Choosing the right jacket size can be tricky, especially when you can't try it on. This guide offers simple ways to check your ideal size using your height, armspan, and a t-shirt. Whether you're shopping vintage, online, or from overseas, this will help you find the right fit with confidence.
✅ Use Armspan and Height to Estimate Shoulder and Sleeve Fit
Did you know your armspan (fingertip to fingertip) is roughly equal to your height? This relationship gives you a quick clue to whether a jacket’s sleeve length and shoulder width will fit well.
🔍 Example: If you're 170cm tall, your armspan is likely also around 170cm.
Look for jackets with a shoulder width of ~45cm and sleeve length of ~60cm for a balanced fit.
👕 Measure Your Favorite T-Shirt: Shoulders & Width
Use a t-shirt that fits you well to estimate ideal jacket measurements.
🔸 Shoulder Width
- Lay the t-shirt flat
- Measure between the seams at the top of the shoulders
🔸 Chest Width (Pit to Pit)
- Measure from underarm to underarm (pit to pit)
- This value gives you a great idea of comfortable jacket width
💡 Pro tip: Choose a jacket with a similar or slightly larger width than your favorite tee.
📏 Understand Jacket Length by Visualizing Body Zones
The jacket’s back length (measured from the neck to bottom hem) determines how it fits your silhouette. Use your buttocks as a reference to estimate ideal jacket length.
| Back Length (cm) | Visual Style |
|---|---|
| 60–65cm | Waist-length, cropped fit |
| 70–75cm | Covers the hips, standard length |
| 80cm+ | Below the hips, long silhouette |
👀 Choose length based on whether you prefer cropped, classic, or longline looks.
🧠 Recap: Easy Jacket Size Estimation Hacks
- Armspan ≒ Height — helps estimate shoulder/sleeve
- T-Shirt shoulder seams — gauge shoulder fit
- Underarm width (pit-to-pit) — great chest size reference
- Back length = where it falls on your body — imagine waist, hips, or below
