GATE is stricter than most: it constrains the aspect ratio, sets both a minimum and a maximum resolution, and — uniquely — puts a ceiling on how much of the frame your face may fill.
This is the question the specification does not answer directly, and getting it wrong changes the crop completely. It means height.
GATE publishes a grid diagram showing the face filling cells A2, A3, B2, B3, C2 and C3. That is rows A to C of A to E — 60% of the height — and columns 2 to 3 of 1 to 4, which is 50% of the width. Read as area, those six cells out of twenty come to 30%, which would contradict the 60–70% in the text. Read as height, the diagram and the text agree exactly.
We also measured GATE's four published acceptable photographs. The detected face spans 47 to 55% of the frame width in all four — landing squarely on the grid's 50% column span. That is the confirmation: the diagram and the accepted samples describe the same framing, and it is a height rule.
GATE publishes sixteen sample photographs with reasons. The twelve rejected ones fail for:
Only the first of those is something a size measurement can catch. This tool checks the framing; the rest are down to how the photograph was taken.
Same application, different file. Each has its own limits — they are not interchangeable.
JPEG or JPG between 5 KB and 600 KB, with a resolution between 200 x 260 and 530 x 690 pixels and an aspect ratio between 0.66 and 0.89. GATE describes it as a 3.5 cm by 4.5 cm passport photograph.
Height. GATE's own grid diagram shows the face filling rows A to C of A to E, which is 60% of the height, and columns 2 to 3 of 1 to 4, which is 50% of the width. Read as area that grid would be 30%, contradicting the text; read as height it agrees exactly. We also measured GATE's four published acceptable photographs and their face width lands at 47 to 55% of the frame, matching the grid's column span.
Yes, and this is unusual. GATE gives a range of 60 to 70%, not a minimum. Most examinations only set a floor. A GATE photo cropped too close to the face is rejected just as one cropped too loosely is.
Normal spectacles for vision correction are allowed, but a photograph with glare on the glasses is not acceptable. If the glare cannot be avoided, GATE says the spectacles must be removed. Sunglasses and coloured glasses are never allowed.
Head coverings are not permitted except for religious reasons, and even then the facial features from the bottom of the chin to the top of the forehead and both edges of the face must be clearly shown. Caps, hats and sunglasses are listed as unacceptable.
GATE states that photographs not adhering to the specified criteria could lead to rejection of your application, and the application fee will not be refunded.
No. The crop, the face measurement and the compression all run in your browser on your own device. Your photograph is never transmitted.
Specifications on this page are taken from the Photograph and Signature page published by IIT Guwahati for GATE 2026, and are calibrated against the sixteen sample photographs and fourteen sample signatures published on that same page. GATE 2027 is organised by IIT Madras and carries the same figures on its own Photograph and Signature page.
GATE rotates organising institutes each year and its specifications have changed between cycles, so check the brochure for the year you are applying in. We are not affiliated with the GATE organising institute.
