SSC GD Signature Size 2026-27, Photo & Signature Size

The SSC GD signature size is an important requirement while filling out the Constable GD application form. A blurred, miniature, wrongly sized or improperly aligned signature can create problems during application submission. Based on the latest available SSC GD instructions, candidates should upload their scanned signature in JPEG format with a file size between 10 KB and 20 KB and dimensions of approximately 6.0 cm × 2.0 cm.

In this blog, candidates can check the SSC GD signature size in cm, file size, format, photo requirements, common upload errors and steps to resize the signature. We have also explained how to use an SSC GD signature size converter without affecting the clarity of the image.

What is the SSC GD Signature Size?

The SSC GD signature must meet the file-size and dimension requirements prescribed by the Staff Selection Commission under SSC GD Notification. Candidates should prepare the signature before starting the application so that they do not face upload errors at the final stage. The latest available SSC GD application instructions specify the following signature requirements:

Particulars	SSC GD Signature Requirement
File Format	JPEG
File Size	10 KB to 20 KB
Signature Width	About 6.0 cm
Signature Height	About 2.0 cm
Orientation	Horizontal
Signature Quality	Clear and readable
Blurred Signature	Not acceptable
Miniature Signature	Not acceptable

What is the SSC GD Signature Size in CM?

Candidates wanting to know about the SSC GD signature size in cm should use approximately 6.0 cm width and 2.0 cm height while preparing the scanned signature. The size in centimetres and file-size requirement should both be followed. Simply keeping the image under 20 KB is not enough if the signature becomes too small or unreadable.

Measurement	Required Size
Width	Approximately 6.0 cm
Height	Approximately 2.0 cm
Aspect Ratio	Around 3:1
File Size	10–20 KB
Format	JPEG

What is the SSC GD Signature Size in KB?

The scanned signature should have a file size between 10 KB and 20 KB. Candidates should avoid excessive compression merely to reduce the file size. If compression makes the signature blurred or difficult to read, the image may not meet the prescribed requirement.

File Size	Status
Below 10 KB	Does not meet the prescribed range
10–20 KB	Required range
Above 20 KB	Needs resizing/compression

What is the SSC GD Signature Size in Pixels?

SSC’s latest available GD instructions specify the signature dimensions in centimetres, not a mandatory pixel dimension. Therefore, candidates should not treat a random pixel value shown on third-party websites as an official SSC requirement. Pixel dimensions depend on the resolution or DPI used while creating the image.

Requirement	Official Status
6 cm × 2 cm	Specified by SSC
10–20 KB	Specified by SSC
JPEG Format	Specified by SSC
Fixed Pixel Dimension	Not specified in the latest available SSC GD notice

What is the SSC GD Photo and Signature Size?

The SSC GD photo and signature size requirements are different because SSC’s current application system captures the candidate’s photograph live. Candidates do not need to upload a pre-existing passport-size photograph under the latest application process. The application module captures the photograph through the computer or mobile camera, while the signature must be uploaded separately.

Document	Requirement
Photograph	Captured live through SSC application module
Pre-existing Photo Upload	Not required under the latest process
Signature Format	JPEG
Signature Size	10–20 KB
Signature Dimensions	About 6 cm × 2 cm
Signature Alignment	Horizontal

What are the SSC GD Live Photo Requirements?

SSC currently captures the candidate’s photograph during the online application process. Candidates should take the live photograph carefully because an unclear or incorrectly captured photograph may create issues with the application. SSC advises candidates to follow these points:

• Use a place with good lighting.
• Keep a plain background.
• Keep the camera at eye level.
• Look directly at the camera.
• Keep the entire face within the area shown on the screen.
• Do not position the face too close or too far from the camera.
• Do not wear a cap.
• Do not wear a mask.
• Do not wear glasses or spectacles.
• Ensure that the photograph shows a clear frontal view.

How should you make the SSC GD Signature?

Candidates should use their normal signature and scan or photograph it clearly before resizing. The final image should look natural and remain easy to identify. A simple process is given below:

1. Sign clearly on clean white paper using a dark pen.
2. Keep enough space around the signature.
3. Scan or take a clear image of the signature.
4. Crop unnecessary blank space.
5. Keep the signature horizontally aligned.
6. Resize it to approximately 6 cm × 2 cm.
7. Save the image in JPEG format.
8. Compress the file to between 10 KB and 20 KB.
9. Open the final image once again and check its clarity.
10. Upload only after confirming that the signature is clearly readable.

How can you use an SSC GD Signature Size Converter?

An SSC GD signature size converter can be used to resize and compress the scanned signature before uploading it to the SSC GD Application Form. Candidates should enter the correct requirements rather than using automatic settings that may reduce the image excessively.

