More megapixels mean more detail, so you can create bigger
prints without noticing blockiness on the picture. Megapixels
aren't the be-all and end-all though ¡V the digital camera's lens
quality, sensor quality and sensor size play a big role in how
sharp and colour-accurate your pictures are". (Which? 2017)

Notice they don't bother to tell you why though, or the extent to
which these factors interact or matter.

Most consumers don't care, Which? tends to simplfy things to a
single score (used to be blobs) if you need more detail look
elsewhere.
