I've thought long & hard about this. The numbers mean nothing. The longest iron in your bag should be the longest, with the least loft, you can hit reasonably consistently. For some it will be the 5 iron, for me, with a very forgiving set it's the 3 iron, with standard loft 1½" longer than standard. The 9 iron should be around 4° straighter than your pitching wedge, in my case 42°. The other clubs should then have lofts & lengths evenly spaced between your 9 iron & longest iron. Once you've done this, measure how far you carry each one, either on the range or on a simulator, using the ball you normally play with, and that's it. Get some woods & hybrids to fill the gap between your driver & longest iron and you've got a set that suits you.
I built my set this way & it works brilliantly. The 3 iron is 1½" longer & I get an important 15 yards extra with it. All the other irons, 4 to 9 are varying amounts longer than standard, with the 9 iron ½" longer than the pitching wedge. I think I could hit the 3 iron with a little less loft so I may have the lofts of 3 to 8 strengthened a bit to give an even spread.
I've never met a club fitter with this approach, it just seems logical to me, and, more importantly, it works.
