Have you ever wondered why your dimension text is always too small or big in CAD?

Actually, we can change the dimension text size using Dimension Style Manager.

Enter DIMSTY, as shown in the following picture,

In the popped-up dialog box, Click Modify button, as shown in the following picture,

Then in the dialog box, go to the Text tab and find Text height, as shown in the following picture,

We can make the dimension text bigger or smaller by changing the Text height value.
