OK. I'll take you at your word that you don't see what I'm getting at, and I'll explain, hopefully without seeming like a total asshat.
One thing is 0.5 units long. Something else is 0.8 units long. The thing that is 0.8 long is 1.6 times as big, or 60% larger than the thing that is 0.5 units long. Now, one thing is 0.5 units long in one dimension, and 0.5 units long in the other dimension. It has an area of 0.25 square units. Something else is 0.8 units in one dimension, and 0.8 units in the other dimension, so it has an area of .64 square units. The second item is 2.56 times as big as the first item, or 156% larger.
I am trying to compare baseball to softball. My point is that the softball pitcher is far more likely to be hit in the head by the ball than the baseball pitcher, because she is much closer to the plate, and thus the number of balls hit that can actually strike her in the head is larger - because her angle of concern is larger. Heck, if she finished her motion 6' away from the plate, she'd get hit a lot, because her angle of concern would be huge. In fact, the number of balls that can strike her in the head is 2.56 times as large as the number that can strike a baseball pitcher, because he's much further away.
Look at it this way - assume a ball is hit by a batter at nose level and ignore gravity. Only the balls that hit the softball pitcher near the nose would hit the baseball pitcher anywhere in the head. A ball that hit the softball pitcher in the chin would strike the baseball pitcher in the chest, missing his head. A ball that hit the softball pitcher in the forehead would sail over the baseball pitcher's head. A ball that hit the softball pitcher's cheekbone would go wide of the baseball pitcher. Etc, etc. The softball pitcher is in a more dangerous location; she's much more likely to have a ball struck which could hit her in the head.
If you take a pistol, and try to shoot someone in the head, is it easier to shoot someone 20' away or 100' away? Your margin for error is much greater for the closer target, so the target is much easier to hit. In exactly the same way, the softball pitcher is much easier to hit than a baseball pitcher. In fact, she's 2.56 times as easy to hit, assuming the angles of concern you gave of 0.5 and 0.8.
If a softball pitcher is 2.56 times as easy to hit than a baseball pitcher, she requires more protection than a baseball pitcher. Period.
