How to Resize Passport Size Photo Online
(2x2, 3.5x4.5 cm) - 2026 Guide
Let me tell you about the passport photo that almost ruined a trip
My friend was flying to Canada. Passport ready, visa approved, bags packed. At the airport, they rejected his passport photo. "Wrong dimensions" they said. Not 2x2 inches. Not even close. He had to rush to find a photo booth, pay triple, stress through security. All because he didn't know how to resize a photo correctly. I've helped dozens of people avoid this exact situation. Here's how.
Why Getting the Exact Dimensions Actually Matters
This Isn't Just About Cropping
Passport photos have exact requirements because they get scanned, measured, and verified by automated systems. If your photo is 51x51mm instead of 50x70mm for Canada, the system flags it. If your head isn't between 29-34mm tall in the frame, it gets rejected. These aren't guidelines - they're strict rules.
Real example: A client's UK visa application was delayed 3 weeks because her photo was 36x46mm instead of 35x45mm. One millimeter difference. That's how precise you need to be.
It's Not Just About Inches vs Centimeters
USA uses inches (2x2). India uses millimeters (35x35). UK uses millimeters but different proportions (35x45). Canada uses completely different sizes (50x70). Australia matches UK but has different background requirements.
Head Size Matters Too
Your face needs to be a specific size within the photo. Typically 70-80% of the photo height. Too small and you look distant. Too large and your features get cut off. This is where most DIY photos fail - people focus on overall dimensions but forget about head size.
Quick check: From chin to top of head should be about 1 to 1-3/8 inches (25 to 35mm) in a 2x2 inch photo.
Exact Photo Sizes by Country (2026 Requirements)
Country | Dimensions | Background | Key Requirements |
|---|---|---|---|
USA | 2×2 inches (51×51 mm) | White or off-white | Head 1 to 1-3/8 inches tall, neutral expression |
India | 35×35 mm (3.5×3.5 cm) | Light colored | Recent (last 6 months), front view, plain background |
UK | 35×45 mm (3.5×4.5 cm) | Light grey or cream | No shadows, face clearly visible, high contrast |
Canada | 50×70 mm (5×7 cm) | Plain white | Neutral expression, shoulders squared, no glare |
Australia | 35×45 mm (3.5×4.5 cm) | Light grey | Taken last 6 months, quality print, no alterations |
Schengen (Europe) | 35×45 mm (3.5×4.5 cm) | Light grey | Recent, sharp focus, face 70-80% of height |
Important: These are the 2026 requirements. They do change occasionally. Always double-check on your government's official website before submitting. But these have been stable for years, so they're a reliable starting point.
How to Actually Resize Your Photo (The Right Way)
Step 1: Take or Choose a Good Photo
Stand against a plain, light-colored wall. Good natural light from front (not behind you). Neutral expression, eyes open and visible. No hats, glasses (unless medically required), or headphones. Have someone else take it - not a selfie.
Pro tip: Take multiple photos. Different angles, slightly different expressions. You'll have options to choose from.
Step 2: Upload to an Online Passport Photo Tool
Use a tool specifically designed for passport photos. Not general photo editors. Passport tools enforce the exact rules - dimensions, head size, background color, DPI requirements.
Step 3: Select Your Country and Purpose
Choose the exact country and document type. USA Passport? India Visa? UK Residence Permit? Canada PR? Each has slightly different requirements. Good tools have these pre-configured so you don't have to remember millimeter conversions.
Step 4: Adjust and Verify
The tool will show guidelines. Position your face so it fits within the markers. Check that head size is correct (chin to top of head within the marked area). Verify background is plain and light-colored. Remove any shadows if needed.
Check these: No shadows behind ears, hair not covering face, eyes clearly visible, neutral expression, shoulders even.
Step 5: Download and Print
Choose how many copies you need. For just passport application, 2-4 photos. For multiple documents, 8-16. Download as PDF or image. Print on photo-quality paper at home or at a print shop. Make sure printer settings are correct (no scaling, actual size).

DPI, Print Quality, and Other Technical Details
What DPI Actually Means for Your Photo
150 DPI
Basic quality
Okay for digital submission, might look pixelated when printed
300 DPI
Recommended standard
Sharp for printing, professional quality, accepted everywhere
600 DPI
Professional grade
Extremely sharp, large file size, overkill for most uses
In practice: Use 300 DPI. It's the sweet spot between quality and file size. Your photo will look crisp when printed, and it meets all official requirements. Only use 600 DPI if you're submitting for a professional license or similar where extreme quality matters.
