How to measure?
As a guide most men need a jacket size approximately 4 – 6 inches bigger than their waist size. eg. 34 waist would usually be a 38” or 40” chest.
Sleeve length on a jacket is easier to measure than a jacket length and you just measure from the crown of the shoulder to the cuff.
If you ever have a problem with your trousers being tight around the top of the leg it may mean you need a larger waist size. As a guide if you measure around your seat, if it is approx.7 or 8 inches larger than your chosen waist size you may need to go up a size. e.g. waist 34” seat measurement 40” should be ok. Waist size 34” seat measurement 42” could be better to go for a 36” waist.
Measure yourself around the fullest part of your chest, keeping the tape measure level under the arms and across your back. Measure the chest at the fullest part, placing the tape close up under the arms. Or if you are a suit wearer quoting your usual size may be better.
Not relevant to a suit so we don’t need this at all.
Ask someone to measure you around your natural waistline. Which would be just above the trousers you are wearing. If you are mainly in jeans and not trousers or suits don’t be surprised if the measurement is about one size larger than your jeans size.
This measurement needs to be from the crotch to your ankle bone. You won’t be able to do it yourself. The measurement needs to be from the crotch to where your trouser is normally worn on the shoe. If you want to double check this size, you could measure the inside leg of a pair of your own trousers that you know are the right length.
Measure from the centre back of your neck to your hemline. As the arm length and jacket length can’t be varied independently of each other we would usually suggest it is easier to measure your arm length.
