Size Guide

Choose your product below to find your size.

Belt size guide

Belt sizes are measured from the buckle to the middle hole—not the full length of the belt.

Measure a belt that fits you well:

  1. Lay it flat.
  2. Measure from the buckle to the hole you normally use.
  3. Choose the closest Portia size in centimetres: 95 cm = size 95.

Between sizes? Choose the larger size for a little extra room.

Don’t have a belt to measure?

Use a tape measure around the place where you wear your belt, over your trousers. Keep it snug but comfortable, then choose the closest size in centimetres. For example, 95 cm = size 95.

Swim shorts size guide

To find your size, measure a pair of swim shorts that fits you well and compare with the chart below.

Lay them flat and follow the measurement points in the illustration. Measure the waistband without stretching it first, then gently stretch it to compare the stretched waist width.

All measurements are in centimetres. Widths are measured across the garment laid flat, rather than all the way around.

"1/2" in the size chart means that we only measure one side over the swim shorts and not around.
