RBI Grade B left thumb impression: what is specific to this exam
These RBI Grade B 2026 rules come from the RBI notice “Direct Recruitment for the Posts of Officers in Grade ‘B’ (DR) (General/DEPR/DSIM) Cadres – Panel Year 2026, Advt. No. RBISB/DA/01/2026-27”, page 4, last checked on 22 Oct 2026. The RBI Grade B form usually opens around April–May.
From our RBI Grade B notes
- RBI Grade B (DR) applications for Panel Year 2026 ran from 29 April to 20 May 2026. Our values are checked against Appendix-I of the official RBI notice (Advt. No. RBISB/DA/01/2026-27). The photo and signature specs match the standard bank portal. The notice also fixes the KB limits for the left thumb and the handwritten declaration, but not their pixel sizes, so this page marks those two as disputed.
- The Grade B notice lists one "preferred" size, 140×60 px, for the signature, thumb and declaration together. For the thumb and the declaration we use the pixel sizes that RBI's own Assistant notice gives for the same form, 240×240 px and 800×400 px. The KB limits are exactly as printed. If the portal asks for a different pixel size, use the custom size option.
- Use a stamp pad for the thumb; ballpoint ink rubbed on the thumb smudges.
- If the thumb or declaration upload fails with a size error even though our Pass check is green, the portal wants a different pixel size. Read the size from the error message, switch that document to custom size, and fit it again.

RBI Grade B left thumb impression questions
Why are the thumb and declaration marked "disputed"?
The 2026 notice confirms their KB limits (thumb 20–50 KB, declaration 50–100 KB) but lists one "preferred" 140×60 px size for the signature, thumb and declaration together. We use 240×240 px and 800×400 px, the sizes RBI's Assistant notice gives for the same form. If the portal asks for something else, use the custom size option.
Is it the same form for DR General, DEPR and DSIM?
No. The notice asks you to apply through separate links, and pay separately, for DR General and for DEPR or DSIM. The uploads and their sizes are the same in each form.
