Originally home plate was a 12 inch by 12 inch square. It was rotated 45 degs. so that it fitted the playing field. The pitchers would argue that they would not get the called strike when the ball went over the corners of the plate. On March 9th 1900 the owners in the National League changed the shape of home plate to five sides in order to get rid of the corners. They figured this would eleminate the arguements on called strikes. Before changing the shape of the plate, the distance across the corners was 16.97 inches. After making the change it appears that they rounded off the distance to make the width of the plate an even 17 inches.

How do you measure the distance from the mound to home plate?

You start at the pointy end of home plate and measure 60 feet 6 inches towards second base. That is where you would place the front of the pitcher's rubber. Then from the middle of the pitcher's rubber you measure 18 inches towards home plate and mark that spot. Measure an 18 foot radius around the marked spot. That is the pitcher's mound boundary. To make sure you're correct, you would then measure from the front of the mound to the front of the pitcher's rubber. It should equal 11 feet 6 inches.
