What size of door?

[CalvinHobbes]

Decided to knock a door from spare bedroom into bathroom next door. Want to minimise how much door swings so thinking about wardrobe style doors hinges each side so half size. I don't want sliding or bifold. What size of opening do you think?

450mm door is a standard sort of size for a double opening wardrobe or cupboard.

900mm of doors plus frame. I doubt you will get a smaller standard door.

next one up is a 610mm. 
I have both. One is boiler room and other is cupboard off kitchen.
