How many pixels are on a 8 x 10 print on the 10 inch side?

There is no set amount of pixels, as that would depend on the picture file itself, as well as camera settings, etc. The generally accepted amount of pixels to get a nice clear print is 300ppi (Pixels Per Inch). In that case, we multiply 300 by 10 (the size of the print), which gives us 3000 pixels om the 10 inch side. Using that calculation for the 8 inch side as well gives us 2400 pixels. Now if we multiply the two (3000x2400) we get 7,200,00 pixels - which means that a camera of at least 7.2 megapixels will give us a nice and sharp 8x10" print.
