We have a website through a vendor that we iframe the heading over and there are both fixed and full width containers/elements on the page. The site is just 100K internal users at our company. Sorry if this question has been asked before but I couldn't find it.
I am simply looking for what is the max width I can go for a fixed page in 2015? Given we have little to no usage of this site on tablets and the main purpose of this site is analytics and research - almost everything is done on company laptops.
We are currently running a lot of other internal sites (however not as large or as used) at 1380px. Why 1380px? No idea. I know that 5-6 years ago 980px was the norm. Can I go to 1380px? Could I push it further without running into problems? What is the new fixed width max?
Edit: I see the downvote so will add more info. We have 100K in almost every country in the world. I have collected data. Most - 80-90+% - probably could support at least 1500px wide. The feedback we get from surveys is that people want as much screen filled as possible. So is it OK to make the 10-20% of the people have to scroll sometimes?
