it's not quite the right ratio for an 8 x 10, but close. the ratio for an 8 x 10 is 0.8. mine is cropped at 0.728, which in a borderless 8 x 10 printing would leave you with a small bit of white space on one side. or, if you wanted to print it without that white space it would be 8 x 10.982 at 106% scale or 7.678 x 10.540 at 102% scale.
ok, the numbers drive some folks nuts, so, there's two ways to fix this for a true 8 x 10. you could do a slightly different crop, or, you could resize the image to 8 x 10, which would stretch the horizontal just a bit. i tried it. it's not too bad. actually, you could also change things by adding a border or frame as well.
but, here's a re-crop of the original. it basically just cuts a bit off the bottom and right side.
