When making web designs and UI designs in Photoshop CC 2017, after being approved by the customer, then the website is being coded. During the coding process, website becomes available on some domain name for testing purposes and sometimes I get a report from coder or client, that all elements that are on the site looks too big, not much, but definitely needs to be made smaller.
I am trying to understand, why this happens and one of the versions is that maybe during the design process I forget to fit artboard to 100%. Text size is the main problem in most cases.
I want to know, is there some tricks to learn and know to be sure that all these web elements looks like it should be every time I design for web? Is there some mandatory specifications that I always need to keep in mind, like smallest and biggest font size for header menu, website main text etc.?
