iPad Pro 12.9-in (2nd Gen) Bigger than iPad Air 13-in (M2)?

I’ve had an iPad Pro 12.9-in (2nd gen) for years but it is on its way of being phased out so I wanted to upgrade. I realized the Pro was more than I needed so I was switching to an iPad Air and I saw that the newest M2 model came as a 13-in. Awesome. Purchased. But after putting them side by side, the 12.9 is significantly bigger. Like, not depth-wise…it’s longer, yet it’s technically a smaller screen size?

I don’t have a way to measure myself but when you look up the dimensions to compare the two, they’re not too far off from one another. So is the 12.9 iPad Pro seemingly larger just because of the extra back bordering around the screen?
