The correct reading is きぼ (on'yomi-on'yomi). 規 (き) and 模 (ぼ) are standard on'yomi, common in formal compounds. Misreadings like きぽ or ぎぼ occur from incorrect half-rendaku or rendaku, or mispronunciation of 模 (ぼ). It refers to the "scale" or "scope" of something, indicating its size, extent, or magnitude, such as a project or organization.

正しい読み方はきぼ（音読み-音読み）です。規（き）と模（ぼ）は標準的な音読みを保ちます。きぽやぎぼなどの間違いは、不適切な半濁音化や濁音化によるものです。物事の大きさや範囲、広がりやスケールを意味します。