Converter Setting	What to Select
Output Format	JPEG
Width	Approximately 6 cm
Height	Approximately 2 cm
Target File Size	10–20 KB
Orientation	Horizontal
Quality	Keep high enough for a clear signature

How can you reduce SSC GD Signature Size to 10–20 KB?

If the scanned signature is larger than 20 KB, candidates can reduce its size without changing the signature itself. Use the following steps:

• Crop unnecessary white space around the signature.
• Resize the image to approximately 6 cm × 2 cm.
• Save it as JPEG rather than PNG.
• Use moderate JPEG compression.
• Check the file size after every resize.
• Stop compressing once the file reaches the 10–20 KB range.
• Check the image visually before uploading.

What should you check before uploading the SSC GD Signature?

Candidates should preview the signature before submitting the application form. A quick check can prevent avoidable application errors.

Check	What to Confirm
Format	Image is saved as JPEG
File Size	Between 10 KB and 20 KB
Dimensions	Approximately 6 cm × 2 cm
Alignment	Signature is horizontal
Visibility	Signature is clearly readable
Image Quality	Not blurred or pixelated
Size of Signature	Not miniature
Cropping	Complete signature is visible

Why does SSC Reject a Signature?

SSC specifically warns candidates about inappropriate, blurred and miniature signatures. A technically correct file size does not guarantee acceptance if the signature itself cannot be read properly. Common reasons for signature-related problems include:

• Signature is too small.
• Image is blurred.
• Signature is cropped from the edges.
• File size is outside 10–20 KB.
• Incorrect image format is used.
• Signature is uploaded vertically.
• Excessive compression affects clarity.
• Large blank margins make the actual signature appear miniature.
• The uploaded image does not contain a proper signature.

What Does a Miniature Signature Mean in SSC GD?

A miniature signature means the actual signature occupies only a very small portion of the uploaded image. This can happen when candidates scan an entire sheet of paper instead of cropping around the signature. For example, an image may technically measure 6 cm × 2 cm, but if most of the image is empty white space, the actual signature can appear extremely small. To avoid this:

• Crop excess white space.
• Keep reasonable margins around the signature.
• Make sure the signature occupies most of the usable image area.
• Preview the uploaded image before submission.

Can a Blurred SSC GD Signature Cause Application Rejection?

Yes. Candidates should not upload a blurred or illegible signature. SSC’s application instructions state that applications containing inappropriate, blurred or miniature signatures that do not meet the prescribed requirements may be rejected. Use a clear original image and avoid aggressive compression.

Should the SSC GD Signature be horizontal?

Yes. The latest official instructions state that the signature should be horizontally aligned. Candidates should therefore avoid:

• Vertical signatures
• Rotated images
• Tilted scans
• Upside-down signatures

Can you upload a PNG Signature for SSC GD?

Candidates should use JPEG, as prescribed by SSC. Even if the application portal technically accepts another format at some stage, candidates should follow the format mentioned in the official instructions rather than relying on trial and error.

Format	Recommended for SSC GD
JPEG/JPG	Yes, as prescribed
PNG	Do not use unless SSC specifically permits it
PDF	No
HEIC	No

Can you upload a Mobile-Scanned Signature for SSC GD?

A mobile phone can be used to create a clear image of the signature, provided the final file meets all SSC requirements. Candidates should:

• Place the signed paper on a flat surface.
• Use good lighting.
• Avoid shadows.
• Keep the phone directly above the signature.
• Crop the image properly.
• Resize it to approximately 6 cm × 2 cm.
• Save it as JPEG.
• Keep the file between 10 KB and 20 KB.

Does Aadhaar Authentication affect SSC GD Photo and Signature rejection?

The latest SSC GD instructions provide an important relaxation for candidates who opt for Aadhaar-based authentication. The notice states that applications submitted through Aadhaar authentication will not be rejected solely because the photograph or signature does not meet the prescribed standards.

Application Method	Photo/Signature Provision
Without Aadhaar Authentication	Candidates must strictly follow prescribed standards
With Aadhaar Authentication	Application is not rejected solely on photo/signature-standard grounds

Can you change the SSC GD Signature after final submission?

Candidates should correct the signature before final submission wherever the application system allows preview or editing. Once the application has been finally submitted, changes depend on the correction facility provided by SSC for that recruitment cycle. Candidates should not assume that every field or uploaded image can necessarily be changed later. Therefore, check the signature carefully during the preview stage before submitting the form.

What are the Common SSC GD Signature Upload Errors?

Most signature problems are caused by resizing, file format or image clarity rather than the signature itself.

Problem	Solution
File above 20 KB	Compress or resize the JPEG
File below 10 KB	Save at slightly higher quality
Signature looks tiny	Crop excess white space
Signature is blurred	Start again from a clearer scan
Image is vertical	Rotate and save horizontally
Wrong format	Convert to JPEG
Edges are cut	Re-crop with small margins
Upload error	Recheck format, size and internet connection
