Quick answer
For a person 175 cm tall with a 40 cm neck using a Four-in-Hand knot, this guide suggests a 145–152 cm necktie. This is a shopping range, not an exact tailoring measurement. After tying, check that the front tip reaches the belt or waistband.
How to use
Enter the known values, check the selected units and assumptions, then calculate. Compare the result with the worked example. Copy, print or export the table when you need a record. Measure height and neck circumference in the same selected unit. The shopping guide starts with short, regular and long ranges. A neck of at least 18 inches or a Full Windsor at heights of at least 183 cm moves the suggestion up one band.
Formula and method
Height <168 cm → 135–145 cm; 168–188 cm → 145–152 cm; >188 cm → 155–165 cm. Neck circumference ≥45.72 cm → ↑
Worked example
175 cm; 40 cm; Four-in-Hand → 145–152 cm (57.09–59.84 in)
Assumptions and limits
This is a transparent shopping heuristic, not an exact tailoring measurement. Torso length, tie fabric and trouser rise affect fit. The tied front tip should reach the belt or waistband. Check the seller’s actual dimensions and try the knot before buying.
