Measure Button Ligne in the Garments Industry

In the garments industry, buttons are categorized by their size, which is commonly measured in a unit called "ligne" (pronounced "line"). Understanding how to measure button ligne is essential for designers, merchandisers, and manufacturers to ensure proper garment design and functionality. This guide explains the concept of button ligne and how to measure it accurately.

 

What is a Ligne?

The ligne is a traditional unit of measure used specifically for buttons. It is a standard size measurement commonly adopted in the garment and accessory industry.

• 1 ligne = 0.635 mm (or approximately 1/40 inch).
• It originated in France and is still widely used globally.

The larger the ligne number, the bigger the button. For example:

• A 16 ligne button is smaller than a 40 ligne button.

 

Why is Measuring Ligne Important?

1. Design Compatibility: Button size affects the garment's overall appearance and functionality.
2. Machine Compatibility: Sewing machines for button attachment require precise button size specifications.
3. Buyer Requirements: Buyers often specify button sizes in ligne in their tech packs.

 

How to Measure Button Ligne

Follow these steps to measure the button's ligne size accurately:

1. Tools Needed

• A standard ruler (preferably with millimeters).
• A caliper for precise measurements.
• A ligne-to-mm conversion chart (optional).

2. Measure the Diameter

• Place the button on a flat surface.
• Measure across the widest part of the button, excluding the shank (if present).
• Note the diameter in millimeters.

3. Convert Millimeters to Ligne

• Use the formula:
  Button Ligne = Diameter in mm ÷ 0.635
• Alternatively, refer to a conversion chart:
• 12 ligne = 7.62 mm
• 14 ligne = 8.89 mm
• 16 ligne = 10.16 mm
• 20 ligne = 12.7 mm
• 24 ligne = 15.24 mm
• 32 ligne = 20.32 mm

 

Example Calculation

Given:

A button has a diameter of 15.24 mm.

Step 1: Apply the formula

Button Ligne = 15.24 ÷ 0.635

Step 2: Perform the calculation

Button Ligne = 24

Thus, the button is a 24-ligne button.

 

Tips for Accurate Measurement

1. Use Calipers: For small or intricate buttons, a caliper provides more precise measurements than a ruler.
2. Account for Tolerances: Always check buyer specifications for acceptable size tolerances.
3. Measure Multiple Samples: Measure several buttons from the same batch to ensure consistency.

 

Applications of Button Ligne Measurement

1. Shirts and Blouses: Typically use 14-20 ligne buttons.
2. Suits and Coats: Larger buttons, such as 32-40 ligne, are common.
3. Accessories: Ligne sizes are also used for button-like components in bags and shoes.

 

Conclusion

Measuring button ligne is a straightforward process that plays a critical role in the garments industry. Accurate measurement ensures that buttons fit their intended purpose, align with design specifications, and meet buyer expectations. By understanding the ligne system and using the correct tools, you can streamline button selection and enhance garment production.
