Why fov 103 is considered standart nowadays?

[Dribbler]

As many big fps titles like OW, Apex, PUBG, Valorant, Splitgate etc use 103 horizontal fov as default/maximum one I was wondering what's the science behind it? Like you can have a more round number like 100 or 105 but they still go with 103. 

My only guess would be that while hfov 90 is 4 screens for a full 360 turn and hfov120 is 3screens then ~102.9 hfov would make a middle ground between those two with 3.5 screens /360

@DPI Wizardsince you done countless fov measurements along with sens for every game on this site mb you found some logic or consistent pattern for this?

I think Overwatch was the game (or at least amongst the games) that popularized 103 as FOV (Apex is different), and with their success a lot of later games use 103 as either their default or maximum to make the transition for existing players as smooth as possible.

The reason they landed on 103 is probably not more interesting than at that FOV they felt the view, environment, weapons and gameplay looked the best and rendered without issues.

Also the (rather sensible) argument of "the default value that the players of our direct competitors are most used to will be the path of least friction for our game" plays a part.

Exactly why you also see .022 as a default yaw value in many off-shoot engines since Source, and why Activision/Blizzard have standardized to .0066 in all their FPS games
