Standard Photo Size Chart India: 2R, 3R, 4R, 5R, 6R, 8R, 10R & Passport Sizes

Whether you are printing family memories for a photo album, framing portraits for your living room, ordering photo prints at a local cyber cafe, or preparing official documents for Indian passports, driving licences, and government examinations, navigating the terminology of “4R”, “5R”, “Stamp Size”, “Passport Size”, and “A4 Sheets” can be perplexing.

In the commercial photographic industry across India, traditional photo labs, digital minilabs, and paper manufacturers utilize the international “R” series numbering system alongside standardized biometric dimensions. Understanding these dimensions down to the exact millimeter and pixel prevents unwanted cropping, blurry prints, and wasted photo paper.

In this comprehensive guide, we provide a complete reference chart of all standard photograph sizes used in India—including physical measurements in centimeters, millimeters, inches, studio print pixels at 300 DPI, and practical advice on how to print multiple passport photos on a single sheet to save money.

2. What Does the “R” System in Photo Printing Mean?

The letter “R” stands for “Regular” (or “Rectangular”), representing standard imperial-based photo paper aspect ratios:

The numeric value preceding the “R” indicates the shorter edge of the photograph in inches.
For example, in a 4R photograph:
- The shorter edge is 4 inches.
- Following the standard $2:3$ camera ratio, the longer edge is calculated as $4 \times 1.5 = \mathbf{6\text{ inches}}$.
- Hence, a 4R photograph is exactly $4 \times 6\text{ inches}$ ($10.16 \times 15.24\text{ cm}$).
Similarly, for 5R:
- The shorter edge is 5 inches.
- The longer edge is 7 inches ($5 \times 7\text{ inches}$ or $12.7 \times 17.78\text{ cm}$).
For 8R:
- The shorter edge is 8 inches, with a longer edge of 10 inches ($8 \times 10\text{ inches}$).

Because modern smartphones capture images in either $4:3$ or $16:9$, printing directly to 4R ($2:3$) without pre-cropping can result in heads or feet being cropped off. Always pre-crop your photos using our Ratio Calculator & Sizer before sending files to a printer.

3. Stamp Size vs. Passport Size vs. Visa Size: Key Differences

In India, identity photographs are broadly categorized into three distinct size tiers:

graph LR
    A[Identity Photo Sizes in India] --> B[Stamp Size: 2.0x2.5 cm]
    A --> C[Passport Size: 3.5x4.5 cm]
    A --> D[US Visa / OCI: 5.1x5.1 cm]
    B -->|Smallest| E[Bus pass, School ID]
    C -->|National Standard| F[Passport, Aadhaar, Driving Licence]
    D -->|Square Format| G[US Embassy, OCI Card]

1. Stamp Size Photo ($20 \times 25\text{ mm}$ / $2.0 \times 2.5\text{ cm}$)

Aspect Ratio: $4 : 5$ (0.80).
Pixel Dimensions (300 DPI): $240 \times 300\text{ pixels}$.
Usage: Traditionally used for primary school identity cards, state transport student bus concession passes, library cards, and internal college examination records. It is significantly smaller than a standard passport photo.

2. Passport Size Photo ($35 \times 45\text{ mm}$ / $3.5 \times 4.5\text{ cm}$)

Aspect Ratio: $7 : 9$ (0.778).
Pixel Dimensions (300 DPI): $413 \times 531\text{ pixels}$.
Usage: The mandatory official standard for Indian Passports (Passport Seva Kendra), Aadhaar Card (UIDAI), Parivahan Sarathi Driving Licences, Voter Identity Cards (ECI), and competitive exams (SSC, UPSC, Banking). The face must occupy 70% to 80% of the picture height.

3. Visa / OCI Size Photo ($51 \times 51\text{ mm}$ / $2 \times 2\text{ inches}$)

Aspect Ratio: $1 : 1$ (Square).
Pixel Dimensions (300 DPI): $600 \times 600\text{ pixels}$.
Usage: Strictly required for United States Non-Immigrant (DS-160) and Immigrant Visas, Overseas Citizen of India (OCI) cards, and select foreign embassy visas. Learn more in our 2×2 Inch Photo Guide.

4. The Studio Secret: How to Print 8 Passport Photos for ₹5

Commercial photo studios in India typically charge between ₹100 and ₹200 for 6 to 8 printed passport photographs. However, cyber cafes, photographers, and savvy applicants use a simple, 100% legal technique that cuts printing costs by over 90%:

The Principle: Professional photo labs do not print single $35 \times 45\text{ mm}$ photos. They load rolls of 4R ($4\times6\text{ inch}$) glossy photo paper into their digital minilab printers.
Sheet Tiling: A single 4R ($4\times6\text{ inch}$) canvas has sufficient area ($1200 \times 1800\text{ pixels}$) to tile 6 to 8 full-resolution 300 DPI passport photos arranged in a $2 \times 3$ or $2 \times 4$ grid, leaving ample white margins and dashed cutting lines.
Printing Cost: The commercial cost to print a single 4R photo sheet at any photo studio, colour xerox shop, or quick-print lab in India is merely ₹5 to ₹10.
How You Can Do It:
- Go to our free A4 & 4×6” Print Sheet Maker.
- Upload your prepared photo.
- Select the “6 Photos (4×6” Paper)“ or “8 Photos (4×6” Paper)“ layout.
- Download the high-resolution JPEG file to your phone or USB drive.
- Visit any nearby studio or Xerox shop and ask for a “4x6 inch glossy photo print”.
- Use scissors or a paper trimmer to cut along the dashed guide lines!

5. Printing on A4 Standard Paper for Bulk Requirements

If you run a school, cyber cafe, coaching center, or need photos for the entire family:

A standard A4 Sheet ($210 \times 297\text{ mm}$) can comfortably fit 12, 16, 24, or 32 passport photos.
You can print on an inkjet printer using 180 GSM to 240 GSM glossy or matte photo paper.
Ensure your printer settings are configured to “100% Scale” (Do NOT check “Fit to Printable Area”) to preserve exact physical millimeters.
