.38 caliber REVOLVERS can be several different lengths, depending on the frame and the barrel of the revolver. Typically one of the smallest is the S&W Chief's Special (Mdl 36) which is about 6.5 inches long (2 inch barrel). I have others over 12 inches long. .38 derringers are smaller still- about 4.5 inches.
One would think that .380 ACP and .38 Special would be the same size--namely 38-hundredths of an inch. But there can be some flexibility in stated caliber and actual caliber. Long story short, .380 ACP is the same diameter as a 9mm, roughly .355 caliber. .38 Special is basically .357 caliber.
38 special is a full length 38 cartridge whereas a 38 S&W cartridge is also a 38 caliber but it has a shorter case.

38 is the size. This answer is actually correct, but more specifically, .38 special (and many of the other .38 caliber cartridges) are actually .357. The caliber ".38" was chosen to distinguish between .357 magnum and .38 special.

Caliber is the diameter of the bore of a firearm. It's expressed in hundredths or thousandths of an inch, as in .45 caliber or .380 caliber. Curiously, the actual diameter of a .38 caliber slug is 0.357 inch.
