Hey guys!

Which page width are you using by default for your web page wireframes? Usually, I was using centered 1366 or 1000.
I was working on Macbook pro 2012, and there were no probs. But now I switched to modern and seemed like for this resolution 1920 is better to use. At the same time, I don’t know, what devices my customers use.

What would you recommend?
Thanks!
