just figure what head-tube length you'd prefer. Head tubes vary quite a bit in length, so check them out on the geometry charts of the frame you buy.
For example, I had a BMC Streetfire with an effective top-tube of 56.5cm, but the head-tube was relatively large: 175mm (integrated). The 56cm Cervelo Soloist has a 160mm head tube
Try to figure out your prefered bar height, then workout how many spacers you could handle in there.
Custom is another option, although more expensive
