I'd guess that the larger, the more durable, but the size of the device
often limits the size of the connector that can be used.
But some devices may produce only mono sound, while others produce
stereo sound. Again, different connectors are appropriate -- not
different sizes but with either two or three contact points.

And cellphones often have mono headset and microphone on thesame tiny
plug - you don't want to be able to just willy-nilly plug in a set of
sterio headphones with the 1/8" plug. Might be different impedence

The 1/8" is fairly common. The large older one is 1/4" is used mostly on f
ull size headphones in professional settings. You do find it on older home
stereo gear. There is a smaller 3/32" but it's not very common. So I'm n
ot sure why you are having size problems.

They started with big ones, 100 years ago. 1/4" As things have gotten
smaller, the big plugs were too big for the little devices.
I have loads of adapters, but only for temporary use until I get the
right product. Adapters are a pain -- they stick out -- and a little
cell phone or Sandisk MP3 player won't have the power to drive the 2 or
2.5" speakers in a large set of headphones. Even if it did have the
power, it would run the battery down too fast.
No, except that some headsets need a microphone, and others are
monoaural or stereo, maybe with no microphone. For talking on the
phone, there could be two earpieces but they would have the same sound,
Cell phones used to have 2.5 mm plugs, because cell phones used to be tiny.
Early AMPS (analog mobile phone service) cell phones in the 1980's were
essentially suitcases, and were called "car phones". By the early 1990's, cell
phones had shrunk to the point that they looked like household cordless phones.
A race was on for phones to be smaller and smaller. The smaller the phone the
more "status" it showed. Within about a decade, by the 2000's, phones became
ridiculously tiny. These tiny phones used 2.5 mm headphone jacks to save
space. Every cubic millimeter counts in a compact design.
The trend now is for phones to be larger, because they are now essentially
small tablet computers, and the screen size matters. Nobody wants to use
a 1.5 by 2 inch screen.
These modern smartphones tend to have the usual 3.5 mm (or 1/8") jacks that you
also see on computers.
I.e. long story short; your phone is probably outdated.
You asked and answered your own question, but your premise is wrong. The
headphone jack on both my computer and cellphone are the same size. Why
did you buy the brand you did if that was going to be a problem?
