How to measure yourself for clothing and shoes
Use a soft fabric tape measure, not a rigid metal one. Measure directly against skin or light clothing, standing naturally. Keep the tape level all the way around your body and snug without pulling it tight enough to compress the skin.
Bust or chest
Wrap the tape around the fullest part of your bust or chest, keeping it level across your back. Breathe normally and take the reading without holding your breath in or out.
Waist
Find your natural waist — usually the narrowest point of your torso, roughly level with your belly button, not where your trousers currently sit. Measure around this point without pulling the tape tight.
Hips
Measure around the fullest part of your hips and seat, typically about 20cm below your natural waist, with your feet together.
Inseam
Measure from the crotch seam of a well-fitting pair of trousers straight down to where you want the hem to sit, or measure leg length directly down the inside of your leg from crotch to ankle.
Foot length
Stand on a sheet of paper with your full weight on the foot. Mark the back of your heel and the tip of your longest toe, then measure the straight-line distance between the two marks. Measure both feet — most people have one foot slightly longer than the other — and use the longer measurement when converting sizes.
Tips for an accurate result
- Measure in the evening if possible — body measurements can vary slightly through the day.
- Ask someone to help with bust and hip measurements if you can; it's hard to keep the tape level while looking down at it yourself.
- Round to the nearest half centimetre rather than rounding up or down to a whole number.
- Re-measure if a result looks unexpected — a tape that's twisted or not level is the most common source of error.
