First answer:
Ask the transfer house that will do the transfer. There’s not a single worldwide standard, and different equipment needs different framesizes, and not all projects are in the same aspect ratio.
But:
You work at 24 fps.
Most film-out devices have a maximum resolution of 2048×1556. But we almost never use that much vertical resolution, because of widescreen aspect ratios.
Usually starting at 2048 pixels wide (what we call ‘2k’) is a good idea.
Personally I do a lot of feature film work at 1920×1080, because apparently they like to stay compatible with HD framesizes… Makes it easier to play out to HD tape I guess.
But seriously: consult with the transferhouse for specifics.
