How to

1. Put on the dress shirt you will actually wear under the jacket and fasten the cuffs. If the shirt sleeves are too short or the cuffs slide onto your hands, judging the jacket in isolation can give a misleading result. Include your usual wristwatch if you wear one.
2. Put the jacket on, settle its shoulders and let both arms hang naturally at your sides. Do not check sleeve length with your arms stretched forward or your wrists flexed. Look at where the jacket hem meets each wrist in a relaxed standing position.
3. Look at the amount of visible shirt cuff. Proper Cloth suggests approximately 0.25–0.50 inch (0.6–1.3 cm) for a versatile look, but notes that more conservative styles may reveal less. Use the measurement as a reference, not an unbreakable rule.
4. Check whether the jacket sleeve covers the heel of your palm. Proper Cloth describes that as too long. On the other hand, more than one inch of cuff showing with the arms relaxed may appear short for a conventional tailored suit.
5. Check each arm separately, then bend your elbows and reach gently forward. It is normal for more cuff to show in motion. Proper Cloth explains that differences in shoulder level or arm length can justify adjusting left and right sleeve lengths individually.
6. Before altering the sleeves, inspect the brand's measuring method. Charles Tyrwhitt measures its jacket sleeve from shoulder to cuff, whereas Proper Cloth describes a different starting point for dress-shirt sleeves. Do not compare the two numbers directly, and ask a tailor about working buttonholes before requesting major adjustments.

One more tip

Exposing about 0.25–0.50 inch (0.6–1.3 cm) of shirt cuff is a common Proper Cloth style guideline, not a mandatory rule. Brands may measure sleeves from different starting points, so compare how garments actually fit rather than treating chart figures as interchangeable. The 2020 Permanent Style fit video demonstrates jacket sleeves, shoulders and waist together. Its example is illustrative; use your own shirt length and preferences.
