This is the single most important thing to understand before searching for "CBSE photo size" — and it's different from every other exam covered on this site. CBSE Class 10 and 12 registration doesn't work through a student-facing portal like SSC or IBPS. Your school submits your photo, signature, and details through a process called the LOC (List of Candidates), on your behalf.
What the LOC (List of Candidates) Process Actually Is
Every CBSE-affiliated school logs into its own school-facing CBSE IT portal and submits a List of Candidates (LOC) — one consolidated submission covering every eligible student in that school, for that exam cycle. As part of this, the school uploads each student's stamp-size photograph and signature, along with their academic and personal details.
This means you, as a student, never log into a CBSE application portal yourself and never personally handle a file upload for your board exam registration the way you would for a competitive exam. What you do instead is provide your school's exam coordinator or class teacher with a photo and signature when they ask for it — usually early in the academic year, well before the LOC submission deadline.
Why We Can't Give You an Exact KB/mm Number — and Why That's Honest, Not Lazy
Every other guide on this site gives you an exact millimetre dimension and KB file size, because those specs are published in a public notification meant for the student uploading their own photo. CBSE's LOC portal is different: it's built for school administrators, not students, and its exact technical upload specification isn't published in a general public-facing notification the way SSC's or UPSC's is.
The honest, useful answer is this: the commonly used reference size across Indian school and government documentation is a standard "stamp-size" or passport-size photograph, generally recognised as around 35mm × 45mm. If your school asks you for a digital photo to submit on your behalf, preparing one to that standard is a safe, widely-accepted default — but it is not an officially published CBSE LOC specification, and your school's exam coordinator is the actual source of truth for whatever format they need from you.
| What | What We Know |
|---|---|
| Who uploads the photo | Your school, via the LOC portal — not you directly |
| Commonly used reference size | "Stamp-size" / passport-size, generally ~35mm × 45mm (not an officially published CBSE LOC number) |
| Who to ask for the exact spec | Your school's exam coordinator or class teacher — they operate the actual upload |
| APAAR ID | Mandatory for 2026 registration — schools can only submit your LOC once your APAAR ID exists |
| Correction window | None for 2026 — CBSE has stated no corrections are allowed after LOC submission |
The APAAR ID Requirement — New for 2026
CBSE has made APAAR ID (Automated Permanent Academic Account Registry) mandatory for Class 10 and 12 registration starting the 2026 exam cycle. Schools can only include a student in the LOC submission once that student's APAAR ID has been generated — so this is worth resolving with your school well ahead of the LOC deadline, not something to leave until the last minute alongside your photo and signature.
CBSE has tightened LOC submission rules for 2026 — once your school submits the list of candidates, no corrections are permitted. This makes it more important than usual to double-check every detail your school has on file for you, including your name, date of birth, subject combination, and the photo/signature they'll be submitting, before their internal deadline.
Prepare a standard passport-size photo — free
If your school asks you for a digital photo to submit on your behalf, our resizer can prepare one to the standard 35mm × 45mm passport-photo format used across most Indian government forms.
Open the Resizer →What Students Should Actually Do
Do's
- Ask your school's exam coordinator or class teacher directly what digital photo/signature format they need from you — they operate the actual CBSE portal, so they're the real source of truth
- Make sure your APAAR ID is generated well before your school's internal LOC deadline, since 2026 registration requires it
- If your school also asks for physical passport-size photographs (many still do, for records or the admit card printed by the school), keep a few of the standard 35mm × 45mm size on hand
- Double-check your name, date of birth, and subject combination with your school's records before their LOC submission — there's no correction window for 2026
Don'ts
- Do not assume you need to personally log into a CBSE website and upload a photo — this is a common misconception carried over from competitive exam applications
- Do not wait until CBSE's official LOC deadline — schools set their own earlier internal deadline to leave time for processing, and missing it can be far more disruptive than missing a single online form field
- Do not submit a blurry or outdated photo to your school for 2026 — since corrections aren't allowed after LOC submission, there's no fixing it afterward
- Do not search for a "CBSE photo upload portal" expecting a student-facing website — it doesn't work that way for board exam registration
CBSE बोर्ड एग्ज़ाम फोटो — हिंदी में जानकारी
बहुत से छात्र सोचते हैं कि CBSE बोर्ड एग्ज़ाम के लिए भी SSC या IBPS की तरह खुद फोटो अपलोड करनी होती है — लेकिन ऐसा नहीं है। CBSE क्लास 10 और 12 के रजिस्ट्रेशन में आपका स्कूल LOC (List of Candidates) प्रोसेस के ज़रिए आपकी फोटो, सिग्नेचर और डिटेल्स जमा करता है।
चूंकि यह पोर्टल स्कूल एडमिनिस्ट्रेटर्स के लिए बना है, इसका सटीक साइज़ (mm/KB) सार्वजनिक रूप से नहीं बताया जाता। आमतौर पर स्टैम्प-साइज़ या पासपोर्ट-साइज़ फोटो (लगभग 35mm × 45mm) का इस्तेमाल होता है, लेकिन सही जानकारी के लिए अपने स्कूल के एग्ज़ाम कोऑर्डिनेटर से ज़रूर पूछें। 2026 से APAAR ID भी अनिवार्य कर दी गई है, और LOC जमा होने के बाद कोई सुधार नहीं हो सकता — इसलिए समय रहते सब कुछ चेक कर लें।
अगर स्कूल आपसे डिजिटल फोटो मांगता है, तो SarkariKagaz.pro का फ्री रीसाइज़र इस्तेमाल करके एक स्टैंडर्ड 35mm × 45mm पासपोर्ट-साइज़ फोटो तैयार करें — यह टूल पूरी तरह मुफ़्त है और फोटो कभी भी किसी सर्वर पर अपलोड नहीं होती।
