Set Against Posture
Measured with you in your actual address posture, not a generic chart based on height alone. Two golfers of the same height can need lengths half an inch apart.

Iron Fitting
Sheet 04 on the rack, and the one that produces the most re-check visits. Length, lie and loft measured club by club, not averaged across the set.
The Problem
A "Set" Rarely Ages as One Piece
Nine or ten heads on the same rack do not wear or drift evenly.
Irons are sold as a matched set, but they do not stay matched forever. The scoring clubs — pitching wedge through 8-iron — take the steepest, most repeated contact and are usually the first to show lie drift. Longer irons, hit less often and with a shallower angle of attack, tend to hold their spec longer. On an audit of a bag that has not been checked in several seasons, it is common to find the short irons flat and the long irons still within tolerance, which means a "the irons need regripping" conversation is often really a "three of the nine irons need bending" conversation once the actual numbers are on the table.
Fitting a set as nine identical numbers ignores this. We measure and log every iron individually, both at the original build and at every re-check, specifically so this kind of uneven drift gets caught club by club instead of averaged away.
What Gets Measured
Length
Lie
Loft
Every Club, Same Three Numbers
Read at Impact, Not Address
Dynamic lie — how the sole meets turf at the moment of contact — is what we build to, checked with impact tape on the lie board rather than a static reading alone.
Gapped Club to Club
Consistent degree spacing between neighbouring irons, checked as a full progression rather than club by club in isolation, so no two irons overlap in real carry distance.

Why Irons Get the Shortest Interval
Seventy Rounds, Not a Full Season
Irons are on the shortest standing re-check interval of any category on the ledger — every seventy rounds — because they take the most contact with turf and the most repeated stress on the hosel of any club in the bag. A golfer who plays through a full Inland Northwest season, tee to first frost, will typically cross that threshold before the following spring.
The full standing interval schedule, across every category, is on the fitting method page.

Wedges Are Fitted Separately
Wedges wear faster and are measured against different variables than the rest of the iron set.
