Tu as toutes les formes et les mesures ici :

On ne dirait pas que Taylor fabrique de modèle de forme "Concert". Ou c'est la GS mini ?
Qu'est-ce que tu appelles "la tienne" ?
Sinon je ne crois pas qu'il existe de "standards" précis pour les mesures... ça semble (sauf erreur de ma part) différer légèrement selon le constructeur.

Concert (O)*
Measuring about 13½" at the lower bout, O-size guitars were considered large when they were introduced in the mid-19th century. Today, they are an excellent bridge between a parlor - which some players find too small-and larger guitars, offering great playability and intimate tones.
Grand Concert (OO)*
Typically measuring about 14¼" at the lower bout, the OO's larger dimensions produce a more muscular voice that works well for a variety of playing styles. This size is often used for acoustic-electric guitars because it offers a balance between good acoustic sound and controlled resonance when amplified.
