How to Measure Chest Size for a Jacket (Step-by-Step)
Step 1: Stand Naturally
Stand upright with arms relaxed at your sides. Wear a lightweight T-shirt or a simple shirt, but do not wear bulky clothing to ensure accurate measurements.
Step 2: Wrap the Tape Around Your Chest
Position the measuring tape under your armpits, around the fullest part of your chest (typically just above the nipple line). Ensure the tape is parallel to the floor and snug but not tight.
Step 3: Record the Measurement
Note the number in inches or centimetres. This is your chest size, the most critical measurement for determining jacket size.
How to Measure Jacket Size for a Suit
Suit jackets require precise measurements for a tailored fit. Follow these additional steps:
- Shoulder Width: Measure from the edge of one shoulder (where the arm meets the torso) to the other.
- Sleeve Length: Start at the base of your neck, run the tape over your shoulder, and down to your wrist bone.
- Jacket Length: Measure from the base of the neck down to your hips (typically 25–30 inches for men, 20–25 inches for women).
How to Measure Men’s Jacket Size
Men’s jackets are sized by chest measurements (e.g., 40R, 42L). Here’s how to convert your measurements:
- Use your chest size (e.g., 40 inches).
-
Determine your fit type:
- Regular (R): Standard fit for average builds.
- Short (S): For torsos shorter than 5’8”.
- Long (L): For torsos taller than 6’2”.
How to Measure Women’s Jacket Size
Women’s jacket sizes often use numeric sizing (e.g., 6, 8, 10) or letters (S, M, L). Follow these tips:
- Chest: Measure the fullest part of your bust.
- Waist: Measure the narrowest part of your torso.
- Hips: Measure the fullest part of your hips.
- Compare measurements to the brand’s size chart, as women’s sizing can vary widely.
Pro Tips for Accurate Measurements
- Double-check: Measure twice to confirm consistency.
- Posture Matters: Stand naturally—don’t suck in your stomach or puff out your chest.
- Consider Layering: If you plan to wear thick sweaters under your jacket, add 1–2 inches to your chest measurement.
