I think the easiest way to deal with this would be to increase the size of the crown. Or add a small piece of quarter round. Certainly easier than rehanging the cabinets which would then probably not be level. The gap is so small I really had to look for it, and personally, it's not something I would worry over.

I'm with Bobbi P on this one. Moulding can definitely come to your rescue here. Cute kitchen btw!

I third the suggestion to increase the crown moulding. On another topic, I've not seen bar stools facing away from the kitchen. Is there a tv or dining room on the other side?

Thanks for the ideas, I also thought a filler piece would be a good option, but the hubby didn't agree so I will show him the suggestions. Thanks for saying it is not that noticeable but it is to me, I guess because I know it is there. As for the question about the stools facing away, they do face the living/den area and we can see the TV but we really wanted a breakfast counter and this was the best plan we came up with. One of the other things I did was to paint the wall behind the gap a color similar to the cabinets to help diminish the appearance of the gap, I think it helped a bit.

I think all sorts of house have their imperfections which stand out like a sore thumb to their owners, at least partly because the owners have seen the house "naked". But once furniture and lights and rugs and plants and accessories -- and people! -- are in, there are very few visitors if any who ever notice those flaws.

That gap shows a bit more in your photos because you haven't kept that far counter line horizontal which just accentuates it. Still, I have to agree with you now that you've pointed it out that it is a fairly substantial difference (what is the actual difference in the gap from the lowest to the highest point?) and while I think the filler piece works very well in the photos above, I'm not sure it would work in your kitchen: my eye would rather see the dark block of cupboards even and true rather than to have a slanted upper line.

Someone suggested to me the other day that a solution to my problem might be distracting the viewers' eyes elsewhere, and while my problem and yours aren't the same, seems that the same solution might work: if you draw the attention away from that upper line, no-one will ever even think to look there!

The gap is quite large, the level area is only about 1 inch from ceiling, then at the left corner it starts to incline from one inch at the corner to 3 1/ 4 at the far right. I also thought to put some grapevine or floral string of something to camoflage, it could help with the shadow that gets cast onto the ceiling which I also feel draws your eye to it.

Maybe this is a weird idea but desparate times call for desparate measures. Can you fill the gap with paintable caulk, smooth the caulk, and paint it to match the cabinets?

In planning a kitchen we take floor to ceiling measurements all over the room. When we see this much difference, we plan for the filler strip as described above and put the crown on that. You need to hold something up there to look at that though as a 2.5" difference is pretty substantial and will still be noticable.

I think whoever says the gap is small is only seeing the gap on the left side. As it goes to the right side of the picture it is sizeable. I think the filler piece and then the crown is the only way to go.

Once upon a time and long ago our company remodeled a kitchen where the ceiling was out of level by 2" plus along the cabinet wall. When the issue was discovered, we addressed it with the owners and agreed to level the ceiling and split the cost with them. Once that work was completed the kitchen could be correctly installed, and of course we learned to always check for level First!

To work this solution backwards, carefully dismantle the upper cabinets, level the ceiling, then re-install. This sounds harsh, but in all reality rectangles that are out of plumb or level will always tell the truth. Using trim details or caulking to adjust for 1/4" in 3' can be done almost invisibly by a skilled craftsman...more than that and he begins be frustrated with the person who assigned an impossible challenge.

measure from left of sink up to upper cabinet, then do same on right, it looks to me as though the 2 measurements are not the same. I would move the right upper cabinets up some.
