For Lee jeans, the button size is usually the standard jeans front-button size, which commonly falls around 17–18 mm in diameter, but it can vary by style and production run. Lee’s size charts focus on waist and hip measurements rather than the button itself.

What this means

  • If you need a replacement button , measure the old one across the widest part.
  • If you need the jeans size , use the waist size on the label, such as 30, 32, or 34.
  • If you’re asking about a button fly style, the button specs can differ from regular jeans buttons.

Best practical check

  • Compare the button to a ruler in millimeters.
  • Look for the style name or product code inside the waistband.
  • Match that style to the product listing or size chart.

If you meant a specific Lee jeans model, the exact button size can be narrowed down from that style’s listing.
