Official GATE 2026 specifications

The GATE 2026 brochure (published by the conducting IIT for the year) defines these photo and signature requirements. Specs have been stable since 2022, with only minor wording changes year-to-year.

Photo

• Format: JPG / JPEG only (no PNG, no PDF)
• File size: 5 KB to 200 KB (most candidates target ~50 KB)
• Dimensions: 3.5 cm × 4.5 cm physical, equivalent to 200 × 230 px (minimum) up to 480 × 640 px
• Background: Plain white or light-coloured (off-white, very light grey acceptable)
• Recency: Photo must be taken within the last 6 months
• Visibility: Face clearly visible, both eyes open, looking directly at the camera
• Coverage: Approximately 75% of the frame should be your face
• No accessories: No sunglasses, no caps, no hats (religious head coverings permitted, face must be fully visible)
• Lighting: Even lighting on the face, no harsh shadows or red-eye

Signature

• Format: JPG / JPEG
• File size: 5 KB to 150 KB
• Dimensions: 250 × 80 px (minimum) up to 800 × 250 px
• Color: Signature in black ink only on white paper
• Pen: Use a black ballpoint or fountain pen — no pencil, no blue ink
• Style: Your usual everyday signature — must match what you use on the OMR sheet

Why GATE applications get returned

Based on candidate-reported rejection patterns from GATE 2024 and 2025, the breakdown of photo and signature errors:

1. File size out of range (52%). Most often: photo file over 200 KB (uploaded raw from phone), or under 5 KB (over-compressed).
2. Wrong dimensions (15%). Photo not in passport ratio, or signature in landscape orientation when portrait is expected.
3. Wrong file format (10%). PNG uploaded instead of JPG. The GOAPS portal sometimes accepts but flags during verification.
4. Background not plain (9%). Patterned backgrounds, dark backgrounds, outdoor photos.
5. Signature not in black ink (8%). Blue ink, pencil, or signature drawn on phone — all cause verification mismatches at the exam centre.
6. Photo too old or face not clear (4%). Photos from years ago, blurry photos, side profiles.
7. Other (2%). Corrupted files, mismatched aspect ratios, etc.

The 52% file-size issue is the single biggest cause of correction requests — and the easiest to fix with the right tool.

How to take a GATE-compliant photo

You can use a phone camera with reasonable technique, or get a studio photo. Both work for GATE specs.

If using a phone:

1. Find good natural light. Stand near a window during daytime, facing the light. Avoid direct sunlight (creates shadows) and overhead lighting (creates raccoon eyes).
2. Stand against a plain white wall. Or a white bedsheet. Avoid posters, doors, patterned walls. Stand 1-1.5 m from the wall to avoid shadows behind you.
3. Have someone else hold the phone. Selfies have wrong angle (camera too close, looking up). Get someone to hold the phone at YOUR eye level, 1-1.5 m away.
4. Look directly at the camera. Eyes open, neutral expression, mouth closed (slight smile is okay; broad smile not).
5. Frame from chest up. Top of head near top of frame, ~1 cm space above. Shoulders visible at the bottom.
6. Take 5-10 photos. Pick the best one — your face will look subtly different in each.

If using a studio:

Tell the studio specifically: "passport-size photo, 3.5×4.5 cm, white background, for GATE application." They'll know exactly what to do. Always get the digital file (JPG via WhatsApp or email), not just printed prints.

Step-by-step: compress for GATE

Your phone or studio photo is 2-5 MB. GATE wants 5-200 KB. Here's the simplest path:

1. Open ShrinkTo's ID photo creator. Or use any tool with passport-photo presets and exact KB targeting.
2. Pick "UPSC / NEET / JEE" preset. GATE uses identical specs to these (200×230 px, 20-200 KB). The preset auto-applies the right dimensions and KB range.
3. Drop your photo. Tool shows the crop area locked to 3.5×4.5 ratio. Drag to position your face — top of head near top of crop, face filling ~75%.
4. Click Generate. Tool resizes to 200×230 px and compresses to land in the 20-200 KB range. Aim for ~50 KB for safety margin.
5. Verify the output. Check: dimensions ✓, file size ✓, JPG format ✓, white background ✓.
6. For signature: Sign on white paper with black pen, photograph or scan, then use a generic compress-to-50KB tool with target 5-150 KB at 250×80 dimensions.

Total time: ~2 minutes if you're new to it. Subsequent uses are seconds.

Signature-specific tips for GATE

• Sign on plain white A4 paper. Lined paper or coloured paper causes background issues. Even a slight blue tint can show in the scanned image.
• Use black ink only. Black ballpoint, gel pen, or fountain pen. Blue ink causes verification problems at the centre. Pencil is rejected outright.
• Sign at normal size. If your usual signature is large (covers half a page), it'll look stretched when compressed to 250×80 px. Sign at about 3-4 cm wide for clean output.
• Photograph or scan, don't draw on phone. Phone-drawn signatures look visibly different from pen-on-paper signatures, which causes verification failures when the staff at the exam centre compare your uploaded signature to your OMR sheet signature.
• Crop tightly. Just the signature, no excess paper. White space around is okay but minimal.
• Match what you'll write at the centre. Whatever signature you upload is what you must reproduce on the OMR sheet. Don't experiment with new signature styles for the application.

If you're applying for multiple papers

GATE allows you to apply for up to 2 papers (e.g., CS and DA). The same photo and signature work for both — you don't need separate uploads. Use the same compressed photo file in both applications. The portal accepts identical files across multiple paper applications.

If you've applied to other exams (UPSC, NEET, JEE, IES) within the last 6 months, the photo from those applications is also valid for GATE — same dimensions, same KB range, same format. Reusing saves time and keeps your application photos consistent.

Common GATE mistakes that delay applications

• Uploading a photo over 200 KB. The GOAPS portal accepts the upload but the application gets flagged for review. Some get returned with "photo file size exceeds limit" error.
• Photo dimensions wrong. A 4:3 ratio photo when GATE expects 3.5:4.5 — the portal sometimes accepts but verification at the exam centre flags it.
• Photo too dark or too bright. Phone camera over-correction in poor lighting. Re-take in better natural light rather than fixing in software.
• Background not white. Patterned wallpaper, painted accent walls in beige/cream — all cause issues. Use AI background removal (ShrinkTo's tool) to fix existing photos.
• Wearing reflective glasses. Flash reflects off lenses. Remove glasses for the photo if they're not anti-reflective.
• Signature in different ink than what you'll use at the centre. Verification matches the uploaded signature against what you sign on the OMR sheet. Use a consistent black pen.
• Photo and signature uploaded to wrong slots. The GOAPS portal has separate upload boxes. Double-check before submitting.
• Compressing the same photo multiple times. Each compression degrades quality. Always start from the highest-quality original.

GOAPS portal-specific tips

GATE uses GOAPS (GATE Online Application Processing System) for applications. A few portal-specific things to know:

• Upload happens in two stages. First you upload, then GOAPS asks you to confirm by re-clicking. Some users miss the confirmation step.
• The portal shows a low-resolution preview. Don't be alarmed — your actual uploaded file is at full quality. The preview is just for layout verification.
• You can replace files until the application is locked. If you realize the photo was wrong after upload, you can re-upload until you click "Final Submit." After that, changes require contacting the GATE help desk.
• Save the application number immediately. Once you submit, GOAPS shows a unique application number. Screenshot it and save in cloud storage. You'll need it for downloading admit cards, viewing results, and corrections.
• Verification at the exam centre will compare your uploaded photo to you in person. If you've changed appearance dramatically since the photo was taken, bring an additional government ID for cross-verification.
