My door into the house from the garage is a six panel also I think. Wasnt really thinking about the interior doors at the time.

But for the interior, I went with a two panel, with an arch over the top. Probably has a name but I dont know what it is.

I chose it over the 6 panel because I thought it might be a few less corners and places to collect dust. I do like the look also.

Here is a link that might be useful:
