CALCULIER

You lengthened or shortened your irons — and now the lie angle is wrong. The head still reads the same on the gauge, but the club plays differently. Half an inch of added length makes it play roughly 0.5° to 1° more upright, even though nobody touched the hosel. The toe sits higher and the face points further left. CALCULIER works out the static lie angle each head has to be bent to so it plays exactly as it did before. HOW IT WORKS Enter your clubs: standard lie, standard length, new length. For every club you immediately see: • Plays Like — how the club feels after the length change • Adjust To — the static lie angle that cancels it out • Final Lie — the rounded target for the bench, including your own fitting adjustment AN EFFECT MODEL YOU TRUST Conservative 0.5°, middle 0.75°, strong 1.0° per half inch — or a value of your own. Because the real effect is a range rather than one number, the 0.5°–1.0° span sits beside every result. WORK ORDER A finished list for your club builder: only the clubs that actually need bending, each with direction and degrees. Share it or print it. THE WHOLE SET AT ONCE Shift every length by the same amount, correct every standard lie, or lay a wrist-to-floor adjustment across the entire set in one go. ON THE RANGE AND AT THE BENCH Turned sideways the iPhone shows the full table, and on iPad the work order sits right beside it. YOUR DATA STAYS WITH YOU No account, no sign-in, no connection needed. Saved club sets live on your device and nowhere else. Every figure is a starting point for the conversation with your club builder, not a substitute for it. Not every head takes every bend.
