35x45 photo size: pixels, ratio and head framing
35 × 45 mm is one of the most common portrait document-photo formats. It is 3.5 × 4.5 cm, has a 7:9 aspect ratio and still needs country-specific rules for head height, background and file size.
Quick answer
35 × 45 mm is approximately 413 × 531 pixels at 300 DPI
Set the crop to a 7:9 portrait ratio, then resize to the required pixels. Do not assume that every 35 × 45 mm application accepts the same digital file or head height.
Reference table
| Measure | 35 × 45 reference | Practical note |
|---|---|---|
| Millimeters | 35 × 45 mm | Width × height |
| Centimeters | 3.5 × 4.5 cm | Same physical size |
| Aspect ratio | 7:9 / 0.778 | Portrait canvas |
| 300 DPI | 413 × 531 px | Rounded conversion |
| 600 DPI | 827 × 1,063 px | Use only when needed |
The format is not the whole requirement
A 35 × 45 canvas can still fail because the head is too large, the eyes sit too low, the background is uneven or the file is outside the portal limits. Treat the dimensions as the starting contract.
Crop without distorting the face
Lock the 7:9 ratio before resizing. Move the crop window instead of dragging one edge independently; stretching changes facial geometry and is visible to both people and automated checks.
Common countries and document types
The format appears across European passport, visa and residence-permit workflows, as well as many applications elsewhere. Some of them add exceptions, such as a light-grey background or a digital-only upload.
Frequently asked questions
01What is 35x45 photo size in inches?
It is approximately 1.38 × 1.77 inches. For a print, use millimeters and measure the finished result rather than trusting a screen preview.
02How many pixels is 35x45 mm at 300 DPI?
Approximately 413 × 531 pixels. Some portals publish an exact or minimum pixel range that overrides this conversion.
03Is 35x45 the same as 2x2?
No. 35 × 45 mm is portrait at 7:9; 2 × 2 inches is square at 1:1.
04Can I use one 35x45 photo for every country?
Only when the destination authority accepts the same background, head band, recency and file contract. The canvas size alone is not enough.
