I now have the text size set to mPaint.setTextSize(15) , but I need it to be 15sp , how should I translate / specify 15sp , what should I do to display the correct size on the screen correctly? I tried to use getResources().getDimension(R.dimen.letters_height) , but the inscription on the screen is less than 15sp.

    Paint.setTextSize() takes the value of the text size in pixels. To set the size in other units, you need to convert them to pixels. This is done like this:
    from resources:

     int sizeInPx = context.getResources().getDimensionPixelSize(R.dimen.letters_height);

    From the number:

     int sp = 20; int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, sp , getResources().getDisplayMetrics());

      @Lucky_girl, TypedValue contains constants for all types. Look over there - Vladyslav Matviienko
