Set the size of your Standard previews to match your screen size.

When you choose to render Standard previews you can choose how large the previews will be. You should do this because setting the size to match your screen size maintains a good balance between disk space the previews take up, the time they take to render, and general usability.

To configure the image preview size for Standard size previews, choose Edit > Catalog Settings (or Lightroom > Catalog Settings on the Mac) and select File Handling.

From the Standard Preview Size drop-down list, you can choose from one of four sizes; 1024, 1440, 1680 and 2048. Choose the size that matches the size of your monitor or which is a little smaller.

This setting will be applied to previews that you create on Import or which you create from inside the Library module itself.
