Bihar Police Constable Photo: 35mm × 45mm, JPEG, max 50KB (no confirmed minimum — see below). Signature: 40mm × 20mm, JPEG, 15KB–25KB — and you need TWO signature files, one in English and one in Hindi. Use our free resizer tool to get both sizes right instantly.
Bihar Police Constable Photo Specifications 2026
The Central Selection Board of Constable (CSBC) — the body that conducts Bihar Police Constable recruitment — follows a standard passport-style photo requirement: 35mm × 45mm, in JPEG format, with a file size capped at 50KB. This pattern is consistent across CSBC's own notification history and cross-checked against independent resizing-reference sources. Where the pattern is honestly incomplete is the minimum file size — no source, including CSBC's own materials, reliably confirms a floor, so we don't invent one here. Aim for a clear, well-lit photo comfortably under 50KB rather than chasing a specific minimum number.
| Parameter | Required Value | Status |
|---|---|---|
| Dimensions | 35mm × 45mm (3.5cm × 4.5cm) | Confirmed |
| File Format | JPEG / JPG only | Confirmed |
| File Size — Maximum | 50 KB | Confirmed |
| File Size — Minimum | Not confirmed by any source | Unstated — don't guess |
| Background | White or light, plain background | Confirmed |
Bihar Police Constable Signature Specifications 2026 — English AND Hindi
This is the part of the Bihar Police Constable application that genuinely trips candidates up, and it's not something you'll see on any other exam covered on this site: CSBC's application form has two separate signature upload fields — one for your signature written in English script, and a second, distinct one for the same signature written in Hindi (Devanagari) script. Both go through the same dimension and file-size requirement, but they are two different image files, signed and scanned separately.
| Parameter | Required Value (applies to BOTH signatures) |
|---|---|
| Dimensions | 40mm × 20mm (4cm × 2cm) |
| File Format | JPEG / JPG only |
| File Size Range | 15 KB – 25 KB |
| Number of Files Required | Two — one signed in English, one signed in Hindi |
| Background | Plain white paper |
Many candidates prepare a single signature image, resize it correctly, and are ready to submit — then hit CSBC's second upload field asking for the same signature in Hindi, and scramble at the last minute. If Hindi isn't your everyday signing script, practice writing your name in Devanagari a few times on paper before you scan it, so it looks natural rather than laboured. Prepare and resize both files ahead of time — English and Hindi — so neither upload field catches you unprepared on submission day.

Open Bihar Police Resizer →Why This Matters: Over 5,000 Forms Rejected in a Recent Cycle
Reports from a recent Bihar Police Constable recruitment cycle put the number of forms rejected specifically for photo and signature specification errors at over 5,000 — a substantial share of applicants losing their shot at the exam over something entirely avoidable. With the added complexity of two separate signature uploads, Bihar Police Constable has more surface area for a small mistake than most other exams on this site, which is exactly why it's worth double-checking both files against the exact spec before you submit.
Common Mistakes With Bihar Police Constable Photos
Do's
- Prepare and resize BOTH signature files — English and Hindi — before you start filling the form, so you're not scrambling when the second upload field appears
- Keep the photo at 35mm × 45mm exactly, and comfortably under the 50KB maximum
- Use a plain white background for both the photo and the signature scans
- Practice your Hindi (Devanagari) signature on paper a few times if it isn't your usual signing script, so it reads naturally rather than hesitant
Don'ts
- Don't assume one signature file will satisfy both upload fields — CSBC requires two genuinely separate files
- Don't leave the Hindi signature until the last minute — it's easy to underestimate how long it takes to get a natural-looking Devanagari signature
- Don't compress the photo so hard it looks blurry or pixelated just to undershoot 50KB — clarity matters for verification later
- Don't reuse a signature scan prepared for a different exam without checking it against CSBC's own 40mm × 20mm, 15–25KB requirement
Exam specifications may change with each new CSBC notification. Always cross-check with the latest official Bihar Police Constable notification on csbc.bih.nic.in before submitting your application.

बिहार पुलिस कांस्टेबल फोटो साइज़ — हिंदी में जानकारी
बहुत से उम्मीदवार पूछते हैं — बिहार पुलिस कांस्टेबल फोटो का साइज़ कितना होना चाहिए? जवाब है: फोटो 35mm × 45mm की, JPEG फॉर्मेट में होनी चाहिए, और फाइल साइज़ अधिकतम 50KB तक होना चाहिए। ध्यान रहें — किसी भी विश्वसनीय स्रोत में न्यूनतम साइज़ की पुष्टि नहीं है, इसलिए हम कोई गलत आंकड़ा नहीं देंगे — बस फोटो को साफ़ रखें और 50KB से नीचे रखें।
सिग्नेचर का साइज़ 40mm × 20mm होता है, फाइल साइज़ 15KB से 25KB के बीच। सबसे ज़रूरी बात — CSBC के फॉर्म में दो अलग सिग्नेचर अपलोड करनी होती हैं: एक अंग्रेज़ी में और एक हिंदी में। यह नियम इस साइट पर मौजूद किसी और एग्ज़ाम में नहीं है, इसलिए दोनों सिग्नेचर पहले से तैयार करके रखें, ताकि फॉर्म भरते समय अटकना न पड़े।
