Those charts have always been a bit iffy but my brother-in-law claims that at 5’9” and 250 lbs. that he’s just heavily muscled and big boned. I just consider him fat.
The last man I knew who was 5’8” and actually was heavily muscled with a low bodyfat ratio only weighed 205 and he looked like a short Mr. Universe with huge muscles, if you painted him green and photographed him so that you could not guess his height he would have looked like Lou Ferrigno in the old Hulk TV show. On the other hand I am six four, just eight inches taller and when I used to weigh 205 I looked positively scrawny, yet the charts say that is the most I should ever weigh.
