Rh5 and rh6 text big size

HELLO TO EVERYONE

As you can see in the picture, the text ones are distorted when they open with rh6 while rh 5 is normal.

Where I couldn’t find the layout scailling in RH6.

help please

Best is to use the ‘scale all sizes’ option in your dimension style(s) to scale everything to proper size for layout space and then (if needed) use the model space scale to adjust for model space.

Assuming that both model space scaling and layout space scaling are enabled
