I'll tell you
Whitworth 1/4" (British Standard Whitworth) introduced in 1841
was the standard size for the thread of a tripod for an ordinary (domestic, amateur, hand-held size) camera. Used in every country in the world. Including Leica, Zeiss, Minolta, Olympus, Kodak, Nikon, Canon etc.
There is pretty sure to be a socket for one in the base of whatever camera you have, that you used before you got that phone.
And the same tripod fits ordinary binoculars, but you won't have noticed the socket because it is usually hidden behind a removable cap on the Objective end of the hinge-bar on ZCF pattern instruments.
The thread is quarter-inch diameter; 20 threads per inch, 55° angle, rounded tips.
The reason it is ever so slightly different now is that (almost) nobody uses Whit. any more, and since the 1950's the American 1/4" UNC thread has become more common (it was developed from the Whit.) It is 1/4" diameter; 20 threads per inch... but the angle is 60° and the tips are flat. As a Septic engineer would say, "near enough."
