| Head, share of height | 70–80% of photo height |

What these millimetres work out to
- In a 40 × 40 mm frame a head band of 70–80% is 28–32 mm from the chin to the crown.
- Of the 40 mm of height that leaves 8–12 mm for the gap above the crown and the space below the chin together.
- At 300 dpi that is a head 331–378 pixels tall — below 331 px the file is too small to print, however good the crop is.
- Against the European 35 × 45 mm standard this frame is 1.14 times as wide, 0.89 times as tall and 1.02 times the area — a photo cut for one of the two cannot be reused for the other.
How to crop it, in three steps
- 01
Upload a photo taken face-on, in even light
- 02
The tool finds the face and aligns the frame itself — check that the head lands in 70–80%
- 03
Save the 40 × 40 mm result — print it or attach it to the application
What we fix for free, and what AI fixes
Fixed for free
- Background. Replaced with the one this document asks for: plain light background without textures or noticeable gradients.
- Head tilt. Straightened if the head leans slightly to one side.
- Frame. Exactly 40 × 40 mm, by the document’s rules.
- A light shadow on one side of the face. Gently brightened.
- File and print sheet. A file to the document’s rules and a 10 × 15 or A4 sheet to print.
What can't be fixed for free, AI correction fixes
- Hard shadows and uneven light on the face.
- A smile, raised brows or a half-open mouth. Cropping keeps the face it was given.
- Too few pixels. If the original is smaller than 472 × 472 px, enlarging it only blurs the face.
- Clothing and pose. Shoulders out of frame, body turned away from the camera.
Glare on the lenses. Take the glasses off or turn away from the light source and shoot again.
Why these photos get rejected — and how to fix each one
Chad-specific things to know
- The Embassy asks for four photographs for the passport — more than most — «biometric» and «not scanned», of 40/40 mm, and two of the 4×4 format for the laissez-passer.
- The Embassy in Berlin issues neither the passport nor the identity card: the applicant sends the file himself and, without an NNI, travels to N'Djamena to be enrolled.

Where these numbers come from
Source: Embassy of the Republic of Chad in Berlin. Last checked against the official page on 21 Oct 2026.
What the source confirms
- Embassy of Chad in Berlin, «Service passeport»: the Embassy does not issue passports or National Identity Cards; the documents to provide are the application forms for the ordinary passport and the National Identity Card (available on the page), completed and signed by the applicant; a copy of the birth certificate; copies of three National Identity Cards of witnesses, one of whom must be a close relative of the applicant; proof of profession; and «four biometric identity photographs (no scanned photographs), of 40/40 mm format».
- Same page, the note: the applicant sends the passport application himself — with the fee of EUR 160 — if he has already been enrolled and holds a National Identification Number (NNI); anyone who holds no NNI or passport but holds at least one official document proving Chadian nationality can ask the Embassy for a laissez-passer to go personally to N'Djamena and be enrolled.
- Embassy of Chad in Berlin, «Autres documents», the laissez-passer: valid for a single journey and only to Chad, issued to Chadian nationals who lost their passport or whose passport has expired and to newborns in the jurisdiction of Chadian parents going to Chad for the first time; the documents — a form completed on the spot, «Two identity photographs (4×4 format)», a flight ticket, a birth extract for newborns, a declaration of loss or police report if the passport is lost and the original of the expired passport; the processing fee is EUR 20.
