BCS, Teletalk & Passport Photo and Signature Size Guide in Bangladesh

The Strict Dimension Challenge in Bangladeshi Government Portals

Every year, hundreds of thousands of applicants submit online job forms across Bangladesh government recruitment portals powered by Teletalk (including the Bangladesh Civil Service - BCS, Primary Teacher Recruitment, Non-Cadre, and Ministry Circulars).

Yet, one of the most common reasons an application is rejected or fails to upload is mismatched photo and signature file specifications.

The Teletalk server enforces rigid binary validation rules:

Applicant Photograph: Strictly 300 × 300 pixels (aspect ratio 1:1), with a file size strictly between 4 KB and 100 KB.
Applicant Signature: Strictly 300 × 80 pixels (aspect ratio 3.75:1), with a file size strictly between 3 KB and 60 KB.
File Format: Must be standard baseline JPEG (.jpg / .jpeg). PNG or WebP formats are immediately rejected by legacy servers.

2. Common Pitfalls & Why Smartphone Photos Fail

When taking a portrait photo or signing on paper with a smartphone:

Phone Photos Are Too Large: Modern phone cameras produce 12MP to 50MP images ranging from 3 MB to 15 MB in size.
Aspect Ratio Distortion: Resizing a 4:3 or 16:9 photo directly to 300 × 300 pixels without cropping stretches or squashes the applicant's face, leading to disqualification during oral viva verification.
Shadows on White Paper: Signatures photographed on desk surfaces suffer from uneven shadows and yellowish indoor lighting, preventing clean binarization.

3. How Client-Side Binary Search Compression Works

To guarantee that an image is both crisp and strictly under 100 KB without uploading sensitive portraits to a remote server, THE SABBiR OS Gov Photo Sizer Studio implements an in-browser binary search JPEG quality compressor:

// Client-side iterative binary search quality compressor
async function compressToTargetKb(
  canvas: HTMLCanvasElement,
  maxKb: number = 100
): Promise<Blob> {
  let minQuality = 0.4;
  let maxQuality = 0.98;
  let bestBlob: Blob | null = null;

  for (let i = 0; i < 6; i++) {
    const midQuality = (minQuality + maxQuality) / 2;
    const blob = await new Promise<Blob>((resolve) =>
      canvas.toBlob((b) => resolve(b!), "image/jpeg", midQuality)
    );

    const sizeKb = blob.size / 1024;
    if (sizeKb <= maxKb) {
      bestBlob = blob;
      minQuality = midQuality; // Try higher quality
    } else {
      maxQuality = midQuality; // Reduce quality
    }
  }

  return bestBlob || canvas.toBlob(...);
}

4. International Visa & Passport Variations

For candidates applying for foreign scholarships, work permits, or tourism visas, different embassies enforce distinct parameters:

Bangladesh E-Passport: 45 × 55 mm (~531 × 650 px at 300 DPI) with white or sky-blue background.
US Visa (DS-160): Exactly 2 × 2 inches (600 × 600 px), head height between 50% and 69% of the frame.
Schengen Visa: 35 × 45 mm, light gray or light blue backdrop with neutral facial expression.
