How to take a clean 30×40 mm (3×4 cm) photo at home
Camera & distance
Keep the camera level at eye height. Stand ~1 m from the camera to avoid wide-angle distortion, and 1–2 m from the wall to prevent shadows.
Expression & eyes
Face forward with a neutral or naturally relaxed expression. Eyes open, mouth closed, hair away from eyebrows and eyes.
Light & background
Use soft daylight from a window. A plain white or light gray background works best. Avoid strong shadows and color casts.
Common mistakes with 3×4 photos
Obstructions & accessories
No hats, sunglasses, earbuds, or heavy headbands. Religious/medical coverings are typically fine if the full face remains visible.
Shadows, glare & filters
Avoid flash hotspots, deep shadows, and beautifying filters. Keep skin tone natural and true to life.
Wrong size/position
Don’t submit a tilted, off-center head or an overly tight crop. Our AI enforces biometric head size and eye line placement for 30×40 mm.

A 30×40 mm photo (or 3×4 cm photo) is a common biometric size for IDs, school records, employment files, and in some cases visas or national documents. While exact rules can vary, the core standards are consistent: front-facing, neutral expression, plain light background, and a recent likeness.
30×40 mm basics — quick reference
- Printed size: 30×40 mm (3×4 cm) on photo paper.
- Typical pixel sizes: at 300 DPI ≈ 354×472 px; at 600 DPI ≈ 709×945 px (we export print-perfect files automatically).
- Background: plain white or light neutral; evenly lit, no patterns or textures.
- Head & eyes: head height and eye line placed within biometric “safe zones” (our crop guides enforce this).
- File format: color JPEG (sRGB) for portals; high-res printable sheet included.
Where 3×4 cm photos are often used
- ID cards & badges — school, university, workplace, library, and membership IDs.
- Applications & records — HR files, certifications, and government service accounts.
- Passports & visas (selected) — some authorities accept or request 30×40 mm; always check local instructions.
Digital vs. print — you’ll get both
- Digital JPEG: optimized color (sRGB), correct aspect ratio, and portal-friendly compression.
- Print sheet: multiple 30×40 mm photos arranged on A4/Letter with trim guides for easy cutting.
Pro tips for a studio-clean look
- Lighting: face a window; avoid overhead down-lighting that casts eye-socket shadows.
- Clothing: choose mid-tone colors that contrast the light background; skip neon and busy patterns.
- Grooming: keep hair off the eyes and eyebrows; remove sunglasses/earbuds; minimal jewelry.
- Distance from wall: stand 1–2 m from the background to reduce shadows and texture.
FAQ — 30×40 mm (3×4 cm) photo

What DPI should I print at?
Photo labs commonly use 300 DPI. We also support 600 DPI for extra crisp prints. The editor exports the correct pixel dimensions automatically.
What background color is required?
Most requests require a white or light neutral background. Our tool removes and standardizes the background for you.
