900×1200 px Photo

The 900x1200 pixel photo is a larger, high-resolution portrait format that prints as a 3 by 4 inch image. At 300 dpi the file measures 76.2 by 101.6 millimetres, with a finished pixel size of exactly 900 wide by 1200 tall. The extra resolution makes it suitable both for clean on-screen upload and for a sharp physical print, which is why it appears in systems that may use the portrait either way.

This guide walks through the full specification, the things that most often cause a 900x1200 photo to be rejected, and the way our service prepares a file that meets the standard. Because this is a bigger image than the small passport sizes, it shows detail clearly, which is an advantage for a sharp result but also means small flaws such as glare, blur or an uneven background are harder to hide. Building the file correctly from the start is the surest way to avoid a rejection.

What this photo is for

The 3 by 4 inch format is requested by application processes that want a larger portrait than the small passport-style sizes, sometimes because the image will be printed at a readable size as well as stored digitally. The 900x1200 pixel target keeps the picture sharp at that print size. As with other digital formats, the upload is typically validated automatically for dimensions, file type and head position, so the portrait has to be built to spec rather than cropped from a casual photo.

Exact specification

Prepare the image to these measurements. The head height should be approximately 76 millimetres, equal to between 55 and 75 percent of the total image height, measured from the chin to the crown. The background must be a clean, even white field, with no shadows and no visible join where a wall meets the floor. Hold a neutral expression with the mouth closed, both eyes open, looking directly at the camera.

• Output size: exactly 900 x 1200 pixels at 300 dpi (76.2 x 101.6 mm, 3 x 4 in)
• Head height: around 76 mm, roughly 55-75 percent of the frame
• Background: plain white, evenly lit, free of shadow
• Expression: neutral, no smile, eyes open
• Glasses: allowed when the eyes remain clearly visible without glare
• Headwear: not permitted
• File: JPG up to 4 MB

Glasses, head covering and expression

Prescription glasses may be worn in the 900x1200 format provided the lenses are clear and reflection-free and the frames do not cover any part of the eyes. Because this is a larger, more detailed image, glare on the lenses shows up readily, so adjust the lighting or your head angle to keep the eyes clean. Tinted or dark lenses are not acceptable. Head coverings such as hats, caps and hoods are not permitted, and the entire hairline and outline of the head should be visible against the white background.

Common rejection reasons

Several mistakes appear again and again. The file is not exactly 900 by 1200 pixels, so the system rejects or distorts it. The head is too large for the frame and the top of the hair is cut off, or it is too small and leaves wide empty margins. The background looks grey or carries a shadow because the photo was taken too close to a wall. Glasses reflect the light. The subject is smiling or blinking. Because the image is large, soft focus and motion blur are also more visible and can cause a refusal.

How we prepare your photo

You only need to provide a clear, front-facing portrait. Our service removes the original background, replaces it with an even white field, and scales and positions the face so the head height and eye line fall inside the 55-75 percent band. We export the portrait as a 900 by 1200 pixel JPG at 300 dpi and compress it to remain within the 4 MB limit while preserving the detail that a large image demands. The file you download already matches the dimensional and quality requirements of the format.

Print and digital

Because it is built at a true 300 dpi, the 900x1200 file is genuinely print-ready at 3 by 4 inches, so a physical copy reproduces crisply without any upscaling. At the same time it uploads cleanly to systems that store the portrait digitally. Keep the JPG and reuse it wherever a 3x4 inch or 900x1200 pixel photo is requested, and the same correct file will serve both the screen and the printer.
