35×40 mm Photo

A 35×40 mm photograph is a compact, almost square-leaning portrait format requested for certain identity cards, permits and local document applications. Its modest height means the head sits comfortably without a large margin, so getting the proportions right is the key to a clean result.

Below you will find the precise rules for the 35×40 mm size, the situations where it is asked for, and the steps our studio takes to produce a compliant file for both print and online use.

When you need a 35×40 mm photo

The 35×40 mm size appears on application checklists for a range of identity and permit documents across several countries. Because it is a more compact format than the widespread 35×45 mm, it is usually specified by name on the form or portal you are using. The safest approach is simple: produce the exact size your institution prints in its instructions, and if that figure is 35×40 mm, this is the right page for you.

The exact specification

The image measures 35 mm wide and 40 mm tall, which is close to 1.38 by 1.57 inches. We export at 300 dpi for a sharp print. Head height should be about 30 mm from chin to crown, filling roughly 65 to 78 percent of the frame so the face is dominant without being cropped.

• Size: 35×40 mm (about 1.38×1.57 in) at 300 dpi.
• Head: around 30 mm tall, 65–78 percent of the frame.
• Background: flat, even white (#FFFFFF), no shadows or gradients.
• Face: neutral expression, lips together, no smile, both eyes open.
• Glasses: not permitted; take the photo without them.
• Headwear: only plain coverings worn daily for religious reasons, with the whole face uncovered.
• Output: JPG file under 2 MB.

Why photos in this format get rejected

The compact height of this format makes head sizing the most common stumbling block: a head that is too tall gets clipped at the crown, while one that is too small leaves an unbalanced gap. Other frequent problems are a background that is not truly white, soft shadows behind the shoulders, a faint smile, and the eyes being partly hidden by glasses or stray hair. Each of these is checked and corrected during preparation.

Our preparation process

Start with a sharply focused photo taken in diffuse, shadow-free light, facing the camera straight on. We align your head, position the face within the frame, and adjust the head height to the 30 mm target for this size. The background is rebuilt as an even white field, any shadows are cleared, and we verify a calm expression with open eyes and a closed mouth. Colours and skin tones are balanced naturally so the portrait looks authentic rather than retouched. Finally, the file is measured against the dimensional rules to confirm it complies.

Print-ready and digital files

You receive a digital JPG at exactly 35×40 mm, 300 dpi, and under the 2 MB size limit, ready for online submission. We also include a print sheet laid out at true physical size with cut lines, so you can order prints at a photo counter or print at home on standard 10×15 cm paper and trim to size. The print and the upload use the same approved image, keeping you consistent across both channels.

Final checklist

Choose clothing that stands apart from the white background, keep hair away from your eyes and the outline of your face, and look directly into the lens with a relaxed, neutral expression. If your specific application adds any extra wording, follow it exactly as written. With the 35×40 mm dimensions, 30 mm head height, white background, neutral look and 2 MB JPG limit all satisfied, your photograph is ready to submit with confidence.
