Reply To: Size font bbpress

Without a url or screenshot I can’t really help further – there are several places where bbpress has font sizes eg

#bbpress-forums ul.bbp-lead-topic,
#bbpress-forums ul.bbp-topics,
#bbpress-forums ul.bbp-forums,
#bbpress-forums ul.bbp-replies,
#bbpress-forums ul.bbp-search-results {
	font-size: 12px;
	}

#bbpress-forums .bbp-forums-list li {
	font-size: 11px;
}

#bbpress-forums div.bbp-forum-title h3,
#bbpress-forums div.bbp-topic-title h3,
#bbpress-forums div.bbp-reply-title h3 {
	font-size: 16px;
 	}

#bbpress-forums .bbp-forum-info .bbp-forum-content,
#bbpress-forums p.bbp-topic-meta {
	font-size: 11px;
	}

and lots more

I can only suggest you try some of the above in your custom css BUT put ‘!important’ after the px part to ensure that it is not overwritten eg

#bbpress-forums ul.bbp-lead-topic,
#bbpress-forums ul.bbp-topics,
#bbpress-forums ul.bbp-forums,
#bbpress-forums ul.bbp-replies,
#bbpress-forums ul.bbp-search-results {
	font-size: 12px !important;
	}
