It is in a div with the right size, I tried to hide overflow and it fitted exactly into the 1200px.

I have noticed that it happens when I choose a tiles structure that is not based in 1:1 aspect ratio pictures, but in 4:3 or 2:3. Now I’m using only square tiles, and it’s back to normal.

For the record, if I setup the tiles with no separation between them, the total width is exactly 1200px.
