The safe we had in the closet in our room was wide enough for my ipad. However, it was not very wide, so we had to be creative to also fit in 2 cell phones and 2 DS Lites. Many times we had to balance. I am not sure how big a laptop would fit, but I would think a 17 inch or less, that is not very wide. My 10 inch netbook has a big battery, so I was glad to have my ipad, as I don't think the netbook would have fit with its battery in the safe.
The safe is about chest high, and recessed in the wall. push key entry. I did not measure, but I'd say 3-4 inches wide, by about 20 inches high. The door is thick, so that takes up some of the room when you close it.
Hope this helps.
