Portwest Size Guide: Workwear, Trousers and Gloves
How do Portwest sizes work?
Portwest sizes clothing to your body. Measure your chest for jackets, tops and coveralls, your waist for trousers and around your palm for gloves, then find the size in the charts. A 108 to 112 cm (42 to 44 inch) chest is a Portwest L.

Portwest's body size charts in one place: chest, waist, inside leg and glove sizes in centimetres and inches, for men's and women's workwear.
Portwest sizes its clothing to fit your body, so the charts below are body measurements, not garment measurements. Measure yourself, find the measurement in the chart and that is your Portwest size.
How to measure
Chest. Around the fullest part of your chest, under the arms, with the tape level.
Waist. Around your natural waist, where you wear your trousers.
Inside leg. From the crotch down to the ankle, on the inside of the leg.
Hand. Around your hand at the palm, below the knuckles, not including the thumb.
Use a soft tape measure over light clothing. If you fall between two sizes, go by your larger measurement, and size up if you wear thick layers underneath.
Men's jackets, tops and coveralls

Gloves
Glove sizes run from 5 to 13. The number is the distance around your palm in inches, so a 9 inch (23 cm) palm is a size 9, a Portwest L.
| Size | Glove size | Palm circumference (inches) | Palm circumference (cm) |
|---|---|---|---|
| XXS | 5 | 5" | 13 cm |
| XS | 6 | 6" | 15 cm |
| S | 7 | 7" | 18 cm |
| M | 8 | 8" | 20 cm |
| L | 9 | 9" | 23 cm |
| XL | 10 | 10" | 25 cm |
| XXL | 11 | 11" | 28 cm |
| 3XL | 12 | 12" | 30 cm |
| 4XL | 13 | 13" | 33 cm |
Fit varies a little from style to style, so each Portwest product page shows the chart for its own sizes, and a link to Portwest's spec sheet where there is one.
