You've prepared for months. Syllabus: done. Practice tests: done. You open the CTET registration portal, fill every field carefully — and then the photo upload page.
You try your passport photo. "Invalid Dimensions." You compress it. "File size not in range." You're not alone. CBSE's automated system rejects thousands of valid, eligible candidates every year for photo errors that have nothing to do with their teaching qualification.
This guide fixes it in under 2 minutes.
⚠️ CBSE is Strict!
CTET applications with incorrect photo/signature dimensions are auto-rejected. Unlike other exams, CTET enforces both pixel dimensions AND file size limits.

Why CTET Photo Requirements Are Strict
CTET (conducted by CBSE) uses automated verification:
- Face Recognition Software matches your photo during the exam
- Photos are printed on Admit Card and Exam Hall Attendance
- Poor quality photos cause verification delays at exam centers
- Incorrect dimensions trigger automatic rejection
📸 Common Rejection Reason
Many candidates upload selfies or phone photos without checking dimensions. CTET requires professional passport-size photos with exact centimeter measurements.
