I've not checked lately, but last that I searched for Cabin Views on a.net, there was a pic of an A330 & an old A320.

The A330 has 45" or so. They are reasonably comfortable seats.

A320s are a mixed bag. The newer ones have about 40~42". Tail # RP-C3227 (& perhaps some others) has no coat closet ahead of 1A/B. These
particular seats must have at least a yard/meter between the seat & bulkhead.
The newer A320 seats are comfortable, too.

The older A320s have economy seats with the middle seat blocked out. I've not seen any of these on an international flight for a year or so. But you could encounter one.

If it's on an A320 ask for 1A/B.
