I had the same problem. I wanted to get the same aspect text ratio on every screen. No dp nor sp worked for me. The only solution that works for me is to create a dummy textbox (not visible) at startup then get the textsize and multiply for some ratio (depending on what you actually want). This value should be used to set text size dynamically to your controls. At least it works for me because the same aspect remains on every different screen.

You can go through this, I used the below method to scale texts on different screen resolutions and sizes.

To define a range of text sizes and a dimension programmatically through the support library, call the TextViewCompat.setAutoSizeTextTypeUniformWithConfiguration(TextView textview, int autoSizeMinTextSize, int autoSizeMaxTextSize, int autoSizeStepGranularity, int unit) method. Provide the text view on which it needs to be applied,the maximum value, the minimum value, the granularity value, and any TypedValue dimension unit (like TypedValue.COMPLEX_UNIT_SP).

Is there any equivalent to this in Jetpack Compose? – Sparsh Dutta Apr 21 '21 at 09:59 — Sparsh Dutta, Apr 21 '21 at 09:59
