2x2 Picture Size: Inches, CM, MM, Pixels & Online Converter
Last Update: June 15, 2026
A 2x2 picture size means the photo is 2 inches wide and 2 inches tall. It is a square photo size commonly used for passport photos, visa photos, ID pictures, application forms, and official documents.
In simple terms:
2x2 picture size = 2 × 2 inches = 5.08 × 5.08 cm = 51 × 51 mm
If you need to make a 2x2 picture quickly, you can use an online 2x2 photo converter to resize, crop, and download your photo in the correct size.
2x2 Picture Size in Inches
The standard 2x2 picture size in inches is:
| Unit | Size |
|---|---|
| Inches | 2 × 2 inches |
| Aspect ratio | 1:1 |
| Shape | Square |
This means the width and height are exactly the same. A 2x2 picture is not rectangular. It should be a perfect square.
2x2 Picture Size in CM
The 2x2 picture size in centimeters is:
5.08 cm × 5.08 cm
Many people round this to:
5.1 cm × 5.1 cm
So if you are setting the photo size in a document editor, photo editor, or online form, you can use either 5.08 × 5.08 cm or 5.1 × 5.1 cm, depending on how precise the tool allows you to be.
2x2 Picture Size in MM
The 2x2 picture size in millimeters is:
50.8 mm × 50.8 mm
This is often rounded to:
51 mm × 51 mm
For most passport photo or ID photo requirements, 51 × 51 mm is accepted as the metric equivalent of a 2x2 inch photo.
2x2 Picture Size in Pixels
The pixel size of a 2x2 picture depends on the DPI or resolution. DPI means “dots per inch.” The higher the DPI, the more pixels the image will have.
Here is a simple 2x2 picture size pixel chart:
| DPI | 2x2 Picture Size in Pixels |
| 72 DPI | 144 × 144 pixels |
| 96 DPI | 192 × 192 pixels |
| 150 DPI | 300 × 300 pixels |
| 200 DPI | 400 × 400 pixels |
| 300 DPI | 600 × 600 pixels |
| 600 DPI | 1200 × 1200 pixels |
For most online passport photo, visa photo, and ID photo uses, 600 × 600 pixels is a common 2x2 photo size because it equals 2 × 2 inches at 300 DPI.
2x2 Picture Size for Passport Photo
A 2x2 photo is commonly used for passport applications in countries such as the United States. The photo should usually be:
- 2 inches wide
- 2 inches tall
- Square shape
- Clear and recent
- Taken against a plain background
- Centered with the face clearly visible
Passport photo rules may vary by country, so always check the official requirements before submitting your photo.
2x2 Picture Size for Visa Photo
Many visa applications also use a 2x2 inch photo size. For example, some visa photo requirements ask for a square photo with a clear face, plain background, and correct head position.
The most common 2x2 visa photo sizes are:
| Format | Size |
| Printed size | 2 × 2 inches |
| Metric size | 51 × 51 mm |
| Digital size | 600 × 600 pixels or higher |
Before uploading your visa photo, check the official visa application website for file size, background color, and pixel requirements.
How to Resize an Image to 2x2 Inches
To resize an image to 2x2 inches, you need to set both the width and height to 2 inches. If you are working with pixels, use the correct pixel size based on your DPI.
For example:
- For 300 DPI: use 600 × 600 pixels
- For 600 DPI: use 1200 × 1200 pixels
- For simple online use: use 600 × 600 pixels
If your original photo is not square, you should crop it first before resizing. Resizing a rectangular photo directly into 2x2 may stretch the face or body.
You can do this easily with our online 2X2 photo editor: 123PassportPhoto. Simply upload your photo, choose the 2x2 inch photo size, adjust the crop area, and download the resized image. The tool helps you create a properly sized 2x2 photo without manually calculating inches, centimeters, millimeters, or pixels.
