We ended up with separate closets and I love it! I don't know about resale but I'm glad we don't share. His closet is approximately 6 x 11 and mine is 8 1/2 x 10 1/2.

If the difference is just in space between the 2 sides (9ft wide v 6 ft wide), I'd be temped to go with the 2 larger ones. BUT, they would both need to be slightly wider than 6 ft to be comfy, if they are 11 feet long. (6.5ft is a good minimum; 7 seems "standard" in a lot of the plans we see).

9 width gives you almost 5 feet between rows of hanging clothes, and seems like a huge waste of space to me. But, maybe not for you?

In DH's closet (which is around 6 ft. wide), he only has clothing on one side and there is plenty of room. Six foot definitely isn't wide enough to have clothes on both sides. I should have clarified that. :)

Thank you for the suggestions. We are definitely leaning towards the two closets around 6x11 each. 9x11 seems nice, but then I do think there would just be more wasted space in the center of the room.

However, it sounds like we would need to go a bit wider than 6'. Would 6 1/2 feet be adequate? That would allow for two feet of hanging space on both sides, along with a 30" walkway.

Our closet will be 9x11, same size as the last closet we had. It's a nice size if you can spare the room. It was big enough for a small bench in the middle or room to pull out the ironing board for a quick touch up.

2 without a doubt! I broke through a wall to turn a small nursery/room into our second closet. It isn't fun for a neat person to share a closet with a not-so-neat person!

We also have separate closets and I am glad we do not share. Ours are not large enough to hang clothes on both sides so we opted to put a non-straight wall in the middle of them. It is a bit hard to explain, so I am including a photo. We each have shelves and a blank wall for hooks. The shelves are in the front of the wall in my closet and on the back side of the wall in my husband's closet.
