Suit Size
Build a suit size from chest and height, including sleeve length.
About Suit Size
Chest maps to a letter band adjusted for fit style, while sleeve and inseam are derived from height. Suits are bought by jacket and pants separately, so computing both avoids a torso-perfect, leg-short pair.
Formula
Suit Size
Letter from chest; sleeve ~20% of height
- inseam
- Pants length from crotch to hem, ~44% of height

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
