The Twins Castor and Pollux — one mortal, one immortal — who loved each other so that when Castor died, Pollux begged to share his own immortality rather than be parted. Zeus set them together in the stars forever. Two bright stars still bear their names. (For those born about May 21 – June 20.)

Before a size goes on sale, the file is measured against it: pixels per inch at that size, how much of the picture a crop would lose, tone and sharpness. A size that fails is not offered, so there is nothing to choose wrong.
