Getting a thumb impression to 240 x 240 and 20 KB to 50 KB
SBI's recruitment notice asks for your left thumb impression in black or blue ink on white paper, 240 x 240 pixels preferred, with a file size between 20 KB and 50 KB, as a JPG or JPEG.
Here the image is cropped square where you place the crop box, resized to 240 x 240, saved at the best quality under 50 KB, and padded up to 20 KB with an invisible comment inside the file if it comes out smaller.
Tips
- Press the thumb once, firmly and evenly, so the ridges are clear rather than a smudge.
- Photograph it straight on in good light and crop close around the print first, so the square crop keeps all of it.
- If you do not have a left thumb, the notice allows your right thumb.

Questions
What is the SBI left thumb impression size in cm?
SBI asks for 240 x 240 pixels at 200 DPI, which it states as 3 cm x 3 cm, between 20 KB and 50 KB, as a JPG or JPEG. Here the image is cropped square to 240 x 240 and padded up to 20 KB if it comes out under the minimum.
Does SBI check my thumb impression at the exam?
SBI may capture your thumb impression or iris digitally at various stages for biometric verification, and any inconsistency leads to rejection of your candidature. The notice advises against applying mehandi, ink or chemicals on your hands, so the thumb you upload should be the one you can present later.
What if my uploaded SBI thumb impression is smudged?
SBI says an unclear or smudged thumb impression may get your application rejected. After uploading, check the preview. If the print is not prominently visible, you can edit the application and upload a clearer image. Your application is not registered until the thumb impression is uploaded as specified.
