[Solved] Limit comment length

What or where is "according the option?"

WHAT do you mean? I don't see those words anywhere

By larger, I meant the size of the font of the number not to increase it.

@dancer,

If you want to increase the font-size of the counter use the CSS code below: 

#wpdcom .wpd-editor-char-counter {
   font-size: 12px;
}

Put the code in the Top Admin Bar > Customize > Additional CSS > "Additional CSS" textarea, save it, delete all caches and check again.

I tried, but not enlarging. See attached if done correctly. Thank you very much.
