AutoCAD: Why my dimensions texts are always extremly small?

Hi Aya, You have two two ways:
1- You can check the the file units from "format" --> "units"
2- Or you can edit the size from the overall scale in the "dimension style manager" of shortcut (D) then modify and go to tab "fit" and change the "use overall scale" Hope this will help you, if don't i can figure out other options.

Hi, When u do one dimension, select & using Quick Properties you'll hv the text height field, change that number until you'll hv the proper height, you can apply that property to all the new dimensions by using brush format.

Your tdimension text can be changed under format, dimension style, text, there youchange your text height to the height you want your text to appear on paper aftert printing. but ensure you have put the correct overall scale for the size of paper you are using
