Thanks to this promotional image for the upcoming Mario Tennis Aces, an intrepid fan figured out how big Luigi’s dick is. Let’s use their math to figure out the sizes of other Mario objects and characters.

Let’s not beat around the bush here. In this promotional picture for Mario Tennis Aces, you can see the outline of something in his pants that is more than just Ken-doll smoothness. Assuming it’s not a 1-up mushroom that he stashed away for later, that is presumably Luigi’s penis.

Twitter user Mithrilbowtie did some quick math and figured out that Luigi’s penis is about 3.7 inches flaccid. Here’s the formula behind this calculation: tennis rackets range from 27 to 29 inches long, so let’s say for the sake of simplification that everyone is using a 28-inch racket, which is about 300 pixels in this image. If Luigi’s bulge is about 40 pixels long, then that would measure out to be 3.7 inches. Math!

It’s really great that we’ve all been on this journey together, and honestly, I’m so happy for Luigi that he has a dick. But we’re also presented with a wonderful opportunity here: we can use this math to measure everything else in Mario Tennis Aces. Have you ever wondered how tall Peach is? She’s 3 feet, 3 inches.

How about Toad? He’s tiny! He’s 29.2 inches tall, only slightly longer than his tennis racket.
