Understanding CAT Signature Sizing Specifications
During the online registration process for Common Admission Test, candidates are required to upload their documents matching strict criteria. For CAT, the official signature requirements are: Under 80KB, 35mm x 80mm in JPG format. If the file size or dimensions exceed these bounds, the portal will show a validation error, potentially delaying your application.
How to Hit the Sizing Target Correctly
- Crop first: If compressing a photo or signature, crop it tightly around the subject area to remove blank space. This saves file size.
- Use standard formats: Ensure you export in the correct extension (e.g. .jpg or .pdf) matching the specifications.
- Check readability: For signatures and documents, verify that the text remains sharp and legible before submitting.
