Men's suit and jacket sizes chart

The highlighted row shows UK 50 and its equivalents. These are standard conversions used by most retailers; some brands cut larger or smaller, so if you are between sizes, go by your measurements.

Fitting a UK 50 jacket

UK and US suit sizes are the chest measurement in inches, so a size 50 jacket is cut for a chest of about 50 in (127 cm). To measure, wear a shirt and run a tape around the fullest part of your chest, under the armpits and across the shoulder blades, keeping it level and snug but not tight.

Each step in the chart is 2 in of chest. UK 48 is 5 cm smaller in the chest (122 cm) and UK 52 is 5 cm larger (132 cm). If your chest falls between two sizes, tailors usually suggest the larger jacket, because it is easier to take in a jacket than let it out.

Retailers label this size XXL/3XL, and Japanese sizing calls it 3L. Jackets are also sold in short, regular and long fittings, so check the length as well as the chest, and try the jacket with the sleeves and shoulders in mind, since those are the hardest parts to alter.
