Print ID Card on A4 Sheet
Preparing an ID card for A4 printing means arranging the front and back images on a single A4 page so both sides can be printed together. Scankaro helps you crop, straighten, correct auto-straighten, and preview the layout before downloading a print-ready file.
Preparing ID images for printing
Add both sides
Upload or scan the front and back images of your ID card.
Crop the edges
Remove unwanted background by dragging the crop handles to the document edges.
Rotate if needed
Use rotation or auto-straighten so the document is upright.
Auto-straighten
If the photo is slightly tilted, click Auto Straighten to detect and correct the angle automatically.
Preview the layout
Generate the A4 layout and review the preview to confirm both sides are correct.
Correct orientation and aspect ratio
For the best printed result, make sure each image is rotated so the text reads correctly. Scankaro preserves the aspect ratio of your images — it fits them within the A4 page without stretching or distorting. The A4 canvas is rendered at 300 DPI (2480 x 3508 pixels) to maintain print quality.
Common printing mistakes to avoid
- Not checking the preview before printing — always verify both sides are present and correctly oriented.
- Printing at the wrong scale — ensure your printer is set to 100% or actual size, not "fit to page".
- Using low-resolution images — higher quality input produces sharper printed output.
- Forgetting to crop — extra background wastes space and makes the document smaller on the page.
- Ignoring tilt — an uncorrected tilted photo will look crooked when printed.
How Scankaro helps
Scankaro handles the layout preparation for you. After adding both images and making adjustments, click "Generate A4 Layout" to produce a single page with both sides arranged neatly. The preview shows exactly what you will get. Download as a PDF for the most print-friendly format, or as a JPG or PNG if you prefer.
