Hide box size?

[Fossil]

Howdy

I'm changing up my northern blue tongue's tank and ordered an 10x8" hide box, but I don't know if I should order a larger size. Are skinks similar to ball pythons where they enjoy 'snug' spaces? if so I could just cut a larger entrance hole in the box I currently have, but if they would prefer a larger space, I have no problem returning this hide and ordering the large size, which is 13x9".

Here is him sitting in the upsidedown hide box.
He is currently 2 years old and 21" long so I don't expect him to get too much larger than this.

I use 13 x 9's for all of mine. Some of my large northerns seem even too big for those but they manage to get in there, and seem to like the close quarters.

Thanks for your input. I was leaning towards the 13x9 but I don't have enough experience with blueys to know if that is a better size or not. Mine seems somewhat small for his age but I do feel better knowing if he grows a few inches he will still have the extra room when I get the larger size.

I already have a fairly large hubba hut for my skink, and was more so looking for a box to make into a new humid hide. However, I'll be sure to keep that size in mind if he outgrows his current one, thank you for the recommendation.
