SSC Photo and Signature Size 2026 — CGL, CHSL, GD, MTS Upload Guide
Every year, lakhs of SSC candidates fill out their application forms only to get stuck at the photo upload step. The portal throws a vague error, the photo looks fine on your phone, and you're left wondering what went wrong. Nine times out of ten, it's a size or format issue that takes two minutes to fix — if you know the exact specs.
SSC Photo Specifications — All Exams
SSC keeps things mostly consistent across CGL, CHSL, GD Constable, MTS, and CPO. Your photo should be 3.5 cm x 4.5 cm, which translates to roughly 413 x 531 pixels. File size must be between 20 KB and 50 KB. Format is JPEG/JPG only. The background should be white, and the photo must be recent — taken within the last three months.
SSC Photo — Quick Specs
Dimensions: 3.5 × 4.5 cm (413 × 531 pixels)
File size: 20 KB to 50 KB
Format: JPEG/JPG only
Background: White
No name/date stamp on photo
Signature: 3.5 × 1.5 cm | 10–20 KB | Black ink on white paper
One important detail that SSC specifically mentions: there should be no date or name printed on the photo. Some photo studios stamp the date on the bottom — make sure yours doesn't. If it does, you'll need to crop that part out before resizing.
SSC Signature Specifications
Your signature file needs to be 3.5 cm x 1.5 cm, between 10 KB and 20 KB, in JPEG format. Sign with a black ball-point pen on clean white paper. Don't use gel pens or felt tips — they bleed and create uneven thickness that doesn't scan well.
Here's something that catches first-timers: SSC may also ask for a left thumb impression. If required, it should be on white paper with black or dark blue ink, same size range as the signature. Check the specific exam notification because this requirement varies.
The 20-50 KB Sweet Spot
This is probably the tightest file size window among all government exams. You only have a 30 KB range to work with, and that's where most people struggle. A photo straight from your camera might be 3-5 MB. A studio JPEG might be 200-500 KB. You need to bring that down to under 50 KB without making it look like it was taken on a 2005 flip phone.
The trick is to resize first, then compress. Resize to the exact pixel dimensions (413 x 531), and you'll find the file size drops dramatically — often to 60-80 KB. Then a light compression pass with a JPG compressor targeting 50 KB brings it into range without visible quality loss. If you compress before resizing, you're degrading quality unnecessarily.
How to Resize Your Photo — Step by Step
Open an image resizer tool and upload your photo. Set width to 413 pixels and height to 531 pixels. If the tool has an aspect ratio lock, you might need to unlock it since your source photo probably isn't in a 3.5:4.5 ratio. After resizing, check the preview — your face should be centred with a small margin of white space above your head.
Resize to SSC Dimensions
Set your photo to exactly 413 × 531 pixels — the standard dimensions for all SSC exams including CGL, CHSL, and GD.
If the photo looks stretched or squeezed, that means your original wasn't cropped properly. Go back and crop it to a 7:9 ratio first (which is the same as 3.5:4.5), then resize. Cropping before resizing always gives a better result than trying to force a differently-shaped photo into the required dimensions.
Common SSC Upload Errors and Fixes
"File size exceeds the limit" — Your image is over 50 KB. Compress it further. If you're already at the minimum quality and still over 50 KB, your pixel dimensions are probably too large. Resize to exactly 413 x 531. "File size too small" — You've compressed too aggressively and dropped below 20 KB. Use a slightly higher quality setting or start with a better source photo.
"Invalid file format" — You're uploading a PNG, HEIC, or WebP file. iPhones save photos as HEIC by default, which SSC doesn't accept. Convert HEIC to JPG before uploading. "Image dimensions not matching" — Some SSC portals validate pixel dimensions. Double-check that your final file is exactly the right size.
SSC vs UPSC vs RRB — Don't Mix Them Up
If you're appearing for multiple exams — and most serious government job aspirants do — keep separate photo files for each. SSC wants 3.5 x 4.5 cm at 20-50 KB. UPSC wants 4 x 5 cm at 20-300 KB. Railway RRB wants 35 x 45 mm at 15-40 KB (similar to SSC but with a tighter upper limit). IBPS wants 200 x 230 pixels at 20-50 KB.
Create a folder on your phone or computer called something like "Exam Photos 2026" and save each version with a clear filename — like ssc_photo_413x531_45kb.jpg. When the next exam notification drops and you're filling the form at midnight before the deadline, you'll thank yourself for being organized.
Pro Tips From Candidates Who've Been Through It
Always upload well before the deadline. SSC portals slow down massively on the last two days, and upload errors become more frequent when the server is under load. Test your photo by uploading it and checking the preview — if it looks clear in the preview, you're good.
Keep your original unedited studio photo. Every exam cycle, you'll need to create fresh versions, and starting from a high-quality original always beats working with an already-compressed file. If your studio gives you a soft copy, ask for the highest resolution available — it costs nothing extra and gives you much more flexibility for different exams.
One last thing: make sure the photo you upload matches how you'll look on exam day. If you've grown a beard since the photo was taken, or cut your hair significantly, get a fresh photo. The invigilator compares your admit card photo with you in person, and a mismatch can create unnecessary problems.
Studio Photo vs Phone Photo — What Works Better
A professional studio photo is ideal, but a smartphone photo can work just as well. The key factors are lighting and background. Natural daylight from a window gives even illumination without harsh shadows. Stand about 1.5 metres from a clean white wall. Use your phone's rear camera (not the selfie camera — it distorts facial proportions at close range) and ask someone else to take the photo.
Studio photos cost ₹50-200 depending on your city. If you can afford it, it's worth the convenience — you get a professionally lit photo with a guaranteed white background. Ask the studio for the digital soft copy in addition to prints. Many studios only hand over prints unless you specifically ask for the digital file.
Multiple SSC Exams, Same Photo?
Since all SSC exams (CGL, CHSL, GD Constable, MTS, CPO, Stenographer) use the same photo specifications, you can technically use the same photo file for all of them — provided it was taken within the last 6 months and you haven't changed your appearance significantly. This is one area where SSC is more convenient than other exam bodies.
However, don't reuse SSC photos for other exams. UPSC needs 472 × 591 pixels (larger), IBPS needs 200 × 230 pixels (much smaller), and passport photos must be square. Each requires a separate file cropped and resized from your original photo.
