Have you upgraded your Dynamo graphs to Revit 2023 and they look like this?
Thankfully we have a few options to fix this.
Option #1
comes to us from the Dynamo forums. Jacob was friendly enough to create a batch resizer graph that will fix a directory of DYNs.

It works really well, but (at the time of this post) has a few issues if you rename nodes with special characters. For instance, Rhythm nodes are renamed on placement with the prefix of ʳʰʸᵗʰᵐ|.
Your option for fixing this is to open the DYN in notepad and replace those characters with something else, (not great, but still doable).
Option #2
is to use a new tool in monocle to resize the current graph on the fly. The new tool, Resizerer, will allow quick adjustments with rapid feedback. I want to note, that Resizerer was definitely inspired by Jacob’s original graph and is the result of using that logic directly in the Dynamo API.
