In a steampunk setting, how large could a tube-based messaging system feasibly be? Could multiple cities be connected this way?
Sure there'd be telegraph too, but sometimes writing on paper is better than Morse code.

How about: as large as it needs to be for your game.
Practically speaking, I'd avoid having the tubes go between cities. Repairing a busted tube can be a pain in the ass if it's miles and miles away and can be insecure; telegrams and couriers are better suited for these messages.
I don't see why pneumatic tube systems couldn't go between cities in the context of a steampunk setting. Remember too that whole pneumatic transit systems have been designed:

Not to mention the modern day hyper loop.

I'm still with this anon. As long as there's an alterbative like telegraph, aether or crystalograph, it'd probably be more efficient for long distances, while the pneuma is good for quick short distance communication.

The hyper loop will never work.

As others have said, multiple cities would be unlikely (also telegram, fax, teleprinters and the teleautograph https://en.wikipedia.org/wiki/Telautograph were more suited to long distance, only requiring wires), but real life proved that tubes work in a city, especially if you have enough money (they weren't cheap to run)

As big as you have enough random cogs and shit to stick on.
