SSC, UPSC & Railway Exam Photo Size, Ratio, KB Limit & 200x230 Pixel Guide

Every year, over 2.5 crore aspirants across India register for premier competitive examinations conducted by the Staff Selection Commission (SSC), Union Public Service Commission (UPSC), Railway Recruitment Boards (RRB), Institute of Banking Personnel Selection (IBPS), and the National Testing Agency (NTA).

Alarmingly, official post-scrutiny data indicates that up to 7% to 10% of total applications are rejected outright during the preliminary verification stage simply because of non-compliant photographs and signatures. Whether it is an invalid pixel box (e.g. failing to submit the exact $200 \times 230\text{ px}$ frame), incorrect signature dimensions ($6.0 \times 2.0\text{ cm}$), blurred pen strokes, wearing spectacles, or exceeding strict file size limits (like 20 KB or 50 KB), minor oversights can cost an entire year of hard-earned preparation.

In this definitive guide, we provide the complete, updated examination board matrix, technical specifications, signature requirements, and step-by-step instructions to format your examination photo and signature effortlessly.

1. Master Examination Photo & Signature Specification Matrix

The table below summarizes the exact photographic and digital upload standards mandated by major Indian examination recruitment agencies:

2. Staff Selection Commission (SSC) Application Guidelines

Staff Selection Commission has recently overhauled its candidate recruitment architecture with the new portal (ssc.gov.in) and the official MySSC mobile application.

Exact 200 × 230 Pixel Box

For examinations that permit direct photo uploads (or during correction windows), SSC enforces a strict digital box of 200 pixels width by 230 pixels height. This corresponds mathematically to an aspect ratio of approximately 7:9 (or 0.87 width-to-height ratio). If you upload a wider 16:9 picture or square 1:1 image without cropping, the portal engine will distort your facial features, potentially causing biometric mismatch at the computer-based test (CBT) examination center.

Live Camera Capture Rules (MySSC App / Web)

For recent recruitment notifications such as SSC CGL, CHSL, and SSC JE, candidates are prompted to capture a live photograph through a webcam or mobile camera:

1. Plain Background: You must sit against an uninterrupted, plain white or light-coloured wall. Do not stand in front of curtains, door frames, or outdoor foliage.
2. Proper Frontal Lighting: Ensure light falls directly on your face without casting shadows behind your ears or under your nose.
3. No Accessories: Candidates must remove all spectacles, sunglasses, caps, and scarves. Even if you wear power spectacles daily, you must remove them for the live capture.
4. Neutral Expression: Look straight into the camera lens with both eyes open and mouth closed.

SSC JE Signature Dimensions: 6.0 cm × 2.0 cm (10 KB to 20 KB)

While photos have a wider tolerance (20 KB to 50 KB), the SSC signature file size is strictly clamped between 10.0 KB and 20.0 KB:

• Format: JPG / JPEG only.
• Aspect Ratio: $6.0\text{ cm (Width)} \times 2.0\text{ cm (Height)}$ (locked 3:1 ratio).
• Ink Color: Dark blue or black ink on clean white unruled paper.
• Handwriting Rule: The signature must be in your natural running cursive handwriting. Signatures in ALL CAPITAL / BLOCK LETTERS (e.g., “RAHUL SHARMA”) will be rejected without any opportunity for correction.

3. Union Public Service Commission (UPSC) One Time Registration (OTR) Rules

The Union Public Service Commission portal (upsconline.nic.in) manages the prestigious Civil Services Examination (CSE), NDA, CDS, and Engineering Services (ESE).

The 10-Day Recency Mandate

UPSC mandates that the candidate photograph uploaded to the One Time Registration (OTR) profile must not be more than 10 days old from the date of online application submission.

Name and Date on Photograph

1. The photograph must clearly display the candidate’s name and the date on which the photograph was taken printed in clean black letters on a white strip at the bottom of the photo.
2. The candidate’s facial features should occupy at least 3/4th (75%) of the space in the photograph.
3. If a candidate sports a beard or moustache at the time of photograph capture, they must maintain the same appearance throughout the preliminary, mains, and personality test stages.

Pixel and File Size Range

• Minimum Resolution: $350 \times 350\text{ pixels}$.
• Maximum Resolution: $1000 \times 1000\text{ pixels}$.
• File Size: Strictly between 20 KB and 300 KB in JPEG format.

To crop your photo into a precise square format with high pixel density, use our 2×2 Inch / Square Ratio Guide.

4. Railway Recruitment Board (RRB) Specifications

The Railway Recruitment Board administers massive recruitment drives across 21 regional zones for positions including Junior Engineer (RRB JE), Assistant Loco Pilot (ALP), and Non-Technical Popular Categories (NTPC).

Key Photographic Criteria

• Physical Size: $35\text{ mm} \times 45\text{ mm}$ ($3.5 \times 4.5\text{ cm}$).
• Digital Resolution: $240 \times 320\text{ pixels}$ at 300 DPI.
• File Size Window: 30 KB to 70 KB (JPEG).
• Signature Window: 10 KB to 40 KB ($6.0 \times 2.0\text{ cm}$ or $5.0 \times 2.0\text{ cm}$).
• Neutral Background: Pure white background without textures or reflections.

5. Five Major Reasons for Application Rejections (And How to Avoid Them)

graph TD
    A[Application Submission] --> B{Biometric Verification}
    B -->|Dark / Shadowed Background| C[REJECTED]
    B -->|Wearing Spectacles / Goggles| D[REJECTED]
    B -->|Signature in Capital Letters| E[REJECTED]
    B -->|File Size < 10KB or > 20KB| F[REJECTED]
    B -->|White BG, Clear Ratio, Running Hand| G[APPROVED ✅]

1. Blurred or Pixelated Scans

Taking a blurry photo with poor lighting or repeatedly re-saving a JPEG on WhatsApp degrades pixel fidelity. Always use our client-side Passport Photo Maker Studio which performs lossless canvas resizing.

2. Signatures in Capital / Block Letters

Staff Selection Commission and Railway boards specifically state in their recruitment brochures: “Applications with signatures in capital letters will be rejected.” Always sign in a fluid cursive style.

3. Wearing Spectacles, Caps, or Headgear

Unless required for genuine religious practices (such as Sikh Turbans or Muslim Hijabs, provided the full face from forehead to chin is unobstructed), all headwear and spectacles must be removed.

4. Over-Compressed Files Under 10 KB

Many online compressors crush image files down to 5 KB to 8 KB, resulting in blocky artifacts and immediate server errors. Our tool guarantees output within the target zone (e.g. 11 KB to 19 KB for SSC signatures).

5. Camera Shadows on Paper Signatures

Holding a phone directly above a signature casts a dark grey shadow across the paper. Our built-in Signature High-Contrast B&W Mode automatically thresholds the image, rendering the paper pure white ($#FFFFFF$) and ink lines deep black ($#000000$).
