Corozo Button Sizes – Chart in Ligne and Millimetres

Polkom
Размери на корозо копчета – таблица в линии и милиметри

Corozo button sizes are given in ligne (L), where 1L = 0.635 mm. The most commonly used sizes are 16L–18L (about 10–11.5 mm) for shirts, 24L (about 15 mm) for jacket sleeves, 30L–32L (about 19–20 mm) for jacket fronts and 36L–44L (about 23–28 mm) for coats. Because corozo is cut from the nut of the tagua palm, the largest diameters and thicknesses are limited by the size of the nut itself.

What a ligne (L) means

The ligne is a traditional unit of measurement in button manufacturing. It comes from old French and German practice and is still used today by manufacturers and tailors all over the world. The formula is simple: diameter in millimetres = number of lignes × 0.635. Conversely: number of lignes = diameter in mm ÷ 0.635. For example, a 32L button is 32 × 0.635 = 20.32 mm.

Corozo button size chart

Ligne (L) Diameter (mm) Typical use
14L 8.9 Button-down collar, small details
16L 10.2 Shirts, blouses, cuffs
18L 11.4 Shirts, skirts, light knitwear
20L 12.7 Blouses, pockets, children's clothing
22L 14.0 Knitwear, trousers
24L 15.2 Jacket sleeves, waistcoats, cardigans
26L 16.5 Waistcoats, knitwear
28L 17.8 Light jackets, cardigans
30L 19.1 Jacket front
32L 20.3 Jacket and blazer front
36L 22.9 Trench coats, light coats
40L 25.4 Coats
44L 27.9 Heavy coats and outerwear

The chart is a guide. The final size depends on the pattern, the fabric thickness, the buttonhole length and the brand's style.

Why corozo has a size limit

The tagua nut is roughly the size of a hen's egg and has a hollow inside. Buttons are cut from the dense zone, so the thickness and diameter of the blank are limited. Small and medium sizes are produced without any problem, while in the largest sizes for coats the choice of models and thicknesses is narrower. If you need a very large or very thick button, discuss it in your inquiry – sometimes the solution is a different profile or a combination with horn buttons.

How to measure a button correctly

  1. Use a calliper, not a ruler – a difference of half a millimetre is already a different size.
  2. Measure the widest part of the button, including the rim.
  3. For shank buttons, measure only the diameter of the face, without the shank.
  4. Also measure the thickness – it matters for the buttonhole and the look of the button.
  5. Convert the millimetres to lignes and round to the nearest standard size.

Buttonhole size

The buttonhole must be slightly longer than the button's diameter so that the button passes through freely. A practical rule is buttonhole length = diameter + button thickness. For thick corozo buttons with a domed profile, add a little more, otherwise buttoning will be difficult and the buttonhole will fray faster. Always make a test buttonhole on the actual fabric.

Recommended sizes by garment type

Shirts

Front and cuffs 16L–18L, button-down collar 14L. Corozo for shirts is thinner, with four holes and a slight rim.

Jackets and suits

Front 30L–32L, sleeves 24L. Double-breasted jackets often have 32L on the front and an inside button of 24L or smaller. You will find more details in our men's buttons section.

Waistcoats

24L–26L, denser, usually with four holes.

Coats

36L–44L depending on volume and style. Inside buttons are added for double-breasted coats.

Knitwear and cardigans

22L–28L, often with a more pronounced profile that sits well on the knit.

Thickness and profile

Two buttons with the same diameter can look completely different because of thickness and profile. A flat, thin button is discreet, while a thick one with a rim or domed centre is more noticeable. Corozo allows different profiles – flat, rimmed, concave, domed. When ordering, state the desired profile in addition to the ligne size, or send a sample.

How to specify the size in the technical sheet

Button size mistakes most often come from an incomplete specification. In the model's technical sheet, record for each button:

  • the size in ligne and in millimetres, for example 32L / 20.3 mm;
  • the type – two or four holes, or a shank;
  • the profile and thickness;
  • the colour and finish – natural, dyed, matt, polished;
  • the position on the garment – front, sleeve, pocket, inside button;
  • the number of buttons of this size per garment, including spares.

Such a sheet lets the button manufacturer and the garment factory work from the same information and reduces the risk of sizes being mixed up during sewing. It is a good idea to attach a photo or sketch of the garment with the positions marked.

A set of sizes for one garment

A garment usually uses two or three sizes of the same model: for example 32L for the front and 24L for the jacket sleeves, plus a spare button. All sizes should ideally come from one model and one dye lot so they look like a set. State in your inquiry the number of buttons of each size per garment and the total number of garments.

FAQ

Frequently asked questions

How many millimetres is a 24L corozo button?
A 24L button has a diameter of about 15.2 mm, since one ligne equals 0.635 mm. This is the typical size for the sleeves of a men's jacket, for waistcoats and for some knitted cardigans. When ordering, it is a good idea to also state the thickness or profile, because two 24L buttons can look different depending on their shape.
What is the largest corozo button size?
The size is limited by the nut of the tagua palm from which the button is cut. That is why corozo is mainly available in small and medium sizes, while in the largest diameters for coats the choice of models and thicknesses is more limited. If you need a very large button, describe it in your inquiry and we will suggest a suitable option.
How do I convert millimetres to lignes?
Divide the diameter in millimetres by 0.635 and round to the nearest standard size. For example, a button with a diameter of 20 mm is about 31.5 lignes, which in practice corresponds to 32L. Measure the widest part of the button with a calliper, including the rim, and for a shank button only the face without the shank.
