This suit size calculator by height and weight gives you a quick starting point when you do not have every suit measurement available. It uses your height, weight, and waist size to estimate a standard jacket size and length category.
The calculator uses your height to estimate whether you need a short, regular, or long jacket length. It also uses your waist size and body size as a practical shortcut for estimating your jacket number.
Suit sizes are often written as a number plus a letter, such as 40R, 42L, or 38S. The number usually refers to the jacket size, while the letter refers to the jacket length. S means short, R means regular, and L means long.
Stand barefoot against a wall and measure from the floor to the top of your head. Height helps determine whether your suit jacket should be short, regular, or long.
Use a reliable scale on a hard, flat surface. Enter your current body weight in pounds or kilograms depending on the selected unit.
Measure around your natural waist, above your hips and below your ribcage. Keep the tape level and snug, but not tight. Waist size helps improve the suit size estimate when chest size is not available.
Height and weight alone can describe very different body shapes. Adding waist size gives the calculator a better starting point for estimating the jacket number and overall fit.
A suit size calculator by height and weight is useful for a fast estimate, but a full measurement-based calculator is more accurate. Chest, shoulder, sleeve, waist, and inseam measurements can provide a better fit recommendation.
This calculator gives an estimate based on common sizing patterns. Suit sizing can vary by brand, cut, fabric, posture, shoulder shape, and fit preference. Always compare the result with the brand’s size chart before buying.

Height and weight can give a quick estimate, but they are not as accurate as chest, shoulder, sleeve, waist, and inseam measurements. Body shape can vary even between people with the same height and weight.
A suit size such as 40R usually means a 40 inch jacket size with a regular jacket length. A 40S would be shorter, and a 40L would be longer.
If you are between sizes, sizing up is often safer because a tailor can usually take in a jacket more easily than add room to one that is too tight.
It can help you choose a starting size for online shopping, but you should still check the brand’s size chart. Fit can vary between brands, slim cuts, regular cuts, and tailored cuts.
