Topic: Size of the joysticks?

For any of you who have a Nintendo Switch and Xbox One/PS4, are the joysticks the same size? Would I be able to interchange my joysticks caps/covers between those consoles?
Sounds like a silly question, but I have custom joystick caps for my Xbox One and would like to use them on my Switch when I get it on Monday! I can't find the answer anywhere...haha

No. They are different sizes. Playstation in particular has been larger than the others. Switch is the smallest I think.

When the Switch first released I saw some whinging about the thumbsticks being smaller, but I actually really like them as they are.

Switch using the Joycon is smallest.
PS4 are large and rather in your face which is nice in many ways
Switch Pro Controller are great, middle sized ones, even if I prefer joycon in each hand.

Xbox One though...im not sure? I physically cant hold the controller due to injuries. But I hear like the Pro Controller, they hit that sweet spot.

Changing them may be doable, it deoends if the underlying mechanics will allow a different fit.
