ISRO / ICRB Photo Specifications 2026
The Indian Space Research Organisation (ISRO) recruits for Scientist/Engineer, Technical Assistant, Technician, and several other posts through the ISRO Centralised Recruitment Board (ICRB), which coordinates hiring across ISRO's various centres. Unlike SSC or IBPS, which run every candidate through one uniform online portal year after year, ICRB notifications are issued separately for different posts and centres — which means the exact photo and signature requirements have, in practice, shown some variation between notifications.
Because of this, treat the numbers below as the typical ICRB requirement rather than a universal rule that applies unchanged to every ISRO recruitment ever published. Always open your specific notification PDF and confirm the photo section before you upload anything.
| Parameter | Typical Value |
|---|---|
| Photograph Type | Passport size, recent |
| Dimensions | 35mm × 45mm (width × height) |
| File Format | JPEG / JPG only |
| Maximum File Size | 50 KB |
| Background | Plain white |
| Photo Age | Recent (taken within 3 months) |
ISRO / ICRB Signature Specifications 2026
Not every ISRO/ICRB notification requires a separate signature upload — some application forms only ask for a photograph. Where a signature field is present, it typically follows this format:
| Parameter | Typical Value |
|---|---|
| Dimensions | 40mm × 20mm (width × height) |
| File Format | JPEG / JPG only |
| Maximum File Size | 20 KB |
| Background | Plain white paper |
Note: Not every ISRO/ICRB notification requires a separate signature file — check whether your specific post's application form has a signature upload field before assuming you need one.

Unlike SSC or RRB, which run one standardised, high-volume exam every cycle, ISRO recruits through its own Centralised Recruitment Board (ICRB) — a much lower-volume, more specialised process for scientist/engineer and technical roles. Because ICRB notifications are published separately for different posts and centres rather than as one recurring annual exam, the photo requirement you see can be tied to that specific advertisement rather than a single fixed standard that applies every year.
Do's
- Always open the specific advertisement you're applying under and check its photo section — don't assume it matches a previous ICRB cycle or a different post's requirements
- Take the photo against a plain white background
- Face the camera directly with your full face clearly visible
- Wear formal or semi-formal clothing appropriate for a government application
- Use even lighting to avoid shadows on your face
- Keep the source photo sharp and in focus
Don'ts
- Do not assume this year's advertisement uses the same photo specification as the last ICRB notification you saw, even for a similar post
- Do not wear sunglasses, tinted glasses, or headgear (barring religious exceptions)
- Do not use a photo older than 3 months
- Do not apply heavy filters or beautification edits
- Do not skip re-reading the notification just because you've applied to ISRO before — each advertisement can carry its own requirements
Because ISRO recruits through ICRB on a per-advertisement basis rather than one standardised recurring exam, candidates who assume "ISRO always uses 35mm × 45mm, 50KB" without checking can be caught out when a specific post's notification specifies something different. The numbers in this guide are typical values seen across ICRB recruitment, not a guarantee — always confirm against the photo section of the exact advertisement you're applying to before uploading anything.
How to Resize Your Photo to ISRO / ICRB Specifications
Open the resizer with the typical ICRB specifications already pre-loaded — upload your photo, crop it if needed, and download once the Form Readiness panel turns green. Because ICRB requirements can vary by advertisement, always cross-check the result against your specific notification before submitting. For a full walkthrough of the tool, see our step-by-step resizing guide.
What Pixel Dimensions Should the ISRO Photo Be?
ICRB notifications that use the 35mm × 45mm format specify dimensions in millimetres, but upload tools work in pixels. The equivalent pixel dimensions depend on the resolution (DPI) used:
| Resolution | Pixel Width | Pixel Height |
|---|---|---|
| 96 DPI (standard screen) | 132 px | 170 px |
| 150 DPI (medium print) | 207 px | 266 px |
| 300 DPI (high quality print) | 413 px | 531 px |
Our tool uses 96 DPI by default, which is standard for online form uploads. If your specific ICRB notification asks for a different DPI or a different physical size altogether, follow that notification instead.
ISRO Recruitment 2026 — Other Important Notes
- Different ICRB centres and posts (Scientist/Engineer, Technical Assistant, Technician) run separate application windows, each with its own advertisement — don't carry assumptions from one post's notification over to another
- Keep printed copies of the identical photo ready for any written test or interview call
- Save your resized photo in a clearly labelled folder before starting the online form
- If in doubt about any requirement, treat the official notification PDF for your specific advertisement as the final word over any third-party guide, including this one
ISRO/ICRB photo and signature specifications can vary by post and by year, and are not as uniformly standardised as some other central recruitment exams. Always cross-check the exact current notification on isro.gov.in before applying — do not rely solely on this guide's typical values.

ISRO फोटो साइज़ — हिंदी में जानकारी
बहुत से उम्मीदवार पूछते हैं — ISRO भर्ती के लिए फोटो का साइज़ कितना होना चाहिए? अधिकतर ICRB (ISRO Centralised Recruitment Board) नोटिफिकेशन में फोटो 35mm × 45mm साइज़ की, JPEG फॉर्मेट में, अधिकतम 50KB मांगी जाती है, और बैकग्राउंड सफ़ेद होना चाहिए। लेकिन ध्यान रहे — यह एक टिपिकल वैल्यू है, हर पद और साल के लिए यह अलग हो सकती है, इसलिए अपनी विशेष नोटिफिकेशन ज़रूर जांचें।
