How to
How to resize an image to ID card size
- 1.
Add the scan or photo. A phone photo of the card, a scan or a JPG design. Lay the card flat and shoot from straight above.
- 2.
Crop to the card edges. The frame is locked to the card shape, 8.56 x 5.4 cm, so nothing gets stretched.
- 3.
Download and print. Get a 1011 x 638 px image at 300 DPI, in the format you added (a JPG stays a JPG). Print it at 100% and it measures 8.56 cm across.
Why this size
ID card size in cm, mm, inches and pixels
Almost every plastic card in your wallet is the same size. The ISO/IEC 7810 standard calls it ID-1 and sets it at 85.60 x 53.98 mm, which everyone rounds to 85.6 x 54 mm, or 8.56 x 5.4 cm. In inches it is 3 3/8 x 2 1/8 (3.375 x 2.125, often shortened to 3.37 x 2.13). Card printers sell the same blank as CR80.
The size is shared on purpose: wallets, card holders, ATM slots and card printers are all built around it. Bank and ATM cards use it. So do national ID cards: Pakistan's smart CNIC is made to the ICAO 9303 travel document standard, whose TD1 card is exactly this size, and India's Aadhaar PVC and PAN cards follow the same shape. Smart card driving licences and most staff, student and membership cards use it too. A scan cropped to any other shape is stretched or cut once it is printed or slipped into a holder.
A print-ready card also needs enough pixels. At 300 DPI, the usual print resolution, 8.56 x 5.4 cm is 1011 x 638 pixels, and a 600 DPI card printer wants 2022 x 1276; the DPI converter sets the DPI of a file you already have. Crop your card edge to edge here and the tool saves it at 1011 x 638 px with 300 DPI written into the file, so it prints at true size.

We compare every size and rule on this page with the official sources below, and test the tool with sample photos before it goes live. Rules and platforms change, so if something here is out of date, tell us and we will correct it.
How the tool works
The tool scales your image once, from the original pixels, to the size you set at 300 DPI, and writes 300 DPI into the file so it prints at that size. Everything happens in your browser; your images are never uploaded.
