Giant Squid Eyes

So I was looking at an infographic about eyes (what can I say, I find them interesting after growing up with eyes that are both unusually colored and not willing to let me see more than a few inches in front of my face) and I realized something.

I've never once in my life read or heard anything say that giant squid eyes are anything other than the size of dinner plates.

This is not a unit of measurement!

How do I know that the people who came up with this have the same size plates I do? Plates come in a variety of different sizes. Sometimes I eat off of a small plate because I don't want to use one of the giant plates. When I go out to restaurants, my plate is usually the size of whatever thing they're serving me. Is there a standard size for dinner plates? Because it doesn't seem like it.

And what if dinner plates change size over time, like how when you visit buildings from hundreds of years ago all the doorways are small because everybody was shorter back then? What if people keep getting bigger and we start eating off of bigger plates? Or what if we get so diet-conscious that we make all dinner plates small so that we'll eat less? People will have a very inaccurate view of how big giant squid eyes are.

So I looked it up, and the largest one measured was 27 centimeters (10.63 inches) across.

You're welcome.
