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.

How to Take a Suitable Photo for ISRO Recruitment

Do's

Don'ts

⚠️
Common mistake candidates make

Candidates often assume ISRO uses the exact same specification every year and for every post, without re-checking the current notification. ICRB notifications for different posts — Scientist/Engineer, Technical Assistant, and Technician — have been known to specify slightly different limits from one cycle to the next. Treat every new ISRO notification as its own document and verify the photo section fresh each time.

How to Resize Your Photo to ISRO / ICRB Specifications

The quickest way to prepare your photo to the typical ICRB format is to use SarkariKagaz.pro:

  1. Go to sarkarikagaz.pro and search for "ISRO" in the search box
  2. Select "ISRO Photo" from the suggestions — the tool loads the typical 35mm × 45mm, 50KB preset
  3. Upload your photo by clicking the upload area or dragging and dropping it in
  4. Use the Crop tool to adjust the framing if needed
  5. Check the Form Readiness panel — all indicators should turn green
  6. Click "Download Photo" — but always double-check the resulting file against your specific ICRB notification before submitting

The whole process takes under a minute and works entirely in your browser, so your photo is never uploaded anywhere while you resize it.

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.

Disclaimer

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.
