Assuming RRB specs never change between cycles can lead to a mismatched upload — always check the current notification.

RRB Group D recruits for a wide range of entry-level railway posts and typically draws one of the largest applicant pools of any RRB exam. Its photo and signature specification now matches RRB NTPC exactly — a 200×230 pixel photo between 20KB and 50KB, and a 140×60 pixel signature between 10KB and 20KB, both JPEG. If you've already prepared files for an NTPC application in the same cycle, the same files work here too — just double-check both against your current notification since RRB specs are occasionally revised between cycles.
Frequently asked questions
Is the RRB Group D photo size the same as NTPC?
Yes — both now use 200×230px, 20-50KB for the photo and 140×60px, 10-20KB for the signature.
