Suit jacket sleeves should end at your wrist bone so that about 0.25–0.5 inch (roughly 0.5–1.5 cm) of your dress shirt cuff shows when your arms are relaxed at your sides.

Ideal sleeve position

  • The jacket cuff should sit right at the prominent wrist bone, not on your hand and not up your forearm.
  • With your arms straight and relaxed, you should clearly see a sliver of shirt cuff—think the width of a pencil, up to about a fingertip’s width.

Shirt vs jacket relationship

  • Dress shirt sleeves should themselves reach to the wrist bone or the base of the thumb, so they just “kiss” the hand without covering the knuckles.
  • Once the shirt is correct, tailor the jacket so it finishes slightly higher, letting that subtle cuff peek out for a clean, intentional look.

Common mistakes to avoid

  • Sleeves too long: fabric bunching at the hand or covering the knuckles makes the suit look oversized and sloppy.
  • Sleeves too short: no shirt cuff visible and exposure of your forearm when moving can make the jacket look small or “grown out of.”

Small style variations

  • Classic look: about 0.5 inch of shirt cuff showing—timeless and safe for business and formal events.
  • Slightly fashion-forward: closer to 0.25 inch for a cleaner, tighter silhouette, or up to 0.75 inch if you want to show off a watch and cuffs more.
