Board Exam Photo & Signature Guidelines (2025)
Class 10th and 12th students! Don't let a technical error in your registration form delay your hall ticket. Learn the exact rules for CBSE, ICSE, and NIOS.
The board exam registration process is a crucial milestone for every student. Whether you are in CBSE, ICSE, NIOS, or a State Board, the digital photograph you upload today will appear on your marksheet and hall ticket for years to come.
Board servers are often overloaded during the registration window, and an oversized image is the number one reason for "Server Timeout" errors. Here is how to format your files correctly.
1. CBSE Class 10 & 12 Requirements
The Central Board of Secondary Education (CBSE) requires a color photograph taken against a light-colored background.
CBSE Photo Specs
- Dimension: 3.5 cm x 4.5 cm.
- File Size: 10 KB to 40 KB.
- Feature: Face should cover at least 70% of the photo. No caps or sunglasses.
- Recommendation: Use a recent photo showing your natural school appearance.
2. NIOS (Open Schooling) Requirements
The National Institute of Open Schooling is famous for its online-only portal. Since there is no physical paper involved, the digital signature must be very clear.
- Photo size: 20 KB to 50 KB.
- Signature size: 10 KB to 20 KB.
- Identity Proof: Must be uploaded as a PDF or JPG under 200 KB.
3. ICSE/ISC Requirements
The CISCE board typically requires the school to handle uploads, but students must provide high-quality scans.
- Photo Background: Plain white or light blue.
- File Format: Strictly JPG/JPEG.
- Resolution: 300 DPI is recommended for printing on hall tickets.
The "Small File" Challenge
Many students find that when they compress a photo down to 40KB, their face becomes blurry.
Imgverto's Image Compressor uses advanced algorithms that prioritize facial details even at low file sizes. This ensures your CBSE or NIOS photo meets the size limit while staying sharp enough for your official marksheet.
How to Resize for Boards on Your Phone
You can take a photo with your phone camera, use Imgverto's Resize Image tool to crop it to 3.5cm x 4.5cm, and then use the Compress tool to bring it under 40KB. All of this is free and happens right on your device for total privacy.
