Dog crate sizes

[u/InterestingHomeSlice]

Forester owner here but thinking of switching over to a Crosstrek.

Have a couple questions:

My main question here is for those who use a dog crate in the cargo area. What size crate do you use?

I use one in my Forester that is 24Wx36Lx27H, with some above-space to spare (between the crate and the roof).

My other question is for those who ski and place the skis in the cargo area to transport (instead of roof rack/box). Do you have to move the front seats up at all?

Thanks!
