What is an 11x11 pixel eyedropper in Photoshop?

Question

Adobe Photoshop

Probably a bit of a stupid question, but still. What is 11x11 pixels or 5x5 in an eyedropper?
5 pixels in diameter? Or 5 times 5? And is it possible to see the area from which the sample is taken?

Answer 1

Takes an area of ​​11x11 pixels and chooses the average value from them.
The area is square. And the eyedropper cursor cannot be selected according to the shape of the area, unless, of course, Adobe has added such an option in recent versions.
