What to Know Before Choosing a Leather Jacket Size
Buying a leather jacket online is so exciting! But picking the right size can feel a little scary. A "Medium" from one store might feel like a "Large" from another store. Your normal t-shirt size does not really help when buying leather.
But do not worry! If you take just two minutes to measure yourself, you can get a jacket that fits like a glove. This easy guide will show you exactly how to find your perfect size. Say goodbye to guessing, and order your new jacket with total confidence!
1. Why Leather Jacket Sizes are Different
Leather is not like a normal cotton t-shirt. It is a natural material. When a real leather jacket is new, it feels a bit stiff. But after you wear it a few times, it stretches just a little bit, gets super soft, and moulds perfectly to your body shape.
Also, every brand makes their clothes differently. A "Medium" in one store might be a "Small" somewhere else. Do not trust the tags on your old clothes! The only way to get a perfect fit is to use a tape measure and check our size chart.
2. Three Big Mistakes People Make

Before you start measuring, make sure you do not make these easy mistakes:
Mistake #1: Measuring Over Big Sweaters
This happens all the time! If you measure yourself while wearing a big hoodie, you will add extra centimetres. Then, your new jacket will be way too big and baggy.
How to fix it: Always measure yourself while wearing a thin t-shirt, or just on your bare skin. If you want to wear sweaters under your jacket later, just add about 1 cm (half an inch) to your number.
Mistake #2: Trusting Your T-Shirt Size
Just because your favourite shirt says "Medium" does not mean you need a Medium jacket. Leather jackets are meant to fit closer to your body than normal coats.
How to fix it: Ignore the tags on your clothes. Let the tape measure tell you the truth!
Mistake #3: Using Bra Size Instead of Chest Size (For Women)
Your bra size (like 34C) is not your jacket size! The number on your bra only measures your ribs, not your full chest.
How to fix it: Forget the bra tag. Use a soft tape measure around the biggest part of your chest. That is the number you need.
3. How to Measure Yourself Easily

Grab a soft tape measure! It only takes two minutes. Here are the four things you need to measure:
| Body Part | How to Do It | Why It Matters |
|---|---|---|
| Chest | Wrap the tape around the biggest part of your chest, right under your arms. Keep it flat. | This is the most important number! It tells you your main jacket size. |
| Shoulders | Measure across your back, from one shoulder edge to the other. | A jacket that fits your shoulders looks super sharp and neat. |
| Sleeves | Measure from the top of your shoulder down to your wrist. Keep your arm a little bent. | This makes sure the sleeves are not too short or too long. |
| Length | Measure from the bottom of your neck down to your belt. | This helps if you want a long trench coat or a short jacket. |
Great Tip: Stand up straight and breathe normally. Do not suck your tummy in! If you need more help, look at our easy jacket measuring guide.
4. How Should It Feel?
When your new jacket arrives in the mail, how should it feel when you put it on? Here is a quick checklist:
- Shoulders: The top seam should sit right on the edge of your shoulder. It should not fall down your arm.
- Chest: You should be able to zip it up comfortably. If you can fit a giant basketball inside, it is too big. If you cannot zip it at all, it is too small.
- Sleeves: The end of the sleeve should sit right at your wrist. It should not cover your hands.
- Armpits: You should be able to move your arms easily without the jacket pinching you.
- Length: For cool styles like bomber jackets and café racers, the bottom of the jacket should sit right around your belt. For big leather coats, it goes down to your legs.
Remember, real leather stretches a tiny bit as you wear it. If it feels just a little snug on day one, that is perfect! It will be incredibly comfortable in a week.
5. Size Tips for Men

- Chest is king. For almost all men's leather jackets, your chest number is the most important. Check that first!
- Are you tall? If you are over 183 cm (6 feet) tall, normal sleeves might be too short. Look at our tall men's jackets so it fits perfectly.
- Don't buy a huge size just for sweaters. Our jackets already have a little room for a light sweater. If you buy a massive size, you will look like you are wearing a box!
- Check the shoulders. If the shoulders fit great, the rest of the jacket will look amazing.
6. Size Tips for Women
- Measure your full chest. Put the tape measure around the biggest part of your bust, not under it. This is the secret to a great fit for women's leather jackets.
- Think about the style. A cute cropped jacket stops at your waist. A long leather trench coat goes down to your knees. Pick the look you love!
- Are you short? If you are under 163 cm (5 feet 4 inches), regular jackets might be too long. Check out our petite women's jackets made just for you!
- The waist is important. Women's jackets curve in at the waist. Make sure the jacket curves right where your tummy curves.
7. What If You Are Between Sizes?
Does your tape measure say you are right in the middle of a Medium and a Large? Do not panic! Here is what to do:
- If you like a tight, cool look: Pick the smaller size. Real leather will stretch a little bit and hug your body perfectly.
- If you like to wear thick sweaters: Pick the bigger size. This is a very smart choice for warm winter jackets and women's winter coats.
- When in doubt: Go one size up!
