Resize Image to A4
Place a photo, scan, poster, worksheet, or graphic on an A4-proportion canvas with calculated print pixels and adjustable margins.
A4 proportions with practical margin control
Accurate A4 aspect ratio
Use 210 x 297 mm proportions in portrait or landscape orientation.
150 or 300 DPI pixels
Generate approximately 1240 x 1754 or 2480 x 3508 pixels in portrait mode.
Adjustable millimeter margins
Reserve printer-safe whitespace while fitting or cropping the source inside the usable page area.

A4 dimensions, DPI, and printer margins
A4 paper measures 210 x 297 millimeters, or about 8.27 x 11.69 inches. At 300 DPI, the common rounded raster dimensions are 2480 x 3508 pixels. At 150 DPI, they are approximately 1240 x 1754 pixels.
Most home and office printers have a non-printable edge area. Add margins unless the printer explicitly supports borderless A4. Browser image export may not embed print-density metadata, so select A4 paper and verify scaling in the print dialog.
