50×50 mm Square Photo — Print Pixels vs Portal Pixels

How Many Pixels Is a 50×50 mm Photo? (591×591 at 300 DPI)

The 300 DPI print equivalent of a 50×50 mm square photo is **591×591 pixels**: 50 ÷ 25.4 × 300 = 590.55, rounded to the nearest pixel. At 600 DPI the same square becomes 1181×1181 pixels. Both values describe a file destined for **paper** only; for the complete list of sizes, the table of all document photo sizes keeps them in one place.

The square format does not appear in Turkey's official documents: ID cards, driving licences and passports require the 50×60 mm rectangle, while the Schengen and ICAO family uses 35×45 mm. In our catalogue the 5×5 cm square is tied to two applications — the Umrah and Hajj visa and the South Korea K-ETA — and both are fully digital portals that never take a paper photo. That is why the real question on this page is not "how many millimetres" but "which portal asks for how many pixels".

Why Does the Portal Pixel Box Not Match the 300 DPI Calculation?

DPI is a print concept: it is the bridge that converts millimetres into pixels. A portal that accepts a digital upload never sees millimetres; it validates only the pixel box and the byte size of the file. That is why a 591×591 pixel file built for 300 DPI is rejected — not because it is low quality, but because it falls outside the requested box. The reverse also holds: print a 200×200 pixel portal file at 5×5 cm and the resolution drops to 200 ÷ (50 ÷ 25.4) ≈ 102 DPI, which softens the print visibly.

From this follows a one-way rule: going down from high pixels is safe, going up from low pixels is not. The correct flow is to shoot at the highest resolution available and derive a separate file per target — 700×700 for the K-ETA, 200×200 for the Umrah/Hajj upload, 600×600 and 240 KB for the Green Card, a square JPEG in the 10-300 KB band for the India e-visa. Because portal limits can change with a notice, check the current value on the upload screen for every application; what does not change is that all of them derive from the same source square.

Which Applications Ask for the Same 5×5 cm Square?

Assuming that identical sizes mean identical rules is the most expensive mistake here. Saudi Arabia's Umrah and Hajj application enforces dress and face-visibility conditions at system level alongside the square photo; the South Korea K-ETA does not care about clothing but is strict about the file format and rejects any extension other than JPG on the upload screen. Both are square, both want a white background, both want a photo from the last six months — yet their rejection causes come from completely different places.

The other members of the square family are not interchangeable either: the US visa wants 51×51 mm (2×2 in), the Japan visa 45×45 mm, and the India e-visa again a 51×51 mm square. Differences of one to six millimetres look irrelevant in print, but the portals' fixed pixel boxes and automated face checks magnify them: even with a correct square ratio, face coverage can land outside the accepted band. For the full country-by-country breakdown see the visa photo sizes by country list.

How Is a Square Crop Built Differently from a Rectangle?

In a square frame the head-height band cannot be copied from rectangular sizes. Saudi Arabia's official eVisa photo specifications define the face area as a percentage: chin to crown must cover **70-80%** of the square. In a square 50 mm tall that works out to roughly 35-40 mm from chin to crown — a noticeably larger head than the 32-36 mm band of 35×45 mm. In a square format the face simply occupies more of the frame than in a rectangle.

This is why square-cropping the 35×45 photo you already own does not work: trim the sides and the head is too small for the frame, trim the top and the crown disappears — in both cases the automated check flags the face coverage. The international ICAO Doc 9303 defines the rectangular carrier for travel documents; square requirements originate at portal level and bring their own ratio with them. The right approach is to frame the square as a square from the start — shoulder line visible, head centred, a thin margin above.

When Do You Actually Need a 50×50 mm Print?

Because both portals are digital, most applications need no print at all. A physical copy comes up in three situations: spare copies an agency or group leader wants for its own file, paper applications running through a consulate, and personal archive. In those three cases 50×50 mm is the printed carrier of the digital square; it moves the same crop onto paper without changing the size. Inside Turkey, however, a square photo has no counterpart; ID card, driving licence and passport applications all require the rectangular biometric.

On a 10×15 photo sheet the square lays out differently from rectangular sizes; once cutting tolerance is taken into account, the number of photos per sheet is shown on the order screen. The flow starts with a single shot: upload the photo, read the biometric report line by line for background, expression, sharpness and face fill, then download the derivative for your target. A photo taken within the last six months is a shared condition on both portals — which is why one correctly framed square covers every square application in the same period.
