40×50 mm Photo

The 40×50 mm photo is one of the most widely requested document sizes in the world. At roughly 1.57×1.97 inches, it sits between the smaller 35×45 mm passport standard and the larger square formats, and it is accepted by a broad range of identity documents, application forms and membership cards. Because it is a generic size rather than a single country's official portrait, it is used wherever an authority or institution specifically asks for a 40 by 50 millimetre print.

Our service prepares this format to a clean, predictable standard so that your photo is ready for both printing and digital upload without guesswork.

Where this size is used

A 40×50 mm photo appears on many internal identity cards, work permits, student and library cards, visa annexes and a variety of administrative forms. Some institutions ask for it because it gives a slightly larger face area than the common 35×45 mm portrait while remaining compact enough to mount on a card. Always confirm the exact size your office requests; when they ask for 40×50 mm, this is the format you need.

Exact specification

The finished image measures 40 millimetres wide by 50 millimetres tall, which is approximately 1.57×1.97 inches. At a print resolution of 300 dpi this works out to about 472×591 pixels. The head height should be approximately 37.5 mm, which keeps the face within the accepted band of roughly 62 to 76 percent of the total frame height. The background must be plain white (#FFFFFF), evenly lit and free of shadows. The portrait is centred, with the eyes looking straight at the camera and a neutral expression.

Common rejection reasons

Most rejections come from a handful of avoidable issues. A background that is grey, cream or textured instead of true white is the leading cause. A smile, parted lips or raised eyebrows break the neutral-expression rule. Glasses are not accepted for this format, so any eyewear, even thin frames, can lead to refusal. Other frequent problems include heavy shadows on the face or behind the head, a head that is too large or too small for the 37.5 mm target, hair covering the eyes, and low-resolution files that look soft when printed.

How we prepare your photo

You upload an ordinary photo taken against any background. Our service removes the original surroundings and places you on a uniform white field, then centres the portrait and scales the head to the correct 37.5 mm height. We check the framing, lighting balance and proportions, and export a print-ready 40×50 mm file at 300 dpi as a JPG within the 2 MB limit. The result is a clean portrait that satisfies the neutral-expression, no-glasses and white-background requirements of this size.

Print vs digital

Some offices want a physical print to attach to a paper form, while others accept a digital upload. The 40×50 mm format works for both. For printing, the 300 dpi file reproduces crisply at its true physical size on photo paper. For online submission, the same JPG stays under 2 MB so it uploads quickly and meets typical file-size caps. We deliver a file you can send to a print shop or use directly in a web form, so a single preparation covers either path.

Tips for a successful submission

A few habits make acceptance much more likely. Take your original photo in soft, even daylight so the lighting falls equally across both sides of the face, which prevents the shadows that often cause refusal. Keep your shoulders square to the camera and your chin level, looking straight into the lens. Tie back or tuck away any hair that crosses the eyes or eyebrows. Remove glasses before you shoot, since they are not allowed for the 40×50 mm format and removing them later cannot fix reflections already in the image. Wearing a top that contrasts with the white background also helps the edges of your shoulders stay clean and well defined.

Whether you need the photo for a card, a permit or a form, preparing it to the 40×50 mm standard once means you can reuse it confidently wherever this size is requested.
