Salesforce: Lightning Record Page

What is the Lightning Record Page? 

Lightning Record Page is not the same as Page Layout, it is more than the Classic Page Layout.

From the above screenshot:

• Red box = lightning record page
• Blue box = page layout

Page layout (under the Detail tab) is part of a lightning record page. Page layout is required to show fields of the object until Dynamic Forms is widely available.

The "Related" tab contains related lists which are defined in the page layout.

Buttons at the upper right corner are also defined in the page layout, but this can be upgraded to Dynamic Actions which was introduced in the last few releases.

Lightning versus Classic

• Lightning Record Page only for Lightning 
• Page Layout is a heritage from Classic
