Hi Severine thanks for posting! You can reduce the width of a swimlane by hovering over the side of the swimlane until your cursor turns into a double sided arrow then click and drag to change the width. Hope this helps!

Does this also automatically adjust the width of the abutting swim lane?

I have been searching to see how to do this but have not found it yet

Hi George 

Thanks for continuing this thread! Adjusting the width of a swimlane won’t automatically adjust the width of the abutting swim lane. It is currently only possible to directly adjust a lane’s width individually by dragging from its top or right-side border. However if you click and drag on the bottom/left border of a lane you will move that lane and this will cause the width of any lanes below or to the left of it to be indirectly resized. 

To learn more about how to work with swim lanes in Lucidchart please read through our Diagram with Swim Lanes article from the Lucidchart Help Center. 

Hope this helps!

Same question as Flavia D. 

It would be very helpful if moving one swimlane divider would simultaneously re-size lanes on either side.
