"Passport size photo" is the most searched image spec in India — yet studios, forms, and websites use different numbers. Some say 35×45 mm, others 3.5×4.5 cm, others 413×531 px. They are the same aspect ratio (3.5:4.5). The confusion is only in units.
Passport Photo Size Chart — cm, mm, inches, pixels
| Standard | Size | Pixels @ 300 DPI |
|---|---|---|
| India / ISC / Most exams | 3.5 × 4.5 cm (35×45 mm) | 413 × 531 px |
| US Visa / Green Card | 2 × 2 inches (5.1 cm square) | 600 × 600 px |
| UK / Schengen (common) | 35 × 45 mm | 413 × 531 px (same as India) |
Indian Passport Photo Rules (Ministry Guidelines)
For Indian passport applications via Passport Seva, photos must be:
- Colour, matte or semi-matte finish
- White or light plain background
- Face centred, both ears visible, neutral expression
- No uniform (except religious dress worn daily)
- Recent — taken within last 6 months
Online portals (GATE, SSC, resume sites) reuse the same 3.5×4.5 cm ratio but may add KB limits — typically 20KB–200KB depending on portal.
How to Make Passport Size Photo Online Free
- Take a well-lit portrait — shoulders up, plain wall behind you.
- Open Passport Photo Size Tool.
- Select Standard 3.5×4.5 cm or US Visa 2×2 if applying abroad.
- Upload — tool crops to correct aspect ratio and compresses (under 100KB for standard).
- Download print-ready JPG or upload directly to your form.
Print at Home vs Studio
For physical forms, print on 4×6 photo paper at a shop — ask for 8–12 copies per sheet of 3.5×4.5 cm cuts. For digital-only uploads, pixel-perfect JPG from a browser tool beats a studio CD that outputs wrong DPI.
- 3.5×4.5 cm = 413×531 px at 300 DPI
- US visa needs square 600×600 px — different tool tab
- Avoid WhatsApp compression before resizing
- White background saves KB and passes biometric checks
3.5×4.5 cm or US 2×2 — one tool.
