45x45 mm Photo: the Perfect Size for your Document needs
A 45x45 mm (4.5x4.5 cm) photo is often needed when you apply for a visa, ID card, or other official documents. To avoid any delays or rejections, it's very important that your photo matches these exact requirements. We make it easy and stress-free to take a 45x45 mm photo that meets all the requirements at PhotoGov. Just send us a selfie or picture, and we'll resize, trim, and optimize it to the right size for digital or printed submission.

How to take your own Photo 45x45 mm photo
The photo rules for a job application are looser, and a separate guide describes the setup employers expect.
If you don’t want to go through the trouble and expense of locating and hiring a professional photographer to take your picture, you can simply take your own from home. So long as you follow the below instructions carefully, you can capture the perfect photo photo yourself:
1. Take a picture of yourself
Open up the PhotoGov.net photo service and take your picture. Make sure you’re not wearing any headcovers or glasses, do not wear a uniform, and keep your expression neutral. Ensure that the area is well-lit and that you are standing against a neutral background.
Watch "How to take a photo" (00:46)
2. Upload your photo to PhotoGov AI
Next, upload your image and process it through our site.
3. Receive your Passport Photo
Finally, you can download your ID photo. These images can be printed off, or you can simply use them as digital photos.
Avoid These Common Mistakes
Using a passport-size photo instead of the minimum 45x45 millimeter size
Wearing glasses or other things that block your face
Pictures that are grainy, low-resolution, or too bright
Background with patterns, shadows, or things
Smiling or tilting your head
PhotoGov automatically finds and fixes these problems as it is processing
How to take Photo 45x45 mm photos for babies and kids
When taking pictures of babies and children for photo, many of the same rules apply; for example, they must still adhere to the dress code, and the photograph must be high-quality and well-lit. With that being said, the State Department is generally more forgiving when it comes to the neutral expression requirement.
- If you are photographing a newborn:
- Spread a white sheet out over the floor.
- Place the baby down on the sheet and take their photograph against it.
For slightly older babies:
- Prop them up in a child’s chair against a white sheet.
- If they are still unable to hold up their head, prop it up for them using a hand behind the sheet. Ensure no one else is visible in the shot.
More tips for being compliant
No retouching: Don't use applications or filters that change the way your face looks
Sharpness: Make sure your picture is clear and not pixelated or blurry
Face Coverage: Your face should take up 70–80% of the height of the picture
File Size and Type: JPEG or PNG, and less than 1 MB for digital submission
Guidelines for Submission and Printing
For Physical Submission: Make sure the photo is exactly 45x45 mm and print it on high-quality matte or glossy photo paper
To submit digitally, upload your photo to the right portal. Make sure the file size and resolution are correct For US federal forms, our 2x2 photo guide sets out the 51 x 51 mm square and the digital upload specs.
