How to Measure the Widest Part of Your Torso
This diagram shows the two most common measuring points for a SUITBAE jacket fit. You must always size from the widest part of your upper body, whether that is the chest or the belly. This ensures the jacket sits cleanly and avoids pulling or strain.
Black Line — Standard Torso Measurement
The black line shows the position many men will measure at: around the upper chest and back. If this is the widest point of your torso, this measurement determines your jacket size.
Red Line — Belly Measurement (If This Is Wider)
The red line shows where men with a larger stomach should measure instead. If your belly measurement is bigger than your chest, this becomes your true sizing number.
Example:
Chest: 44″
Belly: 47″
→ Your jacket size is based on 47″.
SUITBAE Recommendation for Bigger Builds
If your belly is larger than your chest, you have two valid choices:
- Size to the widest measurement (jacket closes cleanly, best for weddings and photos).
- Size to your chest for sharper shoulders (jacket worn open, looks very smart with a waistcoat).
SUITBAE waistcoats tighten by up to 2 inches, so even if you size to the belly, the waistcoat will still pull in neatly for shape.
2. Waist (Trousers) – The Jeans Rule
Suit trousers sit higher than jeans, so your jean size is the best starting point.
Simple rule:
- Jeans fit comfortably → order the same size.
- Jeans feel snug → order one size up.
All SUITBAE trousers include a hidden stretch panel that flexes up to 3 inches.
Examples:
- 34" jeans (comfortable) → 34" trousers
- 34" jeans (tight) → 36" trousers
- 40" jeans → 40" trousers (flex to 43")
3. Broad Shoulders vs Bigger Belly – Which Size Wins?
If you have broad shoulders:
- Size to the shoulders and chest.
- The waist can be taken in by a tailor.
If your belly is larger:
- Size to the largest torso measurement.
- Or choose the open-jacket approach for a sharper shoulder fit.
If you're slim or athletic:
- Use your true chest measurement.
- The waistcoat adjuster will refine your shape.
4. SUITBAE vs High Street Sizing
High street stores usually stop around a 52" chest. SUITBAE stocks up to a 58" chest and 52" waist.
We use true measurements: The number you measure is the number you order.
- 44" chest → Size 44
- 50" chest → Size 50
- 56–58" chest → Size 56–58
