How This Tool Works

Select a US/UK neck size in inches and the converter shows the matching EU shirt size, international size label, and chest range. The reference table highlights the selected neck size so you can compare nearby options.

Input: US/UK neck size, such as 15.5 inches.
Output: Equivalent EU size, international label, and chest range.
Reference: US and UK dress shirt sizes are based on neck circumference.

Why This Matters for Fit

Men's dress shirts are often sold by neck size in US and UK sizing, while European listings use numbered sizes and many retail charts include XS through XXXL labels. Comparing these systems helps reduce guesswork when shopping across brands or regions.

Use the chest range as a secondary reference, especially when a product listing gives only an international size label.

Common Mistakes to Avoid

Do not treat labels as exact measurements: XS, M, and XL vary by brand and cut.
Measure the neck comfortably: Leave enough room for normal collar fit instead of measuring tight against the skin.
Check the brand chart: Use this converter as a cross-system reference, then confirm the retailer's size notes when available.
