600×600 px (2×2 inch) Photo

The 600x600 pixel photo is the familiar square digital portrait, often described as a 2 by 2 inch image because at 300 dpi it measures 51 by 51 millimetres. It is one of the most widely requested upload formats for online applications that follow the United States style of square head shot. The defining rule is the pixel count: the file must be exactly 600 pixels wide and 600 pixels tall, perfectly square, with the head centred inside the frame.

This page covers the precise requirements, the rules that differ from rectangular formats, and how our service produces a square file that passes the automatic checks built into most upload pages. The square shape trips up more people than any other format, because a normal camera or phone takes rectangular pictures, and simply cropping one to a square almost never lands the head in the right place. Understanding the rules before you start makes the whole process far smoother.

Where this size is used

A 600x600 portrait is the standard digital upload for many US-style application portals and identity systems that store a square image. These systems almost always validate the file the moment you upload it, measuring the pixel dimensions, the file format and the proportion of the frame filled by the head. Because the square shape and the head-size band are both checked, a casual selfie or a cropped phone photo is usually refused. A purpose-built 600x600 file avoids that.

Exact specification

Produce the image to these measurements. The head height should be approximately 38.25 millimetres, which falls between 50 and 69 percent of the total image height, measured from the chin to the top of the head. The background must be plain white, evenly lit and free of shadow. Keep a neutral face with the mouth closed and both eyes open, looking straight ahead.

• Output size: exactly 600 x 600 pixels at 300 dpi (51 x 51 mm, 2 x 2 in)
• Head height: around 38.25 mm, roughly 50-69 percent of the frame
• Background: solid white, no shadows or texture
• Expression: neutral, no smile, eyes open
• Glasses: not allowed; remove them before the photo is taken
• Headwear: only permitted when worn daily for religious reasons, and the full face must stay visible
• File: JPG up to 2 MB

Glasses and head covering

Unlike some rectangular formats, the 600x600 standard does not allow glasses. Take them off before the picture is captured so there is no chance of glare, frame shadow or partly hidden eyes. Head coverings are only acceptable when they are worn every day for religious reasons; in that case the covering must not cast a shadow on the face and the full face from the bottom of the chin to the top of the forehead must remain clearly visible. No other hats, caps or hoods are allowed.

Common rejection reasons

The square format produces its own typical failures. The image is not actually square, having been cropped to 600x600 from a rectangle so the face looks stretched. The head fills too much of the frame and breaches the 69 percent limit, or sits too small below 50 percent. The background turns grey or shows a shadow because the photo was taken close to a wall. Glasses were left on. The person is smiling or the eyes are not fully open. Each of these is checked automatically, so each one matters.

How we prepare your photo

Send us a clear, front-facing portrait and our service builds the square file for you. We cut the subject out of the original background and place a clean white field behind them, then scale and centre the face so the head height lands inside the 50-69 percent window required for this size. The result is exported as a true 600 by 600 pixel JPG at 300 dpi, compressed under the 2 MB limit while keeping the portrait sharp and naturally toned. You receive a square image already shaped to the format.

Print and digital

The 600x600 file is a digital-first deliverable, but because it is built at 300 dpi it is also a genuine 2 by 2 inch print at native resolution. That means the same file can be sent to a photo printer if a hard copy is ever needed, with no loss of quality. For most uses you keep the JPG and upload it wherever a square 2x2 inch or 600x600 pixel portrait is requested, reusing one correct file every time.
