Resolution needed to print an A4 size picture
To get the right output for your image, it needs to have a certain minimum resolution. Usually, the number of pixels will depend on the required output quality.
So, at 300 ppi (pixels per inch) an A4-sized image needs to contain at least 2480 × 3508 pixels. This is the required resolution for quality offset printing for materials such as books, brochures, magazines, calendars, because they will be viewed from a short distance.
For printing of photo books, it is also the best resolution but a lower pixel count like 250 dpi is still fair enough for great-looking photographs.
At 150 ppi the image needs to be 1240 × 1754 pixels. This is the minimum resolution for newspapers or posters and other documents viewed from a fairly short distance.
While making your choice for a camera, consider using a digital camera with a decent image quality and a resolution of 8 megapixels or more as this can deliver high-quality A4 size pictures. Other digital camera with lower resolution is still fine but the result may be different the ones that are quite lower.
