I would be bored is, literaly 'Me aburriria'. O 'Estuviese aburriendo', for example in 'If I would be bored I would just leave', for conditional 'Si estuviese aburrido me iria'. Seria aburrido is for 'it' or 'this', this would be boring, or it would be boring. Then yes it changes ser for estar, but don't make it complicate, for a first person feeling something, like boredom, hapinness or sadness is always estar. Take care, Alejo.

It is difficult to give a translation without a context. But here you are the most common ones:: Sería aburrido= It would be boring Estaría aburrido= I would be bored (but also in some cases it would be boring) Me aburriría= I would get bored

Hello, I also would expect "estaría aburrido" or "me aburriría" and not "sería aburrido".

I've got it! The difference is between "I am bored" which is a temporary state for you so uses estar, and "It is boring" which describes a permanent characteristic of the thing so uses ser. So in your example you went from "*I* am bored" to "*It* would bore me", changing the subject of the sentence and hence changing the translation. Taught me something.

"Sería aburrido" means that something (it) would be boring.. example: Vivir solo en mi casa sería aburrido/ it would be boring to live alone in my place..
