Passport Photo Dimensions in CM, Pixels and KB for India

The Common Size: 3.5 × 4.5 cm

In India, the most common passport size photo is 3.5 × 4.5 cm (35 × 45 mm). It is the standard size for most printed photos on application forms. Some documents use a square 2 × 2 inch photo or a stamp size of about 2 × 2.5 cm, so always check what your form asks for.

Converting CM to Pixels

Pixels depend on the print resolution, measured in dots per inch (DPI). At 300 DPI - the usual quality for photo printing - a 3.5 × 4.5 cm photo is 413 × 531 pixels. At 200 DPI it is about 276 × 354 pixels. The Image Resizer does this conversion for you: choose cm, pick the DPI, and it shows the exact pixel size.

What About KB?

The KB size is the file size, not the picture size. Online forms often say something like photo between 20 KB and 50 KB. A 413 × 531 pixel photo is usually around 20-60 KB as a good-quality JPG, so it often fits without any change. If the form sets a limit, tick Compress to a file size and enter it; the tool keeps the best quality that fits.

How to Make a Passport Photo at Home

• Take the Photo :

  Plain light background, even daylight, face and shoulders visible.

• Choose the Preset :

  Select Passport size photo - 3.5 × 4.5 cm in the Image Resizer.

• Centre Your Face :

  Use the crop sliders so your face is in the middle.

• Download :

  Save the JPG; the correct DPI is stored in the file for printing.

Printing Several Photos

Photo labs and home printers can print the downloaded file at its real size, because the 300 DPI setting is saved inside the JPG. To print several copies on one sheet, place the photo multiple times in any photo layout app, or ask your local photo shop to print it at 3.5 × 4.5 cm. Glossy photo paper gives the best result.

Photo Rules to Remember

Most forms ask for a recent colour photo with a plain light background, the face clearly visible, eyes open, and no caps or dark glasses (religious headwear is usually allowed). The face should cover a large part of the photo. Read the specific instructions in your form, because some ask for a white background or a particular face size.

Digital vs Printed Photos

A printed photo needs the right physical size (cm) and a good DPI. A digital photo for an online form needs the right pixel size and KB. The same original photo can give both: make a 3.5 × 4.5 cm version at 300 DPI for printing, and a smaller pixel version with a KB limit for uploading.

Your Privacy

Photos of your face are personal. The Image Resizer works in your browser and never uploads your photo, so it stays on your own device.

Conclusion

Understanding passport photo dimensions in CM, pixels and KB makes any form easier: 3.5 × 4.5 cm is the common print size, 413 × 531 pixels at 300 DPI, and the KB limit is set separately. Use the free image resizer to create a correct passport photo size in cm or pixels in seconds, and check each form's passport size photo dimensions before you apply.

To sum up the passport photo sizes explained in this guide: the print size is set in centimetres, the pixel size depends on the DPI, and the KB limit only matters for online uploads. Keep one high-quality original of your photo, and create each version you need from it - a print version at 3.5 × 4.5 cm and 300 DPI, and a smaller upload version that meets the KB limit of your form. Label the files clearly, such as passport-print.jpg and passport-upload.jpg, so you always pick the right one. Updating your photo every year or two also keeps it recent enough for most forms, which usually ask for a photo taken within the last few months.
