How to Crop and Resize a Passport Photo in 2026 – Step by Step
Getting the crop right on a passport photo is more precise than most people expect. The head must be centred, the face must fill the correct proportion of the frame, and the eyes must sit at a specific height. Here is a complete guide to doing it correctly.
Key measurements (ICAO standard)
- Photo size: 35mm × 45mm (or 400×514px minimum for digital)
- Head height (chin to crown): 29–34mm (approximately 70–80% of photo height)
- Eye line: approximately 56–69% up from the bottom of the photo
- Background: plain white or light grey, no shadows
Why Correct Cropping Matters
A passport photo that is the wrong size or has the face poorly positioned will be rejected — even if the background, expression, and lighting are perfect. Passport authorities and automated photo verification systems check head size as a primary quality criterion.
The head height proportion matters because the biometric facial data extracted from the photo depends on consistent face geometry. A face that is too small in the frame provides less data for matching. A face cropped too tightly — with the top of the head cut off — fails the completeness check.
Eye position is checked by automated systems to verify that the head is upright (not tilted) and correctly sized. The ICAO standard places the eyes at 56–69% of the photo height from the bottom.
ICAO Cropping Measurements in Detail
| Measurement | Value | In pixels (400×514px) |
|---|---|---|
| Photo width | 35mm | 400px |
| Photo height | 45mm | 514px |
| Head height (chin to crown) | 29–34mm | ~330–390px |
| Eye line from bottom | 56–69% of photo height | ~288–355px from bottom |
| Top of head to top of photo | At least 2mm | ~23px minimum |
Pixel values assume the ICAO standard 400×514px digital format. Different portals may require larger minimum sizes.
Step-by-Step: iPhone Photos App
Open the photo in the iPhone Photos app and tap Edit.
Tap the crop icon (overlapping rectangles) at the bottom.
Tap the aspect ratio button and select a custom ratio. Enter 35:45 (width:height).
Drag the crop frame so the head is centred and there is space above the crown and below the chin.
Pinch to zoom so the face fills approximately 70–80% of the frame height.
Save the crop. Note: the iPhone Photos app does not verify ICAO head proportions — use this as a starting point only.
Step-by-Step: Google Photos (Android / Web)
Open the photo in Google Photos and tap Edit (the slider icon).
Tap Crop & Rotate.
Tap the aspect ratio lock and enter a custom ratio: 35:45.
Adjust the crop so the head is centred with space above and below.
Use the straighten slider to correct any slight tilt.
Tap Done and save a copy. As with the iPhone app, this gives you the right shape — but cannot verify millimetre-accurate head proportions.
Step-by-Step: Manual Method (Any Image Editor)
Create a new canvas at 413×531 pixels (35×45mm at 300 DPI). This is the print-ready size.
Paste your photo as a new layer.
Scale and position the photo so the face is centred horizontally and the face height (chin to crown) is between 290 and 378 pixels (70–90% of 531px).
Check eye line: eyes should be at approximately 56–69% of the canvas height from the bottom — around 298 to 366 pixels from the bottom edge.
Flatten the image and export as JPEG (sRGB, 80–95% quality).
Verify: open the file and check no ears are cut off, crown is not touching the top, and there is empty background above the head.
Common Cropping Mistakes
Ears cut off
Zoom out until both ears are fully visible inside the frame.
Head too small (face occupies less than 70% of photo height)
Move the crop frame closer to the face — reduce the amount of empty background.
Head too large or crown clipped
Leave at least 2mm of empty space above the top of the head.
Head positioned too high in the frame
The eyes should be at 56–69% from the bottom — not at 80% or higher.
Tilted head
Use the straighten tool. Even a 2–3 degree tilt can fail automated checks.
Wrong aspect ratio
The correct ratio is 35:45 (width:height). A square or 3:4 crop is wrong.
Important: Germany Reisepass and Personalausweis
For German passports (Reisepass) and national ID cards (Personalausweis), no self-cropped or online photo can be submitted. Germany's BSI PointID rule requires the biometric photo to be captured and submitted through a certified channel (Bürgerbüro, accredited studio, or compatible kiosk). Manual cropping is not a valid method for these documents.
For German driving licences, visa applications, and residence permits — as well as for all Swiss, Austrian, British, US, and most other users — manual or AI-assisted cropping is accepted.
Why AI Tools Beat Manual Cropping
Manual cropping is tedious and easy to get wrong. The head proportions need to be accurate to within a few millimetres, and even experienced users often misjudge the eye-line position or leave the face slightly off-centre.
AI passport photo tools — such as ID Wizard — automate the cropping process by detecting facial landmarks and applying ICAO-compliant cropping rules automatically. This means:
- Correct head height without manual measurement
- Automatic centring and straightening
- Background removal and replacement with the correct colour
- Instant verification of eye position, head size, and background
- Output as a correctly sized JPEG ready for digital submission or printing
For countries that accept online photos (Switzerland, Austria, UK, US, Australia, Canada, and many more), AI cropping tools are faster, more accurate, and more reliable than manual methods.
File Format for Digital Submission
When submitting a passport photo digitally, use these settings:
- Format: JPEG / JPG (most widely supported)
- Minimum dimensions: 400×514px (ICAO) — most portals want at least 600px wide
- Colour space: sRGB (not CMYK or Adobe RGB)
- File size: Usually 50 KB to 10 MB depending on the portal
- DPI: 300 DPI for print; digital portals typically ignore DPI metadata
Frequently Asked Questions
Can I crop a passport photo to 35×45mm on my phone?
You can apply a 35:45 aspect ratio crop on your phone, but standard camera apps do not verify ICAO head proportions. For accurate results, use a dedicated passport photo tool that checks head height and eye position automatically.
Is a 4×6cm passport photo the same as 35×45mm?
No. 4×6cm (40×60mm) is a different size used in some countries (UAE, Greece). Most of Europe and ICAO use 35×45mm.
Can I resize a passport photo to make it smaller for a digital form?
Yes, you can scale down the pixel dimensions for upload as long as you meet the portal's minimum size. Always check the minimum pixel requirements before resizing.
Does it matter if my photo is slightly off-centre?
Yes. Automated photo verification systems check centring. The face should be centred horizontally. A significantly off-centre photo may be rejected.
Always verify current requirements with the official authority before submitting your passport photo. Technical requirements vary by country and application portal.
