1. Chest size

Take a similar item of clothing that fits you really well. Lay it on a table and measure from under the armpit, to under the other armpit and then double the measurement.

2. Waist size

It's probably the one measurement you won't need to take because it's the one that's most referred to. This measurement should be taken at the waist level, where your pants are normally buttoned. To avoid having tight-fitting trousers, leave enough room for one finger to fit between the tape measure and your body.

3. Inseam

An easy method is to use a fine fitting pair of pants and to simply measure the length between the crotch seam and the bottom of the pants.

4. Sleeves

A practical way of measuring your sleeve size is to take a fine fitting shirt, and measure the distance from under the armpit to the cuff.

5. Hats

Measure around your forehead, approximately 1cm above your ears. Many hats, however, are one size fits all or sold in small, medium and large sizes.
