no uniforms, camouflage, or overly bright colors)
• File size limit: between 10 KB and 50 KB, with minimal compression artifacts
• Image clarity: sharp focus, no pixelation, blurriness, noise, retouching, or filters applied
• File naming convention: use “ExamCode_LastName_FirstName.jpg” (e.g., CNRE_Lee_Hua.jpg)

Tips and Best Practices

• Exact Dimensions and Aspect Ratio: always save your photo at exactly 144×192 pixels with a 3:4 ratio to meet upload checks—incorrect sizing is the top reason for automatic rejections, so use an image editor’s “resize” function rather than cropping freehand.
• Optimal Resolution and Clarity: start with a high-resolution capture and then downsize to maintain sharpness—low-res screenshots or repeated compressions create pixelation that the exam system flags as unreadable.
• Plain, Even Background: use a solid white or light-gray backdrop with no patterns or shadows—colored walls or uneven lighting can confuse the facial recognition software and lead to a reject.
• Neutral Expression and Proper Lighting: face the camera directly, keep eyes open, mouth closed and avoid harsh shadows—smiling, glasses glare, or side-lit faces often fail automated ID algorithms.
• Correct Head Position and Proportions: ensure your head occupies about 70–80% of the frame, centered both horizontally and vertically—too much empty space or off-center cropping will trigger a “face not fully visible” error.

Conclusion

In summary, adhering precisely to the CN National Computer Rank Examination 144×192-pixel photo specifications is essential to avoid registration delays or rejections. By following each technical and compositional requirement, candidates ensure their images meet official standards at first submission.
