Bihar Police Photo & Signature Requirements (2026)
CSBC constable specs, the BPSSC SI difference, and the face-coverage rule.
Bihar Police recruitment splits across two boards with different upload rules: CSBC handles constable posts with a 3.5×4.5 cm photo and 4×2 cm signature, while BPSSC handles sub-inspector posts with a smaller pixel-based spec. Applicants who prepare one set for both are the ones who get stuck. CSBC also checks that the face fills 50–60% of the frame with both ears visible, and that the photo is under six months old.
