Is 2x2 Inches OK for a Cambodia Visa Photo? US Passport Photo Size vs the 35x45 mm Spec
Short answer: yes, the 2x2 inch photo Americans know from the US passport office works for the Cambodia eVisa, because the online application reads pixels and file size, not a printed inch or millimeter measurement. Here is why the 35x45 mm number keeps coming up, and what actually matters when you upload.
Is a 2x2 inch photo OK for the Cambodia eVisa, or does it need to be 35x45 mm?
A 2x2 inch photo is fine for the Cambodia eVisa. The online application is a digital upload that reads your photo by its pixels and file size, not by a printed inch or millimeter measurement, so the US 2x2 inch (51x51 mm) format Americans already know works without modification. The 35x45 mm figure you may have seen is the older printed passport-style dimension that describes the framing — head and shoulders, face filling most of the frame — rather than a rule the uploader checks. What the system actually requires is a JPEG under 2 MB, ideally 600x600 pixels or larger and roughly square, on a plain white background, with a neutral expression and no glasses. Crop a standard US passport photo to a square and it uploads cleanly.
要点总结
- Yes, a US 2x2 inch (51x51 mm) photo is fine for the Cambodia eVisa — the online application reads your digital file by pixels and file size, not by a printed inch or millimeter card.
- The 35x45 mm figure you see quoted is the old printed-photo passport-style dimension; it describes the framing (head and shoulders, face filling the frame), not a hard pixel rule the uploader checks.
- What the validator actually enforces: a JPEG under 2 MB, ideally 600x600 pixels or larger, roughly square, on a plain white background with a neutral expression and no glasses.
- A square US passport photo crops perfectly for the upload — the framing on a 2x2 and a 35x45 portrait is nearly identical once the head fills the frame, so you do not need to re-shoot.

The short answer: yes, 2x2 is fine
If you have a US passport photo on hand — the square 2x2 inch shot the State Department asks for — you can use it for the Cambodia eVisa without re-shooting. That trips people up because half the guides online quote a 35x45 mm size and the other half say 2x2 inches, and the two numbers do not match. The reason both can be true is simple: the Cambodia eVisa is an online upload, and an online upload does not care about inches or millimeters at all. It reads your photo as a digital file, by its pixel dimensions and its file size.
So the inch-versus-millimeter debate is mostly a leftover from the era of printed passport photos pasted onto paper applications. When you submit a Cambodia eVisa, no one measures a physical card. The system checks that your image is a JPEG, under 2 MB, sharp enough to read your face, and framed like a passport photo. A US 2x2 inch photo satisfies every one of those once you crop it square, which it usually already is.
This guide explains exactly where the 35x45 mm number comes from, why your 2x2 inch photo still works, and the handful of things the upload validator genuinely does enforce so your file clears on the first try. When your photo is ready, you can apply in a few minutes. For the wider picture — cost, processing, documents — start at our Cambodia visa for United States citizens hub and work down from there.
Why you see both 2x2 inches and 35x45 mm
The two figures come from two different passport-photo traditions. The United States standardized on a 2x2 inch (51x51 mm) square photo — that is the size you get at the drugstore counter or the post office, and it is what the US passport office requires. Most of the rest of the world, including the printed-photo convention many visa guides were originally written against, uses a 35x45 mm portrait rectangle. Cambodia sits in a region where the 35x45 mm number circulated for years, so older guides repeat it.
Here is the key point Americans miss: 35x45 mm is a printed-card dimension, not a digital rule. It describes a physical photo you would have glued to a paper form. The Cambodia eVisa replaced that paper workflow with an online upload, and the upload does not measure your photo in millimeters. It measures it in pixels and megabytes. So the 35x45 mm figure is really just telling you how to frame the shot — head and shoulders, face filling most of the frame, a little space above the hair — not what file to produce.
And the framing on a US 2x2 and a 35x45 portrait is nearly identical in practice. Both want your head and the top of your shoulders filling the frame, centered, looking at the lens. The 2x2 is square and the 35x45 is slightly taller, but once your face dominates the frame the difference is trivial and the uploader is happy with a square crop. If you want the precise pixel math and the megabyte limit spelled out, our deep dive on Cambodia eVisa photo size and file format covers the exact numbers the validator reads.
常见问题解答
Is a 2x2 inch photo OK for the Cambodia eVisa?
Yes. The Cambodia eVisa is a digital upload that reads your photo by pixels and file size, not by a printed inch measurement, so the US 2x2 inch (51x51 mm) format works without modification. Crop it square, make sure it is a JPEG under 2 MB at 600x600 pixels or larger, and it uploads cleanly. The 2x2 photo also already matches the white-background, neutral-expression content rules.
Does the Cambodia visa photo have to be 35x45 mm?
No. The 35x45 mm figure is the older printed passport-style dimension that describes how the shot is framed — head and shoulders, face filling the frame — not a rule the online uploader checks. Because the eVisa is a digital upload, it measures your photo in pixels and megabytes, so a US 2x2 inch photo is just as valid as a 35x45 mm one once it is cropped and saved correctly.
What size does the Cambodia eVisa photo actually need to be?
In digital terms: a JPEG, under 2 MB, ideally 600x600 pixels or larger and roughly square, cropped to head and shoulders. Those are the numbers the upload validator reads. The "2x2 inch" or "35x45 mm" descriptions are about framing, not the file the system checks, so resolution and file size matter more than any physical dimension.
Can I reuse my US passport photo for the Cambodia eVisa?
Yes, if it is recent (within the last 6 months) and you have the digital file. Many US photo services email a 2x2 inch image at 600x600 pixels or higher, which is already in range — just confirm it is a JPEG under 2 MB and upload it. If you only have a printed card, a fresh phone shot at home is usually cleaner than scanning the print, which can pick up glare or a color cast.
Why do guides give two different photo sizes for Cambodia?
Because two passport-photo traditions overlap. The United States uses a 2x2 inch square, while the printed-photo convention many older guides were written against uses a 35x45 mm rectangle. Both describe roughly the same framing, and since the Cambodia eVisa is now an online upload that reads pixels rather than a printed card, both inch and millimeter figures are just shorthand for how to frame the shot.
Will my photo be rejected for being the wrong size?
Almost never for the inch-versus-millimeter dimension. Size-related flags come from digital-file issues instead: a HEIC file rather than a JPEG, an uncropped original over 2 MB, or a resolution below 600 pixels. Convert to JPEG, crop tightly to your head and shoulders, and check the result is at least 600 pixels per side, and the size question disappears.
