CTET Photo & Signature Size
The photo and signature limits to aim for when you fill the CTET or a state TET form, and a quick way to hit them.
PhotoResizer's CTET / TET preset uses a photo of 10–100 KB at 350 × 450 px and a signature of 3–30 KB at 350 × 150 px, both JPEG. Always compare with the official notification before you upload.
Teacher eligibility tests are filled in by lakhs of candidates, often from a phone and often close to the last date. That is the worst moment to find out that your signature is 400 KB or that the photo looks stretched.
The values below are the CTET / TET preset in PhotoResizer. They give you a sensible target, then the notification has the final say.
Sizes in the PhotoResizer CTET / TET (Teachers) preset
| Requirement | Photograph | Signature |
|---|---|---|
| Format | JPEG | JPEG |
| File size | 10 KB – 100 KB | 3 KB – 30 KB |
| Dimensions | 350 × 450 px | 350 × 150 px |
The signature range is unusually low
The signature range in this preset starts at only 3 KB, which is much lower than most exam forms. That is because a clean signature on white paper compresses very small. If your signature file lands in the low single digits, it is usually fine as long as the strokes are still readable when you zoom in.
How to resize your photo and signature
- Keep your originals — Use the unedited photo and the scan or picture of your signature, not copies that have already been compressed.
- Open PhotoResizer — Choose the CTET / TET (Teachers) preset from the exam list, or enter custom values if your notification differs.
- Upload and check the preview — Add the photo, then the signature, one at a time. Look at the preview before you accept it.
- Download and check the size — Save the JPEG files and confirm the KB size in your file manager before uploading to the form.
Practical tips
- Photograph the signature on plain white paper with a black or blue pen and crop tight around it, so the pixel budget is not wasted on empty paper.
- For the photo, keep your head centred and your face unobstructed. Do not use a filter or a heavily edited picture.
- If you also apply to KVS or NVS, note that PhotoResizer has a separate preset for them with a different signature range. Choose the preset that matches the form in front of you.
Frequently asked questions

It tries to land inside the KB range while keeping as much detail as possible. Preview the result before you download.
