Why all electric guitar wan ? .... Acoustic guitars can right ? ... i mean it's the "guitar Paradise" ....
How Body Shapes Affect Tone ProductionWell .... the bigger the guitar, the louder it will sound (huh!) and, consequently, the body width and depth will produce more bass response. The difference between all these guitars is the depth of the body. Their scale lengths are standard 25.3" (643mm)

Model: GJ46SCE (Jumbo Guitar)
Brand: Fender
Body Depth: 3.87" (Front) to 4.87" (Rear)
Nickname: Big Mama guitar, Jumbo

With bodies approximately 17 inches wide and 5 inches deep, jumbos are the cannons of the acoustic guitar world. Typically made with backs and sides of maple to recover clarity in the tonal spectrum ... wah .... These huge guitars can certainly fill a room, at alone a hall with sound.
But ... haha, guitars of this size and power are usually harder to record with, so, most players will choose smaller bodied instruments to make recordings and will leave the jumbos for their live performance.
Most jumbos are made of rosewood which produces a more mellow tone than maple and rosewood are very popular for their power and rich resonance.

Steel-string guitars with body widths from approximately 14 inches to 16 inches fall into categories known as
i) Concert
ii) Grand concert
iii) Auditorium
iv) Grand Auditorium
Model: GDC 100 SCE (Florentine Cutaway) Concert Guitar GC12
Brand: Fender
Body Depth: 3.62" (Front) to 4.40" (Rear)
Nickname: Folk guitar, concert
Model: GC12
Brand: Fender
Body Depth: 3.5" Front, 4" Rear
Nickname: Folk guitar, Grand Concert

The smaller concert and grand concert sizes accentuate the middle and upper end of the frequency range and because they lack deep bass response, these guitars are usually built with mahogany or rosewood back and sides to give them an extra warmer, better balanced tone. Keep in mind about maple bodies as these tend to be too bright and harsh.

Model: GA43SCE
Brand: Fender
Body Depth: 4" (Front) to 5" (Rear)
Nickname: Grand Auditorium

Mid-sized Auditorium and grand Auditorium models bring the widest palette of frequencies and tone colours to the mix because all types of tonewood, various scale lengths and decorative appointment are used in these categories, along with many variations in body shape. These body sizes are generally believed to be the best guitar for tonal balance, clarity of individual notes and blend of chord structures. These guitars are the favorites of modern finger-style players.

Model: DG10
Brand: Fender
Body Depth: 3.94" (100mm) to 4.92" (125mm)
Nickname: Dreadnought Guitar, "acoustic guitar"

Little history lesson for you guys. This body shape took its name from a battleship that was used during the early 1900s which is also known to be wide across it's mid section. The overall shape has been described as rectangular with a soft waist curve yielding a large soundboard and strong tone character across the full sound spectrum but emphasizing the low-mid range.
These near-jumbo sized instruments have dominated the acoustic guitar world since the 1930s and no matter whom the manufacturer, the width, length and depth of the body are fairly standardized with only a few exceptions. Hundreds of thousands of dreadnoughts are sold in the world each year and have in fact become what most people think of when you go to a guitar store and say "acoustic guitar"
