I am front-end web developer based in Europe. I just begun working remotely with team from USA. I am not a graphics designer. So far when I was cutting and embedding graphical layout into HTML and CSS I had designs made 1:1 pixel. Thanks to that I could measure dimensions right from the PSD file and apply to elements on nascent HTML template.
My new team designer sends designs that do not recreate real views on laptop, the file is not 1024x768 or 1920x[any height here] or any other known resolution. Additionaly we use CSS framework Bootstrap 3, so breakpoints are well known... but when I take a measure of container widths there is no dimension resembling Bootstrap's breakpoints.
As I am used to transfer dimensions from PSD to HTML, the template I did was not satisfying for abroad team.
My question in addition to what I stated in topic is, how should I behave? What is the way of resolving this misunderstanding?
