ID Photo Size Lookup
Was this tool helpful to use?
Your feedback helps us make it better
Lookup standard dimensions for common ID and passport photos, including pixels, millimeters, and usage requirements, to quickly create compliant photos.
Only source-linked Taiwan passport, US visa and Japan visa dimensions were checked in this round. All other presets are collected examples, not verified current requirements. DPI conversion does not establish digital-upload format, file-size or composition requirements. Reference
Search by document name, mm size, pixel size, or usage description
Enter width, height, and DPI for automatic conversion (300 or 350 DPI recommended)

Tips for Shooting & Usage
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This reference includes a row labeled U.S. visa with a square 51 × 51 mm size and a white background option. Use the search field to find a name or dimension, or narrow the list by category and background. The table is a quick reference to its stored entries, not an official application rules database.
Millimeters describe a physical print size; pixels describe the digital image dimensions. DPI connects the two: pixels are approximately millimeters ÷ 25.4 × DPI. For a 51 mm square at 300 DPI, that is about 602 × 602 pixels after rounding. The U.S. Department of State’s visa instructions currently specify a digital image of exactly 600 × 600 pixels, while other photo requirements also apply. That small difference illustrates why the agency’s stated pixel requirement should take precedence over a generic DPI conversion.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Search by a name or number, such as “U.S. visa,” “51,” or a pixel size already shown in the list.
Choose the category and, when useful, a background color to narrow the rows. Clear filters if a result is missing.
In the conversion area, choose millimeters to pixels or pixels to millimeters. Enter width, height, and DPI; 300 is the default.
Check the resulting millimeters, pixels, inches, and DPI. Confirm width and height orientation before copying the values.
For the listed U.S. visa row, use 51 × 51 mm as the reference entry, then compare it with the exact pixel and image rules on the official application page. The converter rounds millimeter-to-pixel results to whole pixels and pixel-to-millimeter results to one decimal place.
Use cases
See how the tool fits into real work and everyday tasks.
Search for the U.S. visa entry to see the stored physical dimensions and background option, then verify the current application instructions.
When an organization gives dimensions in millimeters and requests pixel values, enter its width, height, and specified DPI to estimate corresponding pixels.
Convert pixel dimensions back to a physical size at a chosen DPI to understand the relationship between file dimensions and print size.
Q&A
Find concise answers to common questions and confusing cases.
It lists 51 × 51 mm, which is approximately 2 × 2 inches. The State Department’s current digital visa-photo instructions specify 600 × 600 pixels; follow the current application instructions for the exact submission.
Divide the millimeter value by 25.4, multiply by the DPI, and round to a whole pixel. The page applies this calculation separately to width and height.
No. Size is only one part of the requirements. Composition, background, file properties, and the relevant application instructions matter too.
Notes
Review scope, result limitations, and important precautions before use.
The list is a static collection of common entries and can contain region-specific or variable specifications. A matching name or size does not certify a photo for an application. Requirements can differ between a U.S. visa and U.S. passport application and may change; use the current instructions for the exact document, application category, and place of submission. The conversion only relates dimensions and DPI; it does not crop or inspect an image.
