Once someone asked me "I want a small guitar,because I have small fingers". My answer was that is definitely not the right choice, different guitar shapes has different work to do,what does different shapes do ? Best reason is different type of sound. Some sound bassy, some sound cranky,some sound mild or some might sound wild .Let us check out in brief:\n\n \n\n\n\n \n\n\n\nParlor Guitars\n\n\n\nThey are the actual smaller guitars They are generally good for finger picking,yet they sound good.\n\n\n\nConcert, or Model \u201cO\u201d\n\n\u201cThey are slightly larger in size than the parlor, and are also suited well for fingerpicking.\n\nGrand Concert, or Model\u00a0 \u201cOO\u201d\n\nThe Grand Concert was derived from the shape of the classical guitar, after it was standardized by the work of Antonio Torres. Its one of the quietest model of acoustic guitar. It has a solid mid-range register, so that it is a great all-around guitar. Gives you better access to the higher frets.\n\nOrchestra Model,\u00a0 Grand Auditorium, or Model \u201cOM\u201d or \u201cGA\u201d\n\nThis model is also sometimes called an Auditorium or \u201cOOO\u201d.\u00a0 It is a mid-size guitar, with great balance, volume, and projection.More treble on the tonal side.\n\n\n\nDreadnought\n\n\n\nThis is the most common acoustic guitar shape.\u00a0 Its a large-bodied guitar named after a British Battleship of the same name for its size.\n\n\n\nJumbo and Super-Jumbo\n\n\n\nThese are the largest guitars, often used for strumming because of their great bass response.\n\n\n\nSo if you are going to buy your next acoustic guitar, or if you are a new learner, do follow what you intend to do with your acoustic guitar, and buy yourself the right one!
