Is there any way we can display LWC as a separated page similar to VisualForce page? I know we can create an app than aura component which holds LWC component on VFP but we don't want to use VFP at all. We can open LWC component in a tab with full width but the top header - salesforce navigation is there. I know we can overwrite css to not display salesforce top header but this I would find as a not good practice. So the question is is there any other way to display LWC as a full width and height page without VFP?
You can use a Lightning App. Like a VFP, they are addressable via a URL:
Which you write as:
<aura:application extends="force:slds"> <c:myLwc /> </aura:application>
You can also just add the lightning__AppPage target and and make a full page app if you prefer, though it would then have some minor padding on all sides, etc.
