The tile stickers are just under 7.75” , not 8”. The 11” measurement is close.The issue for me is two tiles stacked vertical only measure15.5”, not 16” as is referenced in the photos and the listing. My particular project really needed that extra .5” to work, otherwise I would had had to cut the tips off of a third vertical tile and used the .5” tips to fill the gap. I can tell you for certain that a .5” sticker does not stick to a wall well. I believe the project would have been a nightmare, so I’m returning them.Beware, they charge for returns. I could not find that fee acknowledged in the return policy.Haven't installed yet. I had assumed they were 11" high but want to note that they are 11"W x only 8"H. That will make a difference in how many you need for your space (will double amount I will need for my backsplash). The dept of the cut-out at the top of each tile is 3/4" so make allowances. The color is more green-blue then blue-green, which I see as a plus.We recently bought a new house and are hosting Christmas this year for 2 families!! We’ve had a lot of work done to our house so far and of course that’s pricey! One of the big changes on my list was the fireplace (see the before picture), I didn’t want to have to spend too much on it and I know with all these back order issues I may not have new tile in time, so I looked for peel and stick options and found this! I went through several different brands and options and went with the white hexagon (it’s super bright white), I thought the “grout” would be a little lighter but it’s super light gray and still coordinates with the room.I ordered the 24 pack and really only had my mind made up to do the upper front of the fireplace and not the lower part in front of it (don’t have time right now) especially since I have it covered. I had some extra pieces (5-6) to spare. I found this pretty easy to install and remove when I made a mistake, the cutting was the most difficult. I just had to use super sharp scissors.I’ll probably order another set to do the lower part after the holidays and also add caulk to the sides to make it cleaner, but overall I’m happy with this purchase. Oh and it came super fast too!!!They are very easy to cut and stick. They have stayed stuck to my wall but the adhesion isn’t uniform. I suppose that’s a good thing if you want to re-position or remove. The colors are same as picture but a bit too dark for my kitchen nook.Great customer serviceReturned as these were too "plastic" looking for me.Looks really nice. Just as in the photo.I liked the color variation, a little to shiny. Wish it looked more like a tile
