Dynamic symbol size

The ability to have symbols whose size adjusts based on the zoom level.
For example, a square symbol representing a tile grid cell that scales dynamically with the zoom, so that it remains proportional to other displayed elements at any scale.

Hi @GregoireCatineau,

If I understand your request, this is very achievable using ArcGIS Pro.
There are a few different workflows, depending on if you would like to set the dynamic scale for a layer or rather a specific feature layer.

To set the dynamic scale for an entire layer, simply navigate to the layer in the contents pane > Right-click > Properties > Under Properties pop-up, select General and you'll see Visible Scale Range (choose 'Show layer between these scales only). Then specify the Maximum and Minimum scales.

Lastly, if you have a layer with 'Unique Value Symbology' and you want a specific feature to dynamically scale

Lastly, if you have a layer with 'Unique Value Symbology' and want only a specific class/feature to dynamically scale choose Format Symbol > Properties > Symbol > choose 'Enable scale-based sizing.'
From there, you can customize the size of the symbol at multiple different zoom levels.
I'll share a video below for easier understanding.

Thank you very much @Debert for your reply.
I actually need to automatically scale the symbols in my map, point symbols that represent a matrix.
The symbol simply needs to be proportional to the scale, without defining any specific levels or steps.

bests regards

Gotcha. I believe you are looking for Proportional symbols, which is also located in the Symbology pane.
I'll share a link on how to achieve this here ArcGIS Pro Proportional Symbology.

Cheers!

@GregoireCatineau Have you tried setting reference scale? https://pro.arcgis.com/en/pro-app/latest/help/mapping/properties/map-reference-scales.htm
