It is an historical thing. Basically the integer type size was choosen in order to represent a 'meaningful' amount of numbers, efficiently with the computers available at the time of the programming language design.
See, for instance: c - What is the historical context for long and int often being the same size? - Stack Overflow[^].

No, that's quite wrong. Very few languages default to a 16 bit integer these days as it's range of values is far too small for modern requirements: −32,768 to 32,767 only.

In Java, an integer is not 16 bits, but 32 - a short is 16 bits, and the same applies in nearly every modern compiler: C#, C++, even modern C compilers use a 32 bit integer.

That didn't used to be the case when processors were 8-bit and memory was tiny (32K or 64K address spaces don't encourage 32 bit integers) and C compilers used 16 bit integers by default.

Only seriously old systems and compilers aimed at embedded environments will default to 16 bit integers these days.

In most programming languages, the integer is a 16-bit value as to java and visual basic 32- bit integer. Have a research on the reasons behind such subtle design differences.
