Hi ​@DeltaUser 

To customize your layout, you have to rely by manually resize swimlanes and shapes by selecting them and dragging to your desired size.

To learn more - Set swim lanes to a consistent size in Lucidchart | Community

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards
 

Good morning ​@DeltaUser,

You can set the size of your canvas to reflect that page size as you are creating your board. Go to the menu at the top of the board and navigate to Board Settings, then Open board settings, and from that pop up menu you can deselect Infinite Canvas, and then choose the size you prefer. I did this in Lucidspark, but the steps are very similar in Lucidchart.

See my screenshot below:

Agreed and thank you.  But it appears there is no functionality that helps resize a flowchart to stay within a particular page size, as new information is added.  For example, let’s say you choose 8.5x11” and cram it full of information.  Then, you discover you need to add 2 new steps, but they push you beyond the board’s perimeter.
