SBI PO Left Thumb Impression: 240 × 240 Pixels, 20 to 50 KB
The short answer
The SBI PO 2026-27 advertisement asks for your left-hand thumb impression as a JPG or JPEG of 240 × 240 pixels at 200 DPI (3 cm × 3 cm), between 20 KB and 50 KB. Press it on white paper in black or blue ink. If you have no left thumb, you may use the right one.
Copy the numbers from your own exam notice: sizes change from year to year and between exams.
The file is made exactly 240 × 240 pixels and under 50 KB (you are told if it ends up below 20 KB). It is counted as 1 KB = 1,000 bytes, so it fits whether the website counts 1,000 or 1,024.

Frequently asked questions
Which thumb does SBI want?
The left-hand thumb. If you do not have a left thumb, the advertisement lets you use your right thumb instead.
Can SBI use my thumb print later?
The advertisement says the bank may capture a photo and thumb impression, or an iris scan, at various stages for biometric checks, and that an inconsistency can lead to rejection.
My thumb print looks like a black blob. What now?
Too much ink fills the ridges. Wipe the thumb, ink it lightly, and press once without rolling it. Photograph it flat in even light, and use the clean-up option in the tool.
