Preparing the signature and handwritten declaration correctly is an important part of the State Bank of India (SBI) Probationary Officer (PO) online application process. Even if you have filled in all your personal and educational details accurately, an image file that does not meet the prescribed technical requirements can trigger errors or create verification issues later.

If you are applying for the SBI PO examination for the first time, this guide will help you prepare both files, understand the exact specifications, write the declaration correctly, and upload your documents smoothly without common errors. (If you are also applying for other banking exams, you can also check our guides on IBPS Clerk Handwritten Declaration vs Signature and IBPS PO Signature Size 2026).

What Is an SBI PO Handwritten Declaration?

A handwritten declaration is a brief, formal statement written by the applicant in their own handwriting. Its purpose is to legally certify that all information submitted in the online application is true, complete, and valid, and that original supporting documents will be produced whenever requested by the bank.

It is fundamentally different from a signature:

Your Signature serves as an identity mark to verify that you are the person appearing for the exam and joining the bank.
The Handwritten Declaration acts as a self-attested confirmation of the truthfulness of your application data and allows the bank to verify your handwriting sample.

SBI requires candidates to write the declaration word-for-word as published in the official advertisement.

SBI PO Handwritten Declaration Official Text

For the SBI PO recruitment cycle, the official notification prescribes the following declaration text:

"I________(Name of the candidate), _______(Date of Birth) hereby declare that all the information submitted by me in the application form is correct, true and valid. I will present the supporting documents as and when required. The signature, photograph and left-hand thumb impression is of mine."

Example of Filled Declaration:

If your name is Badal Kumar and date of birth is 12-08-2000, your handwritten declaration should read:

“I Badal Kumar, 12-08-2000 hereby declare that all the information submitted by me in the application form is correct, true and valid. I will present the supporting documents as and when required. The signature, photograph and left-hand thumb impression is of mine.”

[!WARNING]

Write in your own handwriting: Never let anyone else write this for you.

Do NOT use CAPITAL LETTERS: A declaration written entirely in capital (BLOCK) letters is rejected by SBI.

Do NOT alter the text: Do not add or remove words. Stick exactly to the prescribed sentence.

Language: The declaration must be written in English only.

How to Prepare the SBI PO Handwritten Declaration

Follow these step-by-step instructions to create an acceptable declaration file:

  [Step 1: Clean White Paper] 
             ↓
  [Step 2: Write with Black Gel/Ball Pen]
             ↓
  [Step 3: Scan / Photograph in Good Light]
             ↓
  [Step 4: Crop Margins (Leave Padding)]
             ↓
  [Step 5: Resize to 800×400 px, 50-100 KB]
             ↓
  [Step 6: Save as JPG/JPEG & Upload]

Step 1: Take a Clean White Sheet of Paper

Use a plain, unruled A4 white sheet without lines, grids, stains, or background watermarks. Ruled notebook paper can interfere with OCR scanning.

Step 2: Use a Black Ink Pen

Use a clean black ballpoint or gel pen with a bold tip. Avoid blue, red, green, or faint pencil ink. Black ink provides sharp contrast against the white page.

Step 3: Write Clearly in Your Normal Handwriting

Write at a comfortable, natural pace. Ensure adequate spacing between words and letters so every word is distinct and legible.

Avoid these common mistakes:

Writing the entire paragraph in capital letters.
Typing and printing the statement instead of handwriting it.
Overcrowding words to squeeze them into one line.
Omitting your name or date of birth.
Making spelling corrections or overwriting words.

Step 4: Scan or Photograph the Declaration

Place the paper on a flat table under daylight or bright white lighting. You can use a flatbed scanner (set to 200 DPI) or your smartphone. For smartphone tips, check our complete walkthrough on How to Scan Signature Using Mobile for Exam Form.

Keep the camera parallel to the paper to prevent perspective distortion.
Make sure no shadow falls across the text.

Step 5: Crop and Resize the Image

Crop out extra empty paper surrounding the paragraph, leaving a slight, clean border.

Target dimensions: 800 × 400 pixels.
Do not stretch the image disproportionately, which can make the handwriting look warped or blurry. If you run into dimension issues, refer to our guide on Invalid Image Dimensions Error in Exam Form.

Step 6: Save as JPG/JPEG (50 KB to 100 KB)

Save the file as .jpg or .jpeg. Confirm that the final file size sits comfortably between 50 KB and 100 KB. If your file is a PNG, convert it using an image editor rather than merely renaming the extension.

How to Prepare the SBI PO Signature Image

Your signature is compared during the Preliminary Exam, Main Exam, Interview, and final joining. Consistency is vital.

Step 1: Sign on Plain White Paper

Sign with your usual signature on a fresh white unruled sheet using a black ink pen.

Do not sign in capital letters.
Do not use stylized initials that you cannot replicate during the examination hall sign-in.

Step 2: Keep Your Signature Consistent

Use the exact same signature style that appears on your PAN Card, Aadhaar Card, or bank account. A noticeable signature discrepancy between exam stages can lead to scrutiny or disqualification. For more on this, read Government Exam Form Rejected Due to Signature.

Step 3: Scan and Crop

Capture the signature clearly in sharp focus. Crop close to the signature strokes while leaving a small breathing margin.

Step 4: Resize to 140 × 60 Pixels

Use the Signature Resizer tool to set dimensions to 140 pixels wide by 60 pixels high. Maintain the aspect ratio so the signature strokes do not look squished or stretched.

Step 5: Save as JPG (10 KB to 20 KB)

Ensure the final output file is formatted as JPG/JPEG and the size stays within 10 KB to 20 KB. Test opening the file at 100% zoom: if the ink strokes appear pixelated or blurry, see Signature Image Not Clear in Application Form for quick clarity fixes.

Final Thoughts

Preparing your SBI PO signature and handwritten declaration correctly is a small but critical part of your banking application journey. A rejected file or mismatch can delay your registration or even risk disqualification later during verification.

Keep the core rules simple: use a black ink pen on plain white unruled paper, write the declaration in your natural running handwriting (never all caps), resize your signature to 140 × 60 pixels (10–20 KB) and declaration to 800 × 400 pixels (50–100 KB), and save both strictly as JPG/JPEG.

Always verify the exact notification text for your specific recruitment year, and double-check your upload previews before clicking final submit. Taking ten minutes to prepare your documents properly gives you peace of mind so you can focus entirely on your exam preparation.
