The most critical dimension for fit is the length of the top tube.
Also check for the location of threaded eyelets for rack(r) and fenders(f/r). You really need these eyelets for a commuter even if you chose not to use them right now.
Be aware that std disc mount location can interfere with rack/fender fitting even if you have the eyelets. Ideally you want a frame with the disc mount on the
seatstay.
