Do you have, and how big (height at withers and weight) are the dogs?
I'm buying Cherokee a wire crate, but I can't decide whether to get a 36" or 42". She's 21" tall and 60ish pounds. She's really not going to be crated ever, except maybe while camping (because she really hates one of the dogs we go camping with, and isn't terribly fond of the other) or otherwise traveling, so it'll basically just be a bed/den.
She has a really flimsy "pop up" crate right now, and it's 36" x 22" x 22", and really, I think it's a fine size except for height (when there's any kind of padding in it, her back touches the top..and forget her head..), so it seems like a 36" crate would be great, but I've only ever closed her in the pop up crate once, and I definitely wouldn't leave her in there for more than a few minutes, so while I know a 36" wire crate will be both wider and taller than the pop up crate, I'm unsure about the size for actually crating her... But then 42" is pretty big... She often curls up in the back of her pop-up crate, and seems rather comfy, so I'm afraid the 42" will be too big for her.. Plus pads, beds, and covers to fit a 42" are a lot pricier than to fit a 36"...
So anywho..what do you have?
