The term describes a person with a large overall build, including height and body width rather than just one large body part.

身長や体の幅などが大きく、全体に大きな体格であるさま。shin chō ya karada no haba na do ga ō ki ku zen tai ni ō ki na tai kaku de a ru sa ma

大柄 (ōgara) is formed from 大 (ō, "large") and 柄 (gara, "build or form"), making the compound mean a large body build.

大柄 (ōgara) is used mainly for people, while 大きい (ōkii) is the general adjective for something that is large.
