Great overview article on fundraising and valuation, including a chart that will give founders some basic rules of thumb. Mostly, you’ll want to think about how much you need to raise, and look to that as a guideline of what your valuation SHOULD be.

The expectation is that companies are roughly going to double their valuation at each raise. This isn’t to say that a 2x increase in value is your target, it’s the minimum, the floor. The art of raising a round it to raise enough money to get to a significant milestone, and not too much money taking too much dilution too soon.
