How many pixels do digital camera users need?

There is a saying that 3 million is enough, 7 million is easy to use, and100000 is special. In fact, the pixel is the size of the photo.

As a family, we usually browse on a computer or an electronic photo album, and the developed photos are not very big. 6-inch D is more common, and it is enough to enlarge a good photo to 16 inch. Here are some sizes for reference.

3 million copies of 3R and 4R photos are enough;

It costs about 5 million to print A4 format photos;

8 million pixels is enough to print or spray a photo larger than A3 (calendar size) format.

At present, digital cameras with a pixel size of12 million are very popular in the market. Just do what you can according to your own economic conditions.
